EP-SE416T3 is the entry point to the 2,000 N\u00b7m brake tier in the Korea Ever-Power SE series. Among the three SE units sharing a 2,000 N\u00b7m spring brake \u2014 EP-SE416T3 (i=87\u2013255, 1,100 kg), EP-SE417T3 (i=123\u2013365, 1,450 kg), and EP-SE418T3 (i=166\u2013364, 2,200 kg) \u2014 it is the fastest-travelling unit: i=87 at 3,000 rpm gives 34.5 rpm sprocket output, compared to EP-SE417T3\u2019s 24.4 rpm at i=123 and EP-SE418T3\u2019s 18.1 rpm at i=166. This makes EP-SE416T3 the right track drive planetary gearbox for machines in the 1,200\u20132,000 tonne class that must both hold adequately with a 2,000 N\u00b7m spring brake and travel at reasonable speed between work positions. Korea Ever-Power calculates the exact boundary between EP-SE415T3, EP-SE416T3, and EP-SE417T3 for your machine same day, no charge, before any order commitment. The 17 SE series units covered on this site span 254\u00d7 in rated torque \u2014 from SE400T1 (1,300 N\u00b7m) to SE419T3 (330,000 N\u00b7m) \u2014 all sharing the same rotating-housing planetary gearbox architecture. EP-SE416T3 at 160,000 N\u00b7m is the bridge between the 1,200 N\u00b7m and 2,000 N\u00b7m brake tiers in this range.<\/p>\n<\/section>\n

First 2,000 N\u00b7m Brake in the SE T3 Series \u2014 and the Fastest Travel Among All 2,000 N\u00b7m Units<\/h2>\n

In the Korea Ever-Power SE series as presented on this site, spring brake torque steps up progressively with machine class: SE413T3 at 610 N\u00b7m, SE414T3 at 1,200 N\u00b7m, SE415T3 at 1,200 N\u00b7m. EP-SE416T3 is the point where the brake torque makes its first crossing to 2,000 N\u00b7m \u2014 a 66.7% increase over EP-SE415T3. This brake rating is shared by EP-SE417T3 and EP-SE418T3, but EP-SE416T3 holds a distinction those heavier units cannot claim: it is the fastest-travelling unit in the 2,000 N\u00b7m brake tier.<\/p>\n

\n
\n
Why 2,000 N\u00b7m Is the Correct Brake for 160,000 N\u00b7m<\/div>\n

The spring brake must provide adequate hold on the steepest operational gradient for the machine weight class. At 160,000 N\u00b7m and the 1,200\u20132,000 tonne machines served by EP-SE416T3, the required hold at typical operational gradients of 10\u201315\u00b0 exceeds what EP-SE415T3’s 1,200 N\u00b7m brake can provide at the available ratios. At i=140 (a typical working ratio for this class), 2,000 \u00d7 140 = 280,000 N\u00b7m per drive; two drives provide 560,000 N\u00b7m combined. For a 1,500-tonne machine at 10\u00b0 with 700 mm sprocket radius: required hold = 1,500,000 \u00d7 9.81 \u00d7 sin10\u00b0 \u00d7 0.70 \/ 2 = 899,000 N\u00b7m combined. The spring brake at i=140 provides 560,000 N\u00b7m combined \u2014 supplementary counterbalance valves are required at this weight and gradient at i=140, but at higher ratios (i=200\u2013255) the brake alone provides 800,000\u20131,020,000 N\u00b7m combined, covering the requirement without supplementary valves. Korea Ever-Power calculates this for your specific machine weight, ratio, and gradient.<\/p>\n<\/div>\n

\n
i=87: Fastest Travel Among 2,000 N\u00b7m SE Units<\/div>\n

The three SE units with 2,000 N\u00b7m brake in the series covered here are EP-SE416T3 (i=87\u2013255), EP-SE417T3 (i=123\u2013365), and EP-SE418T3 (i=166\u2013364). Their minimum ratios \u2014 which determine the fastest achievable travel speed \u2014 are i=87, i=123, and i=166 respectively. At 3,000 rpm motor input: EP-SE416T3 achieves approximately 34.5 rpm at i=87, versus 24.4 rpm for EP-SE417T3 at i=123. That is 41% faster at maximum travel speed. For machines that need to reposition between work zones at reasonable speed \u2014 large mining excavators repositioning across a bench, mobile crushing plants moving between faces \u2014 the ability to travel at 34.5 rpm versus 24.4 rpm represents a meaningful reduction in non-productive repositioning time. EP-SE418T3’s minimum ratio is i=166, giving only 18.1 rpm. EP-SE416T3 is nearly double the repositioning speed of EP-SE418T3, while sharing the same 2,000 N\u00b7m brake rating.<\/p>\n<\/div>\n

\n
i=87\u2013255: Widest Ratio Span at 2,000 N\u00b7m<\/div>\n

EP-SE416T3’s ratio span i=87\u2013255 = 2.93\u00d7 from minimum to maximum. EP-SE417T3’s span is i=123\u2013365 = 2.97\u00d7 (slightly wider in percentage, but starting from a much higher minimum). EP-SE418T3’s span is i=166\u2013364 = 2.19\u00d7. In practical terms, EP-SE416T3’s 2.93\u00d7 span allows the machine to travel 2.93\u00d7 faster at i=87 than at i=255 without changing motor displacement or circuit settings. This gives the operator a wide speed range from fast repositioning at low ratio to ultra-slow precision positioning at high ratio, from a single fixed motor displacement. For machines that need to switch between fast repositioning and slow precise work positioning \u2014 large crawler cranes moving between lifts, for example \u2014 EP-SE416T3’s wide ratio span at the 2,000 N\u00b7m brake level is directly operationally beneficial.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

<\/p>\n

\n

Positioned Between SE415T3 and SE417T3 \u2014 When Neither Adjacent Unit Is the Right Fit<\/h2>\n

EP-SE416T3 exists because there is a real machine class \u2014 approximately 1,200\u20132,000 tonnes \u2014 where EP-SE415T3 (110,000 N\u00b7m, 1,200 N\u00b7m brake) is insufficient, and EP-SE417T3 (220,000 N\u00b7m, 2,000 N\u00b7m brake, 1,450 kg) is more than required in both torque and weight. EP-SE416T3 at 160,000 N\u00b7m, 2,000 N\u00b7m brake, and 1,100 kg fills that gap. Here is how the selection logic works across these three units.<\/p>\n

\n
\n
When EP-SE415T3 is Not Enough<\/div>\n

EP-SE415T3 at 110,000 N\u00b7m with 1,200 N\u00b7m brake is specified for machines up to approximately 1,200\u20131,500 tonnes at typical operating gradients, with appropriate safety factors. When the machine weight reaches 1,500+ tonnes, or when the spring brake adequacy calculation shows the 1,200 N\u00b7m brake insufficient at the required ratio and gradient, EP-SE416T3 is the next step. The torque increase (+45.5%) gives the drive margin at the higher machine weight, and the 2,000 N\u00b7m brake provides 66.7% more emergency hold \u2014 addressing both the drive requirement and the parking safety requirement simultaneously. A 250 kg weight penalty (+29.4% vs SE415T3) is the trade-off, requiring a 1,500 kg crane versus 1,200 kg for SE415T3.<\/p>\n<\/div>\n

\n
When EP-SE417T3 Is More Than Required<\/div>\n

EP-SE417T3 at 220,000 N\u00b7m with 1,450 kg is specified for machines typically above 2,000 tonnes. When machine weight and drive torque calculation confirms that 160,000 N\u00b7m provides adequate safety margin at the required gradient \u2014 but 220,000 N\u00b7m would be excessive capacity at significant weight cost \u2014 EP-SE416T3 at 1,100 kg saves 350 kg per drive (700 kg across two drives). This weight saving affects the machine’s own ground pressure, payload capacity, and transport logistics. An OEM specifying EP-SE417T3 for a 1,500-tonne machine is paying for 37.5% more torque capacity and 32% more weight than the application requires. Korea Ever-Power’s same-day engineering calculation shows which unit provides adequate safety margin for the specific machine, gradient, and dynamic factor.<\/p>\n<\/div>\n

\n
The Fast-Travel Advantage \u2014 Unique to EP-SE416T3 at This Brake Level<\/div>\n

An OEM whose machine weight falls in the EP-SE417T3 range (2,000+ tonnes) must accept that unit’s i=123 minimum ratio \u2014 meaning the machine cannot travel faster than 24.4 rpm sprocket output. An OEM whose machine weight falls at the EP-SE416T3 boundary (1,200\u20132,000 tonnes) can specify EP-SE416T3 at i=87 and achieve 34.5 rpm sprocket output \u2014 41% faster. For a 1,500-tonne machine that is at the lower end of the 2,000 N\u00b7m brake requirement, EP-SE416T3 provides both the required brake rating and a meaningfully faster repositioning speed than EP-SE417T3 would allow at i=87. This is why EP-SE416T3 exists as a distinct model rather than simply being replaced by EP-SE417T3 in the SE series catalogue. For machine designers working at the 1,200\u20132,000 tonne boundary, Korea Ever-Power\u2019s same-day engineering response includes the calculated tractive force and brake requirement for both EP-SE416T3 and EP-SE417T3 so the designer can see exactly which criterion (torque or brake) each unit satisfies and what the actual safety margin is against the design limit in each case. This transparency allows a fully informed selection without having to over-specify to the next unit \u201cjust to be safe.\u201d<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

Applications \u2014 1,200 to 2,000 Tonne Machine Class<\/h2>\n

EP-SE416T3 at 160,000 N\u00b7m and 2,000 N\u00b7m brake serves the machines where EP-SE415T3 at 110,000 N\u00b7m and 1,200 N\u00b7m brake is insufficient, but where EP-SE417T3 at 220,000 N\u00b7m and 1,450 kg would be over-specified. The fast minimum ratio i=87 makes it particularly suited to machines that must reposition frequently between work stations at reasonable speed.<\/p>\n

\n
\n

Large Mining Excavators \u2014 120\u2013150 Tonne Class<\/h3>\n

Mining hydraulic excavators in the 120\u2013150 tonne operating weight class \u2014 heavy-duty machines used for primary overburden removal, ore loading into 100-tonne haul trucks, and deep trench excavation \u2014 require EP-SE416T3 when machine weight and operating gradient produce drive torque demands that exceed EP-SE415T3’s 110,000 N\u00b7m. At typical operating ratios of i=100\u2013140, the 2,000 N\u00b7m spring brake provides adequate hold on bench gradients of up to 12\u00b0 for machines in this weight class. The wide ratio range i=87\u2013255 allows the operator to use low ratios during fast tramming between benches and high ratios during precision digging face positioning, without hydraulic motor changeover.<\/p>\n<\/div>\n

\n

Crawler Cranes \u2014 500\u20131,000 Tonne Lift Class<\/h3>\n

Crawler cranes with lift ratings of 500\u20131,000 tonnes have gross vehicle weights ranging from 400 to 1,000+ tonnes in full counterweighted configuration. EP-SE416T3 serves this crane class when machine weight at worst-case gradient exceeds EP-SE415T3’s 110,000 N\u00b7m capacity and when EP-SE417T3 at 1,450 kg would add unnecessary weight that affects the crane’s pick-and-carry chart. The 2,000 N\u00b7m brake at i=180\u2013255 provides 360,000\u2013510,000 N\u00b7m per drive hold \u2014 adequate for crane type-approval parking safety requirements at 12\u201315\u00b0 slope for this machine weight class. Fast travel at i=87 enables efficient pick-and-carry repositioning.<\/p>\n<\/div>\n

\n

Mobile Crushing and Screening Plants \u2014 100\u2013150 Tonne<\/h3>\n

Heavy mobile crushing and screening plants in the 100\u2013150 tonne operating weight class \u2014 machines that reposition frequently across quarry and mine sites \u2014 benefit particularly from EP-SE416T3’s wide ratio span. During tramming across level or gently sloping ground, i=87\u2013100 provides fast repositioning. During final approach to the rock face or aggregate stockpile, i=200\u2013255 provides the slow precision positioning needed without jarring the plant structure. The 2,000 N\u00b7m brake at high ratios ensures the plant remains stationary during crushing operations despite vibration forces. High-frequency vibration from the crushing process is fully absorbed by EP-SE416T3’s carburised gear set and taper roller main bearing.<\/p>\n<\/div>\n

\n

Large Rotary Drilling Rigs and Piling Machines<\/h3>\n

Rotary drilling rigs and piling machines in the 80\u2013120 tonne class \u2014 used for deep foundation drilling, anchor installation, and caisson piling \u2014 require precise, high-torque travel drives that hold position reliably during drilling operations. EP-SE416T3’s 2,000 N\u00b7m brake at operating ratios of i=180\u2013255 provides 360,000\u2013510,000 N\u00b7m per drive static hold, keeping the rig mast stationary during drilling cycle without hydraulic circuit pressure maintenance. At i=87, the rig can tram between pile positions at a practical pace rather than the ultra-slow speed of higher-ratio units, reducing non-productive tramming time on dense urban piling sites where time is at premium.<\/p>\n<\/div>\n

Surface Miners and Large Trenchers<\/h3>\n

Continuous surface miners and large trenchers requiring 160,000 N\u00b7m for the propel drive \u2014 machines with cutter drum widths above 2 metres and machine weights approaching 150 tonnes \u2014 benefit from EP-SE416T3’s 100% duty cycle capability. The deep carburised gear set sustains continuous torsional loading without progressive micro-pitting at the gear tooth contact, which is the primary wear mechanism in continuous-duty applications. At these machine weights and cutting forces, the 2,000 N\u00b7m spring brake provides position hold during cutter head indexing operations when the machine must stop momentarily at high lateral resistance. Auxiliary tool drive gearboxes on these machines use agricultural-type multi-output gearboxes<\/a> on separate PTO circuits, independent of EP-SE416T3 travel drives.<\/p>\n<\/div>\n

Offshore and Marine Tracked Systems \u2014 Mid-Scale<\/h3>\n

Tracked crawler platforms in the 1,000\u20132,000 tonne payload range \u2014 used for offshore infrastructure installation, subsea maintenance platforms, and marine yard transport \u2014 require EP-SE416T3 when total system weight falls above EP-SE415T3’s service envelope. The dual-cone floating metal face seals sustain salt water immersion and high-pressure wash-down without oil contamination. Auxiliary winch and tensioner equipment on these platforms uses mga reducer sa worm gear<\/a> for self-locking cable hold, operating independently from the EP-SE416T3 travel drives. The dual-cone floating metal face seals sustain salt spray, high-humidity marine atmosphere, and high-pressure wash-down conditions without requiring seal maintenance between deployment cycles.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

SE415T3 vs SE416T3 vs SE417T3 \u2014 Boundary Calculation Same Day<\/h3>\n

The most common EP-SE416T3 engineering enquiry is the boundary question: does this machine need SE416T3, or will SE415T3 suffice, or does it need SE417T3? Korea Ever-Power calculates all three simultaneously from your machine weight, gradient, dynamic factor, and target travel speed \u2014 and returns the comparison in a single same-day document, no charge, before any order commitment. Where the machine sits precisely at the SE415T3\/SE416T3 boundary, Korea Ever-Power identifies which specific parameter (torque or brake) drives the step-up requirement.<\/p>\n<\/div>\n

We supply travel drive systems for a fleet of 135-tonne hydraulic mining excavators operating in East African iron ore and coal operations. Korea Ever-Power confirmed EP-SE416T3 after our calculation showed the required drive torque for our worst-case 12\u00b0 bench gradient with a 1.6\u00d7 shock factor was approximately 148,000 N\u00b7m per drive \u2014 above EP-SE415T3’s 110,000 N\u00b7m but below EP-SE417T3’s 220,000 N\u00b7m. At i=130 (our standard working ratio), the 2,000 N\u00b7m spring brake provides 260,000 N\u00b7m per drive hold \u2014 sufficient for our 12\u00b0 parking gradient at 135-tonne machine weight without supplementary counterbalance valves. We had previously used a European supplier at higher unit cost and 16-week lead time. Korea Ever-Power delivered from stock in 11 days and the engineering document Korea Ever-Power provided \u2014 including the brake adequacy calculation for our specific gradient \u2014 was accepted by our client’s site safety team without any modification. At 1,350 hours across our eight-unit fleet, zero EP-SE416T3 failures. The i=87 minimum ratio means our machines reposition between benches 32% faster than our previous units, measurably reducing cycle time. We now keep one EP-SE416T3 unit in consignment stock at each site, replenished from Korea Ever-Power within 14 days. Korea Ever-Power\u2019s stage-separated parts catalogue means our mechanics can replace the brake disc pack or face seal kit in the field without returning the 1,100 kg unit to a workshop \u2014 the portability at this weight compared to larger SE units is genuinely practical at remote East African mine sites where workshop crane capacity is limited.<\/p>\n

We produce crawler cranes in the 600\u2013900 tonne lift class for marine and port infrastructure projects in the eastern Mediterranean. Our 750-tonne crane has a gross vehicle weight of approximately 550 tonnes in working configuration. Korea Ever-Power confirmed EP-SE416T3 at i=190 after confirming our drive torque requirement \u2014 550 tonnes on our 10\u00b0 type-approval ramp with 1.55\u00d7 factor \u2014 produced 142,000 N\u00b7m per drive, within EP-SE416T3’s capacity with 12.7% margin. The 2,000 N\u00b7m brake at i=190 provides 380,000 N\u00b7m per drive hold \u2014 our type-approval requires 2.0\u00d7 the maximum tramming torque from spring brake alone: 380,000 vs 142,000 = 2.68\u00d7, comfortably passing. At i=87, our crane repositions at approximately 34.5 rpm sprocket output \u2014 significantly faster than the 750-tonne class crane’s previous final drive that used a higher minimum ratio. On pick-and-carry operations, faster repositioning between lift positions has improved our on-site productivity measurably. At 900 hours on our current crane deployment in the Piraeus port expansion, zero EP-SE416T3 failures. Korea Ever-Power’s dimensional cross-reference confirmed direct replacement of our previous European final drive with no structural modifications.<\/p>\n

We operate a fleet of large mobile crushing and screening plants across granite quarries in Finland and Norway. Our primary plants are in the 130\u2013145 tonne operating weight range. The plants reposition frequently \u2014 typically 2\u20134 times per day as the quarry face advances \u2014 and must hold position reliably during crushing operations where the vibration forces are substantial. Korea Ever-Power specified EP-SE416T3 at i=115 for fast repositioning (26.1 rpm output at 3,000 rpm motor) and i=240 for slow face positioning (12.5 rpm). The 2,000 N\u00b7m brake at i=240 provides 480,000 N\u00b7m per drive hold \u2014 our engineering team verified this is adequate for our maximum site gradient of 8\u00b0 at 145 tonnes without supplementary valves. At \u221232\u00b0C winter temperatures, the low-temperature Viton seals specified in the factory option have maintained integrity across three full Finnish winters \u2014 zero oil contamination or seal failure. Crushing vibration at 100\u2013200 Hz frequency has produced no evidence of micro-pitting in oil samples after 1,600 hours of continuous operation. Korea Ever-Power’s 9-day delivery from stock was critical for our fleet roll-out schedule.<\/p>\n

Q<\/span>How do I decide between EP-SE415T3, EP-SE416T3, and EP-SE417T3 for my machine?<\/h3>\n

The decision involves two independent criteria: drive torque adequacy and brake adequacy. Drive torque: calculate the required tractive force per drive unit as (machine weight \u00d7 9.81 \u00d7 sin(gradient) \u00d7 dynamic shock factor) \u00d7 sprocket radius. If below 110,000 N\u00b7m, EP-SE415T3. If 110,000\u2013160,000 N\u00b7m, EP-SE416T3. If above 160,000 N\u00b7m, EP-SE417T3 or higher. Brake torque: calculate required spring brake hold as (machine weight \u00d7 9.81 \u00d7 sin(gradient) \u00d7 safety factor) \u00d7 sprocket radius \u00f7 2 drives \u00f7 ratio. If the required brake equivalent at your operational ratio requires above 1,200 N\u00b7m spring brake, EP-SE416T3 or higher. In many cases one criterion drives the selection \u2014 Korea Ever-Power calculates both criteria simultaneously from your machine weight, gradient, sprocket radius, shock factor, and target ratio, and identifies which unit each criterion requires. If the two criteria point to different units, the higher selection governs. This calculation is provided same day, no charge, before any order commitment. Korea Ever-Power also calculates the option cost savings of using EP-SE416T3 versus EP-SE417T3 for machines where EP-SE416T3 is technically adequate. A correctly specified track drive planetary gearbox saves both unit cost and installation weight \u2014 and at 1,100 kg versus 1,450 kg for EP-SE417T3, the 350 kg per drive saving across a two-drive machine is 700 kg of reduced ground pressure and transport weight, which may be significant for machines subject to strict gross vehicle weight limits or ground bearing pressure constraints on soft site soils.<\/p>\n<\/div>\n

\n

Q<\/span>EP-SE416T3 has i=87\u2013255. EP-SE417T3 starts at i=123. Can EP-SE416T3 genuinely travel faster at the same brake rating?<\/h3>\n

Yes, and the speed difference is substantial. At i=87 and 3,000 rpm motor input, EP-SE416T3 produces approximately 34.5 rpm sprocket output. At i=123 and 3,000 rpm, EP-SE417T3 produces 24.4 rpm. At a 700 mm sprocket radius, EP-SE416T3 travels at approximately 0.86 km\/h maximum versus EP-SE417T3’s 0.61 km\/h maximum \u2014 41% faster. Both units carry 2,000 N\u00b7m spring brakes. This difference in fast-travel speed is why EP-SE416T3 exists as a separate model: it serves machines in the 1,200\u20132,000 tonne class that need the 2,000 N\u00b7m brake (not satisfied by EP-SE415T3’s 1,200 N\u00b7m) but also benefit from faster travel (not available from EP-SE417T3’s i=123 minimum). For a mobile crusher repositioning 2\u20134 times per day across a quarry, 41% faster tramming speed has direct impact on productive versus non-productive time.<\/p>\n<\/div>\n

\n

Q<\/span>What oil volume, first-change procedure, and condition monitoring apply to EP-SE416T3?<\/h3>\n

EP-SE416T3 contains approximately 15\u201322 litres of gear oil depending on ratio configuration and motor adapter. Exact fill volume is on the Korea Ever-Power dimensional drawing. First oil change at 150 operating hours: drain warm, allow 20+ minutes for full drain to evacuate all three stages’ run-in particles, then refill with fresh API GL-5 VG 150 (below +15\u00b0C) or VG 220 (above +15\u00b0C). Subsequent changes: every 1,000 hours or annually. For fleet operators running multiple EP-SE416T3 units, ICP oil sampling every 500 hours is recommended to monitor wear particle trends. At 15\u201322 litres, sampling provides a clear elemental concentration reference. Establish elemental baseline at 150-hour first oil change when the unit is new and known good; compare all subsequent samples against this baseline. Korea Ever-Power can advise on elemental reference ranges for EP-SE416T3 units on request as part of the startup documentation package. For fleet operators running EP-SE416T3 across multiple machines on the same site, centralised oil sampling with samples dispatched to a common laboratory at each 500-hour interval provides the most cost-effective early-warning system. Korea Ever-Power\u2019s reference ranges allow the laboratory to flag any unit whose sample deviates from the baseline before the deviation becomes a failure event. At 1,100 kg, a unit identified with developing wear can be removed and replaced within a standard planned maintenance window using a 2-tonne site crane, without the major crane logistics that larger SE units require.<\/p>\n<\/div>\n

\n

Q<\/span>Is EP-SE416T3 a direct replacement for Rexroth GFT 160 T3 or equivalent Bonfiglioli units?<\/h3>\n

For triple-stage track drive units in the 160,000 N\u00b7m torque class, Korea Ever-Power provides a full dimensional cross-reference before any order \u2014 spindle bore diameter and fit class, drum OD, sprocket BCD, hydraulic port thread sizes, motor interface spigot, and brake pilot port \u2014 against your specific model number and ratio code. Provide the full model number with all suffix codes. Dimensions that match are confirmed explicitly; any dimension requiring a resolution path is flagged with the alternative. The cross-reference is provided same day and is a prerequisite for any EP-SE416T3 replacement order, ensuring there are no installation surprises at the machine site.

\u2605 First 2,000 N\u00b7m Brake in the SE T3 Series \u2014 and the Widest Ratio Range of Any 2,000 N\u00b7m Unit<\/div>\n

From EP-SE415T3 track drive planetary gearbox (110,000 N\u00b7m, 1,200 N\u00b7m brake) to EP-SE416T3, the spring brake makes its first jump to 2,000 N\u00b7m in the triple-stage SE series \u2014 a 66.7% increase. This is the brake rating shared by EP-SE417T3 and EP-SE418T3, but EP-SE416T3 adds something those larger units cannot: the ratio range starts at i=87, giving approximately 34.5 rpm output from a 3,000 rpm motor \u2014 41% faster at maximum travel speed than EP-SE417T3’s minimum ratio of i=123. Among all SE units carrying a 2,000 N\u00b7m brake, EP-SE416T3 has the lowest minimum ratio (i=87) and the widest ratio span (i=87\u2013255 = 2.93\u00d7), making it the most operationally versatile unit at this brake level. Torque increases +45.5% to 160,000 N\u00b7m, and weight reaches 1,100 kg (+29.4%), requiring a \u22651,500 kg crane for installation.<\/p>\n<\/div>","protected":false},"featured_media":849,"comment_status":"open","ping_status":"closed","template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[966],"product_tag":[],"class_list":["post-845","product","type-product","status-publish","has-post-thumbnail","product_cat-track-drive-planetary-gearbox","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/planetary-gearboxes.com\/ceb\/wp-json\/wp\/v2\/product\/845","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/planetary-gearboxes.com\/ceb\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/planetary-gearboxes.com\/ceb\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/ceb\/wp-json\/wp\/v2\/comments?post=845"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/ceb\/wp-json\/wp\/v2\/media\/849"}],"wp:attachment":[{"href":"https:\/\/planetary-gearboxes.com\/ceb\/wp-json\/wp\/v2\/media?parent=845"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/ceb\/wp-json\/wp\/v2\/product_brand?post=845"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/ceb\/wp-json\/wp\/v2\/product_cat?post=845"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/ceb\/wp-json\/wp\/v2\/product_tag?post=845"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
