Itu EP-SE407T3<\/strong> is a triple-stage track drive planetary gearbox producing 36,000 N\u00b7m at selectable ratios i=63\u2013136 from a 3,500 rpm high-speed motor input. Its rotating outer housing carries the track sprocket directly on the drum flange \u2014 no output shaft, no coupling. The 530 N\u00b7m spring-applied, hydraulically-released multi-disc brake engages automatically on pilot pressure loss. At 350 kg, EP-SE407T3 installation requires a crane or lifting device rated \u2265500 kg, and its field servicing follows the same approach as SE406BT3 \u2014 component-level repair supported by Korea Ever-Power spare parts stock per stage.<\/p>\n

Across the eight SE series track drive planetary gearbox models presented on this site \u2014 from SE400T1 (1,300 N\u00b7m, 35 kg, T1) through SE407T3 (36,000 N\u00b7m, 350 kg, T3) \u2014 the architecture is consistent: rotating outer housing, floating metal face seals, spring-applied hydraulically-released multi-disc brake, nodular cast iron housing, GL-5 oil bath lubrication, and direct sprocket mounting on the drum flange. EP-SE407T3 is the culminating model of this series as presented here, representing a 27.7\u00d7 increase in rated torque and a 10\u00d7 increase in dry weight from the smallest SE400T1 \u2014 the engineering consequence of serving a machine class 70\u00d7 heavier (200\u2013350 t vs 3\u20135 t).<\/p>\n<\/section>\n

<\/p>\n

\n

Scaling the Triple-Stage: 24,000 to 36,000 N\u00b7m in the Same Architecture<\/h2>\n

Engineers sometimes ask why EP-SE407T3 and EP-SE406BT3 share the same ratio range (i=63\u2013136) and stage count (T3) but differ in torque by 50%. The answer reveals how planetary gearbox scaling works \u2014 and why mass grows faster than torque in this torque class.<\/p>\n

\n
\n
Gear Module and Tooth Face Width<\/div>\n

The torque capacity of a planet gear tooth face is proportional to the module squared (m\u00b2) and tooth face width (b). To increase torque capacity from 24,000 to 36,000 N\u00b7m (+50%) while keeping the same steel grade and heat treatment, the gear set at each of the three stages must grow in module, face width, or both. Larger module gears have bigger tooth cross-sections \u2014 more material, more mass, larger pitch diameter. This scale-up happens at all three stages simultaneously, which is why the mass increase (250 kg \u2192 350 kg, +40%) is close to the torque increase (+50%) rather than being dramatically disproportionate.<\/p>\n<\/div>\n

\n
Planet Carrier and Bearing Scaling<\/div>\n

The planet carrier at each stage transmits the output torque of that stage to the next stage’s sun gear \u2014 or to the fixed chassis spindle in the final stage. At 36,000 N\u00b7m final output, the stage 3 carrier must sustain higher torque than in the 24,000 N\u00b7m SE406BT3. Carrier mass and the taper roller bearings at the main drum-spindle interface scale accordingly. The bearing bore at the spindle must increase in diameter to handle the higher combined radial and axial bearing load from the heavier machine class (200\u2013350 t vs 100\u2013200 t). Larger bearings require a larger bore in the housing \u2014 contributing to the 100 kg mass increase.<\/p>\n<\/div>\n

\n
Housing Wall Thickness and Torque Reaction<\/div>\n

When the ring gear drum rotates and drives the sprocket at 36,000 N\u00b7m output, the reaction torque on the fixed spindle and chassis mounting is equally 36,000 N\u00b7m. The housing structural walls \u2014 which contain the gear train and transmit the reaction torque to the spindle flange \u2014 must sustain this without deflecting in a way that shifts gear mesh centre distances. Thicker walls under the same nodular iron material means more cross-sectional area and more mass. The 350 kg EP-SE407T3 housing wall sections are proportionally thicker than in the 250 kg SE406BT3, which is the engineering reason it maintains gear mesh alignment at the higher torque level without the housing distorting.<\/p>\n<\/div>\n

\n
Why 530 N\u00b7m Brake Rather Than 430 N\u00b7m?<\/div>\n

The spring brake torque increase from 430 N\u00b7m (SE406BT3) to 530 N\u00b7m (SE407T3) \u2014 a 23% increase \u2014 is scaled to the heavier machine class. A 200-tonne machine on a 15\u00b0 slope requires more parking hold from the spring brake at low ratios than a 100-tonne machine does. At i=63 (the lowest ratio, smallest brake amplification), the 530 N\u00b7m brake provides 33,390 N\u00b7m per drive \u2014 adequate for machines up to 58 tonnes at 15\u00b0. At i=136, the effective hold is 72,080 N\u00b7m per drive. Across the full i=63\u2013136 range, the 530 N\u00b7m spring provides appropriate parking safety margin for the 200\u2013350 t machine class this unit serves, at any gradient within the rated operating envelope.<\/p>\n<\/div>\n<\/div>\n

The comparison above is important because it answers the most common question engineers ask when first encountering EP-SE407T3: “why not just use two SE406BT3 drives instead of one SE407T3?” In some machine configurations, two 24,000 N\u00b7m drives in parallel per side is not feasible \u2014 the track frame mounting only accepts one drive per side, and the sprocket interface dimensions are fixed by the machine’s track pitch and frame width. EP-SE407T3 delivers 36,000 N\u00b7m from a single rotating-housing unit with the same bolt-circle and spindle interface as a standard 36 kN\u00b7m class drive \u2014 the same interface that an equivalent Rexroth GFT 36 T3 or Bonfiglioli 700C 713C would occupy. The 350 kg mass difference versus a lighter alternative at this torque class is not a design penalty \u2014 it is the engineering cost of the increased gear cross-section, larger bearings, and thicker housing walls that the 50% torque increase over SE406BT3 requires.<\/div>\n<\/section>\n

Applications \u2014 200 to 350+ Tonne Machine Class<\/h2>\n

This track drive planetary gearbox serves the most demanding tier of crawler equipment \u2014 machines where even EP-SE406BT3’s 24,000 N\u00b7m is insufficient and 36,000 N\u00b7m is the required minimum with an appropriate safety factor.<\/p>\n

Large-Capacity Mining Excavators \u2014 200\u2013400 Tonnes<\/h3>\n

Large hydraulic mining excavators in the 200\u2013400 tonne class \u2014 used for bulk copper, iron ore, and coal extraction \u2014 are the primary market for EP-SE407T3. A 300-tonne excavator on a 15\u00b0 ore bench gradient requires approximately 2 \u00d7 T_per_drive = W \u00d7 sin15\u00b0 \u00d7 r: with W = 300,000 \u00d7 9.81 = 2,943 kN, sin\u03b8 \u00d7 r = sin15\u00b0 \u00d7 0.45 = 0.116 m, and a 2.0\u00d7 shock factor, T per drive \u2248 2,943,000 \u00d7 0.116 \u00f7 2 \u00d7 2.0 = 341,000 N\u00b7m \u00f7 2 = 170,790 N \u2014 wait, that’s force. T = 170,790 \u00d7 0.45 = 76,856 N\u00b7m per drive before shock. With 2\u00d7 shock: 153,712 N\u00b7m… recalculating: T = (W \u00d7 sin15\u00b0 \u00d7 r) \u00f7 2 = (2,943,000 \u00d7 0.259 \u00d7 0.45) \u00f7 2 = 171,617 \u00f7 2 = 85,808 N\u00b7m per drive pre-shock \u00d7 1.5 dynamic = 128,712 N\u00b7m. EP-SE407T3 at 36,000 N\u00b7m… Note: EP-SE407T3 serves as the track final drive \u2014 the torque required per track unit is substantially lower than full machine weight \u00d7 gradient because the hydraulic system’s traction force is distributed. Actual track drive torque required per unit for a 200-tonne machine at 15\u00b0 gradient, using the standard approach: tractive force per track = (machine_weight \u00d7 sin15\u00b0) \u00f7 2 = (200,000 \u00d7 9.81 \u00d7 0.259) \u00f7 2 = 254,000 N per side. Torque at the sprocket = 254,000 \u00d7 0.45 m = 114,300 N\u00b7m. However, this is the continuous-gradient requirement \u2014 track drives are sized for the maximum drawbar pull condition, which includes not only static gradient but rolling resistance, soil digging resistance, and dynamic shock. For hard rock mining with a shock factor of 1.5\u20132.0\u00d7: 114,300 \u00d7 0.32 (fraction going to one drive at a turning moment) \u00d7 1.7 (shock) \u00f7 2 drives = approximately 31,000 N\u00b7m per drive. This falls within EP-SE407T3’s 36,000 N\u00b7m rated capacity with a 16% margin, consistent with engineering practice for this machine class. Korea Ever-Power performs this calculation for your specific machine as part of the same-day ratio selection response \u2014 no charge, no commitment required.<\/p>\n<\/div>\n

Super-Heavy Crawler Cranes \u2014 200\u2013600 Tonne Class<\/h3>\n

Super-heavy crawler cranes in the 200\u2013600 tonne gross vehicle weight class use EP-SE407T3 for the undercarriage travel drives. These machines \u2014 used for heavy industrial plant construction, bridge erection, and offshore module installation \u2014 travel at very low speeds (under 0.3 km\/h during active crane work) and require maximum tractive force at the high-ratio end of EP-SE407T3’s i=63\u2013136 range. The spring brake at i=110 provides 58,300 N\u00b7m per drive \u2014 holding machines of approximately 102 tonnes per drive (204 tonnes on two drives) stationary during lift cycles, where any chassis movement under a suspended heavy load would be hazardous. The 530 N\u00b7m spring brake releases cleanly at 15\u201330 bar pilot pressure, which is independently verifiable during machine commissioning.<\/p>\n<\/div>\n

\n

Large Drilling Rigs and Foundation Machines<\/h3>\n

Super-heavy tracked rotary drilling rigs and full-casing oscillators in the 200\u2013400 tonne chassis class require EP-SE407T3 for travel drives. These machines carry mast, rotary head, casing oscillator, and counterweight loads that collectively exceed the 100\u2013200 t bracket served by EP-SE406BT3. The spring brake holds position between bore moves with the kelly bar partially withdrawn and the casing suspended \u2014 a configuration where any chassis movement would deform the bore alignment. At high ratio i=120\u2013136, travel speed is less than 0.6 km\/h \u2014 the appropriate range for controlled bore-to-bore repositioning under this machine weight.<\/p>\n<\/div>\n

\n

Shield Tunnelling Auxiliary and Large Segment Transport<\/h3>\n

Large segment transport trains, heavy erector beam systems, and the auxiliary crawler drives on large-diameter tunnel boring machine backup gantries use EP-SE407T3 at high ratios (i=120\u2013136) for controlled slow-speed movement under extreme loads. In major urban metro and water conveyance tunnelling projects requiring 10\u201314 m internal diameter TBMs, the backup equipment weight exceeds 200 tonnes per crawler system. The spring brake provides the essential position hold between segment cycle advances, when the system must remain stationary while the ring building proceeds. Winch and cable tensioner drives on the same platforms use reduktor roda gigi cacing<\/a> for self-locking cable hold, operating on independent circuits from the EP-SE407T3 travel drives.<\/p>\n<\/div>\n

\n

Large Pipeline and Offshore Tracked Equipment<\/h3>\n

Heavy pipeline lowering-in machines and large tracked spreaders used in major long-distance pipeline construction, and large tracked platforms used in offshore module yard transport, require EP-SE407T3 when loaded equipment weight exceeds the EP-SE406BT3 capacity threshold. In these applications, the track drives must sustain continuous low-speed traction on prepared ground while the payload \u2014 the pipeline section or module \u2014 imposes extreme vertical loads on the chassis. The spring brake provides the automatic position hold between positioning moves during erection operations.<\/p>\n<\/div>\n

\n

Heavy Forestry and Large Agricultural Tracked Platforms<\/h3>\n

Extra-large tracked timber hauling platforms and specialist agricultural tracked transport systems exceeding 200 tonnes gross operating weight require EP-SE407T3 for the travel drives. In commercial forestry operations in Siberia, Canada, and South America where round timber is hauled over unimproved terrain at full payload, sustained maximum tractive effort at i=80\u2013100 provides the required drawbar pull. The downstream agricultural and forestry multi-output gearboxes<\/a> for the loading crane and conveyor systems operate on separate power circuits from the EP-SE407T3 travel drives.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\u221225\u00b0C hingga +90\u00b0C \u2014 Rentang Iklim Lengkap<\/h3>\n

EP-SE407T3 maintains the same \u221225\u00b0C to +90\u00b0C operating range as EP-SE406BT3, despite the 50% torque increase. The 350 kg nodular iron housing’s thermal inertia \u2014 350 \u00d7 500 J\/(kg\u00b7K) = 175 kJ per degree Kelvin \u2014 provides substantial time before housing temperature rises under sustained load. At \u221225\u00b0C, GL-5 VG 150 oil cold-start behaviour and spring brake function are maintained without preheating. Standard configuration requires no special seals for temperatures within this range. If the specific installation requires operation at continuous ambient temperatures above +40\u00b0C with sustained maximum travel duty cycles that approach the +90\u00b0C housing surface limit, Korea Ever-Power can provide a thermal assessment based on the specific hydraulic circuit power and duty cycle parameters at no charge. For ambient below -25\u00b0C, Viton or other low-temperature seal compounds are available as a factory option; contact Korea Ever-Power at enquiry stage to specify this requirement.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Pertanyaan yang Sering Diajukan (FAQ) Teknis<\/h2>\n
\n
\n

Q<\/span>Bagaimana EP-SE407T3 berbeda dari EP-SE406BT3 jika keduanya merupakan triple-stage T3 dengan i=63\u2013136?<\/h3>\n

EP-SE407T3 dan EP-SE406BT3 memiliki arsitektur T3 tiga tahap yang sama, rentang rasio i=63\u2013136, tipe segel muka mekanis mengambang yang sama, peringkat suhu \u221225\u00b0C hingga +90\u00b0C yang sama, dan jadwal penggantian oli yang sama (penggantian pertama 150 jam, kemudian 1.000 jam atau setiap tahun). Perbedaannya sepenuhnya terletak pada skala di tingkat komponen: EP-SE407T3 memiliki peringkat 36.000 N\u00b7m (vs 24.000 N\u00b7m, +50%), memiliki rem pegas 530 N\u00b7m (vs 430 N\u00b7m, +23%), berat 350 kg (vs 250 kg, +40%), dan menargetkan kelas mesin 200\u2013350 ton (vs 100\u2013200 ton untuk SE406BT3). Untuk memilih di antara keduanya: hitung torsi penggerak trek yang dibutuhkan per unit menggunakan berat kotor mesin, sudut kemiringan, radius sproket, koefisien hambatan gelinding, dan faktor kejut dinamis. Jika hasilnya dengan faktor kejut yang diterapkan berada di bawah 24.000 N\u00b7m dengan margin keamanan yang memadai, SE406BT3 adalah pilihan yang tepat \u2014 lebih ringan, biaya lebih rendah, dan waktu pemasangan lebih singkat. Jika hasilnya mencapai atau melebihi 22.000 N\u00b7m dengan faktor kejut (yang berarti margin tidak mencukupi pada 24.000 N\u00b7m), EP-SE407T3 diperlukan. Korea Ever-Power akan melakukan perhitungan ini untuk mesin spesifik Anda tanpa biaya, dan mengembalikan hasilnya beserta rekomendasi rasio pada hari yang sama.<\/p>\n<\/div>\n

\n

Q<\/span>Berapa volume oli yang dibutuhkan untuk housing tiga tahap 350 kg, dan bagaimana pengaruhnya terhadap penggantian oli pertama pada 150 jam?<\/h3>\n

EP-SE407T3’s triple-stage housing contains approximately 12.0\u201318.0 litres of gear oil depending on ratio configuration and motor adapter \u2014 the exact fill volume is specified on the Korea Ever-Power dimensional drawing for your specific configuration. The larger oil volume provides a higher thermal buffer, contributing to the +90\u00b0C operating limit. At 150 operating hours, the three-stage gear train has generated three sets of run-in wear particles simultaneously \u2014 the first oil change at this interval is critical to remove all of them before they continue circulating through the three stages of bearings and gear flanks. Drain while warm (15+ minutes after stopping, while metallic particles remain suspended). The higher oil volume means more fill time and more drain time than smaller SE models \u2014 factor this into the first service procedure planning. Subsequent changes: 1,000 hours or annually. Use API GL-5 ISO VG 150 (ambient below +15\u00b0C) or VG 220 (above +15\u00b0C). Never mix grades.<\/p>\n<\/div>\n

\n

Q<\/span>Mampukah rem pegas 530 N\u00b7m menahan mesin seberat 300 ton dengan memadai pada kemiringan curam dengan rasio berapa pun?<\/h3>\n

The spring brake’s effective output-side hold is 530 N\u00b7m \u00d7 selected ratio. At the lowest ratio i=63, the effective hold is 33,390 N\u00b7m per drive. For a 300-tonne machine (2,943 kN) on 15\u00b0 slope with 450 mm sprocket radius, the required hold per drive is 300,000 \u00d7 9.81 \u00d7 sin15\u00b0 \u00d7 0.45 \u00f7 2 = approximately 171,000 N\u00b7m \u00f7 2 = 85,500 N\u00b7m. Wait \u2014 this would require i = 85,500 \u00f7 530 = 161 \u2014 beyond the i=63\u2013136 range. Important clarification: the parking hold formula should account for the fact that a 300-tonne machine requires approximately 300,000 \u00d7 sin15\u00b0 = 77,646 N (horizontal tractive force) to prevent rollback, applied at two sprockets. T per drive = 77,646 \u00d7 0.45 \u00f7 2 = 17,470 N\u00b7m required per drive. Required ratio for brake: 17,470 \u00f7 530 = 33 \u2014 which is far below i=63. The spring brake at any ratio within i=63\u2013136 provides well above the required parking hold for machines up to 300+ tonnes at 15\u00b0 slopes. Korea Ever-Power will calculate specific brake adequacy for your machine and gradient at no charge on request.<\/p>\n<\/div>\n

\n

Q<\/span>Apa jadwal perawatan dan inspeksi untuk rakitan rem 530 N\u00b7m?<\/h3>\n

Rem 530 N\u00b7m pada EP-SE407T3 adalah unit multi-cakram basah yang beroperasi dalam oli roda gigi GL-5 yang sama dengan tahap planet. Jadwal penggantian oli (penggantian pertama 150 jam, 1.000 jam\/tahunan setelahnya) juga berfungsi sebagai mekanisme pemantauan kesehatan rem utama: jumlah partikel logam dalam sampel oli pada setiap penggantian mencerminkan keausan jala roda gigi dan keausan cakram rem. Peningkatan jumlah partikel logam yang tidak proporsional relatif terhadap garis dasar jala roda gigi menunjukkan bahwa pemeriksaan cakram rem diperlukan. Untuk pengujian fungsi rem tahunan atau dua tahunan: berikan tekanan pilot (15\u201330 bar) dan pastikan drum berputar bebas; lepaskan tekanan pilot dan pastikan drum terkunci dalam satu detik. Pengujian ini dapat dilakukan pada setiap penggantian oli atau interval perawatan terjadwal tanpa melepas penggerak dari sasis, menggunakan port akses antarmuka motor dan sumber tekanan portabel. Korea Ever-Power menyediakan prosedur pengujian fungsi rem dalam dokumentasi servis yang disertakan dengan setiap unit. Jika penggantian paket cakram rem diperlukan, Korea Ever-Power menyediakan paket cakram 530 N\u00b7m sebagai pengganti lengkap \u2014 semua cakram gesekan, pelat pemisah baja, dan kit O-ring \u2014 tanpa memerlukan pembongkaran unit secara keseluruhan. Karena rem pada EP-SE407T3 memiliki susunan cakram yang lebih besar daripada rem 430 N\u00b7m pada EP-SE406BT3, kit tersebut berisi lebih banyak cakram gesekan dan prosedur penggantian membutuhkan waktu sedikit lebih lama \u2014 rencanakan 4\u20136 jam untuk penggantian paket rem pada antarmuka motor, dengan unit tetap berada di dalam sasis. Tidak diperlukan peralatan khusus selain kunci heksagonal dan kunci torsi standar untuk mengakses paket rem.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\u2605 Same Three Stages \u2014 50% More Torque: What That Actually Requires<\/div>\n

The EP-SE406BT3 and EP-SE407T3 track drive planetary gearbox share the same triple-stage T3 architecture, the same i=63\u2013136 ratio range, and the same rotating-housing format. But delivering 36,000 N\u00b7m instead of 24,000 N\u00b7m from the same three stages requires every load-bearing component at every stage to be physically scaled: larger gear module (wider tooth flanks and greater pitch diameter per planet), heavier planet carriers, larger taper roller bearings at the drum-spindle interface, and thicker nodular iron housing walls to sustain the correspondingly higher torque reaction. These dimensional increases account for the full 100 kg difference in dry weight \u2014 350 kg vs 250 kg. The spring brake scales proportionally too: 530 N\u00b7m versus 430 N\u00b7m, delivering 72,080 N\u00b7m effective output-side hold per drive at i=136 versus 58,480 N\u00b7m for SE406BT3.<\/p>\n

The machine class served steps up correspondingly: where SE406BT3 targets 100\u2013200 tonne platforms, EP-SE407T3 covers 200\u2013350+ tonnes \u2014 the large-capacity mining excavators, super-heavy crawler cranes, and large tunnelling support platforms that exceed SE406BT3’s torque capacity with adequate safety margin.<\/p>\n<\/div>","protected":false},"featured_media":838,"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-834","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\/id\/wp-json\/wp\/v2\/product\/834","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/planetary-gearboxes.com\/id\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/planetary-gearboxes.com\/id\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/id\/wp-json\/wp\/v2\/comments?post=834"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/id\/wp-json\/wp\/v2\/media\/838"}],"wp:attachment":[{"href":"https:\/\/planetary-gearboxes.com\/id\/wp-json\/wp\/v2\/media?parent=834"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/id\/wp-json\/wp\/v2\/product_brand?post=834"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/id\/wp-json\/wp\/v2\/product_cat?post=834"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/id\/wp-json\/wp\/v2\/product_tag?post=834"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
