613L3 \u2014 45,000 Nm at 108:1
\nNothing to choose. Everything optimised.<\/span><\/h2>\n

The EP-613L3 eliminates every decision except the brake size. There is one ratio, one stage count, one housing, and one set of internal gears \u2014 because at 45,000 Nm, the machines are expensive enough and the duty severe enough that the gearbox should be an absolute certainty, not a variable. Every 613L3 that leaves the factory is mechanically identical to every other 613L3. Every oil analysis data point, every vibration baseline, and every field performance record from any 613L3 anywhere in the world is directly comparable to yours.<\/p>\n<\/div>\n

The EP-613L3 sits between the 611 (36,000 Nm, ratios 41-47) and the flagship 615L3 (60,000 Nm) in the planetarisk hjuldrev gearkasse<\/a> range. Where the 611 serves machines that need moderate-speed travel, the 613L3 at ratio 108 is purpose-built for low-speed, maximum-traction applications where the machine never exceeds 8 km\/h \u2014 and usually operates below 4. These are the mining haul trucks on the steepest pit ramps, the SPMTs carrying reactor vessels, and the TBM segment erectors rotating 12-tonne concrete rings into position underground.<\/p>\n<\/section>\n

Multi-Disc Brake \u2014 Why the 613L3 Uses a Different Braking Architecture<\/h2>\n
\n
\n

Every wheel drive below the 613 uses a single friction disc pressed against a reaction plate by springs and released by hydraulic pressure. This design is compact and adequate for braking torques up to approximately 600 Nm. At 800 Nm \u2014 the maximum the 613 offers \u2014 a single disc would require either a very large disc diameter (which would not fit inside the housing) or very high spring preload (which would demand excessive hydraulic release pressure). The multi-disc brake solves both problems.<\/p>\n

Instead of one large friction disc, the 613L3 stacks multiple thinner discs alternating with steel separator plates. The total friction surface area is the sum of all disc faces, which means the same braking torque can be achieved at lower contact pressure per disc \u2014 extending the disc life and reducing the spring force needed. The result is an 800 Nm brake that fits inside the same housing envelope, releases at a practical hydraulic pressure (25-35 bar), and offers a disc life 2-3 times longer than a single-disc design at the same torque rating.<\/p>\n

\n

Why One Ratio Is the Correct Engineering Decision at 45,000 Nm<\/h2>\n

Offering multiple ratios at this torque class would create the illusion of flexibility while delivering no real engineering value. Here is why.<\/p>\n

\n
\n

The machines are purpose-built<\/strong><\/p>\n

At 45,000 Nm, every vehicle is a custom-designed machine \u2014 a specific mining truck model, a specific SPMT configuration, a specific TBM design. None of these machines can accept a gearbox with “the wrong ratio” because the entire hydraulic circuit, motor selection, pump sizing, and vehicle performance specification are locked to one operating point before the gearbox is ordered. A choice of ratios would not help \u2014 it would only create the possibility of ordering the wrong one.<\/p>\n<\/div>\n

\n

Fleet interchangeability is maximised<\/strong><\/p>\n

With one ratio, every 613L3 in any stockroom anywhere in the world is a direct replacement for any other 613L3. There is no risk of installing a ratio 75 unit where a ratio 108 was specified, no need to verify ratio markings during an emergency midnight replacement, and no possibility of mixing ratios across axles on the same vehicle. One part number, one performance specification, zero ambiguity.<\/p>\n<\/div>\n

\n

Manufacturing consistency is absolute<\/strong><\/p>\n

Every 613L3 uses identical gears, bearings, and housing castings. The factory produces one gear set configuration, verifies one contact pattern, sets one bearing preload, and runs one dynamometer test programme. This eliminates the manufacturing variability that arises when a production line switches between multiple gear sets \u2014 variability that can produce unit-to-unit differences in noise, efficiency, and wear rates within the same model range.<\/p>\n<\/div>\n

\n

Field data is directly poolable<\/strong><\/p>\n

Oil analysis results, vibration baselines, and failure mode data from every 613L3 in every application worldwide feed into a single statistical population. When a mining fleet in Chile reports a specific iron particle trend at 8,000 hours, a fleet in Zambia running the same model can use that data directly for predictive maintenance scheduling \u2014 because the gearboxes are identical, not just similar. Contact Koreas evige magt<\/a> for fleet-level reliability data sharing arrangements.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

45,000 Nm Wheel Drive \u2014 The Machines That Define Extreme Traction<\/h2>\n

\"Ultra-heavy<\/p>\n

\n
\n

Mining Haul Trucks (60-100 Tonne Payload)<\/h3>\n

Rigid-frame haul trucks climbing 20-25% loaded haul roads at 4-6 km\/h for hours at a time. The 613L3 at ratio 108 provides 45,000 Nm per wheel \u2014 and with six or eight driven wheels on these trucks, the total tractive effort reaches 270,000-360,000 N. The multi-disc 800 Nm brake delivers 86,400 Nm of holding torque per wheel, holding a 200-tonne GVW truck on any grade the tyres can physically grip. The planetarisk gearkasse med b\u00e6ltedrev<\/a> serves the ancillary crawler equipment in the same pit.<\/p>\n<\/div>\n

\n

Heavy SPMTs (200-600 Tonne Loads)<\/h3>\n

Self-propelled modular transporters carrying refinery columns, bridge girders, and offshore platform modules at walking pace. Where the 607L3 at ratio 108 carries lighter loads (17,000 Nm per wheel), the 613L3 at the same ratio steps up to 45,000 Nm \u2014 serving the heavier trailer configurations with 200-600 tonne payloads where individual wheel loads are proportionally higher. The 108:1 ratio provides the sub-1 km\/h creep speed and millimetre-level position control these heavy transport operations<\/a> demand.<\/p>\n<\/div>\n

\n

TBM Auxiliary Drives and Shield Movers<\/h3>\n

Tunnel boring machine segment erectors, gripper advance mechanisms, and backup system propulsion require high torque at very low speed inside confined, wet, high-temperature environments. The 613L3 provides 45,000 Nm in a sealed housing that resists the bentonite, groundwater, and abrasive dust present inside TBM shields. The 108:1 ratio gives the precise rotational control needed for positioning 12-tonne tunnel lining segments within the 2-3 mm tolerances that modern segmental linings require. The slewing drive gearbox<\/a> handles the erector arm rotation on the same TBM platform.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Planetary Wheel Drive Gearbox \u2014 45,000 Nm Single-Ratio FAQ<\/h2>\n
\n
\n

What is the maximum ground speed the 613L3 can achieve?<\/h3>\n

At 3,000 rpm motor input, ratio 108, and 800 mm tyre radius: output speed = 27.8 rpm, ground speed = 27.8 x 2 x 3.14 x 0.8 x 60 \/ 1,000,000 = 8.4 km\/h. In practice, the typical operating speed for 613L3 applications is 2-6 km\/h. The machine crawls; it does not road. If the application requires travel speed above 10 km\/h, the 613L3 is not the right model \u2014 consider the 611 (ratios 41-47) or 610 (ratios 20-111) at lower torque with higher speed capability.<\/p>\n<\/div>\n

\n

How does the multi-disc brake differ from a single-disc design in maintenance?<\/h3>\n

The multi-disc stack distributes the friction load across multiple surfaces, so each disc wears more slowly than a single disc carrying the same total torque. Inspection interval: every 5,000 hours (same as single-disc models). Expected disc life: 15,000-25,000 hours versus 8,000-15,000 hours for a single-disc at equivalent torque. When replacement is needed, the entire disc stack is replaced as a set \u2014 do not mix new and worn discs, as the thickness variation will cause uneven clamping and premature failure of the new discs.<\/p>\n<\/div>\n

\n

What is the difference between the 613L3 (45,000 Nm) and the 607L3 (17,000 Nm) at the same ratio 108?<\/h3>\n

Both deliver ratio 108 through three planetary stages, but the 613L3 uses larger-module gears, wider face widths, and larger-diameter bearings to carry 2.65x the torque. The 613L3 weighs 385 kg versus 185 kg for the 607L3. The output flange and housing dimensions are completely different \u2014 they are not interchangeable. Choose based on the torque requirement: 607L3 for machines generating up to 17,000 Nm per wheel, 613L3 for 17,001-45,000 Nm per wheel.<\/p>\n<\/div>\n

\n

How is a 385 kg wheel drive handled during field replacement in a mine?<\/h3>\n

Mining service trucks equipped with 2-5 tonne hydraulic cranes are the standard tool. The 613L3 requires a minimum lifting capacity of 750 kg at the working radius (1.94x safety factor). On large haul trucks, the wheel is at ground level, so the crane lifts the 613L3 horizontally from the service truck bed and positions it against the mounting face. Two technicians guide the unit while the crane holds the weight. Typical replacement time: 3-5 hours including oil drain, disconnection, removal, installation, refill, and brake function verification.<\/p>\n<\/div>\n

\n

Can a planetary wheel drive at this torque class replace an electric wheel motor?<\/h3>\n

In diesel-hydraulic trucks, the 613L3 serves the same function as an electric wheel motor in diesel-electric trucks: it converts rotary input into low-speed, high-torque wheel rotation. The hydraulic version (613L3 + hydraulic motor) is mechanically simpler and lighter than an equivalent electric wheel motor assembly, but lacks the regenerative braking capability that electric motors provide. For trucks operating on long downhill grades where retarding energy can be recovered, the diesel-electric architecture has an efficiency advantage. For flat or mixed-gradient operations, the hydraulic wheel drive system<\/a> is typically lighter, less expensive, and simpler to maintain.<\/p>\n<\/div>\n

\n

What oil volume does the 613L3 require?<\/h3>\n

Approximately 8-10 litres depending on mounting angle. Use API GL-5 SAE 80W-90 for standard conditions. First change at 250 hours. Subsequent changes every 1,500 hours in mining. Oil sampling every 500 hours is mandatory at this torque class \u2014 not recommended, mandatory. A 613L3 failure during operation can halt a 200-tonne haul truck on a pit ramp, blocking the entire haul road until a crane and service crew can reach the vehicle. The cost of quarterly oil sampling is negligible compared to one hour of blocked haul-road downtime.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

32 units across a fleet of four 85-tonne haul trucks. The single-ratio approach was the deciding factor for our procurement team: one part number, one stock quantity, zero risk of mis-specification during emergency replacement. We maintain four spare 613L3 units at the mine site. When a unit needs replacement, the technician grabs any one of those four \u2014 no checking, no verifying, no calling the office. Oil analysis trending across all 32 units is pooled into one reliability model. After 6,000 hours on the oldest units, the data shows consistent iron particle counts below threshold.

72 units on SPMT trailer sets for petrochemical module transport. The 613L3 replaced the 607L3 on our heaviest trailer configurations where the 17,000 Nm per wheel was no longer sufficient for the 400-500 tonne loads our clients are now specifying. The 108:1 ratio is identical between the two models, which meant our hydraulic circuit design did not change \u2014 only the gearbox and its mounting frame. Creep speed positioning at 0.3 km\/h under a 450-tonne reactor vessel was smooth and controllable. The multi-disc brake is a visible improvement over the single-disc on the 607L3 \u2014 the release is cleaner and the engagement feels more progressive.<\/p>\n<\/div>\n

Segment erector drive on a 12 m diameter TBM for a metro tunnel project. The 613L3 handles the 11-tonne segment rotation smoothly within the tight clearances inside the TBM shield. The IP sealing has held up well in the wet, high-pressure environment. The 4-star rating is because the 385 kg weight made crane access inside the TBM shield challenging during initial installation \u2014 the clearance between the shield inner wall and the erector frame barely allowed the lifting sling to pass. For future TBM applications, a factory-supplied custom lifting yoke matched to common erector frame geometries would simplify the initial installation significantly.<\/p>\n<\/div>\n<\/div>\n<\/section>\n<\/div>","protected":false},"excerpt":{"rendered":"
