EP-CTD3200 Planetary Track Drive Gearbox ?? 32,000 Nm
Brevini CTD3200 Compatible Replacement | EVER POWER
De EP-CTD3200 is EVER POWER’s high-cycle workhorse for 20-30 t tracked equipment, delivering 32,000 Nm output torque with a 4-planet output carrier that extends gear tooth life by approximately 25% versus a conventional 3-planet design. Engineered as a form-and-function replacement for the Brevini riduttori CTD3200, this unit is specified by maintenance teams who prioritise longer service intervals over minimum purchase price.
Productoverzicht
The EP-CTD3200 targets 25-30 t hydraulic excavators, large tracked stabilisers, crawler-type demolition machines and heavy tracked road-building equipment. The 4-planet output carrier is the key differentiator ?? four simultaneous tooth contacts share the output torque equally, reducing per-tooth stress and making this unit measurably more suited to continuous duty cycles than the 3-planet alternatives it replaces.

Werkingsprincipe
The 3-stage arrangement uses standard 3-planet modules in stages 1 and 2, optimised for high input speed tolerance. The third stage upgrades to a 4-planet carrier. Mathematically, distributing output torque across four planets instead of three reduces the load at each tooth contact by 25% at equivalent torque. This improvement either extends tooth fatigue life by the same proportion at rated torque, or increases the momentary overload tolerance to 2.8x rated torque ?? critical for excavators striking buried rock or concrete during trench digging.
Kernvoordelen
|
► 4-Planet Output Stage
~25% lower per-tooth stress ?? quantifiably longer service intervals on high-hour machines. |
► 2.8x Overload Tolerance
Buried rock strikes and concrete encounters are absorbed without tooth damage. |
|
► 28:1 – 140:1 Wide Ratio
Covers fast tramming and maximum digging torque requirements from one product. |
► IP68 Sealed
Factory-tested submersion sealing for flooded excavation and stream-crossing duty. |
|
► Direct CTD3200 Drop-In
Identical flange, spline and brake port layout ?? zero adaptation at installation. |
Structuur- en materiaaltechnologie
Output stage planet gears are forged from 17CrNiMo6 vacuum-degassed steel for superior core toughness. Carburising depth is maintained at 0.9-1.2 mm; tooth profiles are ground to ISO accuracy grade 5. Each planet journal runs on a needle roller bearing assembly with a hardened shaft, achieving higher radial stiffness than bush bearings at the same pin diameter. The housing flange face is finish-turned to 0.015 mm flatness to ensure correct brake disc stack geometry without shimming.
Typische toepassingsscenario's
| Industrie | Machine / Use | Key Requirement |
|---|---|---|
| Earthmoving | 28 t excavator, mixed rock/clay site | Buried rock impacts at 2.8x rated torque ?? absorbed without tooth failure. |
| Road Building | Large tracked soil stabiliser | Continuous slow-speed operation over long shifts ?? 4-planet stage extends overhaul life. |
| Demolition | 25 t tracked shear carrier | High shock loads from steel shear cutting; overload tolerance prevents repeated failures. |
| Recycling | Heavy tracked trommel screen drive | Continuous 24/7 operation ?? extended service interval reduces planned downtime. |
Selectiegids
- Operating Hours per Year ?? Machines running 6,000+ hours/year benefit most from the 4-planet extended life.
- Soil/Rock Conditions ?? Mixed or hard-rock sites require the 2.8x overload capacity; specify accordingly.
- Ratio ?? 28:1 for fast large machines; 140:1 for slow-speed high-torque applications.
- Oil Grade ?? VG 220 for standard duty; VG 320 for high-temperature continuous operation.
- Motor Shaft ?? Provide motor specification (cc/rev, flange, shaft) for direct ratio confirmation.

Case Studies ?? Engineer Field Notes
| Land | Sollicitatie | Klantenfeedback |
|---|---|---|
| Canada | 28 t excavator fleet, oil sands site, 10 units | “Hard frozen ground in winter generates brutal shock loads. The 4-planet output has reduced our gearbox failure rate from 3 per year to zero over 18 months.” ?? Equipment Manager, Fort McMurray. |
| Germany | Large tracked soil stabiliser, highway base layer project | “Continuous 10-hour shift operation. The 4-planet stage maintained the same oil temperature as our previous 3-planet unit but with 8% less wear on the planet journals at the 1,000-hour inspection.” ?? Technical Manager, Stuttgart. |
| VAE | 25 t demolition shear carrier, Dubai infrastructure | “40 degC ambient heat is a stress test for any gearbox. VG 320 oil and IP68 sealing kept this unit running without issues through a full 8-month project.” ?? Site Engineer, Dubai. |
Veelgestelde vragen
V: Wat is het minimale interval voor het verversen van de olie?
A: With synthetic VG 220 or VG 320, first change at 500 hours, then every 2,500 hours or 12 months, whichever comes first.
Q: Does the 4-planet carrier require special tooling for maintenance?
A: No. Planet pin removal uses standard press tooling. The 4-planet carrier has no additional complexity versus a 3-planet unit for qualified service technicians.
V: Welke documentatie wordt bij elk apparaat meegeleverd?
A: Installation/maintenance manual, dimensional drawing, hydrostatic test certificate and CE declaration. Material certs (3.1) available on request.
