EP-CTD1020 Compact Planetary Travel Drive Gearbox
Brevini CTD1020 Compatible Replacement | EVER POWER
Der EP-CTD1020 is EVER POWER’s entry-level planetary travel drive gearbox, engineered as a precise drop-in replacement for the Brevini riduttori CTD1020. Delivering 10,200 Nm output torque from a lightweight, flange-mounted body, this unit keeps compact tracked carriers, micro-excavators and light industrial crawler systems running efficiently and economically.
Produktübersicht
The EP-CTD1020 serves compact construction, agricultural, robotic and light industrial crawler markets. Its 2-stage epicyclic design keeps the housing short and the weight low ?? ideal for OEMs designing tight-envelope track frames where every kilogram and millimetre counts.
Core highlights: 10,200 Nm rated output torque, 2-stage planetary reduction, integrated spring-applied failsafe brake, SAE-B motor flange, IP67 sealing, -20 degC to +80 degC operating range.

Working Principle
Input from the hydraulic travel motor spins the first-stage sun gear. Multiple planet gears orbit the sun and react against a fixed ring gear, multiplying torque at the first-stage planet carrier. That carrier feeds the second stage for a final cumulative reduction of up to 50:1. The integrated spring-applied, hydraulically released disc brake engages automatically on loss of hydraulic pressure, preventing roll-back on slopes.
Core Advantages
|
● Lightweight Compact Design
Aluminium option brings housing weight below 22 kg ?? ideal for battery-powered compact carriers. |
● IP67 All-Round Sealing
Withstands temporary immersion, high-pressure wash and muddy terrain without seal failure. |
|
● Failsafe Spring Brake
Spring-engaged brake holds position on slopes whenever hydraulic pressure is removed. |
● Wide Ratio Selection
16:1 to 50:1 range covers both slow-work and faster-travel speed requirements in one platform. |
|
● Direct CTD1020 Drop-In Fit
Matching flange pattern and spline spec ?? bolt-in replacement without machine modification. |
Structure and Material Technology
The housing is available in die-cast aluminium alloy (lightweight duty) or GGG40 ductile iron (heavy duty). Planet gears are cut from 20CrMnTi case-hardening steel, carburised to 0.6-0.9 mm and ground to DIN 6 accuracy. The output flange bearing is a four-point contact slewing ring rated for combined axial, radial and overturning loads from the track chain. All seals use NBR compound, standard for mineral and synthetic gear oils.
Typische Anwendungsszenarien
| Industry | Machine / Use | Key Requirement |
|---|---|---|
| Construction | Compact (1-3 t) mini-excavator | Low weight critical for transported machine; 2-stage gives correct digging torque. |
| Agriculture | Narrow-track vineyard tractor chassis | Short housing fits between track frame rails; IP67 handles mud and spray. |
| Robotics | Outdoor inspection crawler | Battery-powered; aluminium housing minimises current draw per metre travelled. |
| Industrial | Light AGV / factory floor crawler | Smooth slow-speed positioning; spring brake holds position on ramps. |
Selection Guide
- Machine Weight (kg) – Determines required drawbar pull and minimum output torque.
- Travel Speed (m/min) – Fixes the ratio given the motor displacement and sprocket diameter.
- Motor Interface – SAE-B 2-bolt or 4-bolt; confirm shaft diameter and keyway.
- Housing Material – Specify aluminium (weight priority) or ductile iron (heavy-duty).
- Battery or Engine Powered – Low-temperature start requirement affects oil and seal grade choice.

Case Studies ?? Engineer Field Notes
| Land | Application | Customer Feedback |
|---|---|---|
| Japan | Compact vineyard crawler, 1.8 t, aluminium housing | “The weight saving over the cast iron version was 6 kg per side ?? exactly what we needed to stay under the transport weight limit.” ?? Design Engineer, Nagano OEM. |
| Netherlands | Battery-powered inspection crawler for dike monitoring | “IP67 sealing survived a full immersion incident during a flood test. Gearbox was completely unaffected.” ?? R&D Manager, Delft. |
| Mexico | Mini-excavator rental fleet overhaul, 12 units | “Drop-in replacement with zero modification. All 12 installed in two days. Cost saving funded two additional units.” ?? Workshop Manager, Guadalajara. |
Frequently Asked Questions
Q: What is the maximum static brake holding torque?
A: The spring brake provides a minimum static holding torque of 1.4x the rated output torque, sufficient for 25 deg slope hold.
Q: Can the aluminium housing be used in abrasive environments?
A: We recommend the ductile iron housing for abrasive soil or rock environments. Aluminium is best suited for clean-environment robotic and agricultural applications.
Q: Do you stock spare seal kits?
A: Yes. Standard seal kits for every EP-CTD model are stocked for same-week dispatch.
