EP-CTD2051 Planetary Track Drive Gearbox ?? 20,510 Nm
Brevini CTD2051 Compatible Replacement | EVER POWER
그만큼 EP-CTD2051 bridges the gap between compact and mid-size tracked equipment, delivering 20,510 Nm output torque with a 2-to-3-stage configurable planetary design. As a direct replacement for the Brevini riduttori CTD2051, this unit is widely used in 5-10 t class excavators, tracked scissor lift bases and light utility crawler vehicles where mounting space is tight but torque requirements exceed mini-class units.
제품 개요
The EP-CTD2051 targets 5-10 t tracked construction equipment, scissor lift and aerial work platform (AWP) crawler bases, tracked compact carriers and utility track vehicles. Its configurable stage count ?? 2-stage for faster travel speed, 3-stage for maximum pulling torque ?? is managed by swapping a single internal stage module at the factory, keeping the external housing and flange pattern unchanged.

작동 원리
The configurable design operates by selecting either a 2-stage or 3-stage planet train module installed inside the same housing shell. In 2-stage mode the unit delivers maximum travel speed ?? suited to AWP bases that traverse job sites quickly between lifts. In 3-stage mode the same housing delivers maximum tractive effort for pushing through soft ground or climbing steep ramps.
그만큼 floating sun gear in both configurations self-centres the load across all planets, compensating for minor motor shaft run-out and extending planet bearing life in high-cycle AWP applications where the travel motor starts and stops hundreds of times per shift.
핵심 이점
|
◆ 2/3-Stage Configurable
Same housing serves two ratio ranges ?? reduces OEM inventory from two part numbers to one. |
◆ Floating Sun Gear
Self-equalises planet loading, extending bearing life in high-start-stop AWP duty cycles. |
|
◆ Compact 42 kg Body
Fits 5-10 t class machine track frames without structural modification. |
◆ IP67 All-Terrain Sealing
Handles mud, fine dust and pressure wash common on construction sites and rental fleets. |
|
◆ Direct CTD2051 Replacement
Identical flange and brake port layout ?? bolt-in, no adaptation required. |
구조 및 재료 기술
The housing is pressure-die-cast from GGG50 연성 주철 and finish-machined to H7 bore tolerance. Planet gears use 17CrNiMo6 표면 경화강 carburised to 0.8-1.1 mm case depth and ground to DIN 5 accuracy. The brake disc stack uses sintered metal friction discs rated for 80,000 engagement cycles ?? important for AWP applications where the parking brake is engaged and released multiple times per hour.
일반적인 적용 시나리오
| 산업 | Machine / Use | Key Requirement |
|---|---|---|
| AWP / Lifting | Tracked scissor lift base (8-12 m) | 3-stage for ramp climbing; 2-stage for yard tramming between lifts. |
| 건설 | 6-8 t compact excavator | Wide ratio range covers both trench digging (high torque) and road travel (higher speed). |
| Utility | Tracked compact carrier / dumper | IP67 handles quarry dust and water crossings common in utility groundworks. |
| Maintenance | Pipeline inspection crawler | Slow precise positioning in confined trenches; spring brake holds on inclined pipe sections. |
선택 가이드
- 스테이지 카운트 ?? 2-stage for max speed; 3-stage for max tractive effort. State required ratio.
- Machine Weight (t) ?? Confirm drawbar pull requirement for worst-case gradient.
- Duty Cycle ?? AWP high-start-stop vs continuous excavator travel affects brake specification.
- Motor Flange ?? SAE-B 2-bolt or 4-bolt; shaft diameter and keyway specification.
- Rental Fleet Requirement ?? Rental fleets benefit from seal kit pre-packing; specify at order.

Case Studies ?? Engineer Field Notes
| 국가 | 애플리케이션 | 고객 피드백 |
|---|---|---|
| 영국 | Tracked scissor lift fleet renewal, 18 units | “We needed a unit that could handle the repeated brake cycling of a rental AWP. After 12 months and 200,000+ brake engagements across the fleet, not a single brake failure.” ?? Fleet Engineer, Midlands rental company. |
| 대한민국 | 7 t compact excavator OEM supply, 30 units/month | “The 2/3-stage flexibility let us rationalise from two Brevini part numbers to one EVER POWER number. Procurement is much simpler now.” ?? Purchasing Manager, Busan OEM. |
| Poland | Pipeline inspection crawler for gas network maintenance | “Slow-speed precision in narrow trenches is critical. The floating sun gear eliminated the vibration we had with the previous supplier.” ?? Field Engineer, Warsaw. |
자주 묻는 질문
Q: Can I change stage count after installation?
A: Stage count is set at the factory. It cannot be changed in the field. Please specify required ratio at order.
Q: What brake release pressure is required?
A: Standard spring brake releases at 20-30 bar hydraulic pressure. Specify if your machine circuit pressure differs.
Q: Is a seal kit included with each unit?
A: A standard seal kit is optionally included. Specify at order; recommended for rental fleet purchases.
