EP-CTD3500 Planetary Track Drive Gearbox ?? 35,000 Nm
Brevini CTD3500 Compatible Replacement | EVER POWER
O EP-CTD3500 is EVER POWER’s high-performance planetary track drive gearbox for large tracked equipment, delivering 35.000 Nm output torque from a 3-to-4-stage architecture with a maximum ratio of 200:1. Engineered to replace the Brevini riduttori CTD3500, this unit is specified by OEMs and maintenance teams operating 40-60 t class machines where every hour of unplanned downtime has a direct impact on project profitability.

Visão geral do produto
Served equipment types: 50 t+ hydraulic excavators, large tracked bulldozers, heavy pipeline crawler carriers, large offshore jack-up leg drives and extreme-duty tracked transfer platforms. The 4-stage configuration allows the EP-CTD3500 to reach 200:1 ratio from a single compact housing ?? eliminating the need for tandem gearbox installations common on very high-ratio applications. Optional condition monitoring sensor ports allow connection to machine telematics for real-time gear oil temperature and vibration trending.

Princípio de funcionamento

In 3-stage mode, the unit covers 35:1-100:1. Switching to 4-stage adds a final wide-face planet stage that extends the ratio to 200:1 within the same housing diameter. The wide-face planet gear ?? 30% longer tooth face than the standard width ?? increases the continuous power capacity of the output stage without requiring a larger housing.
O opcional condition monitoring suite uses a PT100 temperature probe in the oil sump and an M8-threaded vibration sensor mounting pad on the housing. Data can be streamed to any major PLC or SCADA platform via 4-20 mA or Modbus RTU.
Principais vantagens
|
★ Up to 200:1 Single Unit
4-stage achieves 200:1 without tandem gearbox ?? saves weight, space and maintenance points. |
★ Pronto para monitoramento de condições
Oil temperature and vibration sensor ports enable predictive maintenance integration. |
|
★ 3.0x Overload Capacity
Momentary overloads from buried obstacles are absorbed without catastrophic tooth failure. |
★ -35 degC Arctic Rated
PAO VG 460 oil + low-temperature FKM seals standard for northern climate operations. |
|
★ C5M Marine Epoxy Coating
720-hour salt spray rating. Suitable for offshore and coastal applications. |
Tecnologia de Estrutura e Materiais
The housing exterior carries a C5M marine epoxy coating system (primer + intermediate + topcoat, total DFT >= 250 microns, 720-hour salt spray). Gear steels are 18CrNiMo7-6 vacuum-arc-remelted (VAR) ?? aircraft turbine-grade material ?? carburised to 1.0-1.4 mm and ground to DIN ISO 1328 accuracy class 5. Wide-face planet gear blanks are individually balanced after machining. All external fasteners are stainless A4-80 grade for corrosion resistance in offshore and coastal environments.
Cenários típicos de aplicação
| Indústria | Máquina / Uso | Requisito fundamental |
|---|---|---|
| Mineração | 55 t excavator, hard rock mine | 3.0x overload handles buried rock impacts; condition monitoring tracks gearbox health 24/7. |
| Gasoduto | Heavy crawler pipelayer, large diameter line | High torque at very slow speed during precision pipe lowering operations. |
| Em alto-mar | Sistema de acionamento das pernas da plataforma autoelevatória | C5M coating and IP68 sealing withstand continuous salt water spray and immersion. |
| Transfer | Industrial tracked transfer car, steel mill | 200:1 ratio provides ultra-slow controlled load movement; spring brake holds on inclines. |
