EP-CTD3500 Planetary Track Drive Gearbox ?? 35,000 Nm
Brevini CTD3500 Compatible Replacement | EVER POWER
Он EP-CTD3500 is EVER POWER’s high-performance planetary track drive gearbox for large tracked equipment, delivering 35 000 Нм 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.

Обзор продукта
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.

Принцип работы

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.
The optional 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.
Основные преимущества
|
★ Up to 200:1 Single Unit
4-stage achieves 200:1 without tandem gearbox ?? saves weight, space and maintenance points. |
★ Condition Monitoring Ready
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. |
Технология конструкций и материалов
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.
Типичные сценарии применения
| Промышленность | Машина / Использование | Ключевое требование |
|---|---|---|
| Горнодобывающая промышленность | 55 t excavator, hard rock mine | 3.0x overload handles buried rock impacts; condition monitoring tracks gearbox health 24/7. |
| Трубопровод | Heavy crawler pipelayer, large diameter line | High torque at very slow speed during precision pipe lowering operations. |
| Оффшор | Jack-up rig leg drive | 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. |

| Австралия | 55 t excavator, magnetite iron ore mine, 6 units | “Hard magnetite generates extreme shock loads. The 3.0x overload rating has eliminated the tooth failures we previously experienced every 4,000 hours.” ?? Equipment Director, Pilbara. |
| Norway | Offshore jack-up rig leg drive, North Sea | “C5M coating and IP68 sealing held up perfectly after 2 winter seasons in the North Sea. Condition monitoring data flagged a bearing trend 4 weeks before failure ?? avoided a costly rig downtime.” ?? Rig Engineer, Stavanger. |
| China | Heavy tracked transfer car, large steel mill | “200:1 ratio lets us use a compact motor on a 200-tonne steel slab carrier. Energy saving per coil transferred is measurable.” ?? Plant Engineer, Wuhan. |
Часто задаваемые вопросы
Q: Can condition monitoring data be integrated with our existing Modbus SCADA?
A: Yes. The PT100 probe and vibration accelerometer connect to standard signal conditioners compatible with Modbus RTU, PROFIBUS or 4-20 mA analogue.
Q: Is DNV or BV certification available for offshore installations?
A: Yes. Third-party witness inspection by DNV GL or Bureau Veritas can be arranged. Specify at order.
Q: What is the maximum recommended oil change interval?
A: With PAO VG 460, first change at 500 hours, then every 3,000 hours or 18 months. With VG 320, every 2,500 hours or 12 months.
