EP-CTD3500 Planetary Track Drive Gearbox ?? 35,000 Nm<\/h1>\n

Brevini CTD3500 Compatible Replacement | EVER POWER<\/p>\n

The EP-CTD3500<\/strong> is EVER POWER’s high-performance planetary track drive gearbox for large tracked equipment, delivering 35,000 Nm<\/strong> output torque from a 3-to-4-stage architecture with a maximum ratio of 200:1<\/strong>. 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.<\/p>\n

\"EP-CTD3500<\/p>\n

Product Overview<\/h2>\n

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<\/strong>. The 4-stage configuration allows the EP-CTD3500 to reach 200:1<\/strong> ratio from a single compact housing ?? eliminating the need for tandem gearbox installations common on very high-ratio applications. Optional condition monitoring sensor ports<\/strong> allow connection to machine telematics for real-time gear oil temperature and vibration trending.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

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<\/strong> ?? 30% longer tooth face than the standard width ?? increases the continuous power capacity of the output stage without requiring a larger housing.<\/p>\n

The optional condition monitoring suite<\/strong> 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.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
★ Up to 200:1 Single Unit<\/strong>
4-stage achieves 200:1 without tandem gearbox ?? saves weight, space and maintenance points.<\/div>\n<\/td>\n
\n
★ Condition Monitoring Ready<\/strong>
Oil temperature and vibration sensor ports enable predictive maintenance integration.<\/div>\n<\/td>\n<\/tr>\n
\n
★ 3.0x Overload Capacity<\/strong>
Momentary overloads from buried obstacles are absorbed without catastrophic tooth failure.<\/div>\n<\/td>\n
\n
★ -35 degC Arctic Rated<\/strong>
PAO VG 460 oil + low-temperature FKM seals standard for northern climate operations.<\/div>\n<\/td>\n<\/tr>\n
\n
★ C5M Marine Epoxy Coating<\/strong>
720-hour salt spray rating. Suitable for offshore and coastal applications.<\/div>\n<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

The housing exterior carries a C5M marine epoxy coating system<\/strong> (primer + intermediate + topcoat, total DFT >= 250 microns, 720-hour salt spray). Gear steels are 18CrNiMo7-6 vacuum-arc-remelted (VAR)<\/strong> ?? 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<\/strong> for corrosion resistance in offshore and coastal environments.<\/p>\n
