EP-CTU3500 Planetary Track Drive Gearbox – 35,000 Nm<\/h1>\n

Brevini CTU3500 Compatible Replacement | EVER POWER<\/strong><\/p>\n

The EP-CTU3500<\/strong> addresses the most demanding segment of the tracked equipment market – machines where every unplanned stoppage costs thousands of dollars per hour. Replacing the Brevini riduttori CTU3500, this 3-to-4-stage planetary drive delivers 35,000 Nm<\/strong> of output torque with a broad ratio range of 35:1 to 200:1<\/strong>, making it the right choice for large mining excavators, crawler drilling rigs and heavy offshore construction platforms.<\/p>\n

\"EP-CTU3500<\/p>\n

Product Overview<\/h2>\n

Served industries: 40-60 t mining hydraulic excavators, large rock drill crawler carriers, heavy tracked load-out platforms, large-scale tracked crane undercarriages and slow-speed tracked industrial transfer cars<\/strong>. The EP-CTU3500 is optionally supplied with a dual-speed engagement mechanism<\/strong> – allowing the operator to select a high-torque low-speed mode for digging and a higher-speed mode for tramming, all within the same gearbox body.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

The optional dual-speed mechanism<\/strong> works by hydraulically engaging or disengaging the third planetary stage. In low-speed mode all three or four stages are active, providing maximum torque for trench pushing and hard-ground travel. In high-speed mode the third stage is bridged by a hydraulically actuated clutch pack, effectively reducing the active stage count by one and increasing output shaft speed for fast tramming. Speed change occurs under load, managed by the machine’s travel control valve.<\/p>\n

The fourth stage (in 4-stage configurations) uses a wide-face planet gear<\/strong> extending the tooth contact length by 30% compared to standard width, directly increasing the continuous power rating of the output stage without increasing the housing diameter.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n\n\n
◼ Dual-Speed Option<\/strong>
Hydraulic ratio change in the gearbox – high torque for work, high speed for tramming. No separate two-speed motor needed.<\/td>\n		◼ Wide-Face Final Stage Planet<\/strong>
30% longer tooth contact face – increases continuous power capacity without housing upsizing.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
◼ 35:1 – 200:1 Ratio Range<\/strong>
Single platform covers diverse machine speed requirements from slow transfer cars to fast large excavators.<\/td>\n		◼ -35 degC Arctic Capability<\/strong>
Cold-rated FKM seals and low-pour-point PAO oil variant available for northern operations.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
◼ Brevini CTU3500 Direct Replacement<\/strong>
Same bolt pattern and hydraulic port layout – mounts directly in place of the original unit.<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

The housing is cast from GGG50 ductile iron<\/strong> and externally coated with epoxy-chromate primer + polyurethane topcoat<\/strong> (720-hour salt spray). Gear steels are 18CrNiMo7-6 vacuum-arc-remelted<\/strong> for maximum core toughness under impact loading. Wide-face planet gear blanks are individually balanced after machining to minimise vibration at high input speeds. The dual-speed clutch pack uses sintered metal friction discs<\/strong> rated for 50,000 engagement cycles without measurable wear.<\/p>\n

Typical Application Scenarios<\/h2>\n\n\n\n\n\n\n\n\n
Industry<\/th>\nMachine Type<\/th>\nDual-Speed Benefit<\/th>\n<\/tr>\n<\/thead>\n
Mining<\/td>\n50 t excavator, open-cast coal<\/td>\nHigh torque for face digging; fast travel between faces reduces cycle time.<\/td>\n<\/tr>\n
Drilling<\/td>\nLarge crawler rock drill carrier<\/td>\nSlow precise positioning at drill hole; fast tramming to next location.<\/td>\n<\/tr>\n
Civil<\/td>\nHeavy tracked load-out platform<\/td>\n200:1 ratio for ultra-slow heavy load positioning; stable brake hold on incline.<\/td>\n<\/tr>\n
Offshore<\/td>\nTracked platform leg jack system<\/td>\nHigh output torque for leg jacking; precise slow positioning during seafloor engagement.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Selection Guide<\/h2>\n
    \n
  1. Dual-Speed Required?<\/strong> – Specify if the machine requires two distinct travel speed ranges from a single motor.<\/li>\n
  2. Stage Count<\/strong> – 3-stage for 35:1-100:1; 4-stage for 100:1-200:1.<\/li>\n
  3. Continuous Duty vs. Intermittent<\/strong> – Confirm duty cycle for thermal rating; 55 kW continuous is the standard limit.<\/li>\n
  4. Clutch Engagement Frequency<\/strong> – For dual-speed, state expected speed changes per hour to confirm clutch life.<\/li>\n
  5. Arctic Service<\/strong> – Specify PAO VG 100 oil + low-temperature FKM seal grade for below -25 degC ambient.<\/li>\n<\/ol>\n
