EP-CTU3150 Planetary Track Drive Gearbox<\/h1>\n

Brevini CTU3150 Compatible Replacement | EVER POWER<\/strong><\/p>\n

The EP-CTU3150<\/strong> is EVER POWER’s precision-built planetary track drive gearbox, engineered as a direct replacement for the Brevini riduttori CTU3150. Delivering 31,500 Nm<\/strong> output torque within a compact, flange-mounted housing, this unit keeps excavators, crawler cranes and track-type construction machines moving reliably in the toughest job-site conditions.<\/p>\n

\"EP-CTU3150<\/p>\n

Product Overview<\/h2>\n

The EP-CTU3150 serves construction, mining, drilling and port-handling industries<\/strong> wherever compact track drives are required. Its sealed, oil-bath lubricated planetary stages provide maintenance-free operation across extended service intervals, while the integrated multi-disc spring brake ensures the machine holds position on slopes whenever the hydraulic motor is de-energised.<\/p>\n

Key highlights: 31,500 Nm rated output torque, 2-stage planetary reduction, SAE-B\/ISO motor flange, spring-applied failsafe brake, IP68 sealing.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

The EP-CTU3150 uses a two-stage epicyclic (planetary) arrangement<\/strong>. High-speed, low-torque input from the hydraulic travel motor enters the first-stage sun gear. Multiple planet gears orbit the sun and react against a fixed ring gear, multiplying torque at the first-stage planet carrier. That carrier becomes the input shaft to the second stage, providing a final cumulative reduction of up to 80:1.<\/p>\n

The integrated spring-applied, hydraulically released multi-disc brake<\/strong> engages automatically whenever hydraulic pressure is removed – either by operator command or in the event of a system fault – preventing uncontrolled machine movement on gradients.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n\n\n
● High Torque Density<\/strong>
31,500 Nm in a compact flanged body – fits original machine envelope without modification.<\/td>\n		● IP68 Sealed<\/strong>
Fully submerged-capable sealing handles deep trench work, river crossings and pressure wash cycles.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
● Failsafe Spring Brake<\/strong>
Spring-applied brake activates on power loss, satisfying slope-hold requirements on grades up to 35 deg.<\/td>\n		● Long Service Intervals<\/strong>
Oil-bath lubrication and sealed housing deliver 2,000+ hour oil change intervals.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
● Drop-In Replacement<\/strong>
Mounting dimensions match Brevini CTU3150 – no machine frame modification required for retrofit.<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

The housing is precision-cast from GGG50 ductile iron<\/strong> and machined to ISO H7 bore tolerances. Planet gears are manufactured from 20CrMnTi case-hardening steel<\/strong>, carburised and ground to DIN 5 accuracy. The output bearing is a crossed-roller slewing ring<\/strong> designed to handle combined axial, radial and moment loads from the track chain and idler tension. All O-ring face seals are NBR\/FKM compound<\/strong>, rated for continuous operation in hydraulic oil, muddy water and diesel-contaminated environments.<\/p>\n

Selection Guide<\/h2>\n
    \n
  1. Machine Operating Weight (t)<\/strong> – Determines required drawbar pull and hence output torque.<\/li>\n
  2. Travel Speed (km\/h)<\/strong> – Defines required ratio given motor displacement and sprocket pitch diameter.<\/li>\n
  3. Motor Interface<\/strong> – SAE-B, SAE-C, or ISO flange; shaft or spline input.<\/li>\n
  4. Brake Release Pressure<\/strong> – Confirm available hydraulic pressure (typically 20-35 bar).<\/li>\n
  5. Ground Conditions<\/strong> – Wet, abrasive or chemically aggressive environments may need upgraded seal specification.<\/li>\n<\/ol>\n
