EP-CTD3150 Planetary Track Drive Gearbox ?? 31,500 Nm<\/h1>\n

Brevini CTD3150 Compatible Replacement | EVER POWER<\/p>\n

The EP-CTD3150<\/strong> enters EVER POWER’s mid-to-heavy track drive range, delivering 31,500 Nm<\/strong> output torque in a sealed, brake-integrated planetary housing. Designed as a direct replacement for the Brevini riduttori CTD3150, this unit is optimised for 18-25 t tracked construction and earthmoving equipment where reliability over long operating hours is the primary purchasing criterion.<\/p>\n

\"EP-CTD3150<\/p>\n

Product Overview<\/h2>\n

The EP-CTD3150 primarily serves 18-25 t hydraulic excavators, large tracked dumpers, tracked road planers and medium crawler cranes<\/strong>. Its 3-stage planetary arrangement supports a ratio range of 25:1 to 130:1<\/strong>, and its cross-roller output bearing<\/strong> handles the unusually high moment loads generated when large excavators push lateral force against a trench wall during slope grading operations.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

Three cascading planetary stages reduce speed and multiply torque from the hydraulic travel motor. The cross-roller slewing ring output bearing<\/strong> is the key structural element ?? it replaces the standard back-to-back tapered roller arrangement used in lighter units and provides equivalent axial, radial and overturning moment capacity in a narrower axial space. This allows the EP-CTD3150 to fit the same track frame pocket as the Brevini CTD3150 while handling the higher moment loads of large excavator grading operations.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
▲ Cross-Roller Output Bearing<\/strong>
Handles combined axial, radial and moment loads from trench-wall lateral forces without separate thrust bearing.<\/div>\n<\/td>\n
\n
▲ 25:1 – 130:1 Ratio Range<\/strong>
Wide range covers both fast tramming speed and maximum grading torque in one platform.<\/div>\n<\/td>\n<\/tr>\n
\n
▲ IP68 Deep-Submersion Seal<\/strong>
Tested to 3 m submersion ?? handles flooded excavation pits and river-crossing work.<\/div>\n<\/td>\n
\n
▲ -30 degC Cold Start<\/strong>
Arctic-grade synthetic oil and low-temperature FKM seals ensure clean cold-morning start.<\/div>\n<\/td>\n<\/tr>\n
\n
▲ Direct CTD3150 Replacement<\/strong>
Same flange, spline and brake port layout as the Brevini unit ?? zero adaptation required.<\/div>\n<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

The cross-roller slewing ring<\/strong> is manufactured from 42CrMo4 through-hardened steel<\/strong>, raceways ground to P5 accuracy class. Planet gears use 17CrNiMo6 carburised steel<\/strong> ground to DIN 5 accuracy. The output flange register face is precision-turned to 0.02 mm total runout for accurate sprocket mounting without shim adjustment. The housing exterior carries a two-coat epoxy primer + polyurethane topcoat<\/strong> paint system rated to 500 hours salt spray.<\/p>\n

Typical Application Scenarios<\/h2>\n\n\n\n\n\n\n\n
Industry<\/th>\nMachine \/ Use<\/th>\nKey Requirement<\/th>\n<\/thead>\n
Earthmoving<\/td>\n20 t excavator, slope grading<\/td>\nHigh lateral moment load during slope trimming ?? cross-roller bearing essential.<\/td>\n<\/tr>\n
Road Building<\/td>\nLarge tracked cold planer, 18 t class<\/td>\nHigh thrust force at slow milling speed; wide ratio range provides correct speed.<\/td>\n<\/tr>\n
Crane<\/td>\n24 t tracked crane undercarriage<\/td>\nCross-roller bearing handles boom swing moment transmitted through undercarriage.<\/td>\n<\/tr>\n
Mining<\/td>\nMedium dump crawler, open cast coal<\/td>\nHigh-cycle travel over rough terrain; IP68 seal handles water and coal dust.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Selection Guide<\/h2>\n
    \n
  1. Lateral Moment Load (kNm)<\/strong> ?? Slope grading and dozing operations generate high moment; confirm cross-roller bearing is adequate.<\/li>\n
  2. Required Ratio<\/strong> ?? 25:1 for fast large-machine tramming; 130:1 for maximum grading torque.<\/li>\n
  3. Cold Start Temperature<\/strong> ?? Specify if operating below -20 degC for cold-grade oil and seal.<\/li>\n
  4. Submersion Depth<\/strong> ?? Standard IP68 to 3 m; deeper service available on request.<\/li>\n
  5. Motor Shaft<\/strong> ?? Provide motor model for direct spline\/flange confirmation.<\/li>\n<\/ol>\n
