EP-CTD3200 Planetary Track Drive Gearbox ?? 32,000 Nm<\/h1>\n

Brevini CTD3200 Compatible Replacement | EVER POWER<\/p>\n

The EP-CTD3200<\/strong> is EVER POWER’s high-cycle workhorse for 20-30 t tracked equipment, delivering 32,000 Nm<\/strong> output torque with a 4-planet output carrier that extends gear tooth life by approximately 25% versus a conventional 3-planet design. Engineered as a form-and-function replacement for the Brevini riduttori CTD3200, this unit is specified by maintenance teams who prioritise longer service intervals over minimum purchase price.<\/p>\n

\"EP-CTD3200<\/p>\n

Product Overview<\/h2>\n

The EP-CTD3200 targets 25-30 t hydraulic excavators, large tracked stabilisers, crawler-type demolition machines and heavy tracked road-building equipment<\/strong>. The 4-planet output carrier<\/strong> is the key differentiator ?? four simultaneous tooth contacts share the output torque equally, reducing per-tooth stress and making this unit measurably more suited to continuous duty cycles than the 3-planet alternatives it replaces.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

The 3-stage arrangement uses standard 3-planet modules in stages 1 and 2, optimised for high input speed tolerance. The third stage upgrades to a 4-planet carrier<\/strong>. Mathematically, distributing output torque across four planets instead of three reduces the load at each tooth contact by 25% at equivalent torque. This improvement either extends tooth fatigue life by the same proportion at rated torque, or increases the momentary overload tolerance to 2.8x rated torque<\/strong> ?? critical for excavators striking buried rock or concrete during trench digging.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
► 4-Planet Output Stage<\/strong>
~25% lower per-tooth stress ?? quantifiably longer service intervals on high-hour machines.<\/div>\n<\/td>\n
\n
► 2.8x Overload Tolerance<\/strong>
Buried rock strikes and concrete encounters are absorbed without tooth damage.<\/div>\n<\/td>\n<\/tr>\n
\n
► 28:1 – 140:1 Wide Ratio<\/strong>
Covers fast tramming and maximum digging torque requirements from one product.<\/div>\n<\/td>\n
\n
► IP68 Sealed<\/strong>
Factory-tested submersion sealing for flooded excavation and stream-crossing duty.<\/div>\n<\/td>\n<\/tr>\n
\n
► Direct CTD3200 Drop-In<\/strong>
Identical flange, spline and brake port layout ?? zero adaptation at installation.<\/div>\n<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

Output stage planet gears are forged from 17CrNiMo6 vacuum-degassed steel<\/strong> for superior core toughness. Carburising depth is maintained at 0.9-1.2 mm; tooth profiles are ground to ISO accuracy grade 5. Each planet journal runs on a needle roller bearing assembly<\/strong> with a hardened shaft, achieving higher radial stiffness than bush bearings at the same pin diameter. The housing flange face is finish-turned to 0.015 mm flatness to ensure correct brake disc stack geometry without shimming.<\/p>\n

Industry<\/th>\nMachine \/ Use<\/th>\nKey Requirement<\/th>\n<\/thead>\n
Earthmoving<\/td>\n28 t excavator, mixed rock\/clay site<\/td>\nBuried rock impacts at 2.8x rated torque ?? absorbed without tooth failure.<\/td>\n<\/tr>\n

Selection Guide<\/h2>\n
    \n
  1. Operating Hours per Year<\/strong> ?? Machines running 6,000+ hours\/year benefit most from the 4-planet extended life.<\/li>\n
  2. Soil\/Rock Conditions<\/strong> ?? Mixed or hard-rock sites require the 2.8x overload capacity; specify accordingly.<\/li>\n
  3. Ratio<\/strong> ?? 28:1 for fast large machines; 140:1 for slow-speed high-torque applications.<\/li>\n
  4. Oil Grade<\/strong> ?? VG 220 for standard duty; VG 320 for high-temperature continuous operation.<\/li>\n
  5. Motor Shaft<\/strong> ?? Provide motor specification (cc\/rev, flange, shaft) for direct ratio confirmation.<\/li>\n<\/ol>\n
