Brevini CTU3200 Compatible Replacement | EVER POWER<\/strong><\/p>\n

The EP-CTU3200<\/strong> by EVER POWER delivers 32,000 Nm<\/strong> output torque in a compact 2-to-3-stage sealed planetary housing, engineered as a cost-effective, form-fit replacement for the Brevini riduttori CTU3200. Designed for mid-to-large tracked construction and earthmoving equipment, this unit combines wide ratio coverage with all-terrain sealing to minimise unplanned downtime.<\/p>\n

\"EP-CTU3200<\/p>\n

Product Overview<\/h2>\n

Primary markets: 18-25 t hydraulic excavators, crawler-mounted pipe layers, tracked soil stabilisers and large tunnelling machines<\/strong>. The EP-CTU3200 features an extended ratio range of 25:1 to 120:1<\/strong> achieved through a configurable 2-or-3-stage arrangement, allowing a single part number to serve machines with significantly different travel speed requirements without any housing change.<\/p>\n

Working Principle<\/h2>\n

In 3-stage configuration, the first two stages use a standard 3-planet arrangement for high input speed tolerance; the final stage upgrades to a 4-planet carrier<\/strong> for enhanced torque capacity at the output. This hybrid arrangement allows the EP-CTU3200 to handle both the high-speed continuous travel phase and the high-torque low-speed pushing phase of excavator track operation without thermal de-rating.<\/p>\n

The floating sun gear shaft<\/strong> design automatically centres the load distribution across all planet gears, compensating for minor shaft misalignment caused by track chain tension deflection and chassis flexion during operation.<\/p>\n

Core Advantages<\/h2>\n

\"EVER<\/p>\n\n\n\n\n\n\n
▲ 2-or-3-Stage Flexibility<\/strong>
One part number covers 25:1-120:1 ratio range – simplifies procurement and spares stocking.<\/td>\n		▲ Floating Sun Gear<\/strong>
Self-equalises planet load distribution, extending tooth life under chassis deflection loads.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
▲ 4-Planet Output Stage<\/strong>
Higher tooth contact count reduces root stress, supporting rated torque at extreme duty cycle.<\/td>\n		▲ -30 degC Cold Start<\/strong>
Arctic-grade synthetic oil and cold-rated FKM seals ensure clean cold-morning engagement.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
▲ Direct Brevini CTU3200 Replacement<\/strong>
Same flange pattern, spline spec and brake port locations – swap in place with no machine modification.<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

All gear blanks are precision-forged from 17CrNiMo6 case-hardening steel<\/strong>, vacuum degassed for superior core impact toughness. Post-carburising case depth is controlled to 0.9-1.2 mm; tooth flanks are profile-ground to ISO\/DIN accuracy class 5. The output flange is machined with a T-slot register face<\/strong> for accurate sprocket centering without adjustment shims. O-ring face seals use HNBR compound<\/strong> for resistance to biodegradable hydraulic fluids increasingly specified on European and Japanese job sites.<\/p>\n

Typical Application Scenarios<\/h2>\n\n\n\n\n\n\n\n\n
Industry<\/th>\nMachine Type<\/th>\nKey Requirement<\/th>\n<\/tr>\n<\/thead>\n
Construction<\/td>\n20 t excavator<\/td>\nHigh-cycle travel; 3-stage for fast tramming speed on road.<\/td>\n<\/tr>\n
Tunnelling<\/td>\nCrawler-mounted shotcrete robot<\/td>\nSlow precise positioning in confined tunnel bores; high torque for gradients.<\/td>\n<\/tr>\n
Pipeline<\/td>\nTracked pipelayer (side-boom crane)<\/td>\nSmooth slow-speed travel alongside open trench with heavy suspended pipe.<\/td>\n<\/tr>\n
Agriculture<\/td>\nLarge tracked harvester chassis<\/td>\nWide ratio range handles both field travel speed and headland turning torque.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Selection Guide<\/h2>\n
    \n
  1. Drawbar Pull (kN)<\/strong> – Required traction force on worst-case gradient x safety factor (1.3 minimum).<\/li>\n
  2. Stage Count<\/strong> – Choose 2-stage for max travel speed; 3-stage for maximum torque at given motor size.<\/li>\n
  3. Motor Shaft Interface<\/strong> – Splined (DIN 5480) or keyed shaft; confirm bore diameter.<\/li>\n
  4. Brake Release Pressure<\/strong> – 20-40 bar available hydraulic pressure to release spring brake.<\/li>\n
  5. Biodegradable Oil Requirement<\/strong> – Specify HNBR seals if bio-hydraulic fluid is used on site.<\/li>\n<\/ol>\n
