EP-PWD3150 Heavy-Duty Planetary Winch Drive Gearbox<\/h1>\n

Brevini PWD3150 Compatible Replacement | EVER POWER<\/strong><\/p>\n

When continuous-duty offshore or heavy-construction winching demands absolute reliability, the EP-PWD3150<\/strong> delivers. Engineered by EVER POWER as a form-and-function replacement for the Brevini riduttori PWD3150, this unit provides 31,500 Nm<\/strong> output torque with exceptional fatigue life and sealed performance in hostile environments.<\/p>\n

\"EP-PWD3150<\/p>\n

Product Overview<\/h2>\n

Primary industries: offshore oil and gas, subsea construction vessels, harbour cranes, heavy forestry machines and large industrial hoists<\/strong>. The EP-PWD3150 uses a fully floating ring-gear design that automatically compensates for minor misalignments between the motor and drum, extending service life in high-vibration environments. The unit ships fully oil-filled and tested, with brake-integrated models pre-set for commissioning under two hours.<\/p>\n

Working Principle<\/h2>\n

The EP-PWD3150 utilises a three-stage compound planetary arrangement<\/strong>. Input from the hydraulic motor rotates the first-stage sun gear; the planet carrier of stage 1 becomes the sun gear shaft of stage 2, and similarly for stage 3. This cascading arrangement achieves very high reduction ratios (up to 150:1) in a single coaxial housing. An optional failsafe spring brake<\/strong> located between input and stage 1 holds the load automatically on power loss.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n\n\n
▲ 3-Stage Compound Design<\/strong>
Up to 150:1 ratio in one unit – no tandem coupling required.<\/td>\n		▲ Floating Ring Gear<\/strong>
Self-compensates for motor\/drum misalignment, reducing bearing stress.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
▲ IP66 Sealed<\/strong>
Withstands high-pressure washdowns and wave splash.<\/td>\n		▲ Pre-Tested Delivery<\/strong>
Each unit is pressure-tested and run-in before shipment.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
▲ 30-50% Cost Saving vs OEM<\/strong>
Comparable technical specification at significantly lower total cost of ownership.<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

Housing sections are machined from GGG50 ductile iron<\/strong>, coated in two-component epoxy primer to resist salt spray to ISO 12944-C5M. All gears are made from 17CrNiMo6 case-hardening steel<\/strong>, carburised to 0.8-1.2 mm case depth, then ground to DIN 5 quality. Each planet journal runs on spherical roller bearings<\/strong> to accommodate shock-load spikes up to 2.5x rated torque.<\/p>\n
