EP-PWD3150 Heavy-Duty Planetary Winch Drive Gearbox
Brevini PWD3150 Compatible Replacement | EVER POWER
When continuous-duty offshore or heavy-construction winching demands absolute reliability, the EP-PWD3150 delivers. Engineered by EVER POWER as a form-and-function replacement for the Brevini riduttori PWD3150, this unit provides 31,500 Nm output torque with exceptional fatigue life and sealed performance in hostile environments.
Product Overview
Primary industries: offshore oil and gas, subsea construction vessels, harbour cranes, heavy forestry machines and large industrial hoists. 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.

動作原理
The EP-PWD3150 utilises a three-stage compound planetary arrangement. 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 located between input and stage 1 holds the load automatically on power loss.
主な利点
| ▲ 3-Stage Compound Design Up to 150:1 ratio in one unit – no tandem coupling required. |
▲ Floating Ring Gear Self-compensates for motor/drum misalignment, reducing bearing stress. |
| ▲ IP66 Sealed Withstands high-pressure washdowns and wave splash. |
▲ Pre-Tested Delivery Each unit is pressure-tested and run-in before shipment. |
| ▲ 30-50% Cost Saving vs OEM Comparable technical specification at significantly lower total cost of ownership. |

構造と材料技術
Housing sections are machined from GGG50 ductile iron, coated in two-component epoxy primer to resist salt spray to ISO 12944-C5M. All gears are made from 17CrNiMo6 case-hardening steel, carburised to 0.8-1.2 mm case depth, then ground to DIN 5 quality. Each planet journal runs on spherical roller bearings to accommodate shock-load spikes up to 2.5x rated torque.
典型的なアプリケーションシナリオ
