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.
Productoverzicht
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.

Werkingsprincipe
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.
Kernvoordelen
| ▲ 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. |

Structuur- en materiaaltechnologie
Housing sections are machined from GGG50 nodulair gietijzer, coated in two-component epoxy primer to resist salt spray to ISO 12944-C5M. All gears are made from 17CrNiMo6 oppervlaktehardingsstaal, 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.
Typische toepassingsscenario's
| Industrie | Sollicitatie | Scenario-aantekeningen |
|---|---|---|
| Offshore O&G | Drill floor drawworks assist winch | Compact form fits moon-pool crane; IP66 withstands sea spray daily. |
| Harbour | Gantry crane trolley drive | High-cycle fatigue life ensures minimal planned maintenance intervals. |
| Forestry | Yarder winch main drum drive | Handles sudden shock loads; floating ring gear protects bearings. |
| Mijnbouw | Underground rope hoist | Wet brake meets underground safety regulations for personnel cages. |
Selectiegids
- Peak Torque (Nm) – Include dynamic factor (1.5-2.5 for shock loads).
