EP-PWD3200 Planetary Winch Drive Gearbox
Brevini PWD3200 Compatible Replacement | EVER POWER
The EP-PWD3200 from EVER POWER is engineered for demanding pull-and-hold operations requiring a wide ratio selection alongside robust sealing and long service intervals. Replacing the Brevini riduttori PWD3200, this unit delivers 32,000 Nm of output torque with ratio coverage up to 200:1 from a single gearbox body.
Product Overview
Target sectors: deck crane manufacturers, anchor handling tug & supply (AHTS) vessel builders, heavy civil construction and underground mining hoists. The EP-PWD3200’s ultra-wide ratio range means a single gearbox platform covers multiple winch configurations, reducing spare parts inventory. Key highlights: ratio coverage to 200:1, anti-corrosion epoxy-chromate coating, SAE/ISO dual-pattern flange, and optional tooth clutch output.

Working Principle
Three sequential planetary stages share the same central axis. The first stage provides an initial speed reduction of 4-6:1. The second and third stages further multiply torque, enabling the cumulative output ratio to reach 200:1. The tooth profile is an involute helical cut, providing quieter operation and higher load capacity compared to straight-cut spur gears at equivalent module.
Core Advantages
| ◆ Ultra-Wide Ratio 25:1-200:1 One platform covers diverse winch speed requirements, simplifying stock management. |
◆ Helical Tooth Profile Lower noise, higher load capacity and smoother torque transmission. |
| ◆ Dual-Pattern Input Flange SAE and ISO metric bolt patterns machined on the same flange face for universal motor fit. |
◆ Epoxy-Chromate Corrosion Protection Passes 720-hour neutral salt spray test. Suitable for C4/C5M corrosion zones. |
| ◆ Flexible Output Configuration Splined bore, drum flange or tooth clutch output – engineered to your machine interface. |

Structure and Material Technology
Gear blanks are precision-forged from 17CrNiMo6 alloy steel. Post-carburising hardness reaches HRC 58-62 on the tooth flank, ensuring wear resistance over 10,000+ operating hours. The main output bearing is a four-point contact ball bearing able to handle axial drum rope loads without auxiliary thrust bearings. Housing bore is honed to H7 tolerance for zero-slip bearing installation under shock loads.
Typical Application Scenarios
| Industry | Application | Scenario Notes |
|---|---|---|
| Marine | AHTS anchor chain handling | 200:1 ratio allows slow precise chain positioning with low-power motors. |
| Construction | Slipform concrete pump hoist | Smooth torque delivery prevents form bounce during continuous pour operations. |
| Energy | Wind turbine blade installation winch | Wide ratio range allows slow-speed fine positioning during blade bolting. |
| Mining | Shaft sinking kibble hoist | Integrated failsafe brake satisfies shaft sinker safety protocols. |
Selection Guide
- Define Line Pull (kN) and drum diameter to determine required output torque.
- Select Ratio from the 25:1-200:1 range based on target line speed and motor RPM.
- Specify Brake Type – wet spring-applied for offshore/mining; dry disc for land-based.
- Confirm Output Interface – spline size (DIN 5480 or custom), flange bolt circle.
- State Operating Environment – temperature extremes, wash-down pressure, explosion risk (ATEX options available).
