EP-PWD2100 Planetary Winch Drive Gearbox
Brevini PWD2100 Compatible Replacement | EVER POWER
El EP-PWD2100 is EVER POWER’s precision-engineered planetary winch drive gearbox, purpose-built as a direct replacement for the Brevini riduttori PWD2100. Combining robust load capacity with compact design, this unit delivers reliable performance in the most demanding lifting and pulling applications.
Descripción general del producto
Designed for marine winches, crane hoisting systems, offshore lifting platforms y construction material handlers, the EP-PWD2100 integrates a multi-stage planetary gear train inside a sealed housing. Its concentric shaft layout minimises installation footprint while delivering a maximum output torque of 21,000 Nm.
Core advantages at a glance: high torque density, low backlash, integrated multi-disc wet brake option, and full metric/imperial mounting compatibility.

Principio de funcionamiento
The EP-PWD2100 operates on the epicyclic (planetary) gear principle. The input sun gear meshes simultaneously with multiple planet gears orbiting around it, enclosed within an internally toothed ring gear fixed to the housing. This load-sharing arrangement distributes torque across several contact points simultaneously, achieving far greater torque density than parallel-shaft designs.
An optional integrated multi-disc wet brake is spring-engaged / hydraulically released, providing fail-safe load holding. The output drum flange is directly splined to the planet carrier, giving a rigid, zero-play load path.
Ventajas principales
| ● High Torque Density Achieves 21,000 Nm in a compact envelope, freeing installation space. |
● Precision Low Backlash Ground planet gears ensure backlash <= 8 arcmin for accurate positioning. |
| ● Integrated Brake Ready Bolt-on wet or dry brake interface eliminates external brake brackets. |
● All-Weather Sealing IP65 standard sealing (IP67 optional) for marine and outdoor duty. |
| ● Direct Bolt-In Replacement Mounting dimensions match Brevini PWD2100, requiring no machine modification. |

Estructura y tecnología de materiales
La carcasa está fundida a partir de high-grade ductile iron (GGG50) machined to ISO tolerances. Internal gears are manufactured from 20CrMnTi alloy steel, carburised, quenched and ground to DIN 5 accuracy. Planet pin bearings use double-row tapered roller bearings pre-loaded to minimise radial play. Shaft seals are FKM-grade fluoroelastomer, resistant to synthetic gear oils and hydraulic fluid contamination.
Escenarios de aplicación típicos
| Industria | Solicitud | How It Works |
|---|---|---|
| Marine | Anchor windlass, mooring winch | Hydraulic motor drives drum through planetary stages; spring brake holds load at rest. |
| Construction | Tower crane hoist | Electric motor feeds sun gear; high reduction ratio lifts heavy formwork with precision. |
| Minería | Personnel/cage hoist | Fail-safe wet brake ensures personnel safety during power loss events. |
| Forestry | Skidder winch | Compact form factor fits tight machine envelopes; sealed against wood debris ingress. |
Guía de selección
- Par de salida requerido (Nm) – Line pull x drum radius x safety factor.
- Relación de transmisión – Motor speed / desired drum speed.
- Input Interface – Hydraulic motor (SAE flange type, cc/rev) or electric motor (IEC frame).
- Brake Requirement – Wet multi-disc, dry disc, or no brake.
- Drum Attachment – Splined drum shaft, flange output or drum-integrated.
- Ambiente – Sealing class, operating temperature range, corrosion protection level.
