Hydraulic / Electric Winches

JSJ Series — Hydraulic Winches

JSJ hydraulic winches are custom pulling, lifting and towing winches with motor, planetary gearbox, brake, valve and drum options.

Focus: Line pull, rope capacity and brake safety
Engineering boundary: Final sizing, configuration and interface require JST engineering confirmation.

Product Overview

Series capability and selection context

JSJ hydraulic winches are custom pulling, lifting and towing winches with motor, planetary gearbox, brake, valve and drum options.

Winch selection covers compact pulling duty through heavy line-pull applications up to about 600 kN depending on configuration.

Drum diameter, drum length, rope capacity, line speed and frame layout can be designed for the machine.

Spring-applied hydraulic-release brake and valve options support controlled holding, lifting and pulling duty.

Technical Data

Applications

Crawler cranes and piling rigs: main or auxiliary pulling, lifting and positioning tasks.
Rotary drilling rigs: controlled rope handling in drilling and foundation equipment.
Marine and offshore equipment: deck winches, mooring, towing and handling systems with corrosion protection options.
Mining and tunneling machinery: heavy pulling, equipment recovery and underground material handling.
Forestry and logging: pulling, dragging and positioning logs or equipment in harsh outdoor conditions.
Vehicle-mounted recovery systems: custom recovery winches for trucks, trailers and special vehicles.
Industrial lifting and pulling: steel plants, shipyards, construction sites and custom hydraulic machinery.

Selection Guide

Wide pulling range: JSJ winches can be configured from compact utility winches to heavy-duty units up to about 600 kN rated line pull.
Integrated hydraulic drive: hydraulic motor, planetary gearbox, multi-disc brake, balance valve, distributor and drum can be supplied as one tested assembly.
Custom drum and rope capacity: drum diameter, drum length, rope groove, rope outlet direction and rope capacity can be adapted to the machine layout.
Stable braking and load control: spring-applied hydraulic release brakes and balance valves support safer holding, lowering and positioning under load.
Compact planetary reduction: high torque density helps fit strong winch performance into limited installation space.
OEM and replacement design support: JST can develop winches for new equipment or replacement projects where imported winches are difficult to source.
Rated line pull: specify the required pulling force and whether it is first-layer or outer-layer line pull.
Rope diameter and rope length: these decide drum size, rope layers and fleet angle requirements.
For accurate selection, send the working conditions instead of only asking for a model number. The most important parameters are:

Engineering Notes

Rated line pull: From compact custom units to about 600 kN depending on configuration.
Rope diameter: Approx. 8-60 mm, project dependent.
Rope capacity: From a few metres to 1,000+ m depending on drum diameter, drum length and rope layers.
Line speed: Configured from available flow, load requirement and operator handling needs.
Operating pressure: Typically 16-25 MPa; custom options available according to hydraulic system.
Drive layout: Hydraulic motor + planetary gearbox + drum for compact high-torque output.
Brake system: Spring-applied hydraulic-release multi-disc brake for load holding and controlled lowering.
Control valves: Balance valve, relief valve, distributor and speed-control options.

Final sizing, configuration and interface require JST engineering confirmation.
