JK/JM Series Electric Winch

Overview

The JK/JM Series Electric Winch is a common lifting equipment powered by an electric motor. Based on wire rope speed, it is divided into JK Series Fast Winch (rated rope speed approx. 30m/min) and JM Series Slow Speed Winch (rated rope speed approx. 7-12m/min) . This product series features high versatility, compact structure, small size, light weight, large lifting capacity, and easy transfer. It is widely used for material lifting or horizontal traction in construction, water conservancy projects, forestry, mines, docks, etc., and can also serve as supporting equipment for modern electronically controlled automatic production lines .

Introduction

The JK/JM Series Electric Winch consists of core components such as the motor, coupling, brake, gearbox, and drum, all mounted on a common frame . Powered by an electric motor, it drives the drum through an elastic coupling, a three-stage enclosed gear reducer, and a jaw coupling, with electromagnetic braking . The series features mature and reliable design, meeting lifting requirements under various working conditions.

Features

• Two Speed Options: JK fast type suitable for applications requiring quick lifting and lowering; JM slow speed type suitable for installation projects requiring precise positioning and good speed regulation performance .

• Efficient Transmission System: Three-stage enclosed gear reducer ensures smooth transmission, low noise, and high efficiency .

• Reliable Braking Performance: Electromagnetic braking provides quick and reliable stopping, ensuring safe load suspension .

• Durable Construction: Compact structure, small size, light weight, yet large lifting capacity and long service life .

• Jaw Coupling: Jaw coupling drives the drum, ensuring reliable connection and high torque transmission .

• Wide Adaptability: Suitable for vertical lifting, horizontal or inclined traction of heavy objects, as well as dragging materials and equipment on slopes or flat ground

Specifications

Product Structure

Structural Components

1. Motor: Crane-duty motors such as Y series, YZR series, featuring high starting torque and strong overload capacity .

2. Coupling: Elastic coupling connecting motor and gearbox, providing buffering and vibration damping .

3. Brake: Electromagnetic brake, normally closed design, releases when energized and immediately brakes when power is off, ensuring safety .

4. Gearbox: Three-stage enclosed gear reducer with precision-machined gears for smooth transmission and low noise .

5. Drum: Driven by jaw coupling, featuring spiral grooves for orderly wire rope arrangement .

6. Base: Integral steel base welded from profiles, rigid structure, easy installation, no deformation under heavy loads .

7. Wire Rope: Cross-wound steel wire rope with high safety factor and good wear resistance .
