Double Speed Electric Chain Hoist With Motorized Trolley 500kg

HHBB Type Electric Chain Hoist Brief Description

1. Core Structure and Operating Principle
Chain Drive: A high-strength alloy steel chain (rather than a wire rope) is used as the load-bearing mechanism. Chains are wear-resistant, corrosion-resistant, and tangle-resistant, and their small bend radius makes them ideal for compact spaces.

Gear Reduction System: A multi-stage gear system (typically planetary or helical) reduces the motor's high speed to a low-speed, high-torque output, driving the sprocket to lift the chain.

Squirrel Cage Motor: Typically equipped with a single-phase or three-phase asynchronous motor, this motor offers a simple structure and easy maintenance. Some high-end models utilize variable-frequency motors for stepless speed regulation.

Built-in Design: Core components such as the motor, reduction gearbox, brake, and sprocket are highly integrated within the compact hoist body, resulting in a lightweight structure.

2. Core Features
Lightweight and Portable, Space-Saving:

Lightweight (typically in the tens of kilograms) and compact size.

Easily mounted on an I-beam track, cantilever bracket, or fixed lifting point, the hoist requires minimal space.

Simple and Flexible Operation:

Handle Button Control: Standard handheld push-button switches (up, down, and left and right) provide intuitive and ergonomic operation.

Optional Wireless Remote Control: Select models support wireless remote control for greater control flexibility and a wider field of view.

Flexible Operation: Available in two main types: fixed (up and down lift only) and running (the hoist can move horizontally along the I-beam track).
