500kg Double Speed Electric Chain Hoist with Motorized Trolley

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).
