500kg-5000kg Electric Chain Hoist with Variable-Frequency Motor

High-Performance Electric Chain Hoist with Variable-Frequency Motor

HHBB Type Electric Chain Hoist Brief Description

1. Smooth lifting and precise positioning:

Smooth gear transmission and smooth chain operation with minimal vibration.

Standard lifting speeds typically range from 4-8 m/min. Some models support dual-speed (fast/slow) or variable frequency drive for precise positioning.

2. Safety and reliability:

Mechanical overload protection: A built-in friction clutch or torque limiter automatically engages when the load exceeds the rated value (e.g., 110%), protecting the motor and structure.

Upper and lower limit switches: Automatically cut off power to the motor to prevent accidents caused by excessive chain retraction and extension.

Dual braking system: Commonly equipped with:

Electromagnetic disc brake: Automatically engages upon power failure (safety brake) to prevent heavy objects from falling.

Mechanical brake (auxiliary): Provides additional braking protection at the motor shaft end.

Low voltage control (24V/42V): The pushbutton switch uses a safe voltage for safer operation.

Chain guide/guard: Prevents chain derailment or jamming, protecting the operator.

3. Easy Maintenance and High Durability:

Chain lubrication requirements are minimal (self-lubricating chains or regular grease application are sufficient).

The modular design allows for easy access and replacement of key components (such as the motor and brake).

The housing is typically constructed of sturdy aluminum alloy or steel, with an IP54/IP55 protection rating (dustproof and water-jet proof), suitable for general industrial environments.

4. High Efficiency and Energy Saving:

Low power (500kg-class motors typically have a power of around 0.75kW to 1.5kW) and low energy consumption.

Quick start and stop ensure high efficiency.
