Genuine Electro-Hydraulic Drum Brake for Overhead Cranes
1. What is an Electro-Hydraulic Drum Brake?
The Electro-Hydraulic Drum Brake is a specialized safety braking device, widely used in overhead cranes, gantry cranes, conveyors, and heavy-duty industrial lifting systems.
The brake operates on a spring-applied and hydraulically released principle, controlled by an electro-hydraulic thruster. This mechanism ensures stable braking performance, fast response, and absolute safety in case of power failure (fail-safe).
It plays a critical role in load holding, motion stopping, and protecting the entire drive system in heavy industrial environments such as steel plants, ports, cement factories, and logistics centers.
1.2 Structure of the Electro-Hydraulic Drum Brake
Brake Drum
The contact surface directly engaged with the brake shoes, designed to withstand high wear and heavy loads during braking.
Brake Shoes
Made of specialized friction material to ensure stable braking force and long service life.
Brake Springs (Fail-safe)
Automatically apply the brake in case of power loss, enhancing system safety.
Electro-Hydraulic Thruster ED300-50
Provides precise brake release force, ensuring smooth and stable long-term operation.
Brake Frame & Levers
High-strength steel structure, resistant to vibration and heavy loads in harsh industrial environments.
1.2 Operating Principle
When power is supplied to the ED300-50 thruster, hydraulic force is generated to pull the lever mechanism, releasing the brake shoes from the drum, allowing the motor and transmission system to operate normally.
When power is cut off or a power failure occurs, hydraulic pressure is lost and the springs immediately press the brake shoes against the drum, stopping system movement. This fail-safe mechanism ensures maximum safety for both personnel and equipment.
