Electro-Hydraulic Brake

Drum brakes use a brake transmission mechanism to press the brake shoes against the inner side of the brake drum, thereby generating braking force. This allows the wheels to decelerate as needed or come to a stop in the shortest distance, ensuring driving safety and reliable parking without automatic slippage.

Detailed Introduction

Electro-hydraulic block brakes are widely used for deceleration or parking braking in mechanical drive devices such as cranes, metallurgy, mining, ports, docks, and construction machinery. They offer safe and reliable performance, smooth braking, and high operating frequency. The main swinging hinge points are equipped with self-lubricating bearings, providing high transmission efficiency and long service life, with no need for lubrication during use.

Compliant Standards

Installation dimensions comply with the JB/ZQ4388-1997 standard. Depending on user requirements, brake linings can be installed in two forms: riveted or inserted (specify when ordering).

Usage Conditions

Ambient temperature: -20℃ to +50℃

Relative air humidity not exceeding 90%

No flammable, explosive, or corrosive gases in the working environment

Altitude at the usage location complies with GB755-2000

For outdoor use exposed to rain, snow, or corrosive gases and media, corrosion-resistant products should be used.
