CQPL-A Series Pneumatic Disc Brake

CQPL‑A series pneumatic disc brakes are normally‑closed, spring‑applied, pneumatically released disc brakes, mainly used for service braking, safety braking and load holding in various industrial machinery, conveyors, cranes and heavy equipment.

Basic Identification

Model: CQPL‑A Series

Type: Pneumatic disc brake

Operation: Normally closed • Spring applied • Pneumatically released

Function: Braking, emergency stop, safety holding

Working Principle

Without air pressure: Built‑in springs clamp the brake disc to achieve braking.

With air pressure: Pneumatic cylinder overcomes spring force and opens the brake.

Fail‑safe: Automatically brakes when air pressure is lost.

Key Features

Compact structure, high braking torque

Stable performance, fast response

Pneumatic control, easy to operate

Wear‑resistant asbestos‑free friction pads

Adjustable brake clearance

Suitable for frequent and heavy‑duty working conditions

Typical Applications

Conveyors, mixing equipment, cable machinery

Cranes, hoists, winding machinery

Metallurgical, mining, port and packaging machinery

Systems requiring pneumatic braking

Short version 

CQPL‑A series pneumatic disc brakes are normally‑closed, spring‑applied, pneumatically released safety brakes used for braking and holding in industrial machinery and conveying systems.
