Overhead Crane Brakes Mechanism

 

The rotating element in a disc Brakes's friction pair is a metal disc working on its end faces, called a Brakes disc. The friction elements clamp the disc from both sides, producing braking. The fixed element has various structural forms, and overhead crane Brakes mechanism can generally be categorized as caliper disc and full disc.

overhead crane Brakes mechanism are hydraulically controlled, with the main components including the Brakes disc, wheel cylinder, caliper, and oil pipe. overhead crane Brakes mechanism offer rapid heat dissipation, light weight, simple construction, and easy adjustment. They are particularly resistant to high temperatures under high loads, provide stable braking, and are resistant to mud and water intrusion. overhead crane Brakes mechanism apply force along the disc, preventing bending moments on the Brakes axis and resulting in a small radial dimension.

Model Signifcance

 

Order Example

(SBD250-A-1600×30 IRL means its rated clamping force is 250KN with release limit switch and A-type safety Brakes of I version installation. The Brakes disc diameter is 1600mm and the disc thickness is 30mm.)
