overhead or gantry crane

Manual release allows a brake to be opened without normal power—critical for maintenance, commissioning, and emergency recovery. On overhead and…

For overhead and gantry cranes, normally closed brakes are most common on safety-critical mechanisms, especially hoisting. “Normally closed” means the…

In a fail-safe brake, springs provide the fundamental braking force. Spring fatigue or breakage can reduce braking torque and compromise…

Disc brake air gap is the clearance between the pads and the disc when the brake is released. Correct air…

Drum/block brake clearance adjustment ensures the brake releases fully without dragging and engages quickly with predictable torque. While the exact…

Runout (wobble) in a brake wheel or disc causes the friction interface to contact unevenly as it rotates. This creates…

Cracks in a brake wheel or disc should be treated as a high-priority safety issue—especially on hoisting mechanisms. Cracks can…

Blue discoloration, heat spots, or rainbow patterns on a brake wheel or disc typically indicate overheating. This can result from…

Yes, many crane brake linings benefit from a controlled bedding-in (break-in) process after replacement. Bedding-in gradually matches the friction surface…

Crane brake linings should be replaced when they reach the manufacturer’s minimum thickness, show signs of cracking, glazing, delamination, or…
