Wear of braking components: Brake shoes, friction pads and other consumable parts will gradually wear out with use. When their thickness is lower than the standard value, the braking force will significantly decrease.
Spring failure: The springs that provide braking force may experience fatigue, breakage or weakened elasticity over time.
Hydraulic/pneumatic system failure: Insufficient pressure, leakage or blockage in the oil line can all lead to reduced braking force.
Deformation of brake discs/ drums: Long-term use or overheating can cause deformation, resulting in a reduction of the friction contact area.
Installation and Adjustment Issues
Improper adjustment: Either too large or too small a brake clearance will affect the braking effect.
Installation errors: Deviations in concentricity and non-parallelism of the axis and other installation issues can lead to uneven braking force.
Loose connecting parts: Loose connecting parts such as bolts and pins will affect power transmission.
Improper operation: Overloading operation, frequent jogging and other inappropriate operations will accelerate the damage of the brake.
Insufficient maintenance: Failure to conduct regular inspections, clean oil stains or replace worn parts.
Poor lubrication: Excessive lubrication reduces the coefficient of friction, or insufficient lubrication leads to malfunction.
How to effectively prevent rollaway accidents?
Regular inspection system: Establish a special inspection form for the brake, check the wear of the brake components weekly, and measure the braking torque monthly.
Standardize maintenance and upkeep: Regularly replace wear parts as required by the equipment manual and clean braking components.
Operator training: Enhance safety operation training to eliminate violations such as overloading.
Technical upgrade and transformation: For outdated equipment, consider upgrading to a braking system with higher safety performance.
Double safety measures: Install dual braking systems or anti-rolling devices on key equipment.
