A strong inspection routine prevents most crane brake incidents. Daily (pre-shift) checks should include visual inspection for leaks (thrusters/hydraulics), abnormal noise, signs of dragging (unusual heat or smell), loose fasteners, damaged cables/hoses, and obvious lining or disc/brake wheel damage. Confirm the brake applies and releases normally during initial test movements.
Weekly or scheduled routine checks should measure lining thickness, verify air gap/shoe clearance, confirm thruster stroke or coil release performance, inspect pins/bushings for play, and check disc/brake wheel condition for scoring, blueing, or cracks. If switches are installed, test brake-open, wear, and limit interlocks.
Documente as descobertas e a taxa de desgaste—substituição preditiva reduz o tempo de inatividade. Para freios de guincho, inclua um teste de retenção controlada sob uma condição de teste segura. As inspeções devem seguir os manuais do OEM e os padrões de segurança aplicáveis ao guindaste, especialmente em ambientes de alta carga ou ao ar livre.
