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.
Documentar hallazgos y tasa de desgaste de tendencia—el reemplazo predictivo reduce el tiempo de inactividad. Para los frenos de cabrestante, incluir una comprobación de retención controlada bajo una condición de prueba segura. Las inspecciones deben seguir los manuales del OEM y las normas de seguridad de grúas aplicables, especialmente en entornos de alta carga o exteriores.
