Load creep after brake application indicates that holding torque is not being fully transferred to the load. Start by confirming whether the brake itself is slipping: check lining condition (worn, glazed, contaminated), spring force (fail-safe brakes), air gap/clearance, and friction surface condition (disc/brake wheel scoring, heat damage). A controlled static holding test at rated load is often the fastest confirmation.
Next, rule out drivetrain slip that can mimic brake slip: coupling slippage, keyway damage, loose hubs, gearbox internal issues, or a drum/rope anchoring problem. If the brake locks the shaft but the load still moves, the fault may be downstream (drum, rope, reeving).
También revise la temporización del control en los cabrestantes VFD: si el freno se activa antes de que el torque se estabilice, puede ocurrir una deriva breve. La acción correctiva debe abordar la causa raíz—nunca “ajustar hasta que sostenga” sin verificar los límites de diseño y los factores de seguridad.
