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).
Revise também o temporizador de controlo em guinchos VFD: se a ativação do travão ocorre antes de o torque se estabilizar, pode ocorrer uma deriva breve. A ação corretiva deve abordar a causa raiz — nunca “apertar até segurar” sem verificar os limites de projeto e fatores de segurança.
