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).
Juga tinjau waktu kontrol pada hoist VFD: jika pengaturan rem terjadi sebelum torsi stabil, dapat terjadi drift singkat. Tindakan korektif harus menangani akar penyebab—jangan pernah “mengencangkan sampai rem menahan” tanpa memverifikasi batas desain dan faktor keselamatan.
