Overhead cranes carry ladles, coils and slabs through steel plants, and their motors and brakes work through heavy duty cycles in heat and dust. A failed brake or overheated hoist motor is both a production stop and a safety event. Reliable lifting equipment comes from trending temperature, vibration, brake wear and operating cycles instead of waiting for a fault. This guide covers that routine and how crane maintenance software supports it.

Motor and Brake Condition Checks
| Item | Check | Warning Sign | Response |
|---|---|---|---|
| Hoist motor | Winding and bearing temperature | Heat rising over time | Inspect cooling and load |
| Motor bearings | Vibration and noise | Rising vibration trend | Plan bearing replacement |
| Brake pads or discs | Thickness, glazing, contamination | Uneven wear, oil or dust | Clean or replace |
| Brake gap | Air gap and release | Dragging or late release | Adjust and retest |
| Brake torque | Holding test | Load creep | Remove from service until fixed |
| Electrical | Current, insulation, connections | Unbalanced current | Electrical inspection job |
Plan Crane Inspections Before Faults Appear
Build crane inspection routes and brake checks into scheduled work orders.
Why Duty Cycles Matter
Calendar-based only
- Same interval for every crane
- Heavy-duty cranes wear ahead of schedule
- Lightly used cranes get unneeded work
Usage-based
- Intervals follow hours, lifts or starts
- Duty severity shapes the plan
- Work lands closer to actual wear
Daily to Annual Inspection Rhythm
Every shift Operator checks for noise, drift and brake response.
Weekly Technician checks brakes, limit switches and wire rope condition.
Monthly Record temperature and vibration readings for trending.
Annual Full inspection by a qualified person to applicable standards.
Compliance and Records
- Keep dated inspection records for each crane.
- Record who inspected and what was found.
- Tie defects to work orders with closing notes.
- Follow your local regulations and manufacturer guidance.

Frequently Asked Questions
How often should crane brakes be inspected?
Follow manufacturer and regulatory guidance, and shorten intervals for severe duty.
Follow manufacturer and regulatory guidance, and shorten intervals for severe duty.
What signals a motor problem early?
Rising temperature, vibration or current compared with the baseline.

Can inspections be done on mobile?
Yes. Book a demo to see mobile checklists.

Does it track duty cycles?
Hours or cycle counts you record can trigger preventive tasks.
