Crane electrical equipment operates in a special mode of frequent starts, reverses and braking. This places high demands on engines and their maintenance. Let's look at the specifics of crane electrical equipment.
Features of crane motors
- Intermittent duty (S3–S5) with frequent starts.
- Reverses and braking - high dynamic loads.
- Special series (MTF, MTH) with wound rotor.
- Presence of a braking system.
Typical faults
| Problem | Cause |
|---|---|
| Overheating of the winding | Frequent starts, overload |
| Wear of contact rings | Operating mode |
| Bearing wear | Vibration, loads |
| Brake failure | Wear of linings |
Maintenance
- Monitoring the condition of brushes and slip rings.
- Checking and adjustment brakes.
- Measurement of insulation resistance.
- Control of bearings and lubrication.
Crane motors require higher grade insulation due to heating during frequent starts. When repair of crane motors heat-resistant materials are used. The safety of the crane depends on the health of the engine and brake, so regular diagnostics is important.
