Crane motors of the MTF and MTH series are specially designed for heavy-duty lifting applications. Let's look at their features.
What are they created for?
Crane engines are designed for intermittent operation (S3–S5) with frequent starts, reverses and braking - something that would kill a regular engine. They have an increased starting torque and are resistant to overloads.
Differences between MTF and MTH
| Series | Feature |
|---|---|
| MTF | Class F insulation |
| MTH | Class H insulation (more heat-resistant) |
MTH with class H insulation can withstand higher temperatures, which is important for particularly intensive work.
Design features
- Slip ring rotorwith slip rings - for starting control.
- Increased starting torque.
- Resistance to frequent startsand overloads.
- Often complete with a brake.
Repair features
Crane motors require qualified repairs: restoration of slip rings, rewinding with insulation of the required class, balancing. Repair of crane engines takes into account their heavy duty operation. The condition is assessed by diagnostics.
