HOIST • TROLLEY • LONG-TRAVEL
Crane Motors – Hoist & Travel Duty
IE2/IE3 efficiency, S3/S4 duty, brake-integrated, encoder & VFD-ready. Builder estimates kW and budget price for your duty and speed.
- IEC 60034
- F/H Insulation
- IP55–IP65
- PTC/PT100 & Encoder
Duty per FEM 9.751 (M4–M6). Estimator is budgetary; final selection after gearbox & thermal check.
- IEC 60034
- IE2 / IE3
- Brake-integrated
- VFD-Ready
Hoist Duty
High starting torque, S3/S4 duty, DC disc brake with rectifier, optional encoder.
Travel Drives
Trolley / long-travel motors for smooth acceleration with VFD or 2-speed pole-changing.
Protection
IP55–IP65, Class F/H, PTC/PT100, space heater, tropicalization & anti-condensation.
Integration
Fits geared motors/gearboxes, keyed or splined shaft, terminal boxes rotatable.
Sized for Your Duty, Not Just Nameplate
- Thermal margin: checks ED%, starts/hour and ambient to avoid overheating.
- Speed control: VFD-ready windings & insulation or 2-speed pole-changing options.
- Brake sizing: brake torque ≥ 1.8× rated torque with manual release.
- Environment: IP55–IP65 seals and heaters for humidity & dust.
