Gear Motor for Crane and Hoist

Application:​

• Travelling mechanism of overhead crane, gantry crane, jib crane, end carriage and trolley crab

• European-style wire rope electric hoist & chain electric hoist

• Material handling, workshop, port, metallurgy, mining, construction and warehouse lifting equipment

• Other heavy-duty conveying machinery requiring frequent start-stop and braking

Parameters:​

• Power range: 0.18 kW ~ 15 kW

• Power supply: 3-phase AC 380V / 50Hz (VFD version available for variable speed 5–100Hz)

• Duty cycle: S3 40% / 60% ED for heavy crane working class

• Insulation class: F (155°C)

• Protection class: IP54 / IP55

• Gear type: Parallel shaft helical gear

• Brake type: Electromagnetic fail-safe brake (power-off braking)

• Mounting: Flange mounted / foot mounted

• Working temperature: -20℃ ~ +40℃

Features:​

• Highly integrated compact structure: Motor, gearbox and brake combined as one unit, small footprint, saves installation space and reduces overall hoist headroom.

• Fail-safe electromagnetic brake: Automatically engages when power cuts off to prevent load slipping, safe for frequent start, stop and reverse operation.

• Smooth & low-noise operation: Precision carburized helical gears, less gear impact, stable running and low vibration.

• Strong load capacity & long service life: Hardened gear pair, high-strength output shaft, adapted to heavy intermittent lifting duty.

• Easy installation & maintenance: Modular design, fewer connecting parts, convenient assembly and inspection.

• Optional variable frequency version: Soft start & soft stop, precise positioning, reduces mechanical impact on crane structure.
