Composition of Electric Hoist
Motor: Hoist Motor is an taper type rotor motor with braking,it is made by Nanjing special motor factory,it is of the best quality motors, it has bigger torque, so it can be adapted to moving frequently.
Trolley: It is assembled and has running wheels. Herein, the runner wheels are mounted on top-class sealed ball bearings.
Gear Box: Hoist Gear Box has specially treated gears for high wear resistance. Each Geared Shaft assembly is supported on ball or roller bearings , to ensure smooth, low-friction operation.
Wire Rope: Hoisting rope comply with the exporting ISO standards. The leading rope taken by the Drum, does not slip sideways when slack. The factor of safety, on the nominal breaking strength of the rope is six.
Rope Drum: Grooved Drum, seamless pipe of adequate length to be wounded in one layer and to provide proper support for the rope to minimize abrasive wear is provided. Drum Shaft resolves on Ball Bearings for ensuring smooth running.
Electric control system: Model CD1 and MD1 is composed of the contactor box,controlling switch,cut-off limiter.the working voltage of controlling switch is 380V,36V or 24V(safety voltage).
Rope Guide: Rope Guide is in two halves, ensuring easy accessibility. It encircles the Drum completely so that the rope may not uncoil even when the Hoist is in unloaded condition.
Hook: The Hook Block is tested to 150 % of full load before assembly. The rope sheaves are fully guarded with protective steel casting .
