electric hoist

Electric hoist is a special lifting equipment installed on overhead cranes and gantry cranes. Electric hoist has the characteristics of small size, light weight, simple operation, and convenient use, and is used in industrial and mining enterprises, warehouses, docks, and other places. Electric hoists are essential machinery for improving labor efficiency and working conditions. The commonly used models of electric hoists are CD type and MD type.

electric hoist details

Brief Introduction of CD1/MD1 Electric Hoist

CD1 electric hoist has only normal speed,which can satisfy the general working requirement.

MD1 electric hoist has one more hoisting motor and one slow speed actuating device, which

make the model have two speeds.When it works slowly,it can satisfy the precise task such as precise working of loading or unloading, stand to break-in.

Safety is the most important issue for crane. To ensure the safety,the following safety devices are equiped in the electric hoist.

· Crane traveling limit switch

· Weight overload protection device

· Lifting height limit device

· Voltage lower protection function

· Phase sequence protection function

· Emergency stop function

· Rain cover for outside hoist, driving units, electrical cubicle

· Warming indicator, flashing lights and warming sound

· Wireless infra-detector for anti-collusion

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 .

Testing: All our Hoists are tested on 125 % thus assuring safe working load and is issued with a test certificate.
