Double Rail Wire rope Electric Hoist Trolley

1.Used on double girder crane
2.Strong hoist winch
3.Durable wire rope,hoist winch

4.Locate in crane hometown 

This is light and medium crane machinery, which can be fixed on double girder, bridge crane, portal crane and hanger crane. It is often used in factories, mines, work shops  etc., it can be used longer than the common hoist, which is the necessary machinery to raise labor productivity and improve working conditions.

Motor: Hoist Motor is a 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, the Maximum torque is 2.**3 times than the rated torque.

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 ropes comply with the exporting 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 hoist 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 apparatus controlling system: Model CD1 and MD1 hoist is composed of the contactor box, controlling switch, cut-off limiter, the working voltage of controlling switch is **0V,*6V or *4V(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. The rope guides of our company is thickened and dilated, so that it is not easy to be damaged.

Hook:The Hook Block is tested to **0 % of full load before assembly. The rope sheaves are fully guarded with protective steel casting. All sheaves rotate on ball bearing the pulley is thicken and dilated than domestic common pulley.

Higher Security and Reliability                                                                                                                      

1. Brake and clutch ensure the safety under any circumstance,no slip under load

2. IP*5 of hoist frame and brake ensures the optimal corrosion resistance under harsh environment.

3. Up and down limit switch ensures the safe operation of the hook on the top and bottom position. 

4. Low voltage contactor ensures the safe and reliable operation.
