double speed construction wirerope electric hoist 5ton machine

Model CD1 and MD1 wire rope electric hoist is small-sized lifting equipment, which can be mounted on single beam, bridge, gantry and gib cranes. With slight modification, it can also used as a winch. It is widely used in factories, mines, harbors, warehouse and shops, essential in raising working efficiency and improving working conditions.

Model CD1 electric hoist has only one normal speed, which can satisfy normal application. Model MD1 electric hoist provides two speeds, normal speed and low speed. At a low speed, It can do precise loading and unloading, mounding of sand box, maintenance of machine tool. Model MD1 electric hoist is more widely than model CD1.

Drawing :

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 2.4-3 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 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. The rope guides of our company is thicken and dilated, so that it is not easy to be damaged.
Hook	The Hook Block is tested to 150 % of full load before assembly.
Reducer	Thirdclass dead axel helica gear transmission structure is adopted,; gear and gear axel are made of heat treated alloy steel.
Safty divice	Fire stopper,overload limited device ,
Electric Hoist Control	1. Pendant and remote control 2. Easy, safe and Smooth operation 3. Waterproof , anti-fall
