| 1 | Brief Introduction for wire rope eletric hoist | CD1 and MD1 series wire rope electric hoists are improved on basis of CD and MD series electric hoists. It has features of compact structure, light and handy, safe and reliable, most spare parts are general-duty, big single lift capacity, easy to maintain and etc. The above advantages make this wire rope electric hoist the most welcome and widely used light lifting equipment. This series wire rope electric hoist has two types, fixed type and trolley type. The fixed type are divided into A1, A2, A3, A4 four types, they can be installed on the frame directly. The trolley type can be moved can install on the rail. CD1 is single speed lifting equipment, while MD1 always have double lifting speed which is normal speed and slow speed. We mainly manufacture capacity 0.24-20t, lift height 3-30m series electric hoists; also we can design special electric hoists as your requirement. electric wire rope hoist |
| 2 | Electric Wire Rope Hoist Application | Trolley electric hoist can be installed with most cranes or hang on the joist steel girder, lift cargo in straight line or curve line; fixed electric hoist can be installed on fixed support and lift cargo with vertically or with different angles. electric wire rope hoist |
| 3 | Wire Rope Electric Hoist Operate Conditions | Working temperature: -25-+40 degree Work moisture: <85% Elevation: <1000m No fire, no explosive goods, no corrosion medium. Forbidden to lift melting metal, poisonous, explosive, flammable goods. The working duty is medium, when using when the working duty is level up, the rated lift capacity should be reduced accordingly (20% per level). electric wire rope hoist |
| 4 | Electric Hoist Hoisting /Lifting mechanism | Lifting motor drives rope drum rotating through coupling and hollow shaft of reducer, which makes the wire rope on the rope drum driving the hook unit up and down. If lift height is 6m, a claw coupling is used to link the motor shaft and input shaft of reducer. If lift height is or more than 9m, intermediate shaft and rigid coupling are added. If lift height is or more than 18m, a carriage is used to enhance the rigidity of intermediate shaft. electric wire rope hoist |
| 5 | Lifting motor on wire rope electric hoist | Lifting motor uses tapered rotor motor with strong staring torque to adapt frequent direct staring in the intermittent work.CD1 type hoist uses ZD type single speed motor and MD1 type hoist uses ZDS type double speed motor. The ratio of ZDS type motor's constant speed and slow speed is 10:1 |
| 6 | Speed reducer on electric wire rope hoist | Cap 0.25t hoist uses straight tooth planetary gear reducer and the rest are using helical gear three stage reducer. Gear and shaft are made by alloy steel and high carbon steel and through proper heat treatment to ensure its reliability and service life. Box body and cover is made of cast iron to ensure hoist's good damping performance and reliable sealing. |
| 7 | Rope Drum on hoist | Rope Drum is made of cast iron or seamless steel tube, using/with the help of spline transferring power. The sell of rope drum is welded with steel plate. Rope drum is the central heart of a hoist. The upper side is linked with traveling mechanism through equalizing beam. Both ends are connected with lifting brake and motor respectively. The lower side works together with hook through wire rope. Up front of the cover, limiting stopper guide-rod and heavy punch stop block are installed. electric wire rope hoist |
| 8 | Electric device on hoist | The electric device of CD1 MD1 model hoist consists of electric control box (No electric control box, if the lift capacity is 0.25t), button switch, Limiting stopper, connecting wires and so on. The normal operating voltage of button switch is 380V or 36V. Pressing the correct button can control the hoist through controlling on and off of the relay in the control box, according to the direction symbols on the button switch. electric wire rope hoist |
