Hoist

For all types of large-scale water supply and drainage, water conservancy and hydropower projects. Used to control all types of large and medium-sized cast iron gate and steel gate lift to open and close the purpose.

Structural features:

1, hoist including motor, hoist, rack, protective cover and other components; using three deceleration mode, with the country to pay the transmission, the output torque greater. Hoist supporting steel frame to overcome the civil construction is not smooth, in order to reduce machine noise and vibration.

2, the use of outdoor long-term work of the motor system, protection class ≥ IP155. The stroke control mechanism adopts the decimal counter principle, the error of the control stroke is 0.5%. Torque protection control is generated by the axial displacement of the worm touch micro switch, to protect the electrical principle.

3, operation and maintenance is simple, can achieve on-site and remote control operation.

Hoist safety operating procedures are as follows:

1. Engineering construction units, to hoist should be installed in the formation of solid, good vision on the foundation above the fuselage and the anchor must be solid. Requirements Hoist and guide pulley centerline should be vertical alignment, hoist distance pulley generally should not be less than 15 meters.

2. Before the adjustment work, should check the wire rope, clutch, brake, insurance ratchet, drive pulley, etc., to determine safe and reliable, before operation. The wire rope must be neatly arranged on the reel and must be retained for a minimum of three turns. In the operation, not allowed to cross the hoist rope to prevent accidents.

3. In the lifting of heavy objects need to stay in the air, in addition to the use of brakes, and the use of ratchet insurance card. Operation, is strictly prohibited to leave the post.

4. Work to obey the commander of the signal, the signal is unknown or may cause an accident, it should suspend operation, to be clarified before continuing operations. Sudden power outage in the operation, should immediately pull open the knife, and the delivery of objects down.

Load test method for hoist

1, hoist operators must grasp the hoist structure, performance and operation methods, and have some mechanical knowledge to ensure the normal operation of the machine.

2, before the operation, a comprehensive inspection of the hoist, a part of the lubrication is good, whether the loose bolts.

3, when the hoist operation, the operator shall not leave the scene and found the problem immediately shut down.

4, the maintenance of the machine, you must remove the load.

5, in use, the need to inject oil from the oil hole at any time, we must always keep enough oil, the screw should be regularly cleaned grease, coated with new oil to prevent corrosion.
