Operating characteristics and operating procedures of hoist

Structural features

1,HoistIt consists of motor, hoist, frame, protective cover, etc.; adopts three-stage deceleration method and uses screw to drive, so the output torque is larger. The steel frame of the gate hoist overcomes the unevenness of civil construction to reduce the noise and vibration of the whole machine.

2. User-shaped long-time work motor, protection level ≥IP55. The stroke control organization adopts the principle of decimal counter, and the error of the control stroke is 0.5%. Torque protection control is the principle of protecting electrical appliances by touching the micro switch through the axial displacement of the worm.

3. The operation protection is simple, and can complete on-site and remote control operations.

Operating procedures

1. The construction unit of the project must install the hoist on a flat and solid foundation with good visibility. The fuselage and ground anchors must be strong. It is required that the center line of the gate hoist and the guide pulley should be straightly aligned, and the pitch pulley of the gate hoist is generally not less than 15 meters.

2. Before adjustment and construction, check the wire rope, clutch, brake, secure ratchet, transmission pulley, etc., to confirm that it is safe and reliable, and then operate. The wire rope must be arranged neatly on the drum, and at least three turns are required during operation. During construction, no one is allowed to cross the wire rope of the gate hoist to avoid accidents.

3. When lifting heavy objects and need to stay in the air, in addition to using the brake, the ratchet wheel should be used to securely secure it. During operation, do not leave the post without authorization.

4. Observe the signal of the commander during work. When the signal is unknown or may cause an accident, the operation should be suspended and the operation can only be continued after the situation is clarified.

industry. If there is a sudden power failure during operation, the knife should be opened immediately and the transported objects should be put down.
