Three basic forms of electric hoists used in climbing frames

The current power lifting equipment for climbing frames is mainly electric hoist lifting, hydraulic lifting, and reducer lengthened screw lifting. Climbing frames, a type of external protective frame, are unique to China and can be lifted and lowered according to the load-bearing requirements during exterior wall decoration. The Electric Hoist used in the climbing frame is the DHP type climbing frame electric hoist. The three basic forms of this electric hoist used in the climbing frame are as follows:

Front-mounted electric hoist: In this case, a front-mounted climbing frame hoist is required. This use state requires that after each lift of the frame, the climbing frame hoist needs to be moved one floor high and the chain extended, which requires 3 steps at the same time. It takes more than 100 workers to operate together, and each operation takes 15 minutes even if it is smooth. The labor intensity of the workers increases. At the same time, because the load control system used is a tension sensor, the signal line of the tension sensor is easily damaged during the movement of the electric hoist.

2. The electric hoist is hung on the frame: When the electric hoist is hung inside the frame, a pulley and a sufficiently long steel wire rope need to be installed at the bottom of the frame. The strength of the mounting point of the frame needs to be increased, because this approach forms a single row of the frame. Stress can easily cause deformation of the frame guide rails. If a steel wire rope is used to lift the frame, the wire rope and the pulley are constantly rubbing and bending, requiring staff to frequently check the condition of the wire rope, which increases labor and instability factors.

3. Electric hoist hanging upside down: In this case, an upside-down climbing frame hoist is required. When the electric hoist is hung upside down, the length of the chain must be increased, and a mechanism for adjusting the tightness of the chain must be provided. After the electric hoist chain is tensioned, it must be ensured that the three hanging points of the upper, lower and attached wall supports are in a straight line. Once dirt enters the joint between the sprocket and the chain during use, it will cause the chain to get stuck or bite, cause the chain to break, and pose a safety hazard.
