The electric hoist of climbing frame can lift dozens of group cranes at the same time. It is a kind of slow lifting hoist and can reach the designated position accurately. At the same time, only one external wall scaffold needs to be set up in high-rise buildings, and the use of the vertical hoist as a hoist is controlled by the electric control box, which can meet the lifting requirements of the external wall scaffold of the cabinet frame structure and the shear structure. How to hang the 5-30t electric hoist? The first point is to use it together with the attached scaffold. First, hang the electric hoist vertically so that the upper and lower hooks are respectively fixed in the prefabricated parts of the scaffold. The hanging cardan shaft is connected and fixed with the wall attached support through the middle waist hole. The second step electric hoist is composed of top lifting point connection piece, top fixing device, universal suspension shaft, G80 lifting chain, transmission wheel, hook and other parts. The third step should pay attention to check the chain at any time for twisting, stacking and other phenomena. In daily construction, g80 lifting chain shall be suspended vertically, the chain and the lower hook shall not be twisted and reversed, the guide wheel and lifting chain shall be meshed correctly, otherwise, the lifting sprocket, guide wheel and lifting chain will be jammed (damaged), so that the electric hoist of climbing frame can not work normally. The fourth step requires correct connection of power supply, ground wire connection, positive and negative rotation. At the same time, check and test whether the operation of the hanging block of the climbing frame is flexible. Finally, check whether the upper and lower hooks of the electric hoist on the climbing frame are fastened. If there is no problem, the operation can be started
