Construction Lift operation

1.Open the total power supply of the ground fence power box.
2. Carry loaders and materials according to the rated capacity indicated on the cage nameplate.
3. Close the fence door, cage door and top door.
4. Turn the handle of the total limit switch on the drive plate to the middle position.
5. Pull the handle of the operating switch to the necessary running direction (indicated by the arrow) and the cage can be started.
6. When the cage reaches the required floor, release the handle, the handle points to the zero position and the cage stops running.
7.When installing and dismantling the cage lift or for maintenance, please screw the plus section/running switch of the cage top operation panel into the plus section position and operate at the cage top.
8. When manipulating the high-speed construction hoist past the variable speed collision block without variable speed, you must immediately place the manual variable speed at the low speed level or zero position, stop and check whether the limit switch is normal and the installation position of the variable speed collision block is correct. During normal operation, care should also be taken to control the operating speed. It can only run at high speed when the travel is far enough, that is, the handle can reach a greater angle. When the cage reaches its destination, put the handle on the low speed gear and reduce the speed to stop to ensure the correct position. When the floor is not high and the travel is not far, the operator must control the running speed to low or medium speed according to the actual situation to ensure safety and accurate position.
