Upside down chain electric hoist is a slow speed chain electric hoist, 5 tons to 30 tons of upside down hoist can simultaneously carry dozens of simultaneous lifting and group cranes, and the speed is low and balanced, and it can reach the designated position without error. Usually, a high-rise building with dozens or dozens of floors only needs an external wall scaffold. When using it, it can be controlled by the electric control box by using the upside down hoist as the hoist, which can meet the requirements of the cabinet structure and the shear structure. Construction requirements. So how to hang that upside down hoist on a climbing frame? Next, let's explain to you in detail. First of all, you need to understand that the climbing frame upside down hoist is composed of the top lifting point connector, the top fixing device, the lifting chain, the transmission wheel, the universal suspension shaft, and the hook. It needs to be used in synchronization with the attached scaffold. First, hang the electric hoist vertically. The upper and lower hooks need to be fixed in the prefabricated parts of the scaffold. The hanging universal shaft is connected to the wall support on the wall through the middle waist hole. Then check the chains for twisting, knotting, accumulation, etc. The lifting chain must be vertically suspended and straightened, the chain and the lower hook must not be twisted and twisted, the sprocket, guide wheel, and lifting chain should be properly engaged, otherwise the lifting sprocket, guide wheel and lifting chain will be damaged. The inverted hoist does not work properly. Finally, connect the power supply, the ground wire, and rotate it forward and backward one time, check whether the test climbing frame upside down hoist is flexible; check whether the upper and lower hooks are hung firmly, and check that you can start the operation.
