How to replace electric hoist in electric single beam crane

Prepare climbing equipment, such as aerial work vehicles, scaffolding, etc. The height of the electric hoist of hoisting machinery is generally about 8 meters, and it is necessary to rely on climbing equipment for repair operations. Prepare 2 electric hoists, 2 lifting belts, wrenches, screwdrivers, and 2 sets of safety belts. After the installation personnel board the climbing equipment, they should fasten the safety belt and hang it in a secure place at each step. Turn off the power of the lifting equipment and remove all control lines of the electric hoist power cord to ensure that there is no need to worry when the hoist is lowered. The electric hoists of two electric single-beam cranes are suspended on both sides of the crane beam. The lifting points of the electric hoist must be firm and reliable, and can accept the weight of the electric hoist. Use two electric hoists to pull the original electric hoist from both sides until the hoist wheel leaves the I-steel tread. The two electric hoists are mainly used to maintain the balance of the electric hoist and facilitate disassembly. Loosen the screws at both ends of the axle of the trolley's hanging plate to separate the trolley's hanging plate from both sides. The electric hoists on both sides of the crane slowly lower the electric hoist of the electric single-beam crane until the crane is completely separated from the main beam. One of the electric hoists is completely unstressed. Remove the electric hoist, because an electric hoist can accept the weight of the electric hoist. For the remaining electric single-beam crane, the electric hoist has been placed on the ground. The primary purpose of using the electric hoist is to increase the power.

The installation procedure of the new electric hoist is opposite to the disassembly procedure. The electric single-beam suspension crane is a more practical type of crane on the market. As a large-scale equipment, if you do not pay attention to it in operation, it may cause accidents. Today, we will talk about the matters needing attention in the use of electric single-girder suspension bridge cranes.
Instructions for use. Before the electric single-beam suspension crane is used, it is necessary to walk around all the organizations in a no-load state, and then use it after all the devices are normal. The lifting weight of the bridge crane shall not exceed the extra weight of the single beam. When lifting objects, it is necessary to be in a straight position, and it is strictly forbidden to drag heavy objects with mobile electric single-girder cranes and manual monorail trolleys. Please perform other operation safety matters in accordance with relevant regulations.

Adjustment and maintenance. Check the main beam, the longitudinal organization of the trolley, and whether the connecting bolts of the manual monorail trolley are loose or broken, and deal with them in time. The pre-camber of the main girder is checked every year, and the reasons for the unqualified are analyzed and corrected in time. The adjustment and maintenance of the chain hoist shall be carried out according to the product operation manual. The metal structure of the crane can be painted every 3-5 years according to the last painting. The replacement of wearing parts such as wheels, gears, hooks, chains, etc. shall be performed in accordance with relevant regulations.
