Double girder crane precautions during the use

Double girder overhead crane is lifting the transport of modern industrial production and production process to achieve brake mechanization and automation of important tools and equipment. Double girder Light duty electric winchs in the indoor and outdoor industrial and mining, iron and steel industry, railways, ports and logistics flow and other departments and establishments have been widely used.
Double girder cranes stop Precautions
1, after the job is completed, the crane open to designated locations: one end of the car to open the cab, hook rises, all the control panel to "zero", cut off the power and wipe clean and keep clean.
2, good operating records and shift work shift. Double girder crane use surface cracks will appear, there are a variety of reasons

1, the load force can not change the direction of the back and forth: double girder crane lifting process, moving back and forth due to heavy attack has changed, especially in the severe load condition, the formation of discontinuity average beam, the beam will attack crack form life began double girder crane lowered.
2, wind can affect double girder electric hoist: When using double beam crane outside after midnight, the wind blowing through the inevitably large wind start, double girder cranes will attack shaking phenomenon, the appearance will attack cracks.
