Working principle of electric hoist single beam crane

Electric hoist single girder crane refers to the electric hoist as lifting mechanism of the single-beam crane , its working principle is simple, Xiao Bian here to introduce under the electric hoist single girder crane works.

Electric hoist single-beam cranes are divided into three parts: cart operating mechanism, trolley operating mechanism and lifting mechanism (electric hoist). The lifting mechanism is responsible for the lifting and lowering of the weight in the vertical direction, and the trolley operating mechanism is responsible for the left and right movement of the lifting mechanism and the weight in the direction parallel to the main beam. The cart operating mechanism runs on the crane beam and is responsible for the movement of the single-beam crane in the entire space of the workshop. The three parts of the crane work together to complete the handling of heavy objects at any position in the three-dimensional space.

When the single-girder crane is working, operate the remote control to lower the hook to a suitable position, tie up the heavy objects, operate the remote control, and the hook rises a small distance, make sure that the heavy objects are bound without problems, and then continue to rise to a suitable height, and then Operate the cart to move to the target location, operate the cart to accurately move the heavy object to the sky above the target location, and then operate the electric hoist to accurately place the heavy object to the target location to complete the work.

When operating a single-girder crane, it is necessary to abide by the safe operation regulations and resolutely implement the "ten no cranes".

1) The command signal is unknown or the command is not suspended in violation of regulations;

2) Heavy objects are overloaded, and the weight is unclear.

3) The work is not tightly tied or skewed;

4) There are people or floating objects on the hanging objects.

5) The safety device fails to hang;

6) The workpiece is buried in the ground without hanging;

7) The light is dark and the line of sight is unclear;

8) Do not hang angular objects without protective measures;

9) Pull any object obliquely without hanging;

10) The ladle of steel and hot metal is too full.

After the operation is completed, the hook must be raised to the specified height to avoid other operations that affect the ground.
