Operators need to spend a lot of time when selecting workstations suitable for bridge legs; and multi-stations are not conducive to workstation management. The number of workstations put into use every day is relatively fixed. The increase in the specifications of workstations will inevitably cause a large number of workstations to accumulate.

The design of the folding column 2 of the present application saves space when vacant work station equipment is stored in a transport box. The original work station equipment had a maximum stacking height of two layers during transportation due to the height limit of the vehicle. Now, through the folding column 2, the maximum stacking height of the vacant work station equipment during transportation is four layers, and the single transportation cost is reduced by 33% compared with the original. When stored in the factory's internal warehouse, the original work station equipment had a maximum stacking height of four layers due to the height limit of the forklift and the warehouse.
