It is provided with the auxiliary work platform 20 which an operator can stand on the uppermost stage, and the center column <the rotation shaft 22 of this invention> is in the moving space 12 which is a clearance gap between the steps of the main work platform 10. Position so that it can move within the length of the main workbench. By doing so, the main work table 10 and the auxiliary work table 20 can be relatively changed in height, length, rotation angle. The operator according to the present invention is to lift and move each workbench by repeating the action of moving the main workbench standing on the auxiliary workbench, moving the foot to the main workbench, and then moving straight and rotating while standing on the main workbench and moving the auxiliary workbench. It is possible to walk and to rotate at the same time.

The movement of the main workbench and the auxiliary workbench in order to reduce worker fatigue by not using power to move the workbench and preventing the worker from bending the back is as follows.

1. When moving the main work station, the operator stands on the footrest of the auxiliary work station and raises the railing of the main work station. At this time, the integrated main scaffold 16 is raised from the ground by raising the railing. The main workbench is lifted and the road moves straight to the moving space. At this time, if the direction can be rotated by rotating the amount of movement of the left and right hands holding the handrail. If you move as much as you want, put it down.

2. The operator moves to the footrest of the main workbench. Lifting the auxiliary handle 24 raises the integrated auxiliary work platform and moves it into the main work platform as much as the main work platform has moved.

3. Repeat steps 1 and 2 above.

Through the present invention, the operator moves the mobile aerial platform on which the worker lifts himself up without outside help on the working platform of the mobile aerial platform, while allowing the mobile aerial platform to move freely without moving in the straight direction, but falling. It becomes easier to utilize the aerial platform equipped with a railing as a prevention mechanism, thereby improving the efficiency of aerial operation and eliminating the falling elements caused by the use of conventional aerial work equipment using ladders.

-How the main workbench walks and turns

  A worker standing on the main scaffold 16 of the main work platform 10 to lift the auxiliary work platform 20 higher than an obstacle height and then lowering it horizontally;

  The operator stands on the auxiliary scaffold 26 of the auxiliary work platform 20 to lift the main work platform 10 higher than the obstacle height and put it down after rotation and horizontal movement; Here's how you can create a walking aerial platform:

  The present invention implements the object of the present invention when the operator lifts the main pole 11 and the auxiliary pillar 21 of the work stand on which the worker stands on the workbench, and goes straight while rotating. To this end, a worker stands on the main scaffold 16 or the auxiliary scaffold 26 to change the relative position of the auxiliary work platform 20 and the main work platform 10 in the moving space 12 in the UD direction. , Axial change (HM direction) or rotation (RT direction).

  This allows the main workbench and the auxiliary workbench to move over an obstacle as a person walks by repeatedly moving in the axial direction while changing the angle relatively.

  Lifting and rotating and moving the auxiliary work platform on the main footrest 16 implements the auxiliary work platform moving step, and lifting and rotating and moving the main workbench on the auxiliary footrest 26 implements the main work platform moving step.

  Thus, in order for the main workbench and the auxiliary workbench to walk and rotate as illustrated in FIG. 7, the height of the upper rotary shaft space G2 and the lower rotary shaft space G1 must be greater than the maximum height H of the obstacle OS. However, if this height is too large, the height of the auxiliary scaffold 26 of the auxiliary work platform is higher than the height of the main scaffold 16, which makes it difficult for the operator to move up and down, and the structural stability is impaired when moving the main work platform on the auxiliary work platform. The height should be below the knee of the person.

  When working for a long time in one place, it is recommended to fold the rotating shaft and the auxiliary footrest of the auxiliary workbench and fold them only when moving them.
