2 is a guide rail extending along the longitudinal direction of the frame 2 and guiding the step chain 9;
On this guide rail 12, the front wheel roller shaft 1
The front wheel roller 20 supported by 5 is movable.

The work cart 1 has a predetermined number of front wheel roller shafts 15.
An operating switch 3 is mounted and fixed on the top, and this operating switch 3 is connected to the
It is connected to an operation panel 5 of a low-speed motor 11 temporarily installed within the upper horizontal portion 2a of the frame 2. This low-speed motor 11 is for driving the work cart 1, and is connected to the drive mechanism of the escalator via a temporary belt or pulley. Therefore, by operating the operation switch 3, the low speed motor 11 is started to drive the drive sprocket 7, and the step chain 9 and the front wheel roller shaft 15 are activated.
At the same time, the work cart 1 can be moved along the guide rail 12. Here, front wheel roller shaft 1
As the means for fixing the work cart 1 to the second
As shown in the figure, a structure is adopted in which a claw 17 fixed to a work floor 16 of a work cart 1 is engaged with a front wheel roller shaft 15. Further, on both sides of the work floor 16, pairs of columns 18a, 18b, and 18c are erected on the front and rear ends and in the middle thereof (only one side is shown in the figure), and between the columns 18a and 18b, respectively. A handrail 19 is horizontally suspended, and safety fences 21a and 21b are attached as side plates between pillars 18a and 18c and between 18c and 18b, respectively. These safety fences 21a, 21
