SELF-PROPELLED DEVICE FOR CASING PRESS-IN DEVICE

摘要

PROBLEM TO BE SOLVED: To smoothly move a transfer device for a casing press-in device by the self-propelled device and easily transfer it to a narrow work site. SOLUTION: In the easing press-in device equipped with a easing press-in means on a base frame, forward and rearward wheel units equipped with two right and left wheels in a chassis are detachably connected and it is so constituted that the base frame can be supported without grounding it by these four wheels when the units are connected. Auxiliary wheels are provided in the chassis so as to be vertically movable in at least one wheel unit. The auxiliary wheel is put in a positional relation in which the wheel unit can be transferably supported by the two right and left wheels and the auxiliary wheel when the auxiliary wheel is lowered. Further, a drive device rotating the two right and left wheels is installed on the chassis.
