VEHICLE FOR HIGH LIFT WORK

摘要

PROBLEM TO BE SOLVED: To provide an arrangement which allows the treads of crawler traveling elements to variably project from right and left side portions. SOLUTION: This vehicle for high lift work includes a body and an operator's cabin part 1 at the end of a boom 2 pivotally attached to the top of the body in such a manner as to freely rise and fall. In this case, a pair of right and left crawler traveling elements 5 are disposed on the body and the treads of the right and left crawler traveling elements 5 can be freely projected to right and left side portions in symmetry with respect to a frame 6, to enable setting in small width while movement and setting in a large width during operations.
