Document Type and Number:
Japanese Patent JPH10157978
Kind Code:

Abstract:

To prevent mud or the like from sticking to a handle at running time on the muddy ground or the like, and prevent an increase of total width of an upper part turn unit by the amount with the handle provided.

A lifting handle 12 provided in an outer side surface of a turn frame 5 is set so that a space B' between a lower end part of a grip part 12B thereof and an upper surface of a crawler belt 2A obtains a space C (B'≥C) or more between a lower surface of the turn frame 5 and the upper surface of the crawler belt 2A, and the handle grip part 12B is constituted so as to retract to a side of a driver's room 7 by the dimension E from outside a handrail 9 protruded to an outer side surface of the driver's room 7. In this way, a large space can be held between the grip part 12B and the upper surface of the crawler belt 2A of a lower part running unit 2, for instance, at running time or the like in the muddy ground, mud sticking to the crawler belt 2A of a lower part running unit 2 can be prevented from sticking to the grip part 12B. By the amount providing the lifting handle 12, a total width of an upper part turn unit 3 can be prevented from increasing, for instance, good workability in a narrow work site can be maintained.
