Title:
SELF-TRAVEL CONSTRUCTION MACHINE
Document Type and Number:
Japanese Patent JPS6185284
Kind Code:
A
Abstract:
PURPOSE:To improve the travel-through force and the stability on unlevelled land by constructing such that many wheels fixed to the chassis are driven entirely at anytime. CONSTITUTION:The axle tube 17 for the front and rear wheels 9a, 9b and 12a, 12b fixed to the chassis 1 is secured through fixing tool 18 to the chassis 1. While the axle for the intermediate wheels 10a, 10b, 11a, 11b is supported by the piston rod 16 of hydraulic cylinder 15 mounted on the chassis 1 to be liftable/lowerable. At the neutral position of hydraulic cylinder 15, the intermediate wheels 10a and 10b, 11a and 11b will ground entirely at same height with other wheels while at the lowering position of hydraulic cylinder, only the intermediate wheel will ground. Consequently, all wheels fixed to the chassis will travel in full wheel drive system at anytime.
