Braking equipment for aerial work vehicles

摘要

PROBLEM TO BE SOLVED: To provide brake equipment for high-lift work vehicle capable of enhancing work efficiency by reducing the workload for actuating an auxiliary brake means.SOLUTION: Brake equipment comprises: a brake pedal 71 capable of being operated by stepping down; a master cylinder 73 generating a brake actuation force by actuating in response to a stepping-down operation of the brake pedal 71; the brakes 74, 75 braking the tire wheels 3 by the brake actuation force; and auxiliary working brake equipment 80 retaining the braking state of the tire wheels 3 by retaining the brake actuation force. When a brake lock-resetting switch 92 provided on a work bench is operated, the master cylinder 73 and auxiliary working brake equipment 80 are actuated in addition to the step-down operation of a brake pedal 71 to retain the braking state of the tire wheels 3 by the brakes 74, 75.SELECTED DRAWING: Figure 3
