TURNING CONTROL MECHANISM FOR TRAVELING WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a turning control mechanism for a traveling working machine to perform smooth switching of a manual brake operation accompanied by turning of a machine body and an autobrake device without needing a troublesome operation and to provide an operating device to approximately equalize the return feelings of a control lever even when the control lever is returned to a neutral position from either of switch operation positions on one side or the other side. SOLUTION: When an auxiliary shift lever 1 is switched from a low speed side L to a high speed side H in a state that autobrake devices 4a and 4b are automatically switched to OFF. In a state that the auxiliary shift lever 1 is switched to the high speed side H, an operation to switch the auto brake devices 4a and 4b from OFF to ON is blocked. In a state that the auxiliary shift lever 1 is switched to the low speed side L, the operation to switch the autobrake devices 4a and 4b from ON to OFF is enabled.
