Title:
GROUND WORKING DEVICE-LIFTING STRUCTURE OF WORKING VEHICLE
Document Type and Number:
Japanese Patent JP3078986
Kind Code:
B
Abstract:
PURPOSE: To obtain a ground working device-lifting structure facilitating a work for connecting the rear part of a link mechanism to a working mechanism placed on the surface of the ground by forcibly lifting the link mechanism, when a speed change device is operated on the side of a backward travel, and by forcibly not lifting the link mechanism, when the working device is not connected to the link mechanism.
CONSTITUTION: A control means for forward or backward operating an actuator 5 on the operation of a switch 17 is disposed, and set so that the actuator forcibly lifts the link mechanism 4, when a speed change device for travel is operated on the side of backward travel. Whether the working device 6 is connected to the link mechanism or not is detected with sensors 21, 22. When the working device is not connected, the link mechanism is forcibly not lifted with the actuator, and the frame can backward be moved in the state wherein the link mechanism is lowered.
