摘要： The safety device comprises a vehicle body inclination angle detector to detect an inclination angle of the vehicle body. In a vehicle body attitude in which the inclination angle of the vehicle body detected by the vehicle body inclination angle detector is less than a predetermined inclination angle, while any travel operation by the travel operation device is not performed, when a steering operation by the steering operation device is performed, the travel controller performs control to release braking the front wheels and the rear wheels by the brake device and to make the steering device turn the front wheels and the rear wheels in accordance with the steering operation.

摘要： A work vehicle steering control apparatus comprises a vehicle body (11), front wheels and rear wheels both of which can be steered respectively; a front-wheel steering cylinder (92) and a rear-wheel steering cylinder (94); a steering dial (72); a steering actuation controller (50); and a steering angle detector. The steering actuation controller (50) is configured in a manner such that when a steering operation is performed, and when the steering angles of one set of wheels are less than a predetermined angle (θ1), the controller (50) controls the steering actuator to steer only the one set of wheels in response to the directional-change steering operation. When the steering angles of the one set of wheels are equal to or more than the predetermined angle, the controller (50) controls the steering actuator to steer the other set of wheels in a direction opposite to steering direction.

摘要： In a vehicle with aerial work platform, while not receiving an operation instruction to move down the work platform from the rise and fall operating device, when moving down of the work platform is detected based on the detecting result of the rise and fall position detecting device, the rise and fall control device controls the first switching valve to switch so that the bottom-side oil chamber is connected to the hydraulic pump and controls the second switching valve to switch to the first state so as to make oil pressure in the bottom-side oil chamber be kept by the second switching valve and the check valve. Then, the rise and fall hydraulic cylinder is stopped to be contracted.

摘要： A steering control device for a vehicle with an aerial work platform 1 in the embodiment a traveling body capable of traveling with a steering wheel, a work platform 30 provided thereon, a steering dial 42, which is biased to be located at a neutral position in a non-operation status, a steering angle detector 62, a steering cylinder 17, and a controller 50 for controlling an operation of the steering cylinder 17. The controller 50 controls the steering cylinder 17 so that a steering angle of the steering wheel becomes a target steering angle corresponding to a steering position of the steering operation tool. As far as a steering angle of the steering wheel detected by the steering angle detector is kept within a predetermined angle range including a neutral steering angle, the steering control unit make a steering control to stop the steering actuator and to maintain the present steering angle of the steering wheel when the steering operation tool returns to the neutral position.
