Abstract
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.
Claims5
A safety device of a working vehicle comprising:
- front wheels and rear wheels rotatably provided on the front and rear, and right and left of a vehicle body respectively;
- a steering device to make each of the front wheels and the rear wheels turn to change a travel direction of the vehicle;
- a drive device to rotationally drive at least either of the front wheels and the rear wheels to make the vehicle travel;
- a brake device to brake the rotation of the front wheels and the rear wheels;
- a steering operation device being operated by an operator to steer the front wheels and the rear wheels;
- a travel operation device being operated by an operator to make the vehicle travel by the drive device;
- and
- a travel controller to control working of the steering device based on a steering operation of the steering operation device and to control working of the drive device and the brake device based on a travel operation of the travel operation device,
- wherein when any travel operation by the travel operation device is not performed, the travel controller performs braking the front wheels and the rear wheels by the brake device, and
- wherein when a travel operation by the travel operation device is performed, the travel controller releases the braking by the brake device and makes the drive device work the vehicle to travel based on the travel operation,
- the safety device comprising:
- a vehicle body inclination angle detector to detect an inclination angle of the vehicle body,
- wherein 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.
