Abstract A tractor type vehicle in which frame parts along the sides of the vehicle have upstanding arms at the sides of the driver''s position to protect the driver if the vehicle capsizes. The frame parts are resiliently mounted on the vehicle and fluid operable bolts are provided responsive to fluid pressure to lock the frame parts to the vehicle. The vehicle may carry a loading implement with lift cylinders and a single pressure source is provided for actuating the bolts and the lift cylinders. A valve between the source and the bolts controls the bolts and another valve between the bolts and the lift cylinders provides for actuation of the lift cylinders only when the bolts are actuated.
