A vehicle for underground mine shafts includes a body having a cabin located in a front section of a vehicle with an entry to the cabin located at the front of the vehicle, a door at the entry, a sensor for sensing when the door is open and control circuitry which is connected to the sensor. The vehicle also includes vehicle brakes to activate the vehicle brakes when the sensor senses that the door is open, a pair of tracks on either side of the cabin, a driving means for driving the tracks, a steering means for steering the body, and a suspension system including a torsion bar suspension arrangement which permits torsion bars of the vehicle to be located just above the level of track wheels of the vehicle. The torsion bar suspension arrangement has a torsion bar receiving means for applying torsion to the torsion bars and the torsion adjusting means includes engagement means being capable of orientation at a predetermined angle with respect to a vertical axis for engaging the torsion bar receiving means and a member having a channel formed therein for receipt of the engagement means. The torsion adjusting means is arranged to urge the torsion bar receiving means to a predetermined orientation.
