To prevent the doors of a tilting cab type vehicle swinging open inadvertently when the cab is in its tilted position, each door is provided with arrester means which are operative when the cab is tilted but disabled when the cab is in its normal position. The arrester means comprise a ratchet and pawl device, the pawl device being spring urged into engagement with the ratchet through the intermediary of a pivoted arm, the ratchet and pawl device and the arm being mounted on the cab adjacent to the respective door. An adjustable stop is mounted on the chassis of the vehicle and arranged to engage the arm when the cab is in its normal position so as to disengage the pawl from the ratchet. The ratchet may be afforded by a part secured to the door hinge, a part of the door hinge itself, or a check strap. |
