A locking mechanism limits the motion of a vehicle cab that swings down on the vehicle chassis to rest on a floating bracket, where the floating bracket is supported by shock absorbers mounted to a chassis. The mechanism prevents upward movement of the floating bracket and thereby prevents upward swing of the cab from the chassis. The locking mechanism includes a flat arm fixed to the floating bracket and a fulcrum member fixed to the flat arm. The fulcrum member pivotally mounts a swing arm having a projection at one end. The mechanism is in a locking condition when the projection engages a mounting bracket fixed to the chassis. At different times when the cab swings down to the floating bracket, the cab's alignment with the chassis varies. The locking mechanism has features which allow it to adjust three-dimensionally to variations in this alignment.
