Abstract
A stabilizer is provided for the mast of a lift truck for resisting torsional forces applied to the elevating system as the lift truck changes attitude. The stabilizer includes a pair of 'A' frames with the apexes of the frames pivotally secured together. The spaced legs of the frames are connected, in the case of the one 'A' frame, to the respective uprights of the mast and, in the case of the other 'A' frame, to the vehicle chassis or fender. The connections between the 'A' frames, the mast and the vehicle chassis are such that the forward and rearward tilt of the mast is not restricted, but twisting forces between the mast and the chassis are restrained. The 'A' frames also provide a protective guard for the operator's cab and, because of the openings through the frames, the frames do not restrict the visibility of the operator.
