Vibration damping means for the roll-over protection canopy of a heavy vehicle

摘要

Vibration damping means for a mounting post of a roll-over protection canopy of a heavy vehicle such as a tractor, earth mover, or the like. A hollow square post has slightly concave walls and slides over an upright square mounting stub on the vehicle, to which it is secured by a bolt which impales the post and the stub. A reduced upper end portion of the stub receives a vibration damping member which is in the form of a hollow square. The member has rounded corners which fit snugly in the corners of the post, and the span across opposite faces of the member is less than the internal width of the post so as not to bind in the post.
