Support wheel anti-extension device, WINTERHOFF

The fuse consists of a spring and a cover plate. Installation is done by simply fitting it onto the support wheel bracket without tools. The spring is hinged on the handle of the holder and is held in a vertical position by a pressure plate. The lower end of the spring is bent upwards. If the support roller extends spontaneously during driving, e.g. due to insufficient tightening of the upper handle or excessive vibrations, the support roller tube is caught by the lower spring hook after a few centimetres of extension. This minimises the risk of losing or destroying the inner extending part of the support wheel during driving.consists of a spring and a cover plate.
