Linear cable engines

A tyre construction (8) specifically designed for linear cable engines which is such as to adequately grip the external surface of a cable (11) and to transfer load to the cable, particularly for small diameter (10-16mm, for example) cable. In one embodiment (Fig 3), the tyre has a solid zone (9) an...

More Information
Summary:A tyre construction (8) specifically designed for linear cable engines which is such as to adequately grip the external surface of a cable (11) and to transfer load to the cable, particularly for small diameter (10-16mm, for example) cable. In one embodiment (Fig 3), the tyre has a solid zone (9) and a pneumatic zone (10) whose radial depth d is predetermined by the cable diameter (D) for optimum performance, for example in the range D/4 to D/2. The solid zone (9) only permits partial deformation of the pneumatic zone (10) sufficient for cable gripping and then serves in the load transfer. The pneumatic zone (10) may be of the form of a low-profile tyre or be provided by voids/cells (21 - Fig 4) disposed adjacent the radially outermost region of the tyre.
