<p>In order to operate with maximum efficiency and safety, this device comprises two tubular assemblies which bear a jaw-holder block and can slide one within the other. An interlock system is arranged between the tubular assemblies and the jaw-holder block in order to control the sliding of the inner tubular assembly by that of the outer tubular assembly. The tire push member borne by the inner tubular assembly can push the sidewall of the tire back only when the fixed and movable jaws strongly clamp the flange of the rim. This device is preferably operated by a pneumatic impact wrench.</p> |
