Title (EN) TELESCOPING BOOM WEAR PAD IMPROVEMENTS
(FR) AMÉLIORATIONS APPORTÉES À UNE PLAQUE D'USURE DE BRAS TÉLESCOPIQUE
Abstract:
(EN) This disclosure relates to a wear button or pad for a telescoping boom of the type comprising at least an outer boom member comprising a threaded bore therethrough for the wear pad assembly, and an inner boom member that is slidable with respect to the outer boom member. In one form, the wear pad assembly comprises a wear pad and a base, a first of which comprises a generally cylindrical body comprising a curved external side surface comprising a screw thread via which this is threadably engageable in the threaded bore, and an internally tapered expandable collet, and the second of which comprises an externally and complementarily tapered mandrel portion, wherein in use, the externally threaded part is threadably engaged in the threaded bore and expanded therein by insertion of the externally and complementarily tapered mandrel portion in the expandable collet.
(FR) La présente invention concerne un bouton ou une plaque d'usure pour un bras télescopique du type comprenant au moins un élément de bras externe, comportant un alésage fileté à travers celui-ci pour l'ensemble plaque d'usure, et un élément de bras interne, qui peut coulisser par rapport à l'élément de de bras externe. Dans un mode de réalisation, l'ensemble plaque d'usure comporte une plaque d'usure et une base, dont la première comprend un corps généralement cylindrique comportant une surface latérale externe et incurvée comportant un filetage de vis par l'intermédiaire duquel celle-ci peut venir en prise par filetage dans l'alésage fileté, et un collet expansible et évasé intérieurement, et dont la seconde comprend une partie mandrin évasée de manière complémentaire et extérieure, en cours d'utilisation, la partie filetée extérieurement venant en prise par filetage dans l'alésage fileté et étant déployée à l'intérieur de celui-ci par l'insertion de la partie mandrin évasée de manière complémentaire et extérieure dans le collet expansible.
