Title (EN) IMPROVED DRUM FOR A MOTORIZED LIFTING/PULLING DEVICE
(FR) TAMBOUR AMÉLIORÉ POUR DISPOSITIF DE LEVAGE/TRACTION MOTORISÉ
Abstract:
(EN) An apparatus for providing reliable line spooling for hoists, winches, and other pulling and/or lifting devices is disclosed. In one embodiment, such an apparatus includes a motor and a drum rotated by the motor to draw in or let out a line from the drum. The drum includes a helical groove formed in an outer surface thereof to accommodate the line. A roller is provided to place pressure on the line against a groove in the drum. In certain embodiments, the drum comprises a groove which widens as it gets closer to the drum. In other embodiments, the groove is formed by sidewalls which are various shapes and dimensions allowing the line to be held in the groove.
(FR) La présente invention concerne un appareil permettant d'assurer un bobinage de câble fiable pour des grues, des treuils et autres dispositifs de traction et/ou de levage. Dans un mode de réalisation, un tel appareil comprend un moteur et un tambour entraîné en rotation par le moteur pour faire entrer un câble dans le tambour ou le faire sortir de celui-ci. Le tambour comprend une rainure hélicoïdale formée dans une de ses surfaces externes pour recevoir le câble. Un rouleau est prévu pour appliquer une pression sur le câble contre une rainure du tambour. Dans certains modes de réalisation, le tambour comprend une rainure qui s'élargit lorsqu'elle se rapproche du tambour. Dans d'autres modes de réalisation, la rainure est formée par des parois latérales qui ont diverses formes et dimensions permettant à la ligne d'être maintenue dans la rainure.
