In a lift for watercraft, a load translation mechanism balances load upon the actuator throughout the raising and lowering of watercraft, thereby greatly reducing load spikes. Embodiments of the improved lift employing an over-center locking mechanism further employ an elastic stop means to reduce jarring of the apparatus when it locks in the over-center position. In some preferred embodiments, adjustable telescoping booms allow the user to adjust the height of the lifted watercraft above the base of the lift.

Sur un appareil de levage pour embarcations marines, un mécanisme de translation de charge équilibre ladite charge sur l'actionneur pendant l'élévation ou l'abaissement de l'embarcation, ce qui permet une forte réduction des pointes de charge. Des versions améliorées de cet appareil de levage, qui sont munies d'un mécanisme de verrouillage en décentrage, ont également recours à un dispositif d'arrêt élastique pour réduire les secousses de l'appareil lorsqu'il se verrouille à la position de décentrage. Dans des versions préférées, des flèches télescopiques réglables permettent à l'utilisateur de régler la hauteur de levage de l'embarcation au-dessus de la base de l'appareil de levage.
