Weight lifting simulator apparatus (1 ) includes a primary pneumatic cylinder (14) providing the principal resistance for simulating weight lifting exercise with at least one secondary cylinder (30) in free fluid interconnection with the primary cylinder (14) whereby constant and balanced loading is achieved, with provisions for dynamic simulation of weight inertia effect, and control thereof, as in lifting a real weight. The primary (14) and the secondary (30) cylinders are associated with a guideway (4), the primary cylinder (14) being fixed to the guideway (4) and the secondary cylinder (30) being slidable relative to the guideway (4) and pivotable relative to the piston rod (18) of the primary cylinder (14). Variation of the securement position of the primary cylinder (14) on the guideway (4) is available and valving (42) is provided in the fluid interconnection.
Appareil (1) de simulation de levage de poids comprenant un vérin primaire (14) pneumatique produisant la résistance principale simulant l'exercice de levage de poids, au moins un vérin secondaire (30) en interconnexion de fluide libre avec le vérin primaire (14) afin d'obtenir une charge constante et équilibrée, des moyens pour simuler dynamiquement les effets d'inertie du poids et un moyen de commande desdits moyens, comme dans le levage d'un poids réel. Les vérins primaire (14) et secondaire (30) sont associés à un rail (4), le vérin primaire (14) étant fixé au rail (4) et le vérin secondaire (30) pouvant glisser par rapport au rail (4) et pouvant pivoter par rapport à la tige (18) de piston du vérin primaire (14). Une modification de la position de fixation du vérin primaire (14) sur le rail (4) est possible et un clapet (42) est disposé dans l'interconnexion de fluide.
