Abstract

1502778 Elevator propelling arrangements J M FISKE and D P H ROGERS 10 March 1976 [10 Dec 1974] 53346/74 Heading B8L A scissor lift actuating linkage comprises scissor members B, C, pivotally interconnected and actuable by a ram E through a pair of link arms G, F, which move differentially upon ram motion to provide an approximately constant mechanical advantage on the linkage as it elevates a load platform D. With the body of the ram E pivoted to a base-plate A, the rod of the ram is pivotally connected at or adjacent a pivotal connection between the link arms G, F, the other ends of the link arms being pivotally connected one to each of the scissor members B. C. In the lowered position of the lift, the link arms G, F form a Vee with the apex thereof at the lower end at or adjacent the connection with the retracted ram which is substantially horizontal. Upon extension of the ram, a couple is initially applied to the scissor members through the link arms, the arm F acting downwardly and the arm G acting upwardly, the geometry of ram load application changing with elevation of the platform D. A torque tube H connects the arms F of a parallel pair of actuating linkages for raising a single platform.
