Abstract:
1. A multi-capacity vehicle lift system comprising: a load platform having a vehicle support surface defining a plane; an expandable linkage assembly mechanically coupled to said load platform to facilitate raising said load platform above a base surface, said linkage expandable between a fully collapsed position and an expanded position wherein the load platform is raised above said base surface; and an actuator assembly coupled to said expandable linkage, said actuator assembly having an adjustable length driving member configured to transition between a retracted length and an extended length, said actuator assembly positionable at a plurality of different starting angles relative to said base surface while the expandable linkage is in the fully collapsed position and said driving member is at said retracted length, wherein each of the different starting angles enables said driving member to apply a different vertical force component to said expandable linkage during extension from said retracted length, and wherein each of said different starting angles is associated with a respectively different lift capacity for elevating said load platform.
