Abstract
A scissor lift has a pair of leg assemblies pivotally connected to a base. Relative movement between the legs and the base is opposed by spring assemblies that may be selectively connected to a carriage to vary the bias on the legs. A cam member secured to the leg acts on the carriage to modify the motion between the leg and the carriage to maintain a uniform vertical spring rate.
