Abstract
A lift device includes a base, a platform that is repositionable relative to the base between a fully raised position and a fully lowered position, and a scissor assembly coupling the base to the platform. The scissor assembly includes a scissor layer including a first scissor arm pivotally coupled to a second scissor arm. The first scissor arm is configured to rotate relative to the second scissor arm about a middle axis that extends laterally. A pulley is coupled to the first scissor arm. A tensile member is wrapped around the pulley and coupled to the second scissor arm. An actuator is configured to vary a working length of the tensile member such that the first scissor arm rotates relative to the second scissor arm to move the platform relative to the base.
