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, a scissor assembly coupling the base to the platform, and a booster. The scissor assembly includes a scissor layer including a first scissor arm pivotally coupled to a second scissor arm, a pulley coupled to the scissor layer, a tensile member wrapped around the pulley, and an actuator 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. A booster is positioned to engage a portion of the tensile member and apply an upward force on the scissor assembly when the platform is in the fully lowered position.
