US 2008/0302601 A1 · LIFT ASSEMBLY

Abstract

A portable lift assembly that moves between a retracted position and an extended position when operatively connected with a drive mechanism. The portable lift assembly comprises a first telescoping assembly, a second telescoping assembly, a support assembly and a pulley assembly. The first telescoping assembly has a first stationary leg and a first movable leg, the first movable leg being movable with respect to the first stationary leg. The second telescoping assembly has a second stationary leg and a second movable leg. The second movable leg is movable with respect to the second stationary leg, wherein the support assembly slidably engages with the second movable leg. The pulley assembly operatively connects to the first telescoping assembly and to the support assembly wherein the pulley assembly, when activated by the drive mechanism, simultaneously moves the first movable leg and the support assembly from the retracted position to the extended position to raise the platform to an elevated position.
