US Patent 10544019 Scissor lift with hydraulic pulling cylinder

A lift device configured to lift an object includes a stationary base, a lift assembly, a support assembly, and a lift mechanism. The lift assembly is movably coupled to the base, and the support assembly is movably coupled to the lift assembly. The support assembly is configured to support the object. The lift mechanism has an adjustable length. The lift mechanism is coupled to the base and to the lift assembly such that decreasing the length of the lift mechanism moves the support assembly upwardly and increasing the length of the lift mechanism moves the support assembly downwardly.
