  • Lift machine
    Patent number: 7866445
    Abstract: A lift machine comprises a base, a support for supporting a load above the base, a lift actuator operatively connected between the base and the support for raising and lowering the support relative to the base, and a support stabilization mechanism operatively connected between the base and the support for stabilizing the support relative to the base during raising and lowering of the support by the lift actuator. The support stabilization mechanism comprises a pair of opposed linkages, with each of the pair of opposed linkages having a lower torque tube link and an upper torque tube link. The lower torque tube link has a torque tube operatively pivoted to the base. The upper torque tube link has a torque tube operatively pivoted to the support.
    Type: Grant
