Abstract: Lift apparatus is adapted for raising and lowering portable elevators and the like and includes both a power lift mechanism and an alternative manual lift mechanism. It also includes an upper limit stop for limiting the height to which the power lift mechanism can raise the elevator and a tie-down limit stop for tying the raised end of the elevator to an anchoring object for safety in addition to prohibiting the power lift mechanism from operating when the elevator lift apparatus which includes a cable for drawing a front frame member toward a rear frame member to effect raising the rear end of a grain elevator is provided on one end with a power driven winch for drawing the cable to effect lifting. A hydraulic fluid flow circuit is provided to supply the hydraulic motor with fluid, said circuit having an alternative one-way directional flow route for bypassing the hydraulic motor on the power lift mechanism.

Abstract: Lift apparatus is adapted for raising and lowering portable grain elevators and the like and includes both a power lift mechanism and an alternative manual lift mechanism. It also includes an upper limit stop for limiting the height to which the power lift mechanism can raise the elevator and a tie-down limit stop for tying the raised end of the elevator to an anchoring object for safety in addition to prohibiting the power lift mechanism from operating when the elevator is so anchored. In the disclosed embodiment, an elevator lift apparatus which includes a cable for drawing a front frame member toward a rear frame member to effect raising the rear end of a grain elevator is provided on one end with a power driven winch for drawing the cable to effect lifting, and it is also provided on its opposite end with a manual winch for also drawing the cable to effect lifting.
