A lower mast is attached to a base having fork pockets, and is pivotal between vertical and horizontal positions. A lower mast brace assembly has a receiver configured to receive the lower mast as it is moved into the generally vertical position, and to retain it there. An upper mast having a hoist at its upper end slides into the lower mast. The upper mast has a dogleg that offsets the hoist forward of the centerline of the lower mast. A hook is attached to the lower mast brace assembly near the receiver. The hinge, the lower mast brace assembly, the dogleg of the upper mast, and the hook are arranged so that the hoist may be used to pull the mast from the horizontal position to the vertical position. A combination limit switch, buffer, and vertical shutoff switch may be attached to the upper end of the upper mast.
