Portable multistage lifting machine

Abstract

A portable lifting machine is disclosed for lifting and transporting loads. The machine may include a base supporting a mast having a plurality of telescoping portions pivotally attached to the base for movement between vertical, angled, and stored positions. A load lifting assembly, including a lift support and a lifting mechanism such as a winch, may be operable to raise and lower the telescoping portions. A pair of base legs and a pair of outrigger legs may be pivotally coupled to the base to provide adjustable stability, with each leg positionable and lockable in multiple orientations. The base may include frame rails with wheels at opposite ends to permit rolling movement and forklift engagement. Dust shields and a mast hold-down mechanism may protect and secure the telescoping portions during use or transport. The lifting machine provides a compact, reconfigurable structure suitable for safe lifting in various environments.
