Claim:
1. A fall arrest system, comprising: a base, said base including a base support structure, a plurality of wheels attached to the support structure, a plurality of adjustable anchors pivotably attached to and extendable from the base support structure each having a ground-contacting pad thereon, a towing tongue extending from one end of the base support structure, a power source; a four-bar linkage operatively connected to said base support structure, which operates as one of the bars in said linkage, said four-bar linkage further including an upper longitudinal tube and a lower longitudinal tube, each pivotably coupled to the base support structure and extending generally in parallel with one another, and where the opposite ends of the longitudinal tube pieces are also pivotably connected to a cantilever linkage member; and a cantilevered beam extending from the cantilever linkage member, said cantilevered beam having a mechanism for attaching a flexible support to the free end thereof to arrest the fall of a worker attached to the arrest system via the flexible support; wherein when the system is in a first position for storage or transport the upper longitudinal tube, lower longitudinal tube and cantilever beam are generally parallel with one another and when the system is in a second position for fall arrest of the worker the cantilever beam extends approximately perpendicular to the generally parallel upper longitudinal tube and lower longitudinal tube.
