Abstract
Fall restraint equipment comprising a mobile access unit having a mobile platform portion, a ladder portion, and a cage portion. The components of the fall restraint equipment are formed from butterflying, lasering, cutting, bending, and/or stamping continuous pieces of tubular and sheet metal. The components of the mobile access unit are modular and include adapters of varying height that cause the mobile access unit to exhibit varying height. Also, the mobile access unit is adaptable so that it can roll in a first direction of orientation of the ladder or a second direction perpendicular to the first direction.
Claims16
A mobile access unit comprising:
- a base portion having a rectangular platform with connection features on four sides thereof;
- said rectangular platform having a fixed perimeter defining the four sides thereof, and at least one support surface spanning an area inside the perimeter;
- a ladder assembly mounted to said base portion in a slant with respect to said base portion;
- and
- a pair of wheel assemblies selectively connectable to said base portion via said connection features on a first pair of opposite sides of said base portion and a second pair of opposite sides of said base portion such that wheels of the pair of wheel assemblies will rotate about a common axis;
- a third wheel assembly selectively connectable to a first side of said base portion near a middle of the first side of said base portion when said pair of wheel assemblies are connected to said first pair of opposite sides and selectively connectable to a second side of said base portion near a middle of the second side of said base portion when said pair of wheel assemblies are connected to said second pair of opposite sides, said first side and said second side being orthogonal to each other;
- wherein said first side of said base portion is not one of the first pair of opposite sides and the second side of the base portion is not one of the second pair of opposite sides;
- such that said base portion can roll in a first direction of orientation of said ladder or a second direction perpendicular to said first direction utilizing said pair of wheel assemblies and said third wheel assembly.
