A stair climber moving system (FIGS. 1-2) for moving a load up flights of stairs FIGS. 4A-4H) which includes a basic tractor unit, a load mounting platform attached to the tractor which allows the load to be shifted longitudinally with respect to the tractor during use, and a collapsible dolly (FIGS. 3A-3D) permitting load changes from horizontal (3B) and inclined (3D) positions. The collapsible dolly includes a fixed horizontal bottom platform supported by five sets of caster wheels. A collapsible load bearing platform is mounted and supported on the fixed bottom platform by a fixed center vertical strut member through a hinge connection. At opposed ends of the collapsible load bearing platform are auxiliary, end, support members, one fixed and the other collapsible, the latter of which is spring biased in a normally vertical, supporting disposition. The load bearing platform is collapsible, i. e. put in an inclined disposition by means of moving said collapsible auxiliary end support out against the force of the spring, allowing the load bearing platform to rotate about its hinged connection.

A heavy duty moving system including a base sled having two sets of integral, drop-leaf, heavy duty caster wheels (FIG. 1) and a lever arm assembly (FIG. 6) for moving heavy equipment, for example, the "XEROX" copy machines of the 2400 series. The sled is slid under the machine (FIG. 8) and then raised at one end by the lever arm assembly (FIG. 9), after which one set of integral, drop-leaf caster wheels are lowered into position and locked. The opposite end of the sled is jacked up and the second set of integral, drop-leaf caster wheels are lowered and locked into position after which the lever arm assembly is removed. The machine then rests on the sled and its caster wheels and is ready for transportation. The machine is taken off the moving system in the opposite manner.
