A moving system (1/101) made up of a number of separable but intergratable parts and platform sections (10-90/110-190), including an elastically biased, pivoted, integral end ramp section (10) which can be pivoted and moved down to allow the load (e.g. a copier with "convenience casters") to be rolled up onto platform sections (40 & 50/140 & 150) for movement from one location to another. The moving system also includes the following additional parts or sections-in one embodiment or the other a supplemental ramp piece (120) which is usually stored on the exterior side of the ramp end section (110) when not in use but is connectable to the end of the main ramp section to extend the effective ramping distance; a protective pad (30/130) for the ramp end section; a first platform section (40/140); a second platform section (50/150), as well as an auxiliary, pivoting, intermediate braking support member (160); a handle end section (70/170); an extendible handle (80/180); and an interconnecting, ninety (90 DEG ) degree, leg section (90/190). The platform sections include four supporting caster wheels (20/142& 152), the two at the handle end being lockable into a straight disposition or alternatively unlocked to allow them to be free-wheeling. Foot operated mechanisms (21, 55, 59 & 62) are provided for quickly and easily latching and unlatching different parts. A pair of elastic "bungee" cord sections or springs (17) bias the end ramp section in both its vertical disposition and its ramping disposition by having its effective ends off-set with respect to the pivoting hinge for the ramp. The ramp section also includes an effective braking/immobilizing support (15/115).
