Abstract
Abstract A heavy-duty moving system including a sled, two sets of removable heavy-duty caster wheels (FIG. 1) and a lever arm assembly (FIG. 1A) for moving heavy equipment, for example, the ''''XEROX'''' copy machines of the 2400 series. The sled is slid under the machine (FIG. 3) and then raised at one end by the lever assembly (FIG. 4), one set of caster wheels then being laterally inserted and locked into the sled (FIG. 5). The opposite end of the sled is raised and the second set of caster wheels inserted and locked into the sled (FIG. 6). Upon lowering, the equipment is then ready for transportation (FIG. 7).

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
131 words
A method of providing a heavy load having a substantial portion of its bottom area offset from the surface on which it rests with means for easy locomotion comprising the following steps: a. providing an extended base member and at least one wheeled carriage member structurally separate and apart from said base member; b. moving only said extended base member under the heavy load at the offset portion; c. jacking up one part of said base member until the heavy load rests at least in part on said base member; and d. inserting said carriage member under said base member and placing said carriage member and said base member in juxtaposition so that said base member will rest on said carriage member when said part of said base member is unjacked.
Claim 2
Independent Claim
131 words
A method of providing a heavy load having a substantial portion of its bottom area offset from the surface on which it rests with means for easy locomotion comprising the following steps: a. providing an extended base member and at least one wheeled carriage member structurally separate and apart from said base member; b. moving only said extended base member under the heavy load at the offset portion; c. jacking up one part of said base member until the heavy load rests at least in part on said base member; and d. inserting said carriage member under said base member and placing said carriage member and said base member in juxtaposition so that said base member will rest on said carriage member when said part of said base member is unjacked.
Claim 3
Dependent Claim
123 words
The method of claim 1 wherein there is further included after step ''''d'''' the steps of: e. jacking up a second part of said base member until the heavy load rests at least in part on said second part of said base member; f. inserting at least a second carriage member under said base member and placinG said second carriage member and said second part of said base member in juxtaposition so that said base member will rest on said second carriage member when said second part of said base member is unjacked; and g. unjacking said parts of said base member after the carriage members have been inserted; whereby the heavy load through said base member now rides on said carriage members.
Claim 4
Dependent Claim
26 words
The method of claim 2 wherein in steps ''''d'''' and ''''f'''' there is further included the step of locking said carriage means to said base member.
Claim 5
Dependent Claim
24 words
The method of claim 2 wherein in step ''''b'''' the base member is moved under the heavy equipment by means of a sliding action.
Claim 6
Dependent Claim
30 words
The method of claim 2 wherein in steps ''''c'''' and ''''e'''' said parts of said base member are jacked up by means of a lever arm of the first order.
Claim 7
Dependent Claim
34 words
The method of claim 1 wherein said base member includes a channel for receiving said carriage member, said carriage member being inserted under said base member by sliding said carriage member into said channel.
Claim 8
Dependent Claim
36 words
The method of claim 2 wherein in steps ''''d'''' and ''''f'''' the carriage member is inserted in a direction lateral to the jacking, that is, in a direction perpendicular to the plane of the jacking direction.
Claim 9
Dependent Claim
41 words
The method of claim 7 wherein said base member is elongated and includes two lateral channels on its underside for receiving said carriage members, said carriage members being inserted under said base member by sliding said carriage members into said channels.
Claim 10
Dependent Claim
14 words
The method of claim 8 wherein said carriage means are locked into said channels.
Claim 11
Dependent Claim
26 words
The method of claim 9 wherein said locking is done automatically by spring-loaded bolts attached to said sled means fitting into holes in said carriage means.
Claim 12
Dependent Claim
34 words
The method of claim 1 wherein in step ''''d'''' the carriage member is inserted in a direction lateral to the jacking, that is, in a direction perpendicular to the plane of the jacking direction.
Claim 13
Independent Claim
165 words
The method of putting heavy-duty moving equipment on a piece of heavy equipment having generally rectangularly shaped bases comprising the steps of: a. sliding sled means under the piece of heavy equipment so that it extends from end to end of the piece of heavy equipment; b. inserting a first-order lever under a first end of said sled means and raising up said sled means so that at least a part of the heavy equipment now rests on said sled means; c. placing laterally a set of rolling elements under said sled means at the end which is raised; d. inserting a first-order lever under the other end of said sled means so that the heavy equipment fully rests on said sled means; e. placing laterally a second set of rolling elements under said sled means at the second raised end; and f. lowering said sled means so that the heavy equipment and sled means are now fully carried by said sets of rolling elements.
Claim 14
Independent Claim
165 words
The method of putting heavy-duty moving equipment on a piece of heavy equipment having generally rectangularly shaped bases comprising the steps of: a. sliding sled means under the piece of heavy equipment so that it extends from end to end of the piece of heavy equipment; b. inserting a first-order lever under a first end of said sled means and raising up said sled means so that at least a part of the heavy equipment now rests on said sled means; c. placing laterally a set of rolling elements under said sled means at the end which is raised; d. inserting a first-order lever under the other end of said sled means so that the heavy equipment fully rests on said sled means; e. placing laterally a second set of rolling elements under said sled means at the second raised end; and f. lowering said sled means so that the heavy equipment and sled means are now fully carried by said sets of rolling elements.
Claim 15
Dependent Claim
62 words
The method of claim 12 wherein between steps ''''c'''' and ''''d'''' said first end is lowered so that at least part of the heavy equipment and the end of said sled means is partially carried by said first set of rolling elements, and said first-order lever arm is removed and is used to raise up the other end of said sled means.
Claim 16
Dependent Claim
29 words
The method of claim 13 wherein said sled means is provided with its own wheels and said sled means is slid under the heavy equipment by rolling it under.
Claim 17
Dependent Claim
37 words
The method of claim 14 where said sled means is provided with two lateral channel guides, said set of rolling elements being laterally placed under said sled means by inserting the rolling elements into said channel guides.
Claim 18
Dependent Claim
22 words
The method of claim 15 wherein said sets of rolling elements are locked into said channel guides when they are centrally located.
Claim 19
Dependent Claim
26 words
The method of claim 16 wherein said locking is done automatically by a spring-loaded bolt mating with a hole in each said set of rolling elements.
