Abstract
Abstract A vehicle primarily designed to transport a large load, such as a modular home. The vehicle comprises a substantially U-shaped frame to partially enclose the load and load engaging means movably connected to the frame in such a manner as to enable adjustment in a horizontal direction to correspond to the specific size of the load and to enable movement in a vertical direction to lift the load.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
164 words
A vehicle of the type designed to transport large loads such as modular homes said vehicle comprising: a frame in which the load is supported, load engaging means including a plurality of track units connected to said frame, adjusting means to adjust the size of said load engaging means such that it corresponds to the size of the load; positioning means connected to said frame such that said load engaging means may be vertically positioned relative to said frame, said adjusting means comprising at least one link member pivotally interconnected between said positioning means and each track unit, a shaft movably arranged along each of said track units, a piston and cylinder assembly disposed relative to each of said shafts on each of said track units such that said link member moves each track unit relative to one another upon movement of said shaft, whereby the position of each of said track units may be varied by actuation of said piston and cylinder assembly.
Claim 2
Dependent Claim
164 words
A vehicle of the type designed to transport large loads such as modular homes said vehicle comprising: a frame in which the load is supported, load engaging means including a plurality of track units connected to said frame, adjusting means to adjust the size of said load engaging means such that it corresponds to the size of the load; positioning means connected to said frame such that said load engaging means may be vertically positioned relative to said frame, said adjusting means comprising at least one link member pivotally interconnected between said positioning means and each track unit, a shaft movably arranged along each of said track units, a piston and cylinder assembly disposed relative to each of said shafts on each of said track units such that said link member moves each track unit relative to one another upon movement of said shaft, whereby the position of each of said track units may be varied by actuation of said piston and cylinder assembly.
Claim 3
Dependent Claim
54 words
A vehicle as in claim 1 wherein said frame is substantially U-shaped and includes two longitudinally extending legs, each of said track units extending along the length of one of said legs, said adjusting means interconnected to both said frame and said tracks units so as to regulate the distance between said track units.
Claim 4
Dependent Claim
44 words
A vehicle as in claim 1 wherein said positioning means comprises a plurality of lift arms movably interconnected between said frame and said load engaging means, whereby the vertical position of the load may be varied to accomplish loading and transporting of said load.
Claim 5
Dependent Claim
76 words
A vehicle as in claim 3 wherein said frame is substantially U-shaped and includes a pair of longitudinally extending legs arranged in substantially parallel relation to one another, and a plurality of lift arms pivotally mounted along each of said legs; each of said lift arms connected to one of said track units in spaced relation to the remaining of said lift arms, whereby rotation of said lift arms causes vertical movement of said track units.
Claim 6
Dependent Claim
63 words
A vehicle as in claim 3 further comprising means to rotate said lift arms relative to said frame, said means including at least one winch mounted on said frame, a cable and pulley assembly interconnecting said lift arms to said winch such that the driving of said winch rotates said lift arms whereby the load engaging means is moved in a vertical direction.
Claim 7
Dependent Claim
78 words
A vehicle as in claim 1 wherein said adjustment mean includes at least one shaft movably disposed on each of said track units, at least one cylinder and piston assembly associated with each track unit, each of said cylinders fixedly secured to one of said track units, each of said pistons fixedly secured to one of said shafts such that relative movement between said piston and said cylinder causes movement of said track units relative to said frame.
Claim 8
Dependent Claim
135 words
A vehicle as in claim 1 wherein said frame iNcludes at least two longitudinally extending legs arranged in spaced parallel relation to one another; said positioning means comprising a plurality of lift arms interconnected between each of said legs and its associated track unit, whereby movement of said lift arms causes vertical positioning of said track units; an adjusting means comprising a shaft movably connected to each track unit, a plurality of link members interconnecting said lift arms to said associated track unit, at least one piston and cylinder arrangement cooperating with each track unit, said piston being fixedly secured to said shaft and said cylinder being fixedly secured to the cooperating track unit, whereby movement of said piston relative to said cylinder causes movement of said track unit toward and away from one another.
