Abstract
Abstract This invention relates to a transporter having an adjustable platform, the transporter comprising a platform, a wheel bogie, means for supporting the rear end of the platform on the wheel bogie wherein said supporting means further comprises means restricting movement of the platform relative to the bogie in the generally horizontal direction and allowing movement of the platform relative to the wheel bogie in the generally vertical direction, and means for connecting the platform to the bogie, said connecting means providing generally vertical adjustment of the platform relative to the bogie in a selected manner. Also included is a front section pivotally connected to the front of the platform for rotation about a transverse axis of the platform, means connected between the pivotal section and platform for adjusting the vertical height of the front end of the platform relative to the ground, and further comprising means for connecting the front section to a truck for towing the transporter.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
128 words
An adjustable transporter comprising a platform, a wheel bogie, means for supporting the rear end of the platform on the wheel bogie, said supporting means comprising sliding guide means restricting both transverse and longitudinal movement of the platform relative to the bogie and allowing movement of the platform relative to the wheel bogie in the generally vertical direction, and means for connecting the platform to the bogie, said connecting means providing generAlly vertical adjustment of the platform relative to the bogie in a selected manner and providing a rigid connection against vertical movement of the platform relative to the bogie for each selected position of vertical adjustment, the transporter further comprising means for connecting the front end of the transporter to a towing vehicle for towing the transporter.
Claim 2
Dependent Claim
128 words
An adjustable transporter comprising a platform, a wheel bogie, means for supporting the rear end of the platform on the wheel bogie, said supporting means comprising sliding guide means restricting both transverse and longitudinal movement of the platform relative to the bogie and allowing movement of the platform relative to the wheel bogie in the generally vertical direction, and means for connecting the platform to the bogie, said connecting means providing generAlly vertical adjustment of the platform relative to the bogie in a selected manner and providing a rigid connection against vertical movement of the platform relative to the bogie for each selected position of vertical adjustment, the transporter further comprising means for connecting the front end of the transporter to a towing vehicle for towing the transporter.
Claim 3
Dependent Claim
66 words
The transporter of claim 1 further comprising a front section pivotally connected to the front of the platform for rotation about a transverse axis of the platform, the towing vehicle connecting means being located near the front of the pivotal section, and means connected between the pivotal section and platform for adjusting the vertical height of the front end of the platform relative to the ground.
Claim 4
Dependent Claim
18 words
The transporter of claim 2 wherein the means for connecting the platform to the bogie are hydraulic means.
Claim 5
Dependent Claim
88 words
The transporter of claim 3 wherein the pivotal section further comprises arms extending along the sides of the platform, the arms being pivotally connected to said sides for pivotal movement of the pivotal section about a transverse axis of the platform, the pivotal section having a raised portion higher than the front of the platform, and further comprising extensible actuating means connected between the raised portion of the pivotal section and the platform at a location on the platform spaced from the pivotal axis of the pivotal section.
Claim 6
Dependent Claim
87 words
The transporter of claim 3 wherein the pivotal section further comprises arms extending along the sides of the platform, the arms being pivotally connected to said sides for pivotal movement of the pivotal section about a transverse axis of the platform, the pivotal section having a portion below the front of the platform, and further comprising extensible actuating means being connected between the lower portion of the pivotal section and the platform at a location on the platform spaced from the pivotal axis of the pivotal section.
Claim 7
Dependent Claim
65 words
The transporter of claim 1 wherein the platform mounting means further comprises guide blocks mounted to the bogie, and vertical guide rails secured to the platform in close spaced relation to the guide blocks, the blocks moving vertically within the rails as the vertical height of the platform is adjusted, but closely restricting the transverse and longitudinal movement of the platform relative to the bogie.
Claim 8
Dependent Claim
38 words
The transporter of claim 6 wherein the side surfaces of the guide blocks taper inwardly toward their tops to provide relief to prevent interference between the bogie and platform where the platform is tilted about its longitudinal axes.
Claim 9
Dependent Claim
52 words
The transporter of claim 1 wherein the bogie connecting means are hydraulic cylinders and there is at least one of said cylinders at the front and rear ends of each side of the bogie, the cylinders on one side of the bogie being operable independently of the cylinders on the other side.
Claim 10
Dependent Claim
14 words
The transporter of claim 1 wherein the platform is extensible in the longitudinal direction.
Claim 11
Dependent Claim
14 words
The transporter of claim 1 wherein the platform is extensible in the transverse direction.
Claim 12
Dependent Claim
32 words
The transporter of claim 1 including jacks mounted about the perimeter of the platform and having a vertically adjustable support means for raising a load carried on the transporter off the platform.
Claim 13
Dependent Claim
36 words
The transporter of claim 1 including a jack stand at the front end of the transporter, the jack stand being adjustable to support the front end of the transporter in the absence of a towing vehicle.
Claim 14
Dependent Claim
15 words
The transporter of claim 1 wherein the platform and bogie are of tubular frame construction.
Claim 15
Dependent Claim
146 words
An adjustable transporter comprising a platform, a wheel bogie having a rigid frame structure suspended on a plurality of wheels, means for supporting the rear end of the platform on the wheel bogie, said supporting means comprising sliding guide means restricting both transverse and longitudinal movement of the platform relative to the bogie and allowing movement oF the platform relative to the wheel bogie in the generally vertical direction, a plurality of extensible actuating means connecting the platform to the bogie, actuation of said extensible actuating means in a selected manner providing generally vertical adjustment of the platform relative to the bogie in a selected manner and providing a rigid connection against vertical movement of the platform relative to the bogie for each selected position of vertical adjustment, and means for connecting the front end of the transporter to a towing vehicle for towing the transporter.
Claim 16
Dependent Claim
146 words
An adjustable transporter comprising a platform, a wheel bogie having a rigid frame structure suspended on a plurality of wheels, means for supporting the rear end of the platform on the wheel bogie, said supporting means comprising sliding guide means restricting both transverse and longitudinal movement of the platform relative to the bogie and allowing movement oF the platform relative to the wheel bogie in the generally vertical direction, a plurality of extensible actuating means connecting the platform to the bogie, actuation of said extensible actuating means in a selected manner providing generally vertical adjustment of the platform relative to the bogie in a selected manner and providing a rigid connection against vertical movement of the platform relative to the bogie for each selected position of vertical adjustment, and means for connecting the front end of the transporter to a towing vehicle for towing the transporter.
