Abstract
Abstract An elongated vehicle supporting pallet structure is provided and includes opposite side longitudinally arranged crawler track assemblies for support of the pallet structure from a soft ground surface. The pallet structure includes at least one pair of opposite side sets of rotatably supported transverse rollers with each set of rollers including a pair of rollers spaced apart longitudinally of the pallet structure and defining an upwardly opening wheel cradling recess therebetween for cradling the lower peripheral portions of an associated vehicle drive wheel therein with the drive wheel supported from and disposed in driving engagement with the rollers. A drive train drivingly connects at least one roller of each set of rollers to the corresponding crawler track assembly and each of the crawler track assemblies includes an independently operable brake assembly. The pallet structure includes upper surface portions for supporting a wheeled vehicle therefrom including a pair of opposite side drive wheel assemblies driven from a differential assembly and with the drive wheel assemblies of the wheeled vehicle supportively cradled and driven by the corresponding set of pallet assembly rollers. The brake assemblies include hydraulic cylinder actuators each operatively connected to the corresponding brake assembly by means of a flexible hydraulic hose or line for portability of the actuators and to enable the latter to be supported in the operator''s cab of a wheeled vehicle supported from the pallet structure. Also, the hydraulic cylinder actuators for the brake assemblies are provided with foot treadle actuated operator portions.

Claim 1
Independent Claim
206 words
An elongated vehicle pallet including opposite side longitudinally arranged crawler track assemblies for support of said pallet from a soft ground surface, said pallet including at least one pair of opposite side sets of journaled transverse rollers with each set of rollers including a pair of transverse rollers spaced apart longitudinally of said pallet and defining an upwardly opening cradle recess for cradling the lower peripheral portions of an associated drive wheel therein with said drive wheel supported from and disposed in driving engagement with said rollers, means drivingly connecting at least one roller of each set of rollers to the corresponding crawler track assembly, said crawler track assemblies each having an independently operable brake assembly operatively associated therewith, said pallet including upper surface portions adapted to support a wheeled vehicle therefrom including a pair of opposite side drive wheel assemblies driven from a differential assembly and with said drive wheel assemblies cradled by said sets of rollers and, said brake assemblies including hydraulic cylinder actuators each operatively connected to the corresponding brake assembly by means of a flexible hydraulic hose for portability of said actuators and to enable the latter to be supported in the operator''s cab of a wheeled vehicle supported on said pallet.
Claim 2
Dependent Claim
206 words
An elongated vehicle pallet including opposite side longitudinally arranged crawler track assemblies for support of said pallet from a soft ground surface, said pallet including at least one pair of opposite side sets of journaled transverse rollers with each set of rollers including a pair of transverse rollers spaced apart longitudinally of said pallet and defining an upwardly opening cradle recess for cradling the lower peripheral portions of an associated drive wheel therein with said drive wheel supported from and disposed in driving engagement with said rollers, means drivingly connecting at least one roller of each set of rollers to the corresponding crawler track assembly, said crawler track assemblies each having an independently operable brake assembly operatively associated therewith, said pallet including upper surface portions adapted to support a wheeled vehicle therefrom including a pair of opposite side drive wheel assemblies driven from a differential assembly and with said drive wheel assemblies cradled by said sets of rollers and, said brake assemblies including hydraulic cylinder actuators each operatively connected to the corresponding brake assembly by means of a flexible hydraulic hose for portability of said actuators and to enable the latter to be supported in the operator''s cab of a wheeled vehicle supported on said pallet.
Claim 3
Dependent Claim
39 words

Claim 4
Dependent Claim
53 words
The combination of claim 1 wherein each of said pallet includes two longitudinally spaced sets of rollers drivingly connected to the corresponding crawler track assembly, the two sets of rollers on each side of said pallet being adapted to supportingly cradle the corresponding wheels of a tandem drive axle assembly equipped wheeled vehicle.
Claim 5
Dependent Claim
52 words
The combination of claim 1 wherein the opposite ends of said pallet include ramp means operatively associated therewith for driving a wheeled vehicle up onto one end of the pallet, along the latter and off the other end thereof, said ramp means being pivotally supported from oppOsite end portions of said pallet.
Claim 6
Dependent Claim
