Leverage lifting cart, utilizeable along two distinct and generally horizontal planes, has a longitudinal cargo receiving bed attached to a pair of laterally extending and preferably wheeled axles including a fixed-elevational rear-axle and a front-axle carried by a vertically controllably movable carriage extending pivotably and medially downwardly from the cargo bed. The vertical distance between the carriage supported front-axle and the cargo bed is remotely controllable by an operator nearby the cargo bed front-end. Specially contoured bridges connect the rear-axle to the front-axle. By virtue of this basic structure, and which can be desireably augmented with other novel structural features, the operator can leverage cargo loads between disparate planes and can safely, reliably, and conveniently maneuver the loaded cargo along the available expanse of one or more planes. The cargo bed is forwardly equippable with cargo anchoring and abutment parts so that the cargo itself can augment the structural strength of the leverage lifting cart.

Leverage lifting cart having a procurement mode traversible along a substantially horizontal substrate and at said procurement mode comprises: (A) a cargo bed extending lengthily longitudinally along a central-axis that is inclined forwardly and upwardly from a said substrate whereby said cargo bed has: a rear-end nearer to said substrate; a front-end overlying said substrate; and an inclined loadable upper-side having a lengthier forward region and also a shorter rearward region for receiving and discharging an arbitrarily selectable load; (B) said cargo bed at the rear-end being provided with a directionally laterally extending rear-axle; (C) said cargo bed nearer to the rear-end than to the front-end thereof being provided with a primary-pivot station, the majority of said upper-side rearward region being located rearwardly of said primary-pivot station; (D) said cargo bed forwardly of said primary-pivot station being provided with anchoring means that permits a cargo load to be attached to the cargo bed forward region; (E) said cargo bed between said primary-pivot station and said anchoring means being provided with a longitudinally movable and arrestable abutment means for abutting a forward portion of a said arbitrarily selectable load; (F) a carriage means establishing a cargo bed inclination of the procurement mode and permitting it to traverse along a said substrate, said carriage means comprising: (Fi) a controllably collapsible upright strut means including a strut upper-length that is pivotably attached to said primary-pivot station and that is pivotably attached to a strut lower-length having a directionally laterally extending front-axle, (Fii) said rear-axle and front-axle being respectively provided with substrate-engaging means, and (Fiii) located immediately above and extending along said substrate, laterally separated, non-linear and fixed-length bridge members respectively attached to said rear-axle and to said front-axle so that when said cargo bed is parallel to said substrate, said bridge members lie at an acute angle relative to said substrate; and (G) control means actuatably extending forwardly upwardly from said collapsible strut means and also alongside the cargo bed, said control means having a forward terminus manually controllably movable from an off-station to an on-station that permits strut means collapsibility, and said forward terminus being manually accessible to an operator located forwardly remote of said cargo bed primary-pivot station.
