A system and method for delivery of packaged goods on a pallet with a pallet jack is described. The pallet jack enables substantially easy navigation over rough terrain through the configuration and placement of the left and right rear wheels and the configuration and placement of the left and right front wheels, as well as the design and implementation of handle bars. Other useful features include a basket for holding personal items, and jacks for retaining hand held devices that can be used to track and update deliveries and orders for goods. Accordingly, the pallet jack is preferably used to deliver consumer soft drink beverages but can be used to deliver any type of packaged product, goods and/or raw materials.

What is claimed is: 1. A pallet jack, comprising:a left tine and a right tine, of substantially similar length, wherein the left and right tines are substantially planar and substantially parallel to each other;a lifting mechanism configured to lift the left and right tines;a pallet jack body attached to a rear-most portion of each of the left and right tines, the pallet jack body includinga substantially vertical backing portion attached to the rear-most portion of each of the left and right tines, anda substantially horizontal portion attached to a lowermost portion of the substantially vertical backing portion, andwherein the lifting mechanism is attached to the substantially horizontal portion of the pallet jack body along a centerline of the pallet jack;a vertical lifting handle coupled to the lifting mechanism, the vertical lifting handle having a loop-shaped handle disposed at a top thereof and extending in a plane substantially parallel to the substantially vertical backing portion, the vertical lifting handle being movable in a plane orthogonal to said plane parallel to the substantially vertical backing portion to actuate said lifting mechanism;two loop-shaped side handles respectively attached to upper left and right sides of said substantially vertical backing portion, each loop-shaped side handle extending in a plane substantially parallel to the plane in which the vertical lifting handle is movable, each loop-shaped side handle extending rearward of said substantially vertical backing portion in a direction toward said vertical lifting handle but not so far as to intersect the plane in which the vertical lifting loop-shaped handle extends;a substantially horizontal handle bar connector coupled to said two loop-shaped side handles at a position above a top of the vertical lifting loop-shaped handle;a left front wheel located and rotationally attached to a front-most portion of the left tine;a right front wheel located and rotationally attached to a front-most portion of the right tine;a left rear wheel located along a centerline of the left tine; anda right rear wheel located along a centerline of the right tine, wherein each of the left and right rear wheels is configured to independently rotate in a substantially vertical plane about its respective center, and further wherein each of the left and right rear wheels is configured to independently rotate in a substantially horizontal plane,wherein each of the left rear wheel and the right rear wheel is non-cylindrical and has an aspect ratio between about 5 and about 18, with a height of between about 5 inches to about 7 inches, and a width of between about 0.5 inch and 1.5 inches,wherein each of the left front wheel and the right front wheel is non-cylindrical and has an aspect ratio between about 4 and about 14, with a height of between about 7 inches to about 9 inches, and a width of between about 0.5 inch and 1.5 inches, andwherein the respective aspect ratios of the front wheels and rear wheels enable the pallet jack to have an improved ability to navigate both substantially non-smooth exterior surfaces and surfaces that include gravel, holes, cracks and differences in height.
