ABSTRACT:
A specially constructed pallet jack is used for transporting a heavy roll of paper having a central hollow core. The pallet jack includes a frame with elongated arms having first and second ends, with a first set of wheels mounted at the second end of the arms, and a second set of wheels mounted near the first end of the arms. A jack is provided for jacking up the first ends of the arms so that they are spaced from the wheels. Between the arms is a cradle having first and second ends with three obtuse angle-connected planar surfaces extending between the first and second ends. The first end of the cradle is pivotally mounted to the first ends of the arms, and the cradle is biased to a roll-receiving position by a gas spring. When a roll is rolled into the cradle, it pivots, dampened by shock absorbers to a roll-capture position in which the roll cannot spontaneously roll out of the cradle. A strap passes from the cradle through the core of the roll to positively hold it in place.
