Abstract
Devices, systems, and methods are provided for helping hand trucks lift heavy objects. A device for attaching to hand trucks and lifting objects may include a pallet portion for lifting weight, the pallet portion having a bottom portion facing the ground and a top portion, wherein weight is arranged on the top portion; an angle maintaining portion attached to the bottom portion, wherein when the angle maintaining portion is touching the ground, the pallet portion is positioned at an angle greater than zero relative to the ground; and one or more slots attached to the bottom portion, wherein the one or more slots are configured to attach to a hand truck nose blade by sliding the hand truck nose blade into the one or more slots.
Claims16
A device for attaching to hand trucks and lifting objects, the device comprising:
- a pallet portion for lifting weight, the pallet portion comprising a bottom portion facing the ground and a top portion, wherein weight is arranged on the top portion;
- an angle maintaining portion attached to the bottom portion more proximate to the center of the bottom portion than to any ends of the bottom portion, wherein when the angle maintaining portion is touching the ground, the pallet portion is positioned at an angle greater than zero relative to the ground and not parallel to the ground;
- first members attached to and extending downward toward the ground from opposite respective sides of the bottom portion;
- and
- a second member extending between the first members, wherein the first members, the second member, and the bottom portion form one or more slots configured to receive a hand truck nose blade by sliding the hand truck nose blade into the one or more slots,
- wherein the angle maintaining portion extends further from the bottom portion than the first members extend from the bottom portion,
- wherein the angle maintaining portion extending further from the bottom portion than the first members extend from the bottom portion positions the pallet portion at a non-parallel angle with respect to the ground and at which the angle maintaining portion and the second member prevent the bottom portion from contacting the ground.
