Abstract
A shoulder harness is made of straps forming a figure eight having a criss-cross strap configuration, in one embodiment, across a user's back. Two loops are formed which hang under the user's arms. The loops may be threaded into slots on the top of a wide tension buckle, which is centered in front of the user. A webbed lift strap about five-inches wide is threaded into the base of the tension buckle. A second user threads the opposite end of the lift strap into the base of the second user's tension buckle. The lift strap is placed under a load and carried by the two users over rough surfaces that dolly wheels could not handle. Another embodiment includes a central ring to join three or more users' straps together. Another embodiment is a shoulder harness made of vertically hanging straps.

A lifting harness comprising:
- a strap configured into a figure eight to form a left and a right support loop sized to fit around a first user's torso;
- a tension buckle having webbing slots housed thereon to receive the left and the right support loops;
- wherein said tension buckle comprises at least one side panel having a receiving slot to receive a central roller;
- said tension buckle further comprises a unitary one piece body segment having a left and a right webbing slot formed in said one piece body segment and a knurled, cylindrical central roller that slides up and down in roller slots on side panels of the unitary one piece body segment of the tension buckle;
- a central lift strap mounted to said tension buckle, thereby enabling the central lift strap to be connected to a second user's tension buckle to use the central lift strap to lift and carry objects;
- wherein the left support loop mounts through the left webbing slot located along a top edge of a central body piece of the tension buckle, and the right support loop mounts through the right webbing slot located along the top edge of the central body piece;
- wherein during a downward force exerted on the central lift strap, a front segment of each of the left and right support loops lies flat against the first user's torso;
- wherein the tension buckle of each of the first and the second user is supported in the front of each user respectively;
