Claim Text:
1. A lifting apparatus, comprising: a base having a proximal end and a distal end; a receiving portion; a first pair of laterally offset arms rotatably coupled to the base for movement between lowered and raised positions, the first pair of arms being rotatably coupled to the receiving portion, the receiving portion being relatively near the base distal end when the first pair of arms is at the lowered position, the arms of the first pair of arms not sharing a common axis of rotation with one another; a second pair of laterally offset arms rotatably coupled to the base for movement between lowered and raised positions, the second pair of arms being rotatably coupled to the receiving portion, the receiving portion being relatively near the base distal end when the second pair of arms is at the lowered position, the arms of the second pair of arms not sharing a common axis of rotation with one another; wherein the base has a first wall extending from the proximal end to the distal end and being generally parallel to the first pair of arms; the first arm of the first pair of arms being on one side of the first wall and the second arm of the first pair of arms being on an opposite side of the first wall, such that from a top view the first wall is intermediate the first and second arms of the first pair of arms; and wherein the base has a second wall extending from the proximal end to the distal end and being generally parallel to the second pair of arms; the first arm of the second pair of arms being on one side of the second wall and the second arm of the second pair of arms being on an opposite side of the second wall, such that from the top view the second wall is intermediate the first and second arms of the second pair of arms.
