A triangular lift frame may include a first load block, a second load block and a third lift block, each load block including a hoist ring at each end. A first frame member extends between the first and second load blocks; a second frame member extends between the second and third load blocks; and a third frame member extends between the first and third load blocks. The frame members are arranged in a triangular fashion. In one embodiment, the triangular fashion may be such that a load force carried by each respective pair of load blocks is transmitted linearly longitudinally along a respective frame member extending between the respective pair of load blocks.
