A lifting apparatus and method. The lifting apparatus comprising a lower bar assembly, an upper frame assembly, and a plurality of straps. The lower bar assembly comprises a first bar and a second bar. The upper frame assembly comprises a first upper frame bar, a second upper frame bar substantially parallel to the first upper frame bar, and a cross piece connecting the first upper frame bar to the second upper frame bar and substantially perpendicular to the first upper frame bar and the second upper frame bar. The plurality of straps are fixedly attached to the lower bar assembly and slidably attached to the upper frame assembly.

A hoist or hoisting device is configure to place a pallet on a roof without the need of a person on the roof. The hoist includes a deflector that moves between a first position and a second position and releases a strap from an open hook as the deflector moves from the first position. A release arm on the deflector contacts a portion of the strap to push the strap off the open hook after the pallet has contacted the roof. The hoist may then be raised and the strap be unthreaded and pulled upward through the pallet to leave the pallet installed on the roof.

A hoist cage assembly for lifting a pallet with a crane includes a cage that has a bottom end that is open for positioning around a pallet of material. The cage has a plurality of bar openings each extending through the cage. A plurality of bars is each of the bars is slidable through a respective pair of the bar openings to extend through the pallet when the cage is lowered over the pallet. Each of the bars rests on the cage when the cage is lifted to lift the pallet when the cage is lifted. A plurality of sleeves is each of the sleeves is coupled to the cage and the sleeves are strategically arranged on the cage thereby facilitating each of the bars to be slidably stored in the plurality of sleeves.

A socket assembly includes a socket. The socket defines a first interior space. The socket includes a first frame and a second frame disposed opposite to the first frame. The first frame is coupled with the second frame using at least one fastening member. The socket assembly includes a locking member disposed within the first interior space of the socket. The locking member includes a first portion and a second portion. The first and second portions define a second interior space for holding a rope.

A lifting apparatus may include a bolt assembly and a nut assembly. The bolt assembly may include a support plate, a bolt and a lifting eye attached to the support plate. The nut assembly may include a support plate, a nut and a handle attached to at least one of the support plate and the nut. A tether may also be included to connect the bolt assembly to the nut assembly.

A lifting device is provided, the lifting device providing a cable and a powered winch which winds and unwinds the cable. Each end of the cable provides a slack-adjustable point of attachment to a load. The points of attachment may each be attached to an opposing end of a load, such that each point of attachment provides a counterweight to the other point of attachment. Slack between the points of attachment may be tensed by a bridging connector. The lifting device may lift a load by two lateral points of attachment such that the load may be elevated off a floor with minimal vertical clearance, and may be laterally actuated by casters hanging on a suspended rail.
