Abstract: A rack and a hoist system. The rack is L-shaped with a first planar floor/leg and a second planar floor/foot, which is a solid plate. The first floor has three pairs of wheels with the middle pair larger than the other pairs and a mount to couple to the hoist via a hooked line that couples to a double-hooked line that hooks into apertures through paired mounting plates near the top end of the leg. The foot includes a tag-line mount from which a tag-line may be mounted to help guide movement thereof using the hoist. The foot includes wheels such that when the first floor is tipped up while being lifted, the wheels of the foot engage with the surface while the wheels on the leg are disengaging. There are flanking posts, strap structures, and flanking plates that help to secure the load (e.g. rebars, pipes, and sheet rock).

Abstract: A hoisting platform system configured to permit transport of loads to and between floors of a building. The system includes a roof lift having a pair of beams resting on a roof and jutting out therefrom. The roof lift includes a winch coupled to and positioned over the beams. The roof lift includes a mounting structure extending upwardly from the beams with a plurality of cables coupled to and extending from a top region of the mounting structure downwardly at an angle. The cables are fixedly coupled to the roof. The hoisting platform system includes a floor deck disposed below the roof lift. The floor deck is coupled to a floor of the building and extending outwardly therefrom.
