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.
Claims20
A hoisting platform system configured to permit transport of loads to and between floors of a building, comprising:
- a) a roof lift coupled directly to a top surface of a roof of a building, the roof lift including a pair of beams resting on the roof and jutting out from a side of the roof, a winch coupled to and positioned over the beams, and a mounting structure extending upwardly from the beams with a plurality of cables fixedly coupled to and extending from a top region of the mounting structure downwardly at an angle, the cables being fixedly coupled to the roof;
- and
- b) a floor deck disposed below the roof lift, coupled to a floor of the building and extending outwardly therefrom, wherein the system does not include a plurality of horizontal rods at a top thereof to couple directly to an underside of a ceiling and does not include any post jacks.
A roof lift configured to be coupled directly to a top surface of a roof of a building, the roof lift comprising:
- a) a pair of beams resting on the roof and jutting out from a side of the roof,
- b) a winch coupled to and positioned over the beams, and
- c) a mounting structure extending upwardly from the beams with a plurality of cables fixedly coupled to and extending from a top region of the mounting structure but with no post jacks.
A hoisting platform system configured to permit transport of loads to and between floors of a building, comprising:
- a) a roof lift configured to couple directly to a top surface of a roof of a building, the roof including a pair of beams resting on the roof and jutting out from a side of the roof, a powered winch coupled to and positioned over jutting portions of the beams, a set of rigid struts extending upwardly from the beams and coupled to each other at a top region of the struts by a cross-beam, a plurality of tension-adjustable cables fixedly coupled to and extending from a top region of the struts, anchors coupled to distal ends of the cables and configure to anchor the cables to a top surface of a roof and a retractable deck disposed between the jutting portions of the beams;
- and
- b) a plurality of floor decks with retractable decks configured to be disposed below the roof lift in an array, configured to be coupled to various floors of a building and to extend outwardly therefrom.
