Suspension platform system

摘要

A suspension platform system having a work platform suspended from at least one modular mast by a hoisting system. The modular mast is composed of at least two mast units stacked vertically and attached to one another. Each mast unit has a multifunction rail including a plurality of safety engagement devices and a stabilizer guide device. The work platform has at least one mast stabilizer that cooperate with the stabilizer guide device to prevent undesired swaying of the suspended work platform. The hoisting system includes a carriages, hoist, and mast cable. The carriage engages the associated mast so that the carriage may be conveniently slid up and down the mast.

(a) a dextral mast unit perimeter (201) defining at least one closed two-dimensional dextral mast cross-section, including at least one dextral recessed perimeter portion (202), wherein the at least one dextral recessed perimeter portion (202) is at least partially bounded by at least two dextral guide-lock extensions (204) and the at least two dextral guide-lock extensions (204) are separated by a dextral locking neck width (205);(b) a dextral mast width (203), a dextral distal end (212), and a dextral proximal end (214); and(c) a dextral multifunction rail (216) partially defined by the at least one dextral recessed perimeter portion (202) and extending a majority of the distance from the dextral distal end (212) to the dextral proximal end (214), the dextral multifunction rail (216) including a dextral multifunction rail width (216a), a plurality of dextral safety engagement devices (217), and a dextral stabilizer guide device (222); (iii) a work platform (300) having a work platform sinistral end (302) and a work platform dextral end (304) and
(a) a sinistral mast stabilizer (320) attached to the work platform (300) and configured to cooperate with the sinistral mast stabilizer guide device (122) of the sinistral mast multifunction rail (116) to prevent undesired swaying of the suspended work platform (300) wherein a portion of the sinistral mast stabilizer (320) is smaller than the sinistral locking neck width (105) and a portion of the sinistral mast stabilizer (320) within the sinistral recessed perimeter portion (102) is larger than the sinistral locking neck width (105),(b) a dextral mast stabilizer (330) attached to the work platform (300) and configured to cooperate with the dextral mast stabilizer guide device (222) of the dextral mast multifunction rail (216) to prevent undesired swaying of the suspended work platform (300) wherein a portion of the dextral mast stabilizer (330) is smaller than the dextral locking neck width (205) and a portion of the dextral mast stabilizer (330) within the dextral recessed perimeter portion (202) is larger than the dextral locking neck width (205),(c) wherein the work platform (300) is located between the sinistral modular mast (100) and the dextral modular mast (200) such that the work platform sinistral end (302) is adjacent to the sinistral modular mast (100) and the work platform dextral end (304) is adjacent to the dextral modular mast (200); (iv) a hoisting system (400) configured to suspend the work platform (300) from the sinistral modular mast (100) and the dextral modular mast (200), including:
(a) a sinistral carriage (450) adapted for cooperative engagement with the sinistral mast multifunction rail (116) so that the sinistral carriage (450) may be conveniently slid up and down the sinistral modular mast (100) by a user, having a sinistral carriage proximal end (466), a sinistral carriage distal end (467), a sinistral carriage body (452), a sinistral cable connector (454), and a sinistral carriage mast engager (460) to releasably lock the sinistral carriage (450) to the sinistral mast multifunction rail (116) thereby preventing unintentional descent of the sinistral carriage (450);(b) a dextral carriage (470) adapted for cooperative engagement with the dextral mast multifunction rail (216) so that the dextral carriage (470) may be conveniently slid up and down the dextral modular mast (200) by a user, having a dextral carriage proximal end (486), a dextral carriage distal end (487), a dextral carriage body (472), a dextral cable connector (474), and a dextral carriage mast engager (480) to releasably lock the dextral carriage (470) to the dextral multifunction rail (216) thereby preventing unintentional descent of the dextral carriage (470);(c) a sinistral mast hoist (430) attached to the work platform (300) near the work platform sinistral end (302);(d) a dextral mast hoist (440) attached to the work platform (300) near the work platform dextral end (304);(e) a sinistral mast cable (410) attached to the sinistral cable connector (454) and the sinistral mast hoist (430) thereby suspending a portion of the work platform (300) from the sinistral carriage (450); and(f) a dextral mast cable (420) attached to the dextral cable connector (474) and the dextral mast hoist (440) thereby suspending a portion of the work platform (300) from the dextral carriage (470); and (v) at least one control system (500) in communication with the sinistral mast hoist (430) and the dextral mast hoist (440), wherein the at least one control system (500) operates the sinistral mast hoist (430) and the dextral mast hoist (440) to control the elevation of the work platform (300).
