Mich. Admin. Code R. 408.10575e - Intermittently stabilized platforms
Rule 575e.
(1)
The intermittently stabilized platform shall be in compliance with the
requirements of
R 408.10575b(1) to
(13).
(2) Each stabilizer tie shall be equipped
with a quick-connect and quick-disconnect device that cannot be accidentally
disengaged, that is for attachment to the building anchor, and that is
resistant to adverse environmental conditions.
(3) The platform shall be provided with a
stopping device that will interrupt the hoist power supply if the platform
contacts a stabilizer tie during its ascent.
(4) Building face rollers shall not be placed
at the anchor setting if exterior anchors are used on the building
face.
(5) Stabilizer ties that are
used on intermittently stabilized platforms shall allow for the specific
attachment length that is needed to effect the predetermined angulation of the
suspended wire rope. The specific attachment length shall be maintained at all
building anchor locations.
(6) The
intermittently stabilized platform shall be in continuous contact with the face
of the building during ascent and descent.
(7) The attachment and removal of stabilizer
ties shall not require the horizontal movement of the platform.
(8) The platform-mounted equipment and its
suspension wire ropes shall not be physically damaged by the loads from the
stabilizer tie or its building anchor. The platform, platform-mounted
equipment, and wire ropes shall be able to withstand a load that is not less
than twice the ultimate strength of the stabilizer tie.
