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.
