shall: mandatory. should: advisory.
single wrap (layer) drum hoist: a type of winding drum hoist that accumulates the suspension wire rope in a single layer on the surface of the hoisting drum.
speed reducer: a positive-type speed-reducing machine. stability factor: the ratio of the stabilizing moment to the overturning moment.
strain rel ief anchor: a positive device used for the mechanical anchorage of cable to prevent undue strain on the cable connectors.
supported equipment: any building maintenance equipment that is held or moved to its working position by means of attachment directly to the building or extensions of the building being maintained.
suspended equipment (suspended scafftld): any building maintenance equipment that is suspended or moved to its working position by means of ropes or combination cables attached to some anchorage above the equipment.
tail line: the nonsupporting end of a suspension wire rope.
tie-in-device: the portion of a suspended unit that positively engages the building tie-in-guides.
tie-in-guides: the portion of a building that provides continuous positive engagement between the building and a suspended unit during its vertical travel of the face of the building.
fraction or sheave hoist: a type of hoisting machine that does not accumulate the suspension wire rope, but is designed to raise and lower a suspended load by the application of friction forces between the suspension wire rope and the hoist’s drum.
transfer drum: a drum incorporated within a hoist to transfer wire rope from one traction drum groove to an adjacent groove.
transportable equipment: ground-rigged powered platforms or supported equipment brought to a building site for the purpose of maintenance, as covered by this Standard.
transportable outriggers and davits: outriggers and davits designed to be moved from one work location to another.
traveling ladders and gaii fries (TLG): site-specific permanently installed traveling ladders or gantries used to service surfaces of a building such as an atrium roof, skylight, or building facade.
traveling cable: a cable intended to contain electrical power, control, or communication conductors from the power or communication source to a suspended or supported unit or between the source and a carriage.
frolleyline/dogline: a horizontal lifeline secured to the guardrail and structural portions of a platform (see para. 3.7.5.10).
(b) a platform suspended by two load-carrying wire ropes and with two secondary wire ropes such that the failure of any one support rope or its fastenings will not cause the platform to upset (substantially alter the normal position). Also known as two rope, two line, and dial-rope’. See foit r-rope s uspe’nde’d platform.)
we’afherproofi equipment or component protection constructed so that exposure to adverse weather conditions will not affect or interfere with the proper use or functions of the equipment or component.
winding drum hoist: a type of hoisting machine that accumulates the suspension wire rope on the drum of the hoist.
working platform: a suspended or supported platform arranged to provide access to the building.
wrap: one complete turn of the suspension wire rope around the surface of a hoist drum.
2 BUILDING DESIGN REQUIREMENTS
2.1 General
All buildings with wall surfaces requiring cleaning or buildings not provided with operable windows shall be designed relative to the use of the equipment covered by this Standard.
All buildings shall be designed to safely accommodate powered platforms and traveling ladders and gantries to be used for remedial work.
The design shall incorporate all features needed to provide the degree of safety required for users of the equipment and those exposed to use of the equipment.
All equipment and anchorages designed in accordance with this Standard shall be used only as herein described. Variations in use or modifications of its designed anchorages shall be approved, prior to use, by a registered professional engineer experienced in the design and installation of such equipment.
All loads and structural attachments to the building shall be approved by a registered architect or a registered professional engineer.
2.1.1 Installation Owner. When the equipment is to be continuously used at a specific location, the registered professional engineer for the building shall provide to the owner of each installation the following materials constituting the installation design record:
(a) architectural and structural drawings of those portions of the building contacted by the equipment or supporting the equipment.
