four-rope suspended platform: a platform suspended by four load carrying wire ropes arranged 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 four rope, four line, and utulti-n,pe. See two-rope spended platform.)

guide shoe: equivalent to guide rollers, except shoes provide a sliding contact between the building guides and

the shoe.

hotsling machine: a device intended to raise and lower a suspended or supported unit.

installation: the total affected parts of a building and the equipment associated with the intended operation.

interlock: a device to ensure operations or motions in proper sequence.

live ad (static): the total static weight of personnel, tools, parts, and supplies that the equipment is

designed to support.

multiple wrap (layer) drum hoist: a type of hoisting machine that accumulates the suspension wire rope in more

than one successive layer on the surface of the drum of the hoist.

nondestructive tests: those tests required to ensure the reliability or soundness of a product but which do not

have a detrimental effect on the product.
