ASME A120.1:2014 pdf free download.Safety Requirements for Powered Platforms and Traveling Ladders and Gantries for Building Maintenance.
wire rope rngagmg: a brake that grips onto a wire rope, without damage to the rope, to prevent the descent of a suspended unit.
building: a structure wherein people may live, work, or otherwise make use of the facilities offered within the structure.
building face rolkr: a guide roller designed to ride on the face of the building wall to prevent the suspended or supported equipment from abrading the face of the building.
building r,uiintenaj,ce: exterior or interior operations such as window cleaning, caulking, metal polishing. reglazing, and general light maintenance or repairs on building surfaces.
cable: a conductor, or group of conductors, encked in a weatherproof sheath, which may be used to supply electrical power or control currents for equipment and to provide voice communication circuits.
carriage: a wheeled vehicle used normally for the horizontal movements and support of equipment. catalc strength: the rated strength of any product or material as designated by its manufacturer or vendor, based on standard testing procedures or acceptable engineering design practices.
certified: accepted by design, evaluation, or inspection by a registered professional engineer.
combination cable: ropes having both steel structural members for support of the equipment and copper or other electrical conductors insulated from each other and the structural members by nonconductive barriers.
continuous pressure: the requirement for a constant manual actuation of an operating control or device.
control: a mechanism used to regulate or guide the operation of the equipment.
core: the axial member of a wire rope about which the strands are laid.
da’it: a device for suspending a powered platform. Unlike outriggers, a davit reacts its operating moment load into a single pedestal, socket, carnage attachment, or other connection.
dropline: see lifeline.
diinamic load: loading induced by masses undergoing changes in velocity and loads varying with time. In application,a simulated static load surcharge may beassumed to be equivalent to dynamic effects.
electrical ground: a conducting connection between anelectrical circuit of the equipment and the earth, or aconducting body that serves in place of the earth.equsipment tie-in: a positive-type connection provided tosecure a working platform or suspension rope to thebuilding.
failure: a deficiency of a structural element that makesit unable to continue the load-bearing function for whichit was originally designed.
fairlead: the uppermost guide for the suspension wirerope.
fairlead roller: a roller provided to allow a minor changein the direction of travel of a suspension rope.
four-rope suspended platform: a platform suspended byfour load carrying wire ropes arranged such that thefailure of any one support rope or its fastenings willnot cause the platform to upset (substantially alter thenormal position). (Also known as four rope, four line,and multi-rope. See fvo-rope suspended platform.)
