Scope

This Standard applies to the design, construction, installation, maintenance, inspection, and operation of conveyors and conveying systems in relation to hazards. The conveyors may be of the bulk material, package, or unit-handling types, where the installation is designed for permanent, temporary, or portable operation. This Standard shall apply, with the exceptions noted below, to all conveyor installations. This Standard specifically excludes any conveyor designed, installed, or used primarily for the movement of people. This Standard does, however, apply to certain conveying devices that incorporate within their supporting structure workstations or operator’s stations specifically designed for authorized operating personnel. This Standard does not apply to conveyors for which specific standards are already in effect, or to equipment such as industrial trucks, tractors, trailers, automatic guided vehicles, tiering machines (except pallet load tierers), cranes, hoists, power shovels, power scoops, bucket drag lines, trenchers, platform elevators designed to carry passengers or an operator, manlifts, moving walks, moving stairways (escalators), highway or railroad vehicles, cableways, tramways, dumbwaiters, material lifts, industrial scissors lifts, pneumatic conveyors, robots, or integral machine transfer devices. Some of the foregoing have specific standards. The provisions of this Standard shall apply to equipment installed 1 yr after the date of issuance. 本标准适用于输送机和输送系统与危险相关的设计、建造、安装、维护、检查和操作。输送机可以是散装材料、包装或单元处理类型，其中安装设计为永久、临时或便携式操作。除下述情况外，本标准适用于所有输送机安装。本标准明确排除了任何设计、安装或主要用于人员移动的输送机。但是，本标准适用于在其支撑结构工作站或专门为授权操作人员设计的操作员站内包含的某些输送设备。本标准不适用于特定标准已经生效的输送机，也不适用于工业卡车、拖拉机、拖车、自动导引车、分层机（托盘负载分层机除外）、起重机、起重机、动力铲、动力铲、铲斗拖线、挖沟机、设计用于载客或操作员的平台电梯、载人、自动人行道、移动楼梯（自动扶梯）、 公路或铁路车辆、索道、有轨电车、哑巴、物料升降机、工业剪刀式升降机、气动输送机、机器人或一体式机器传输装置。上述一些有特定的标准。本标准的规定适用于发布之日起1年后安装的设备。
