hoist: amachineryunitthatis used forliftingorloweringa freely suspended (unguided) load. hoist, stationary: a base ordeck-, ceiling-, orwall-mounted hoist used for vertical lifting and lowering of freely suspended, unguided loads (see Figure 16-0.1-6). hoist, underhung: trolley hoists or hoists suspended from trolleys traveling on the lower flanges ofbeams or similar hoists that are hook- or lug-suspended. hoist operator, dedicated: an employee whose job is normally confined solely to the operation of the equip- ment. lifting devices: devices that are not normally reeved onto the hoistrope orchain, such as hook-on buckets, magnets, grabs, and other supplemental devices used for ease of handling certain types of loads. The weight of these devices is to be considered part of the load to be lifted. limitdevice:adevicethatlimitsequipmentmotionortakes control of particular functions without action of the operator when a limiting condition is reached. load, rated (capacity): the maximum load designated by themanufacturerforwhichtheequipmentisdesignedand built. load, working: the external load applied to the equipment, includingthe weightofload-attaching equipment, such as shackles and slings. load suspension parts: the load suspension parts of the hoistare the means ofsuspension (hookorlug), the struc- ture or housing that supports the drum or load sprocket, the drum or load sprocket, the rope or load chain, the sheaves or sprockets, and the load block or hook. lockout/tagout:the placementofalock/tagonthe energy- isolating device in accordance with an established proce- dure.
power transmission parts: the machinery components including the gears, shafts, clutches, couplings, bearings, motors, and brakes. qualified person: a person who, by possession of a recog- nized degree in an applicable field or certificate ofprofes- sional standing, or by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work. ratchet: a toothed member for engagementwith the pawl. reeving: a system in which a rope or chain travels around drums, sheaves, or sprockets. rope: refers to wire rope or synthetic rope per ASME B30.30. service, heavy: service that involves operation within the rated load limit that exceeds normal service. service, normal: service that involves operation with randomly distributed loads within the rated load limit, or uniform loads less than 65% of rated load for not more than 15% of the time for manually operated hoists and 25% of the time for electric- or air-powered hoists. service, severe: service that involves normal or heavy service with abnormal operating conditions. shall: a word indicating a requirement. sheave: a wheel or pulley used with a rope or chain to changedirectionandpointofapplicationofapullingforce. sheave, equalizer: a sheave used to equalize tension in opposite parts of the rope or chain. Because of its slight movement, it is not termed a running sheave. sheave, running: a sheave that rotates as the load block is lifted or lowered. should: a word indicating a recommendation. side pull: the component of the hoist pull acting horizon- tally when the hoist lines are not operated vertically. sprocket, idler: a freely rotating device that changes the direction of the load chain. sprocket, load: ahoistcomponentthattransmits motion to the load chain. This component is sometimes called load wheel, load sheave, pocket wheel, or chain wheel. stripper: a device that aids the load chain in leaving the load sprocket.
