ASME HST-5-2020 Performance Standard for Air Chain Hoists
standard by ASME International, 06/26/2020
Full Description
ASME has been defining hoist performance since 1983.ASME HST-5-2020 is a newly-revised Standard which establishes performance requirements for air powered chain hoists for vertical lifting service involving material handling of freely suspended (unguided) loads. These hoists use load chain of the roller or welded link types with one of the following types of suspension:
(1) lug;
(2) hook or clevis;
(3) trolley.
HST-5 contains an appendix which replaces the requirements of MIL-H-24591, Hoists, Chain, Pneumatic, Low Headroom, Trolley Type and, in conjunction with ASME HST-6-1999, Performance Standard For Air Wire Rope Hoists, replaces the requirements of MIL-H-28538B for Hoists, WireRope or Chain, Air Motor Powered With Trolley and MIL-H-2813 for Hoists, Chain and Wire Rope, Pneumatic.
This Standard is not applicable to: (1) damaged of malfunctioning hoists; (2) hoists that have been misused and abused; (3) hoists that have been altered without authorization of the manufacturer or a qualified person; (4) hoists used for lifting of supporting people; (5) hoists used for the purpose of drawing both the load and hoist up or down the hoist's own load chain(s); or (6) hoists used for marine and other applications as required by the Department of Defense (DOD).
HST-2 includes an appendix on Hand Chain Manually Operated Chain Hoists used in marine and other applications as required by the Department of Defense (DOD).
Both HST-5 and ASME HST-2-2018, Performance Standard for Hand Chain Manually Operated Chain Hoists serve as companion standards to ASME B30.16-2017, Overhead Hoists (Underhung).
Intended for manufacturers, owners, inspectors, chief and principal engineers, users and others concerned with performance requirements for hand chain manually operated chain hoists plus all potential governing entities.

Scope, Definitions, References, and Appendices
SECTION 5-0.1: SCOPE
This Standard establishes performance requirements for air-powered chain hoists for vertical lifting service in- volving material handling of freely suspended (unguided) loads using load chain of the roller or welded link types with one of the following types of suspension:
lug
hook or clevis
trolley
This Standard is applicable to hoists manufactured after the date on which this Standard is issued. It is not ap- plicable to
damaged or malfunctioning hoists
hoists that have been misused or abused
hoists that have been altered without authorization of the manufacturer or a qualified person
hoists used for lifting or supporting people, or
hoists used for the purpose of drawing both the load and the hoist up or down the hoist’s own load chain(s) The requirements of this Standard shall be applied together with the requirements of ASME B30.16. Please also refer to ASME B30.16 for requirements pertaining to marking, construction, and installation; inspection, testing, and mainte-
nance; and operation.
SECTION 5-0.2: DEFINITIONS
abnormal operating conditions: environmental conditions that are unfavorable, harmful, or detrimental to the operation of a hoist, such as excessively high or low temperatures, exposure to weather, corrosive fumes, dust-laden or moisture- laden atmospheres, and hazardous locations.
ambient temperature: the temperature of the atmosphere surrounding the hoist.
beam: an overhead standard structural or specially fabricated shape on which the trolley operates.
brake: a device, other than a motor, used for retarding or stopping motion by means of friction or power.
brake, holding: a friction brake for a hoist that is automatically applied and prevents motion when the air supply is interrupted.
brake, mechanical load: an automatic type of friction brake used for controlling loads in a lowering direction. This unidirectional device requires torque from the motor to lower a load but does not impose additional load on the motor when lifting a load. This may also be used as a holding brake if designed as such by the manufacturer.
braking, control: a method of controlling speed by removing energy from the moving body or by imparting energy in the opposite direction.
braking, dynamic: a method of controlling speed by using the motor as a compressor. chain, hand: the chain provided to control movement of a hand chain-operated trolley. chain, load: the load-bearing chain in the hoist.
chain, roller: a series of alternately assembled roller links and pin links in which pins articulate inside the bushings and the rollers are free to turn on the bushings. Pins and bushings are press-fit in their respective link plates.
chain, welded link: a chain consisting of a series of interwoven links formed and welded.
NOTE: Load chain properties do not conform to those shown in ASME B30.9.
control: a device or group of devices that serves to govern in some predetermined manner the power delivered to the apparatus to which it is connected.
