1.1 Inclusions
This standard specifies minimum requirements for the design, construction, installation, operation, inspection, testing, alteration, and maintenance of permanently installed manlifts for the vertical or inclined vertical transportation of authorized personnel and, where authorized, their tools and equipment. Such manlifts are typically installed in structures such as grain elevators, radio antennas, bridge towers, underground facilities, dams, power plants, pulp mills, and similar structures.
The types of manlifts included are:
Power-type manlifts
Rack-and-pinion manlifts
Traction machines
1.2 Exclusions
This standard does not apply to
mine hoists;
hoists for raising and lowering personnel or materials or both (such hoists are covered by CSA Standards CAN/CSA- Z185 and CAN/CSA- Z256);
devices covered by ASME A17.1/CSA Standard B44;
devices suspended access equipment covered by the CSA Standard CAN/CSA- Z271 Standardand the CSA B354 series of standards; and
devices and elevating work platforms covered by the CSA B354 series of Standards.
1.3 Terminology
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
1.4 Units of measure
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
