PrefaceThis is the first edition of CSA B354.9, Design, calculations, safety requirements, and test methods for mast climbing work platforms (MCWPs). With respect to design and manufacturing criteria, this Standard is closely harmonized with the equivalent ISO 16369, Elevating work platforms - Mast-climbing work platforms.Scope1.1 General This Standard applies to mast-climbing work platforms (MCWPs) that are primarily used to provide a working surface for personnel, along with their necessary tools and materials, at elevated work locations. This Standard is applicable to MCWPs that include the following features (see Figures 1 and 2): a) one or more work platforms; b) one or more masts that arei) free-standing or laterally supported above their bases; ii) of fixed or variable height; iii) vertical or inclined between 0 and 30? to the vertical; and iv) vertically supported only at their bottom or top;c) movable or static base (chassis or base frame) capable of transfer at a work site by self-propulsion or towing or any lifting device; and d) an elevating mechanism that is manually or power operated. Raising and lowering speeds are limited to a maximum of 0.20 m/s (0.8 ft/s). 1.2 Purpose The purpose of this Standard is to specify minimum design, manufacturing, remanufacturing, rebuilding/ reconditioning, testing, and performance requirements for MCWPs to achieve the following objectives: a) prevention of personal injuries and accidents; b) uniformity in ratings; and c) understanding by manufacturers, dealers, installers, maintenance personnel, operators, owners, and users of their respective responsibilities. Note: MCWPs are generally intended for use over level surfaces. Normally, they are not insulated for use near electrically energized circuits, nor are they intended to be used in hazardous locations. For aerial platforms intended for use near electrically energized circuits, see CAN/CSA-C225. The operation of MCWPs is subject to certain hazards and therefore needs to be performed by a competent person trained in the intended use, safe operation, maintenance, and servicing of MCWPs. 1.3 Application This Standard applies to MCWPs manufactured after the date of publication of this Standard. 1.4 Equipment not covered This Standard does not apply to a) vehicle-mounted aerial devices covered by CAN/CSA-C225; b) non-self-propelled elevating rolling work platforms covered by CAN/CSA-B354.1; c) self-propelled elevating work platforms covered by CAN/CSA-B354.2; d) self-propelled boom-supported elevating work platforms covered by CAN/CSA-B354.4; e) construction hoists used to raise and lower materials and personnel covered by CAN/CSA-Z185 and CAN/CSA-Z256; f) mobile cranes covered by CSA Z150; g) vehicle-mounted vertical lift devices covered by ANSI/SAIA A92.7; h) vehicle-mounted bridge inspection and maintenance devices covered by ANSI/SAIA A92.8; i) permanently installed (non-mobile) elevating lifts used to transport personnel between different elevations; and j) firefighting equipment. 1.5 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. 1.6 Measurement 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.
