PrefaceThis is the first edition of CSA B354.5, Mast-climbing work platforms.
The purpose of this Standard is to provide design, manufacturing, remanufacturing, rebuilding/reconditioning, testing, performance, inspection, training, maintenance, and safe operation criteria formast-climbing work platforms.
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.
An MCWP typically includes the following features (see Figures 1 and 2):
(a) one or more work platforms;
(b) one or more masts that are
(i) free-standing or laterally supported above their bases;
(ii) of fixed or variable height;
(iii) vertical or inclined between 0 and 30Â° to the vertical; and
(iv) vertically supported only at their bottom or top;
(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).
The purpose of this Standard is to specify minimum design, manufacturing, remanufacturing, rebuilding/reconditioning, testing, performance, inspection, training, maintenance, and safe operation 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.
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 competent, careful personnel trained in the intended use, safe operation, maintenance, and servicing of MCWPs.
The design and manufacturing requirements of this Standard apply 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 CAN/CSA-Z150;
(g) vehicle-mounted vertical lift devices covered by ANSI/SIA A92.7;
(h) vehicle-mounted bridge inspection and maintenance devices covered by ANSI/SIA A92.8;
(i) permanently installed (non-mobile) elevating lifts used to transport personnel between different elevations; and
(j) firefighting equipment.
In CSA Standards, â€œshallâ€ is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; â€œshouldâ€ is used to express a recommendation or that which is advised but not required; â€œmayâ€ is used to express an option or that which is permissible within the limits of the standard; and â€œcanâ€ is used to express possibility or capability. 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.
