Overhead travelling cranes - Design, inspection, testing, maintenance, and safe operation

1.1 This Standard specifies minimum requirements for the design, inspection, testing, maintenance (modifications and repairs), and safe operation of overhead cranes, monorails, hoists, trolleys, jib cranes, gantry and wall cranes, and other equipment having similar characteristics.

1.2 The following are not covered in this Standard: (a) mobile cranes and tower cranes (they are covered in CAN/CSA-Z150 and CAN/CSA-Z248, respectively); (b) personnel hoisting and elevating devices (they are covered in ASME A17.1/CSA B44 and CAN/CSA-Z185); (c) supporting building structures (see provincial building codes and CAN/CSA-S16); and (d) below-the-hook lifting devices, e.g., slings and rigging hardware (they are covered in other ISO and ASME Standards).

1.3 In CSA Standards, "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; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" 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.
