Overhead travelling cranes are used to lift and move materials and establishing safety requirements for their operation and maintenance helps to protect workers from potentially hazardous and unsafe conditions. B167 covers design, inspection, testing, maintenance, and safe operation of these devices. The third edition 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.
This is the third edition of CSA B167, Overhead travelling cranes - Design, inspection, testing, maintenance, and safe operation. This edition supersedes the second edition, entitled Safety Standard for Maintenance and Inspection of Overhead Cranes, Gantry Cranes, Monorails, Hoists, and Trolleys, published in 1996, and the first edition, entitled General Purpose Electric Overhead Travelling Cranes, published in 1964.
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.
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).
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.
