CSA B167-2016 Overhead cranes, gantry cranes, monorails, hoists, and jib cranes.
Structural steel bolts used on structural connections for the primary or main load shall be high tensile bolts such as ASTM A325 or A490 bolts or equivalent. For critical connections, the use of high strength body-bound bolts should be considered. Usage of structural bolts should be in accordance with industry standards for such fasteners. Bolts shall be appropriate to their purpose. Bolts shall not be reused. Bolts shall not be over-torqued.
The trolley frame should be of a steel welded construction and be designed to adequately transmit the load to the trolley wheels and the trolley rails.
5.3.5 Runway and supporting structure
It shall be confirmed and documented that the design and installation of runways for cranes and
monorails is in accordance with CSA 516 and CISC Guide for the Design of Crane Supporting Steel
5.3.6 Ladders, stairs, walkways, service platforms, and handrails
Ladders, stairs, service platforms, walkways, and handrails shall be designed in accordance with
CMAA Specification 70 or CMAA Specification 74 and applicable requirements.
1) Applicable requirements include provincial/territorial occupational health and safety regulations. In the event of conflict with this Standard, regulatory requirements take precedence.
2) Provincial/territorial regulations for fall arrest equipment (e.g., anchor points) can apply.
Overhead travelling cranes shall be designed to provide easy and safe access to the operator position and to frequently accessed service points, with appropriate handrails, guarding and self-closing gates or barriers. Maintenance platforms that are not used as walkways and are designed for mechanical and electrical equipment access should be as large as practicable, given space and machinery obstructions, to allow for easy, safe access.
5.4 Mechanical requirements
Gears should be designed and manufactured in accordance with recognized standards for such
Note: Recognized standards and guidelines include those published by the American Gear Manufacturers
Association (AGMA). Equivalent recognized standards may be used.
Bearings shall be selected to be consistent with the intended use of the crane or hoist, and with the classification of an overhead travelling crane. In general, anti-friction bearings should be used. Anti- friction bearings shall be selected on the basis of the BlO life of the bearing. Bushings should not be used.
