(2) A rope must not be fastened to a drum by a knot tied in the rope. (1) A rope must be secured to its winding drum, unless the line is required to automatically disengage from the drum. 15.12 Replacing pinsĪ shackle-pin must not be replaced with a bolt or other makeshift fitting. (2) The pin in a screw-pin type shackle must be wired or otherwise secured against rotation when used in applications that may cause the pin to loosen. (1) A shackle-pin, heel-pin and similar device must be secured against dislodgement. (2) A hook used in an application where manipulation of a safety latch or other retaining means may cause a hazard to a worker or where there is no hazard to a worker if the load becomes dislodged is exempt from the requirements of subsection (1). (1) A hook must have a safety latch or other means that will retain slings, chains, or other similar parts, under slack conditions. If a wedge socket is used as a wire rope termination, the dead end of the rope must be secured to prevent release of the wedge or rope slippage at the socket. Natural fibre rope must not be used for hoisting with a powered hoist. (b) 5 for wire rope of nonrotating construction. (ii) 3 for pendant lines, 3.5 for boom hoist reeving and 3.5 for load lines, at all times except during erection, and (i) 2.5 for pendant lines, 3 for boom hoist reeving and 3.5 for load lines, during erection, and The minimum design factor based on breaking strength for wire rope on a mobile crane, unless otherwise specified by the crane or wire rope manufacturer, is (3) The design factor for any rigging assembly used to support workers must be at least 10. (2) The design factors specified by subsection (1) may be reduced for a dedicated rigging assembly designed and certified by a professional engineer for a specific lift, but the dedicated assembly must be re-rated according to the requirements of subsection (1) for continued use. Table 15-1: Minimum Design Factors for Rigging ItemĪs specified by manufacturer but not less than 5 (1) The design factors based on breaking strengths for rigging components must be at least equal to the values given in Table 15-1, except as otherwise specified in this Regulation. (2) The WLL of existing fittings not identified as specified in subsection (1) must be determined by a qualified person, marked on the fitting and such fittings must be removed from service by January 1, 2001. (1) Rigging fittings must be marked with the manufacturer's identification, product identifier and the working load limit or sufficient information to readily determine the WLL. (2) The load applied to any rigging or rigging assembly must not exceed the working load limit. Loads to be unhooked by a worker must be safely landed and supported before the rigging is detached. Rigging and slinging work must be done by or under the direct supervision of qualified workers familiar with the rigging to be used and with the code of signals authorized by the Board for controlling hoisting operations. "rigging" means fibre ropes, wire ropes, chains, slings, attachments, connecting fittings and associated components "proof test" means a test applied to a product to determine material or manufacturing defects "design factor" means the theoretical reserve capability of a product, usually determined by dividing the breaking strength by the working load limit Table 15-3: WLL reductions for slings at an angleġ5.41 Multiple piece lifts WIRE ROPE SLINGSġ5.45 Temperature restrictions ALLOY STEEL CHAIN SLINGSġ5.51 Temperature restriction SYNTHETIC WEB SLINGSġ5.54 Synthetic web sling rejection criteriaįigure 15-3: Examples of synthetic web sling rejection criteria METAL MESH SLINGSġ5.56 Rejection criteria BELOW-THE-HOOK LIFTING DEVICESġ5.60 Part of lifted load Rigging Definitions Table 15-2: Installation and use of wire rope clips Table 15-1: Minimum Design Factors for Riggingįigure 15-1: Standard hand signals for controlling crane operations- Crawler, locomotive and truck cranes Forestry Operations and Similar Activities Diving, Fishing and Other Marine Operations Ladders, Scaffolds and Temporary Work Platforms Personal Protective Clothing and Equipment Noise, Vibration, Radiation and Temperature Occupational Health and Safety Regulation
