Part 6 Cranes, Hoists and Lifting Devices

Section 86 Hoist brakes

Clauses 21.8 and 21.9 of CSA Standard Z256-M87 (R2001), Safety Code for Material Hoists, describe detailed requirements for brakes. Most material hoists are fitted with an auxiliary braking mechanism sometimes referred to as a “broken rope device”. Activated in the event of a hoisting rope failure, brake cams clamp the frame of the hoist mast and stop the car from descending.
