While you should check out the latest set of regulations for yourself to get the full details, here are the main highlights:ġ) A multi-tiered load is defined as two or three individually rigged structural steel pieces that are aligned vertically, remain horizontal during lifting, and are all simultaneously lifted by a single crane. To address this hazard, Section 103 of the Construction Regulations have been greatly expanded and now give very detailed requirements. The process can greatly improve the speed of erection, but can also be hazardous if not carried out properly. Once the hook is empty, the operator lowers it to the rigging crew on the ground to load up the next set of members while the connectors finish bolting up the steel. The connectors then place each item in place starting with the bottom member and working up to the top. Basically, this is rigging up a number of structural items into a single multi-tiered load and lifting the entire group of them up to the connectors standing on the structure. If you’re in the steel erection business, you probably know the term “Christmas Treeing” as related to lifting a load of beams. The changes came into effect in September of 2006 so everyone should be following them now. The new rules are more stringent than past practice and require that special procedures be developed to ensure worker’s safety. These changes relate to multi-tiered loads for cranes and to operating equipment near power lines. However, along with these high profile changes to the Construction Regulations, other changes affecting the crane industry were also brought in with significantly less fanfare. At the same time as that legislation was brought in, the construction regulations for electrical safety were virtually completely restructured as well. Most people in the construction world heard about the new laws that came out for confined spaces a little while ago.
