What is multiple lift rigging?
Beside this, what is the minimum distance between structural steel members when hoisted on a multiple lift rigging assembly?
One may also ask, what is the tandem lifting? When lifting heavy or oddly shaped objects, it is sometimes desirable to use two cranes in tandem rather than a single higher-capacity crane. Tandem lifts can be very useful, and they are often used to place structural beams for bridges, move large loads, and lift long components from horizontal to vertical positions.
Likewise, people ask, what is the required safety factor for components of a multiple lift rigging assembly?
Multiple-lift rigging assembly capacity, for the total assembly and for each individual attachment point, must [29 CFR 1926.753(e)(2)]: Be certified by the manufacturer or a qualified rigger. Be based on the manufacturer's specifications. Have a 5-to-1 safety factor for all components.
What is the factor of safety specified for rigging equipment?
1 The factor of safety is the ratio between the minimum breaking load and the safe working load. 3.2. 2 The factor of safety for the following equipment must not be less than 6:1: (a) Web slings; (b) Round slings; (c) Shackles.
