When working under loads

•materials must be rigged to prevent unintentional displacement •hooks must have self-closing safety latches or equivalent •all loads must be rigged by a qualified rigger
20

Hoisting & Rigging
Multiple lift rigging procedure
only when:
– a multiple lift rigging assembly is used – specifically within manufacturer’s specifications & limitations – maximum of 5 members hoisted per lift – only beams & similar structural members are lifted – only trained employees involved

Hoisting & Rigging
Multiple lift rigging procedure
– Bundles of decking are NOT appropriate for multiple lift.
– Even though metal decking meets the definition of structural members

22

•Components of the multiple lift rigging assembly must be specifically designed and assembled with a maximum capacity for total assembly and for each individual attachment point. •Based on manufacturer’s specifications with a 5 to 1 safety factor on all components
23

Hoisting & Rigging
Multiple lift rigging procedure

Total load must not exceed •rated capacity as specified in the hoisting equipment load charts and •rigging capacity specified in the rigging-rating charts

Ready to start??
Not really. I’d like to go through this “navigation thing” one more time.

YES! Run it!

79

Hyperlink
• An item (word, icon, button, etc) that will take you to another location (page in the document, web page, other program, etc)

• Hyperlinks are identified by the fact that when your cursor passes over them, it changes from an arrow to a hand.
– Sometimes they’re even underlined
