Rigging 1

Rigging

QuestionAnswer
1. Rigging involves choosing the appropriate ___ to support the load weight, attaching them to the ___ equipment, and arranging them properly to ___ the load components, lifting, balance
2. What are the primary concerns when planing a lift determining the weight and balance of the load
3. Other than the primary concerns listed in the previous question, what are some other considerations that need to be taken into account when preparing for a lift load shape, path of travel, location, and landing areas
4. How can load weight be determined if the load does not consist of stock shapes and total weight information is not available calculate from load's area and/or volume based on measuring actual dimensions
5. How much does 300' of 1/2" conduit weigh
6. What is the weight of an aluminum billet (block) measuring 2' wide by 6" high by 10' long
7. What is the volume of copper rod 96" in length and 1" in diameter
8. What must be determined so that a load remains stable and level when lifted load's center of gravity
9. A load must be lifted from directly over the ___ in order to maintain balance center of gravity
10. A ___ load is a load in which one half of the load is a mirror image of the other half symmetrical load
11. A ___ load is a load in which one half of the load is substantially different from the other half asymmetrical
12. ___ loads always tilt toward the center of gravity unbalanced
13. Without performing center of gravity calculation, how can load balance be checked estimate the center of gravity then lift load slightly observe stability and shifting
14. The vertical location of the lift points in relation to the center of gravity also affects the stability of a load. True or False True
15. The relative distances of the lift points from the center of gravity determine their share of the ___ load
16. What is a lifting lug? Thick metal loop for lifting
17. An ___ is a bolt with looped head that is fastened to a load to provide a lift point eye bolt
18. ___ are pressed into their closed-loop shape in a process that keeps the steel strong forged loops
19. Only formed steel eyebolts should be used for lifting applications. True or False false
20. List three common types of eyebolts machinery, regular nut, & shoulder nut
21. The __ eyebolt is the most commonly used eybolt machinery
22. Nut eyebolts have a shoulder that butts up against a threaded nut. True or False
23. a regular-nut eyebolt and a shoulder-nut eyebolt(where the shoulder is not used) should never be used with rigging that pulls on eyebolts at an angle True or False True
24. The load capacity of an eyebolt is greatest when it is pulled ___ vertically
25. When are slings needed when there are no existing attachments points
26. List the sling types used in rigging and lifting applications vertical, bridle, basket, and choker
27. What is a sling hitch sling with a loop at both ends for lifting
28. Identify the 4 basic types of sling hitches from pictures p 4 vertical, basket, bridle, and choker
29. A __ hitch consists of two or more straight slings( of the same type) that bring together multiple lifting points on the load to a single hoisting point. bridle
30. A ___ hitch uses one sling that is looped under the load so that both ends can be connected to the hoist. basket
31. Basket sling loads are commonly used with loads such as pipes, bars, or poles that are drawn together in a bundle True or False False, Chokers do p 12
32. What is sling angle The angle between the horizontal and sling
33. Greater sling angles result in greater sling forces. True or False False. Smaller sling angles do
34. What is the formula used to calculate the actual force on a sling F = w * f
35. What would be the angular force factor in calculating a sling angle of 30 degrees
36. A 1,00 lb load is supported by a pair of slings at an angle of 30 degrees. Each sling supports half of the load (500lbs) at 30 degrees, and the angular fore factor is 2.000. WHAT is the actual force experienced by each sling
37. If angular forces cause a flexible load to buckle, a __ can be added to the rigging to change the direction of the forces on the load. spreader bar
