Q

Estimate size and weight of load

A

Measure with tape or compare to other object, for weight, compare with other object or calculate cu ft.

34
Q

Find load center of gravity

A

use a model, or usually in the center of load

35
Q

Rigging safety

A

Proper PPE, know hand signals, trained, prepare

36
Q

Planning a rigging job

A

Equipment capacity, equipment selection, equipment inspection, equipment setup, prelift checks,

37
Q

How to select proper equipment for rigging

A

capacity of equipment never exceeded, nothing used for something it’s not intended to be used on

38
Q

Parts of simple block and tackle

A

Support hook, Frame, Rope, Sheave, Load Line, Hauling Line, Load Hook

39
Q

Use of a simple block and tackle

A

Lift made by pulling down on the haul line to raise the load line.

40
Q

Efficiancy factor

A

efficiency factor equals weight of load divided by rigger’s lifting capacity, sheave equally distributes load

41
Q

Parts of compound block and tackle

A

Support Hook, Fixed Block, Sheaves, Becket, Moveable block, load hook

42
Q

Pre-use inspections of compound block and tackle

A

Weight of load, riggers lift capacity, mechanical advantage, where load moved, safety equipment, breaking strength of rope

43
Q

Reeving a block and tackle

A

sections of rope are threaded so that each part of the rope supports a portion of the load weight

44
Q

chain hoist

A

Uses set of gears to provide mechanical advantage to lift a load

45
Q

Come Along

A

uses a handle and rachet mechanism to move a load chain through a body to lift a load

46
Q

Ratchet Jack

A

Beam, hand lever, toe, load cap, lifts load from below using force from using handle

47
Q

Screw Jack

A

Screw turns to raise load

48
Q

Cribbing a jack

A

Strong timbers that are stacked in a criss-cross pattern under the load to rearrange the jack

49
Q

Blocking a jack

A

Stout boards placed to prevent jacks from sinking under the weight of the load

50
Q

Hydraulic Jack

A

Jack that raises or lowers using hydraulics

51
Q

Winch

A

device designed to lift and move a load using a wire rope or chain

52
Q

Effect sling angles have on capacity

A

the greater the angle, the lower the sling capacity gets

53
Q

Hitch pattern effects on sling capacity

A

too lazy to describe, wider angle or less sling participation equals less capacity

54
Q

Turnbuckle with sling length

A

can shift the loads center of gravity
