25
Crawler crane
crane that looks like a tank
26
Truck-mounted crane
mobile because its a truck
27
Truck-mounted hydraulic crane
mobile crane with hydraulics
28
Gantry-mounted crane
mounted on top of a building and can move on rails
29
Tower-mounted crane
erected for beginning of job and left until job is complete.
30
Hammerhead crane
right angle crane mounted to the ground
31
Rough-terrain crane
Mobile hydraulic cranes with oversized tires
32
Carrydeck crane
vehicles for not so rough terrain
33
Estimate size and weight of load
Measure with tape or compare to other object, for weight, compare with other object or calculate cu ft.
34
Find load center of gravity
use a model, or usually in the center of load
35
Rigging safety
Proper PPE, know hand signals, trained, prepare
36
Planning a rigging job
Equipment capacity, equipment selection, equipment inspection, equipment setup, prelift checks,
37
How to select proper equipment for rigging
capacity of equipment never exceeded, nothing used for something it's not intended to be used on
38
Parts of simple block and tackle
Support hook, Frame, Rope, Sheave, Load Line, Hauling Line, Load Hook
39
Use of a simple block and tackle
Lift made by pulling down on the haul line to raise the load line.
40
Efficiancy factor
efficiency factor equals weight of load divided by rigger's lifting capacity, sheave equally distributes load
41
Parts of compound block and tackle
Support Hook, Fixed Block, Sheaves, Becket, Moveable block, load hook
42
Pre-use inspections of compound block and tackle
Weight of load, riggers lift capacity, mechanical advantage, where load moved, safety equipment, breaking strength of rope
43
Reeving a block and tackle
sections of rope are threaded so that each part of the rope supports a portion of the load weight
44
chain hoist
Uses set of gears to provide mechanical advantage to lift a load
45
Come Along
uses a handle and rachet mechanism to move a load chain through a body to lift a load
46
Ratchet Jack
Beam, hand lever, toe, load cap, lifts load from below using force from using handle
47
Screw Jack
Screw turns to raise load
48
Cribbing a jack
Strong timbers that are stacked in a criss-cross pattern under the load to rearrange the jack
49
Blocking a jack
Stout boards placed to prevent jacks from sinking under the weight of the load
50
Hydraulic Jack
Jack that raises or lowers using hydraulics
51
Winch
device designed to lift and move a load using a wire rope or chain
52
Effect sling angles have on capacity
the greater the angle, the lower the sling capacity gets
53
Hitch pattern effects on sling capacity
too lazy to describe, wider angle or less sling participation equals less capacity
54
Turnbuckle with sling length
can shift the loads center of gravity
55
Load leveler balancing a load
gear that you can turn to move the chain sheave
56
Shackle and inspection
horseshoe shaped with a pin that threads into the other end, check for wear, pin for straightness, no bends, threads
57
Hooks and inspection
I know what a hook is, hook body bends or cracks, tight nut, spreaded throat, safety latch works
58
Swivels and inspection
eye and/or hook and/or jaw, wear, cracks, or deformation, swivels turn, eye damage, bolt damage, or pin damage
59
Turnbuckle and inspection
Used to make small adjustments to length, wear, cracks, or deformation, threaded rods for damage or bends, stripping
60
Rigging links and equalizer plates and inspection
Block with a lot of holes to center load for lift, wear and cracks
61
Lifting lugs and eyebolts and inspection
already connected to load, eyebolts screw into load, wear or cracks, bends and damaged threads
62
Spreader beams and lifting beams and inspection
used on large bulky loads where slings can't be used. Cracks, wear, bent, or twisted
63
Tag Lines and inspection
rope handled by person to prevent spinning or swaying and guide load. wear and damage.
64
Common types of bridge cranes
Cab-operated overhead, floor operated overhead, Gantry crane, Cantilever Gantry crane, semi-gantry crane
65
Basic features of overhead cranes
bridge and trolley, controls
66
Different types of boom cranes
Rough terrain crane, truck mounted hydraulic crane, truck-mounted crane, crawler crane, locomotive crane,
67
Basic features of boom cranes
way of movement, crane parts, controller
68
Basic inspection checks for overhead cranes and crawler cranes
Check cranes major components for wear, damage, and improper reeving
69
How to read and interpret lifting capacity charts
Chart heading, lifting capacities, operating conditions, operating radius, boom point elevation, machine equipment, hoist reeving, loadline and whipline, maximum boom and jib lengths, jib lifting capacity
70
load-balancing techniques with heavy lifting
spreader beams and lifting beams, sling location, lugs or eyebolts
71
lifting personnel in basket with crane procedure
slow, can support 10 times the load, all brakes enabled when working, telescoping booms can show operator the extended length or accurate determination
72
load limits and number of people allowed in basket
capable of supporting 5 times weight of load, no more than 4 people
73
Crane personnel basket permit
must be approved, must be stated why they need to use the basket on the permit, can't be used for convienience, only used to reduce accident potential
