ALP=17000 you can only lift what you are reeved for!
Block=260
Rigging=200
Hose Reel=190
JIB=330
manufacturers tag or stamp
rated capacity
a load picked below the center of gravity is what?
top heavy or unstable
in a basket hitch each leg carries the entire weight of the load
what is a 30 degree angle
cut down on friction, and possible pin and ear damage, increase the life of the shackle
what is the purpose of using a shackle in the bight of a choke? or placing the pin in the eye of the sling?
TSS GROSS CAPACITY FOR A BOOM LENGTH of 60ft and a loaded boom angle of 52 degrees.
what is 3110?
pin to pin bow to bow
what is a 4 shackle transfer
before attaching rigging we must
what is inspect
Horizontal sling angle of Metal mesh slings
what is 90 or be between 0 and 5 degrees from vertical?
60 degrees to 90 degrees
what is the ideal sling angle?
two arms two swipes
what is emergency stop
1 1/2 times
What is the depth of the eyebolt in a blind hole application?
The ratio between the breaking point of the rigging hardware and the Working load limit or capacity of that hitch type.
what is a design factor?
in a tandum lift the larger crane is over the center of gravity.
What is the crane that will hold the greatest amount of the load, and generally has the most vertical sling position?
1.414
Tension factor or sling factor for 45 degree horizontal sling angle
backing that crane up
What is when a spotter must be posted when backing a crane into a location. No matter if using mirrors or walking the route of travel. A signalman/spotter must be posted.?
1/3 the width of the eye
What is the maximum length an object can be when placed into a synthetic websling?
I do not have a shoulder.
What is the unshouldered eyebolt?
drag that sling out of there.
What is what you should not do in removing rigging from a load. The load should be on cribbing for easy removal.
60, 60, 60
What is the ideal sling angle of an equilateral sling setup, all sides are equal length and directly over the center of gravity?
I am rigging I can be in there.
I am hooking the load..
I am working the cement bucket.
What is who can be directly in the fall zone of a suspended load?
saddle me right, torque me, suspend me, torque me again.
What is how do I install a wire rope clip?
I am only 80% percent efficient
what is the wire rope clip?
Horizontalsling angle of 25degrees
what is a horizontal sling angle that a qualified person shall be consulted?
sling length/hook height x share of the load=
What is how do you calculate tension factor or sling angle factor?
raise that boom
Give the signal!!!!
I gave a design factor of 4 and I must be removed from service at 1000 degrees.
What are Alloy chain slings. 450 degrees automatic reduction in capacity. 1000 remove from service.
All lifts have a potential for this?
Rigging Failure , Bound shackle , Load slippage
Two blocking, rope breaking
What is shock loading or unloading?
I have four legs but
What is slings are rated at a three leg capacity. The fourth leg wanders from one leg to the other as it is moved through the air maintaining stability? It is physics baby.
I am moving a load up and down an inclined plane.
What is must always have a restraint system when moving a load. Always approved by a qualified person?
I am winding my rope on a winch or drum.
What is up up , down down. To prevent an angle of wire from stressing the winch or drum motor.
Load on a sister or duplex hook.
What is always balanced between hooks?
10 broken wires.
What is removal criteria for a wire rope sling?
I have three sling eyes.
What is attach to a shackle bow or saddle no more 120 degrees of included angle?
Used to lift long objects, increasing horizontal sling angle. And approved by a qualified person.
What is a lifting or spreader beam?
My sister……….hook……..has a hole.
What is the pin. The hole is for the pin, of the shackle, with one strap.
