crane test

Side loading can occur when: - ANSThe crane is out of level, during rapid swing, dragging or
pulling loads sideways, improperly performed tilt-up operations, or high winds

Crane's leverage - ANSCrane weight times the horizontal distance from the center of gravity to
the tipping axis

Load's leverage - ANSThe horizontal distance from the center of gravity of the load to the
tipping axis times the load weight

Margin of stability for crawler mounted cranes - ANS75%

Margin of stability for carrier mounted cranes - ANSOn outriggers extended 85%
On rubber or tires 75%

Margin of stability for commercial boom trucks - ANS85%

Backward stability factors - ANSOperating over the side, no load, shortest boom length
maximum boom angle, and load on wheels

Overloading the crane will cause: - ANSCrane tipping or structural failure

Capacity charts are normally divided by: - ANSUsing a bold line, asterisks, or shaded area

Structural strength is found on the top or bottom of the capacity chart - ANSTop

Stability is found on the top or bottom of the capacity chart - ANSBottom

What component can fail when operating in the structural area of the capacity chart - ANSWire
rope, boom, block, sheave, boom extension cylinder, boom lift cylinder, ring gear, hydraulic
hoses, outriggers, jib, jib pendants, jib mast, boom pendants,...

If boom length is between chart listings you should: - ANSAlways use lower capacity of the next
longer or shorter boom length

Load radius is: - ANSThe horizontal distance from the center of rotation to the center line of the
hook

If load radius is between chart listings you should: - ANSUse the next longer radius

, Boom angle is: - ANSThe angle between the center line of the base boom and the horizontal
after the load is lifted

Boom deflection will: - ANSDecrease boom angle and increase load radius

Tire deflection will: - ANSIncrease the load radius and decrease the boom angle

If boom angle is between chart listings you should: - ANSUse the next lower boom angle

Gross capacities are: - ANSThe rated capacities listed in the capacity chart

What may need to be deducted - ANSWire rope, ball, jib, load block, rigging, net load, stowed
jib, EXT., AUX. Boom head,...

When do you deduct weight of the crane's hoist rope - ANSWhen the manufacturer specifies in
the load chart, when the crane is reeved with more then the minimum parts of line required,
when the crane is reeved with hoist line not being used to make the lift, or when there are parts
of line below the ground

Net capacity is: - ANSGross capacity minus capacity deductions for load handling devices

Gross load is: - ANSThe net load plus the attachments, lifting devices, hook, blocks, balls, wire
rope, and Rigging

Net load is: - ANSThe actual weight of the item being lifted

Dynamic loading is: - ANSThe forces created by movement

Total load is: - ANSThe combined forces produced by the actual load weight, lifting attachments,
and the movement of the load and attachments

Capacity is limited by: - ANSThe lowest rated component

Parts of line is: - ANSThe number of hoist ropes directly supporting the lower load block

SWL means: - ANSSafe working load

How do you find the minimum parts of line required - ANSAdd the weight of the hook block, the
rigging, and the net load.
Divide the suspended weight by the safe working load of the hoist rope

The range diagram can be used to: - ANSDerive the approximate distances when planning lifts
and determining crane configuration, ect.
