A document that outlines weights, crane configuration and rigging requirements for a lift is called
a: - ANS-Lift plan
\A lift plan MUST be completed by a: - ANS-Supervisor
\A load will be moved using both a Manitowoc 4100W and a Grove TM 1500. Determine which
configuration of each crane will be best suited to perform the multiple crane lifted as described
using figure Man4100_Grove1500 load charts. Calculate the load on both cranes #1 and #2
then choose the appropriate answer below. Load radius at pick 35 feet, load radius at placement
45 feet. Load weight is 118,000 lbs. Dimension A=20 feet and B=40 feet. Each Beam Clamp has
a weight of 500 lbs. - ANS-Crane #1 Manitowoc 4100W-S2 with 200 feet of main boom and a
100 ton block installed. Crane #2 Grove TM 1500 with 118 feet of main boom, with a 30 ton
block installed.
\A one-inch, 3 leg bridle wire rope sling, rigged at 35' angle, is good for 18 tons. The addition of
a fourth leg will increase your capacity by: - ANS-0 lbs
\According to ASMEB30.5,a two crane lift is signaled by: - ANS-One designated person
\According to the table, what is the MINIMUM clearance a crane in operation can be from a 250
(kv) energized power line? - ANS-20 feet
\After any structural repair of modification, a personnel lifting platform shall be tested to what
percentage of the platform rating? - ANS-150%
\All of the following are reasons for stopping personnel lifting and operations EXCEPT: -
ANS-There are no TAG LINES
\All of the following are results of unbalanced reeving of the hook block EXCEPT: - ANS-Wear
on the hook
\All of the following conditions exert dynamic loading on a crane EXCEPT: - ANS-Static boom
angle
\All of the following statements about crane contact with power lines are TRUE EXCEPT: -
ANS-The operator should leave the cab quickly as possible
\An unsafe condition that riggers should be aware of when dealing with a multi part load block
is: - ANS-Twisting multi part lines
\Anchorage points for fall arrest for a single person MUST be able to hold: - ANS-5000 lbs
\At what percentage of increase in length should a change sling be removed from service? -
ANS-5%
\Before a spreader bar or beams can be used they must have been: - ANS-Tested and
approved
\Before performing pick and carry operations with any mobile crane, it is important to: -
ANS-Refer to the manufacturer's capacity chart
\Calculate the block load for block B in the drawing? - ANS-24,000 kbs
\Calculate the block load for block C in the drawing? - ANS-12,000 lbs
\If both fists are placed in placed in front of your body with your thumbs pointed outward, the
crane operator should: - ANS-Extend the boom sections
\If the jacket of a synthetic round sling is damage, that sling should be: - ANS-Removed from
service immediately
\In a spur-gear chain hoist with a two chain system, the endless chain is used to: - ANS-Raise
and lower the load
a: - ANS-Lift plan
