c. Dynamic Test.
NOTE
Dynamic test is performed with a test load of
100% of crane rated load on Range Diagram for
this boom extension and radius. The overload
protection system should not prevent lifting of
this test weight.
(1) Extend boom (1) to 16 feet, 0 inches.
(2) Position boom (1) approximately 15 for a load radius of
15 feet, 6 inches.
(3) Connect 2200 lb test weight (2) to crane hook (3).
(4) Raise test weight (2) approximately 18 inches with hoist
(4).
(5) Record dimension A, distance test weight (2) is from
ground.
(6) Record dimension B, extension length of jack cylinders
(5).
(7) Shut down engine (TM 9-2320-366-10-1).
(8) Allow MHC to remain undisturbed for 30 minutes.
NOTE
Maximum allowable drift of jack cylinders and
test weight is one inch in 30 minutes.
(9) Measure dimension A, distance test weight (2) is from
ground.
(10) Measure dimension B, extension length of jack cylinders
(5).
(11) Start engine (TM 9-2320-366-10-1).
(12) Rotate test weight (2) to left and right and back to center
line.
(13) Lower test weight (2) to ground with hoist (4).
(14) Disconnect 2200 lb test weight (2) from crane hook (3).
d. Follow-On Maintenance
