MIL-S-52124B(ME)
3.20 Lifting attachments.  Each screening unit and each sectionalized
component shall be provided with permanently attached lifting attach-
ments (see 3.16.2 and 3.16.3).  The attachments shall enable the screening
unit and each sectionalized component to be lifted in its normal traveling
or operating position.  The attachments shall be located so that not
less than l-inch clearance is maintained between the slings and all ex-
terior parts of the screening unit or each sectionalized component being
lifted.  Spreader bars are permitted.  Each attachment shall be of suffi-
cient strength to carry not less than 2-1/2 times the normal load im-
posed on the attachment.  Attachments for multiple slings shall be lo-
cated so that the attached slings will converge not more than 19 feet
above the lowest extremity of the load.  Attachments shall be positioned
so that the lifting strain will be in line with the longitudinal axis
of the eye of the attachment.  The inside diameter of the eye shall be
riot less than 3 inches.  Attachments shall be attached to members of
sufficient strength to withstand stresses in the amount and direction
of pull specified for the attachment.  Where required, reinforcements
shall be used to meet the requirements  specified herein.  Lifting attach-
ments may also be used as tiedown attachments when such attachments
meet the requirements specified in 3.21.
3.21 Tiedown attachments.  Each screening unit and each section-
alized component shall be provided with integral attachments to per-
mit tiedown of the screening unit or sections to the floor or deck
of' the transportation medium (see 3.16.2 and 3.16.3). The tiedown
attachments shall withstand dynamic thrusts encountered during trans-
port, and static loads of 8G-forward, 8G-rearward, 2-1/G-upward, and
l-1/2G-sideward where G equals the maximum shipping weight of the
screening unit or each sectionalized component.  Each attachment and
structural member to which the attachment is fastened shall withstand
its proportion of the static load without permanent deformation or
breakage.  Attachments shall be rounded and beveled to prevent cutting
of tiedown material.  Tiedown attachments may also be used as lifting
attachments when such attachments meet the requirements specified in
3.20.
3.22 Identification marking.  The unit shall be identified in accord-
ance with MIL-STD-130.  The marking shall be applied to the unit on
plates conforming to MIL-P-514, type I, style 1, composition C, of type
I, grade A, class 1 material.  Plates shall be attached by screws, bolts,
or rivets in a conspicuous protected location.
3.22.1 Shipping data plate.  Shipping data plate shall conform to
MIL-P-514, type III, composition C, of type I, grade A class 1 material
