6.11 Deletions. Types A, B, H, and K hoists, forms A and B, and grade designations for hand
and load chains have been deleted from this specification for the following reasons:
a. Hoist types A and B: Their function can be accomplished by the type C hoist which is
more efficient and has a greater range of hoist capacities. There is little demand by the
military activities for these items.
b. Type H wire rope hoist: Survey of military activities showed little demand for wire rope
ratchet hoist; the type H chain hoists duplicate the function, and provide for greater range
of hoist capacities.
c. Form A and B and grade designations for hand and load chain have resulted in conflicting
requirements for hoist design. Specifying requirements for non-sparking, non-corrosive
chain and hooks cannot be justified for manual hoist operation. Steel and corrosion-
resisting coatings have been specified for load and hand chain and for hooks.
