The MK105 MOD O hoisting sling (multi-leg pole pendant) consists of a pendant assembly and separate leg assemblies. The pendant assembly has a spliced eye at each end, a stiffening tube and a braided nylon rope. The leg assembly is a braided nylon rope with spliced eye at one end and a thimble and safety hook at the other end. Up to six legs may be attached to the lower pendant eye by means of choker hitches. The long legs are color coded green and the short legs are color coded orange.
The slings are used in vertical replenishment for transfer of all types of cargo.
The MK 89, 90, 91, and 92 hoisting slings consist of braided nylon rope providing a lifting eye at one end for helicopter attachment and thimbled safety hook at the other for load attachment. The upper portion of the pendant has a reach tube to permit raising the lift eye to the aircraft slings hook. The slings are color coded; MK89 red, MK90 aviation orange, MK91 green, and MK92 bright green. The basic difference is in the length of the reach tube and rope.
The slings are used in vertical replenishment at sea.
The sling assembly is used with the 2-1/2" auxiliary rig to support the 2-1/2" fueling at sea hose beneath the probe assembly. It is connected to the probe assembly by the u-bolts.
The aircraft engine transfer sling assembly consists of a pear link with two wire rope assemblies. Each wire rope assembly is connected to an adjusting link. A 7/8" safety anchor shackle connects the sling to the aircraft engine container. It is used in conjunction with the cargo stream strongback for underway replenishment of aircraft engines.
