NOMENCLATURE, FUNCTIONS AND CAPABILITIES DESCRIBED. THREE MAIN SHIP'S GEAR CATEGORIES OUTLINED; CARGO HANDLING GEAR AND USES REVIEWED.
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

CHAPTER 4
CARGO-HANDLING GEAR
4-1. INTRODUCTION. Cargo-handling gear is used to secure cargo while it is being raised or lowered by the ship's gear. It also moves cargo to and from its stowage position in the ship. Proper training in the selection and use of cargo-handling gear is necessary for safe and efficient cargo operations. As terminal operations coordinator, you are responsible for training and supervising your personnel in the methods prescribed by this chapter.
4-2. GENERAL-PURPOSE GEAR. General-purpose gear is used with many types of cargo. This type of gear includes-
Endless slings.
Single slings.
Combination slings.
Chain slings.
Canvas slings.
The ends of slings are usually made up into eyes, either with or without thimbles. The eyes fit on the cargo hook and attach to the drafts or loads of cargo. By these eyes, a sling is joined to another sling, a hook, or a ring, either directly or by using a shackle. Thimbles in the eyes strengthen the sling by protecting it from sharp bends around pins, hooks, shackles, links, rings, and similar objects...
a. Endless Slings. Splicing the ends of a piece of wire or fiber rope makes an endless sling. It is simple to handle and can be used in several different ways to lift loads. The endless sling is most commonly used as a choker hitch. When the endless sling is used as a choker, personnel pass it around the draft or cargo forming a loop on top of the draft. The other end is passed through this loop, pulled tight and attached to the cargo hook. To balance the load, personnel spread apart the two parts of the sling on the bottom of the draft.
(1) The endless sling is also used with chime or running hooks. It may be used as a basket sling or a vertical sling (Figure 4-2).
(2) Personnel should not use endless slings to lift bagged cargo such as sugar, flour, and cement. These types of items require canvas slings...
