Rope and Chain Study Guide

Load or Chain Binder

Device with handle, offset links, and grab hooks that tightens load-binding chain when the handle is pulled.

Double Loop Chain

Lightweight metal chain with small, closely linked oval or round links sold by the foot, used for hanging light fixtures and other suspended loads requiring secure support.

Proof Coil Chain

Welded link chain made from low carbon steel, sized by link diameter, used for tie-downs, towing, logging, and general utility applications.

Repair Link

Metal chain connector used to repair broken links or attach hooks and rings, with an open-and-close design that secures quickly for reliable field repair.

Sash Chain

Lightweight metal chain with small, closely linked oval or round links sold by the foot, used for hanging light fixtures and other suspended loads requiring secure support.

Twist Link Chain

Chain with twisted links designed to move smoothly over surfaces without snagging, used where free travel is required.

Eye and Eye Swivel

Connector made of two chain links joined by a riveted pin, allowing rotation to prevent twisting in chains or cables.

Clevis or Shackle

U-shaped forged metal connector with a removable pin or bolt across the open end, used to secure chains, cables, or implements for pulling and lifting.

Grab Hook

Forged steel hook with a deep curved throat and narrow opening designed to catch a single chain link, holding securely under tension when tightened.

Slip Hook

Round hook attached to log chain allowing it to slide along the chain for adjustable positioning and secure load handling.

Lashing Straps

Polyester or nylon straps used to secure loads, typically 10,000–20,000 lb strength, used with winches for tightening.

Winch

Ratcheting device used to tighten ropes or lashing straps, providing controlled tension for securing and moving heavy loads.

Chain Hoist

Manual lifting device using chain mechanism to raise heavy loads, available in capacities ranging from 1/2 to 5 tons.

Cotton Rope

Soft natural fiber rope with low strength compared to other fibers, used for light-duty tying, bundling, and general-purpose applications.

Manila Rope

Twisted natural fiber rope made in three or four strands, stronger than cotton but weaker than synthetic ropes for general use.

Nylon Rope

Synthetic rope made as twisted or braided construction, stronger than polypropylene, durable for heavy-duty applications but not suitable for hand braiding.

Rope Thimble

Curved metal groove-shaped fitting placed inside a rope eye loop, used to reinforce and protect cable or rope from wear while maintaining a secure loop under load.

Twisted Polypropylene Rope

Synthetic rope that melts near heat, commonly called trucker’s rope, typically black with orange stripe, used for light to medium tie-downs.

Wire Rope

Steel cable made of twisted wires, coiled or uncoiled like a hoop, used for lifting, towing, and heavy-duty rigging applications.

Wire Rope Clamp

Clamping devices used to secure wire rope ends, available as U-bolt with cleat or bolt clamp for forming secure loops.

Bowline

A reliable knot that creates a fixed loop at the end of a rope, commonly used for securing, lifting, or rescue applications.

Clove Hitch

A simple hitch used to secure a rope to a hook, post, or rail, providing quick attachment and adjustment.

Eye Splice

A rope-splicing technique that creates a permanent loop in a laid rope, providing strong, secure attachment points.

Sheet Bend

A dependable knot used to join ropes of different diameters, creating a secure connection for extending or combining lines.

Square Knot

A common and versatile knot used for joining two ropes, creating a secure and balanced connection under light loads.

Trucker’s Hitch

A versatile hitch used for securing loads, providing mechanical advantage to tighten ropes and maintain tension effectively.
