Tiedowns

Tiedowns are devices and methods used to secure an object to prevent movement during storage or transport. They are used on trailers, trucks, aircraft, ships, and temporary structures to restrain loads from shifting or becoming airborne.

Common types include straps or webbing (nylon or polyester) with ratchet or cam buckles, chains with hooks and binders, and rope lashings. Straps are versatile and easy to use; chains offer high strength and durability; ropes are useful for light loads or improvised setups.

Key components include anchor points or tie-down rings, edge protectors to prevent strap damage, hooks or ratchet mechanisms, and tensioning devices. Proper use involves placing straps around solid parts of the load, using multiple tie-downs to distribute force, and keeping runs straight and flat to minimize slippage and edge wear.

Standards and safety: tiedowns have rated capacities, such as working load limit (WLL) or safe working load. Do not exceed the rating, and inspect equipment before use for wear, fraying, cracks, or corrosion. Replace damaged items. Avoid knots in straps, do not overtighten, and use edge protection and proper spacing between tie-downs.

Applications: in road transport, tiedowns secure pallets, machinery, and vehicles on trailers; in aviation, they restrain aircraft on ramps; in construction and outdoor events, they stabilize temporary structures and tarps.

Maintenance and training: users should follow manufacturer guidance, check compliance with local regulations, and ensure operators are trained in safe tying practices and load distribution.
