Tie down straps (also called lashing straps or tie downs) are fasteners
used to hold down cargo or equipment during transport. Tie down straps
are essentially webbing that is outfitted with tie down hardware. This
hardware allows the tie down strap to attach to the area surrounding the
cargo or equipment, loop over the cargo or equipment, and/or attach to
the cargo or equipment. It usually also includes a method of tensioning
the strap, such as a ratchet.
Two common types of tie down straps
are loop straps and two-piece straps. Loop straps, like their name
implies, are a single piece of webbing that is looped around the item to
be protected and the two endpoints are brought together at the tie down
fastener for fastening and providing tension.Two-piece tie down straps
are a single assembly that is constructed out of two separate pieces of
webbing each with their own hardware that are fastened at one end to the
area surrounding the equipment to be protected and connect to each
other, typically at the fastener.
The main advantages of ratchet
lashings are :
1. Load restraint using a tensioning device (ratchet)
2. Effective and safe control of loads whilst transportation
Extremely quick and efficient tie down and release of load thus saving
4. No damage to the load being tied down.
