The four main types of slings are:
- Wire Rope: The most commonly used sling.
- Chain: Combines superior strength, ease of handling and durability.
- Mesh: Wire and Chain.
- Synthetic: Both web and round-slings are used where loads must be protected from damage.
.
Just so, what determines which type of sling you use?
There are four primary factors to consider when safely lifting a load. They are (1) the size, weight, and center of gravity of the load; (2) the number of legs and the angle the sling makes with the horizontal line; (3) the rated capacity of the sling; and (4) the history of the care and usage of the sling.
Likewise, which of the following are the most commonly used rigging materials? Discussed under are some of the most common rigging hardware.
- Blocks & Pulleys. These are widely used across the rigging industry for lifting exceptionally heavy objects.
- Eye Bolts.
- Rigging Hooks.
- Wire ropes & accessories.
