FAQs
1. What are lifting slings made of?
Lifting slings can be made from various materials, including steel wire, alloy steel, nylon, polyester, and high-tensile steel.
2. How do I determine the right load capacity for a lifting sling?
Always choose a sling with a load capacity higher than the maximum weight of the load you intend to lift, accounting for safety margins.
3. Can synthetic slings be used in harsh environments?
Synthetic slings are generally not recommended for extreme temperatures or exposure to chemicals, as they can degrade under such conditions.
4. What is the difference between a choker hitch and a basket hitch?
A choker hitch wraps around the load and tightens as it is lifted, while a basket hitch supports the load from underneath, providing more stability.
5. How often should lifting slings be inspected?
Lifting slings should be inspected regularly, ideally before each use, to ensure they are in good condition and free from damage.
