Sling as a tool, especially for lifting large objects, we must check the sling regularly to ensure safety. Here is a simple way to check the sling with you.
Sling as a tool, especially for lifting large objects, we must check the sling regularly to ensure safety. Here is a simple way to check the sling with you.
1. Check whether the sling marks are lost or damaged or the contents are identified due to defilement, etc. You may think this is unnecessary, but it's the most important thing. It's easy to blur some marks at this point because we use the sling to make it greasy. Because the markings clearly indicate parameters such as maximum bearing ultimate stress, it is easy to cause various accidents if we use them directly without identifying them. We use the sling first of all to distinguish between the various types of sling, so that you can be divided into categories of use.
2. Check whether some fasteners such as bolts and nuts are loose. This is the most common case, we must carefully check before use, to ensure that the sling can be used safely.
3. Wear, corrosion, crack (including weld), plastic deformation and other abnormal conditions of the main stress members of the metal structure;
4. Main parts and components, such as hook (including hook nut anti-release device with straight handle), lug (trunnion), drum, fixed connection of wire rope and rope end, pulley, clamping spreader pliers arm (including claw and lifting tooth). Wear, corrosion, plastic deformation, crack and other abnormal conditions such as lifting rod of metallurgical feeding cranes, rotating lock of container spindles, coupling of power transmission device, reducer, open gear, roller chain, screw shaft, etc.
