Technical Information

Brief Introduction

High strength chain rigging is linked by metal chain, which can be divided into two types: Welded and assembled chain sling. Meanwhile, it can be divided into single limb and multi limbs in terms of structure. It is made of premium alloy steel with good wear-resisting quality. The outstanding advantage is to resist abrasion, resisting high temperature, resist causticity, low elongation and without stretch when stressed. The sling is adapted to use in large-scale and frequent occasions. The flexible multi limbs structure and multiple assembling forms can improve the work efficiency and reduce the cost.
