HVG LINK CHAINS 0031

HVG LINK CHAINS 0031: Short Link Lifting Chain

The short link lifting chain is manufactured to meet requirements of GB/T 20946-2007 and ISO 1834:1999. It is divided into five series according to mechanical properties of finished chains. The five series are as follows: M(4), P(5), S(6), T(8), V(10). HVG Marine is able to offer all above-mentioned chains including calibrated chains and common chains. All chains provided by HVG Marine are of high quality and 100% proof tested. The short link lifting chain is mainly used for lifting purposes in industry, and it is also can be used as chain sling. The available types of short link lifting chains are shown below:

Short link lifting chain, grade 4, non-calibrated
Short link lifting chain, grade 6, non-calibrated
Short link lifting chain, grade 8, non-calibrated
Fine-tolerance hoist chain
Calibrated short link chain
