Donghua USA hoisting chain includes our standardized leaf chain series and multi-plate pin chain, as well as our parking garage chain and special leaf chain for stackers.  Each adopts high wear-resistant pin carburizing technology and/or pin through hardened technology in order to increase its impact resistance.  An example is the special leaf chain for container stackers which has high wear resistance and fatigue performance in order to  meet the requirements of high-load and continuous operation conditions.
