Product Overview
Serrated link connectors are used to join vertical or horizontal mining round-link chains and can also be employed in scraper conveyors and coal plows. The selection of special materials and tight dimensional tolerances ensure that these serrated connectors are not only easy to install but also deliver performance that exceeds the requirements of the MT/T 99–1997 standard.
Assembly and Maintenance
+ Ensure the installation surface is clean.
+ Ensure that both elastic pins are fully inserted.
+ Suitable for both horizontal and vertical installation
+ Inspect every three months or after completing 1 million tonnes of coal transportation (if used for a reloader, inspect monthly).Technical Specifications
