1. CHAINLOCK connectors have been specifically designed for joining together Xtra quality mining chain and have compatible strength. This is 25% greater than connectors designed for use with DIN quality grade 2 chain of either round or flat link configuration. This Xtra performance has been achieved through careful choice of materials and heat treatment whilst keeping the dimensional properties within those specified in DIN 22258: 2003 part 2. This will ensure that the connectors-which must be installed in the horizontal plane of the chain only-will safely negotiate sprockets that have been designed in accordance with this specification.
CHAINLOCK connectors can also be used with DIN quality grade 2 chains having the advantage of higher strength thus giving an additional factor.
2. Bi-Lock Connectors (for vertical and horizontal use)
Bi-Lock connectors have been specifically designed to join together round link chains in either the horizontal or vertical plane, allowing the connectors to be used in both AFC and plough haulage system applications.
Special material selection combined with close tolerance matching ensures the connector is easily assembled and has a strength greater than the minimum requirements of chain to DIN22252/2 of a comparable size.
3. V-Lock Connectors (for vertical use only)
V-Lock Connectors have been specifically designed for joining together mining chains of either round link or compact configuration and have strength 10% greater than connectors designed for use with DIN quality grade 2 chain.
Improved performance has been achieved by careful selection of the steel which is unique and special heat treatment during the manufacturing process. Each connector is additionally differentially heat treated to ensure the connector side hardness level is limited to a maximum of HB 363. This ensures maximum resistance to potential rubbing cracks and also further enhances the fatigue life performance.
V-Lock connectors are only for use in the vertical plane and dimensionally in accordance with DIN 22258: 2003 Part 3. They are extremely sprocket friendly and are lighter in weight compared with the equipment Chainlock connector.
