这种接链环只可垂直使用，其外形大小符合DIN 22258 part 3标准要求，并经过精心设计，以确保与配套链轮的配合。 “V型锁”接链环的重量比其它类型接链环较轻。V型锁式接链环装配一定要注意装配方向，保证箭头方向与传动方向一致。
V lock connectors have benn designed specially for joining together Mining chains of either round like compact con-figuration .the tensile and fatigue performance is particularly impressive and has been achieved by careful selection of raw material and heat treatment during the manufacruring process.
the connectors which are for use in the vertical plane only are produced dimensionally in accordance with DIN22258 part 3 and are extremely sprocket friendly where these have been designed with this specification in mind.
V lock connectors are lighter in weidht compared with the equivalent chainlock connector .Notice the direction when link the Vlock connector with the chain .Keep the arrow in the connector align with the direction of the transmission.
