W型锁式接链环只可用于立环使用，由于采用了不与链轮接触的立式连接，所以可以防止链轮由于制造误差对接链环造成的损坏，提高了接链环的使用寿命。W型锁式接链环可以与D级链条配合使用。

W lock connectors are designed specially for joining the mining chain in weld chain link.It does not need directly engaged with the sprocket which may cause abrasion to the link .This kind of connector can be fitted with chain connector in Grade 100 and leads the longer work life.

W 型锁式接链环机械性能表

“W型锁” 接链环是可用于连接圆环链和“紧凑”链，在制造过程中选择了富含Cr 、Ni、Mo原色的高合金钢原材料和多重热处理工艺，具有非常高的拉伸性能和疲劳寿命。

这种接链环只可垂直使用，其外形大小符合DIN22258 Part3 标准要求，并经精心设计，确保与配套链轮的配合。

“W型锁”接链环的重量比其他类型接链环较轻。

W-lock connectors have been designed specially for joining together Mining chains .The tensile and fatigue performance is particularly impressive and has been achieved by careful seletion of raw materail containing Cr. Nr.Mo and heat treatment during the manufacturing process.

The connectors which are for use in the vertical plane only are produced dimensionally in accordance with DIN22258 Part3 and are extremely sprocket friendly where these have been designed with this specification in mind .W-lock connectors are lighter in weight compared with the equivalent chainlock connector.
