“链锁”式接链环是专门为连接“标准”型圆环链和“紧凑”链而设计。其外形大小符合DIN22259 Part2 1983标准的要求，在制造过程中选择了富含Cr、Ni、Mo、合金元素的高合金钢和多重热处理工艺，以确保“链锁”式接链环（只可安装于水平使用）与配套链轮的“”配合，安全运行。固定螺钉经过防腐处理，利于拆除。链锁式连接环中间块固定有三种形式，用户可根据安装习惯、工况自行选择。

Chain lock connectors have been designed specially for joining together Mining chains of either standard or Xtra quality.This performance has been achieved through careful choice of materials and heat treatment  whilst keeping the dimension properties for the mechanical joint within DIN 22258 part 2 1983.This ensure that chain lock connectors -which must be installed in the horizon-tal plane of chain only-with safely negotiate sprockets that have been designed with this speciation and requirement in mind. The Securing screw is anti-corrosion to assist in removal .Three methods of fixing the Spacer lock can be selected according to the assembly habit or working condition.
