小型液压捣固机均需设置夹轨钳。其作用是使捣固机在作业时不会抬起或掉道;使镐掌能克服道碴阻力顺利下插,以保证捣固机的作业效率和作业质量,因此它是捣固机的一个重要部件。按轨钳与钢轨的作用部位不同,夹轨钳大体可分为:轨底式、轨顎式、轨底轨顎组合式和轨侧式四种。 Small hydraulic tamping machine need to set rail clamp. Its role is to make the tamping machine in the operation will not lift or off the road; make the pick palm to overcome the ballast resistance successfully inserted in order to ensure the tamping machine operating efficiency and quality of operations, it is a tamping machine Important parts. According to the role of rail clamps and rail parts, clamp rail clamp can be divided into: rail-based, rail jaw, track rail at the end of the rail combination and rail four.
