1.Product details: Pneumatic anchor cable and back tension machine is combination of eletric hydraulic pump and back anchor tension Jack. Jack can complete these automaticly: seize the anchor, load tension, boost and lock anchors under the drive of hydraulic pump,since the poewr sourse is High pressure emulsion and there is no electric utility,so explotion-proof function is very well. especially used in the work of releasing the prestress of the roof for coal and tunnel,solve the caving problem quickly in the goaf and wind in and out area.

3. Features: The operated valves have the functions of maintaining the hydraulic load and keeping the load step by step. The force indicator shows the value of output force directly. The jack cylinder is made of premium alloy steel which can support high pressure and have huge tension. The design of anchor’s grasping claws are reasonable, the surface is processed by Carbonitriding. It seizes the anchor firmly and smoothly and long service time. The set of equipment work smoothly, operate easily and maintain simply.
