Hook claw seat directly to do with the thread pitch forward and back of the operation handle before and after minor swing hydraulic starter lever forward, knuckle corresponds to the back, pulled an object pulled out. 
 The role and function descriptions 
 A new hydraulic Rama easy to operate, and effort. 
 2 jaw type with two claw the scene working to replace them. 
 3 can rotate freely, according to the the Rama distance the center of the piston, and soon encounter pulled workpiece center point. 
 (4) can be any optional pump. 
 The use of flexible, light weight, small size, easy to carry, suitable for factories, ship repair places ideal tool. 
 Hydraulic pull at most, with the parameters of the machine series
