KNOWING SITES & MAKING REAL MACHINE
Hyd. pump and motor are set to create high level of pressure but it should go up gradually until rock or concrete reach to breaking momentum. Then highest level of set pressure hits up for a while.
This system construction is realized by our long experience from real sites and studies on materials.
All details of machine, even very little touch, come from our know-hows which are rooted in trying and stories, - success and failure.
