OMS hydraulic clamps provide a safe connection between the vibratory piling machine and the pile by using a piston locking system. They are manufactured from special alloy casting steel and have two gripping jaws fixed and moveable. Moveable jaw is connected to hydraulic cylinder with bolts. This cylinder operated by pressured oil up to 350 bar. With the help of pilot operated check valve, keeps the clamp cylinder under pressure. Hydraulic cylinder is controlled by control pendant or control panel. SCN clamps are used to drive or extract sheet beams and double or single sheet piles. KCN Clamps are used for tube piles. ACN clamps are used for wooden piles.
