EHW SERIES

Double Point Straight Side
200-1600 ton

Sutherland’s EHW plunger-style Double Point Straight Side Presses are by far the most heavy-duty presses available, engineered under the most demanding and exacting standards to deliver unmatched power and precision on the toughest jobs. The EHW is built with a tie rod design frame, using thicker steel members to ensure reliable rigidity and stability. Complementing the sturdy frame is an advanced drivetrain, featuring a back-to-front drive with an eccentric gear drive and double pitmans. These pitmans, one on each side of the eccentric gear drive, align and equalize the tonnage on the pitman journals. The lower sections of the pitmans are connected to plunger guide suspension points for precise, vertical, non-rotational tonnage delivery. Altogether, this unique drivetrain ensures higher rating points and faster speeds without compromising on raw power. The EHW series comes standard with Sutherland’s software-based I-Press AB+ control system with Connected Enterprise capabilities.
