Hydraulic System

Scotchman Industries announced recent improvements to three models of ironworkers. The new hydraulic system that is being installed in several of the Scotchman Dual Operator ironworkers has increased the machine's cycle time by over 40 percent. The change now makes the DO machines even more efficient.

The hydraulic system for these machines is designed to assure full hydraulic pressure and speed to both operators, meaning one worker can be operating the punching station while another worker runs a different tooling station without delay.

"Our goal is to provide the best machinery for our customers and help them find profitable solutions for their shop needs," explains Scotchman owner Jerry Kroetch. "We had concerns that our dual operator machines were simply not fast enough. Our old hydraulic system pumped 6.42 gallons per minute. Now, our new pumps have increased to 9.06 GPM."

Dual Operator Ironworkers are generally more expensive and may require more floor space than single operator units, but the price difference is quickly diminished with the higher productivity achieved. Since more than one worker can be operating multiple stations at the same time, both production capacity and efficiency can increase simultaneously.

Scotchman's Dual Operator 120 ton, 135 ton, and 150 ton machines have all received the improved hydraulic system and are now capable of achieving a 41 percent increase in cycle time. Cycle time is measured from the moment the foot pedal is pressed to start making a punch until the punch is complete and the machine returns to its resting state.

Each machine features a versatile tool table design with standard punch, angle shear, flat bar shear, and notcher. In addition to providing a superior hydraulic system, Scotchman Industries has numerous accessories available including custom-made tooling and punches and dies.
