Company’s new 3500 Power Unit is designed to be used in high-volume, high-speed, pre-stressing operations. It has an advanced, energy-saving variable displacement pump that reduces heat build-up in the hydraulic fluid, intuitive controls and components protected with safety relief valves. Beyond its precision, product engineers note, the unit is easy to calibrate: Prestress production field tests have verified that after initial loading, final load is typically reached on the first pull, requiring no additional correction.— Hamilton Form Co., 817/590-2111; [email protected]
