The Express line of machines is a bold new approach to servohydraulic machines for static testing. Manufactured to exacting standards, these machines are accurate, tough and cost less than conventional hydraulic testing machines. Express machines are designed for performing tensile tests on wire, strapping, fasteners, sheet material, bar stock and rounds. With appropriate fixtures they can be used for compression testing. They are available in capacities ranging from 50 to 600 kN (11,250 to 135,000 lb f). Express testing machines feature digital closed loop control of the machine's servo valve and can be operated under load, strain or position servo control. (
