WAW series (Dual space) Servohydraulic universal testing machine is ideal for high-capacity tension, compression, bend/flex, and shear testing. It accords with the relative requirements of EN, ISO, ASTM, JIN, GB, BS and many other testing methods. These frames feature dual spaces so users can quickly change between tension and compression testing without having to remove heavy fixtures.
HUALONG WAW has long been recognized as the standard for accuracy, dependability and versatility in servo-hydraulic universal testing machines.
Extra-length screws and columns, with an adjustable lower crosshead, to increase the available test space for longer test specimens.
Semi-open front hydraulic wedge clamps for easier loading and allowing rapid loading and unloading of specimens.
Rigid load frame either in 4-column construction providing superior axial and lateral stiffness and minimum maintenance, low reaction at specimen failure.
Lower crosshead movable to increase distance between grips
Servo valve attached direct on actuator providing close-coupled servo valve and accumulators for improved performance and reduced pressure fluctuations
With digital displacement transducer for the best positioning and measuring accuracy
Hydraulic operated wedge grips available
Including grip control system mounted direct at the machine
Tooling for tension, compression, bend/flex, shear, and other tests.
Application range:
metals-(wire, rod, tube, strip, plate, strip),
fasteners (tensile, proof, single and double shear),
construction materials (reinforcement bar, wire, mesh, folding, compression of concrete) and components)
and more
