Steel Rack Testing Systems
UTSP-0450
Static testing machines below have double acting pistons with force capacities of 1000 kN, 500 kN and 100 kN. Static testing actuators can be controlled by a single hydraulic power unit. Different than the static testing machines Utest manufactured 10 Hz. cyclic testing capable 50 kN dynamic testing machine for dynamic and fatigue behavior of the connections at steel storage racks systems.
Electrical parts as indicators, system management buttons and controller is involved in the power pack. Bladder type accumulators are supplied with the pack in order to compensate pressure drops while actuator is operating and any pressure losses between the HPU and test station, in order to smooth pump ripples. Oil level, oil temperature, filter's condition and motor temperature are continuously checked by controller and system has necessary interlocks for fault conditions. Factory –set pressure relief valve prevents excessive increases in pressure. Compact designed power pack saves valuable floor space in your lab. Installed isolation manifold lets the pack running multiple test stations, preventing over pressurization, discharging system pressure separately and power isolation of the stations.
These systems are for testing different type of
storage-shelves as Bending Tests on Beam End Connectors, Looseness Test on Beam End Connectors, Shear Tests on Beam End Connectors, Stub Column Compression Tests, Compressive Tests on Uprights, Bending Tests on Upright Position and Bend Tests on Beams.
Steel rack testing systems are controlled by a computer with the free of charge software uSta and uDyna. uSta and uDyna are flexible and user-friendly windows based application software for static and dynamic testing. In the software
user can also create custom test sequences. Synchronized 100 Hz data transfer from feedback signals supplies detailed recording of running tests. This rate is flexible up to 4 kHz if the application is applicable. Graphical and numeric monitoring is displayed real time in the user interface. The software also includes an easy calibration check facility. The machine gives some constant load values and waits there for easy check mechanism. Furthermore uData is also delivered to customer freely, where data analyzing and reporting operations will be handled.
