Fully Automatic Low-Capacity Compression Machine has a load capacity of 60,000lbf (266.9kN). It is designed for compressive strength testing of 2x2in (51x51mm) cubes, flexural strength testing of 4x4in (100x100mm), and 6x6in (150x150mm) beam specimens.
Its automated test cycle is initiated with a single button on the touchscreen controller. The machine controls specimen contact, pre-loading, rate of load, break detection, data collection, and return of the piston to the home position following specified requirements for the selected test method.
Selection of the test method, sample type, specimen data, and test parameters are made on the touchscreen of the controller. Force, stress, and rate of load are displayed simultaneously during a test, with an option to show real-time load vs time or stress vs strain graphs. Load rate and applied force are precisely regulated by feedback during sample loading. USB and LAN ports, along with Wi-Fi capability, allow immediate printing of tests or easy data collection and transfer to the user’s PC for reporting of results using a USB flash drive.
A menu button prints each test or transfers test data in summary form. Testing laboratory, sample ID, and client information are stored for error-free reporting and distribution. The diagnostics feature instantly displays the status of the emergency-stop button, drive system, data communication, pressure transducer, and over-travel limit switch. An indication of a fault condition in any of the systems must be resolved before testing can proceed.
The energy-efficient integrated electric motor and hydraulic pump operate at variable speeds to achieve and maintain required pressures based on loading program demands. This state-of-the-art drive system is dramatically quieter, eliminates pressure variations from over-heated oil, and extends the service life of the hydraulic components.
The rugged, welded steel frame exceeds ACI 363 requirements for system rigidity and has a total capacity of 60,000lbf (266.9kN). Excessive long-term wear to the hydraulic loading system is prevented by mounting the piston on the top of the frame, where it is unaffected by accumulated test debris. An emergency-stop button, hydraulic safety relief valve, piston over-travel limit switch, and fragment guard door ensure safety for the operator while running tests.
AC-60 units are supplied ready for compression strength testing of 2x2x2in concrete cubes and may be outfitted with accessories to accommodate additional testing. The included 2in Cube Test Set consists of a pedestal with a hardened steel top bearing surface and an upper platen assembly with a locking stem.
