450,000lbf Auto Concrete Compression and Flexural Machine

Gilson AC-450, 450K Automatic Concrete Compression & Flexural Machine

AC-450 Series Fully Automatic Concrete Compression Machines

The AC-450 Series Automatic Concrete Compression Machines are high-performance, precision-engineered systems designed for rigorous concrete strength testing. With a total load capacity of 450,000 lbf (2,002 kN), these machines are built to exceed ACI 363 requirements for rigidity, ensuring reliable and consistent results for a wide range of sample types, including concrete cylinders, beams, cubes, and cores. Ideal for testing laboratories and industries where accuracy, efficiency, and compliance with ASTM, AASHTO, and other global standards are critical, the AC-450 Series delivers cutting-edge features to simplify and enhance the testing process.

Performance and Efficiency Built In

The AC-450 Series machines are fully automated and require minimal operator input, significantly improving productivity while reducing the potential for errors. Testing is initiated with a single touch on the intuitive touchscreen controller after selecting the test method, sample type, and parameters. The machine automates specimen contact, pre-loading, load rate application, break detection, data collection, and piston reset, ensuring compliance with all selected test requirements. This level of automation eliminates variations in testing procedures, guaranteeing precise and repeatable results.

Designed with user convenience in mind, the touchscreen interface also displays real-time test information, including force, stress, and load rate. For advanced analysis, users can view real-time graphs of load vs. time or stress vs. strain. Data can be exported seamlessly via Wi-Fi, USB flash drive, or LAN connectivity for comprehensive reporting and documentation. The diagnostics feature provides instant feedback on system health, covering emergency stops, data communication, hydraulic pressure, and more, ensuring the system is always ready for operation.

Advanced Hydraulic and Drive Systems

The AC-450 Series incorporates a next-generation drive system that operates quieter, cooler, and more efficiently than traditional systems. The integrated electric motor and variable-speed hydraulic pump maintain consistent pressures to meet program demands, preventing overheating and extending the service life of hydraulic components. The machine's top-mounted piston is strategically positioned to avoid wear from accumulated debris, ensuring long-term durability and precise operation.

Safety and Durability

Operator safety is a top priority for the AC-450 Series. Key safety features include an emergency-stop button, hydraulic safety relief valve, piston over-travel limit switch, and see-through fragment guard doors. These safeguards ensure a secure testing environment, even during high-capacity compressive strength tests. The rugged, welded steel load frame provides exceptional rigidity and durability, meeting the demands of even the most intense testing conditions with ease.

Comprehensive Testing Capabilities

This model is designed as a standard load frame for compressive and flexural strength testing. It can be further customized with a variety of accessories to expand capabilities, accommodating additional test methods and sample types for broader applications. The machine is equipped with a 6x12in (152x305mm) cylinder test set for use with unbonded neoprene caps and steel retainers, enabling precision testing of samples up to 12,700 psi (87.6 MPa).
