Gilson 300,000lbf Rigid Frame (RF) Series Automatic Concrete Compression Machines

The Gilson RF Series Automatic Concrete Compression Machines are engineered for precision, durability, and reliability, making them ideal for laboratories handling heavy daily testing demands and high-strength concrete mixes. These machines combine advanced automation with a highly rigid load frame that exceeds ACI 363 recommendations to deliver consistent and repeatable results for a wide range of concrete testing applications.

Designed for laboratories that require exceptional performance, these machines reduce operator input, improve efficiency, and ensure accurate testing of concrete cylinders, beams, cubes, and other test specimens. Here's an overview of what makes the RF Series stand out:

Advanced Rigid Frame Design

The rigid load frames are specially constructed to provide unmatched longitudinal stiffness, minimizing elastic deformation during testing. This reduces assembly fatigue, prolonging service life and enhancing machine reliability. The stiff frame design also reduces the frequency of explosive sample failures caused by unbonded capping systems' rebound and corrects for minor sample misalignments or inconsistencies, ensuring accurate and reproducible test outcomes.

The frame features bottom-mounted hydraulic cylinders with protective flexible sleeves to prevent dust contamination and provide upward loading force for safe and reliable operation.

Automated Controller for Effortless Testing

The automatic controller streamlines the testing process, requiring minimal operator input.

• Simply input specimen data and the desired test type on the touchscreen.
• Position the sample and start the test cycle with a single button press.
• For multiple specimens of the same type, repetitive data entry is eliminated.

The advanced drive system precisely controls load application and rates, ensuring compliance with ASTM and AASHTO standards. The system eliminates variations in load application and reduces operator error, guaranteeing reliable, repeatable, and documented results for every test.

Real-Time Data Monitoring and Reporting

During testing, the machine continuously displays force, stress, and load rate on the touchscreen, with real-time graphing of load vs. time or stress vs. strain. Data collection and reporting are simplified with built-in USB ports, LAN ports, and Wi-Fi connectivity, allowing for easy transfer of test results to a PC or network. Laboratory ID, sample ID, and client information can also be stored for error-free reporting and distribution.

For added convenience, the system can print or export summary reports directly from the interface.

Enhanced Safety Features

Safety is a top priority in the RF Series. The welded steel frame includes innovative fragment guard safety doors with heavy-duty latches and hinges. Shatter-resistant Lexan® inserts provide a clear view of the testing process while protecting operators from flying debris. The enclosed test chamber reduces dust and noise, enhancing the overall testing environment.

The diagnostics page on the touchscreen continuously monitors the loading, safety, and communication systems, instantly displaying warnings for any issues, such as emergency stop activation, piston overtravel, or hydraulic safety valve operation. Test cycles cannot begin until all fault notifications are resolved, ensuring safe operation at all times.

Energy-Efficient Hydraulic System

The integrated electric motor and hydraulic pump are feedback-regulated for precision and efficiency. The system operates at lower motor speeds, reducing noise and energy consumption while maintaining consistent performance. The advanced hydraulic system prevents accuracy issues caused by overheating or pressure variations, extending the service life of hydraulic components.

Versatile Testing Capabilities

The RF Series is equipped to test 6x12in (152x305mm) concrete cylinders with unbonded neoprene capping pads in steel retainers, handling strengths up to 8,500psi (58,608kPa). Optional accessories are available to expand the machine's capabilities, allowing it to test:

• Cylinders with ground ends or sulfur mortar caps
• Flexural beams
• Cube specimens
• Core samples
• Splitting tensile strength specimens

For advanced applications, the AC-300M and AC-300MR models can measure ASTM C469 modulus of elasticity (MOE) and Poisson's ratio. These configurations include a unique manifold, optional proportional valve for controlled piston retraction, and inputs for LVDTs required for MOE and Poisson's ratio testing. Compressometer or extensometer fixtures are sold separately.
