Gilson 400,000lbf Rigid Frame (RF) Series Automatic Concrete Compression Machines

The Gilson RF Series Automatic Concrete Compression Machines are designed for laboratories with heavy daily testing demands and high-strength mix testing, offering exceptional durability, precision, and efficiency. Built with rigid steel frames that ensure superior stiffness, these machines provide accurate and repeatable results while reducing fatigue on components, making them ideal for long-term, high-volume use. Whether you’re conducting standard compressive strength tests or more advanced modulus of elasticity (MOE) and Poisson’s ratio testing, the RF Series delivers reliable performance every time.

Key Features

• Exceptional Frame Stiffness: The rigid load frames minimize elastic deformation during loading, extending the service life of the machine and reducing the frequency of sample failures caused by capping system rebound. The lateral stiffness also compensates for minor misalignments, ensuring consistent and repeatable results.
• Advanced Automation: The automated controller streamlines the testing process. After entering specimen data and selecting the test type, operators simply position the sample and press a button to start the test. Multiple specimens can be tested without re-entering data, saving time and effort.
• Precise Regulation: The electric motor and hydraulic pump automatically regulate force application, rate of load, pre-load, and test load rates, eliminating variations caused by operator error or procedural discrepancies. This ensures accurate and repeatable results every time.
• Real-Time Data Display and Storage: Force, stress, rate of load, and real-time graphs (load vs. time or stress vs. strain) are displayed throughout the test. Testing data, including laboratory ID, sample ID, and client information, can be stored and exported via USB, LAN, or Wi-Fi for easy data management.
• Energy-Efficient Operation: The state-of-the-art drive system operates with lower motor speeds, reducing noise, heat, and energy consumption while maintaining precise performance. Hydraulic components are protected from wear caused by overheating, ensuring a longer lifespan.
• Safety Enhancements: The machine features welded steel frame fragment guard safety doors with heavy-duty latches and shatter-resistant Lexan® inserts, protecting users from debris while providing a clear view of the testing process. Emergency off switches and other safety mechanisms ensure safe operation at all times.

Applications

The RF Series is equipped to handle a wide range of tests, including:

• Compressive strength tests on 6x12in (152x305mm) concrete cylinders, with a maximum strength of 11,300psi (77,914kPa).
• Flexural beam strength tests.
• Splitting tensile strength tests.
• Modulus of elasticity (MOE) and Poisson’s ratio on 4in or 6in (101mm or 152mm) concrete cylinders (specific models with optional components).
• Testing of cube specimens, core samples, and cylinders with ground ends or sulfur mortar caps.

Advanced MOE Testing Configuration

The AC-400M and AC-400MR models are pre-configured for ASTM C469 modulus of elasticity (MOE) and Poisson’s ratio testing. These models feature a unique manifold, an optional proportional valve for controlled piston retraction, and LVDT inputs to measure strain. This setup allows for accurate determination of MOE and Poisson’s ratio while still accommodating standard compressive, flexural, and splitting tensile strength tests. Compressometer and extensometer testing fixtures for MOE and Poisson’s ratio are available separately.
