Gilson RF Series Automatic Concrete Compression Machines: Built for Heavy-Duty Performance

The Gilson 400,000lbf Rigid Frame (RF) Series Automatic Concrete Compression Machines are engineered for laboratories handling high-strength concrete mix testing and heavy daily workloads. With a focus on safety, precision, and durability, these machines are designed to meet the rigorous demands of modern testing environments. Featuring an exceptionally stiff load frame, advanced automation, and user-friendly controls, the RF Series delivers consistent, accurate results with minimal operator effort.

Why Choose RF Series Compression Machines?

The RF Series stands out for its exceptional frame rigidity, designed to reduce elastic deformation during loading cycles. This minimizes fatigue on critical components, prolongs service life, and ensures reliable, repeatable results. Additionally, the reduced likelihood of explosive sample failures—caused by unbonded capping systems—is a key benefit of the RF’s design. The lateral stiffness of the frame also corrects for minor sample misalignments or inconsistencies, ensuring uniform testing.

These machines exceed the recommendations outlined in ACI 363, making them ideal for laboratories focused on high-performance concrete testing.

Key Features

• Advanced Automation for Easy Operation: The automatic controller requires minimal operator input. Simply enter the specimen details and test type, position the sample, and press a button to initiate the cycle. For multiple tests of similar samples, data entry is only needed once.

• Built-in Precision Control: The electric motor and hydraulic pump work together to regulate force and load rate with precision. This ensures compliance with ASTM and AASHTO standards, eliminating discrepancies caused by operator error or load inconsistencies.

• Real-Time Data Display & Storage: During testing, force, stress, load rate, and real-time graphs are displayed on the touchscreen interface. Data, including laboratory ID, client information, and sample details, can be stored and shared via USB, LAN, or Wi-Fi.

• Quiet & Energy Efficient: The state-of-the-art drive system operates at lower motor speeds, making it quieter and more energy-efficient than older designs. Hydraulic components are optimized for long service life without being affected by pressure or oil temperature variations.

• Enhanced Safety Measures: Welded steel fragment guard doors with Lexan® inserts provide full enclosure of the test chamber, protecting operators from flying debris and reducing noise and dust. The system includes instant fault detection for piston overtravel, hydraulic safety relief issues, and emergency stops.

• Versatile Testing Capabilities: Each machine supports a variety of tests, including compressive, flexural, splitting tensile strength, modulus of elasticity (MOE), and Poisson’s ratio. Optional accessories allow for testing a wide range of specimens such as concrete cylinders, beams, cubes, cores, and more.

Innovative Modulus of Elasticity Testing

For advanced testing needs, RF Series machines can be factory-configured for ASTM C469 modulus of elasticity (MOE) and Poisson's ratio testing. These models include a unique manifold, optional proportional valve for piston retraction control, and support for one or two LVDT inputs. Fixtures such as compressometers or extensometers (sold separately) are required for these tests.
