400,000lbf Auto Concrete Compression and Flexural Machine

400,000lbf Auto Concrete Compression and Flexural Machine

Gilson 400,000lbf Rigid Frame (RF) Series Automatic Concrete Compression Machines are designed for laboratories handling heavy daily testing demands and high-strength concrete mix evaluations. Built with an exceptionally stiff load frame, these machines ensure safe, reliable, and precise performance, surpassing the recommendations of ACI 363. Engineered for durability and accuracy, the RF Series is ideal for conducting concrete compression and flexural strength tests with minimal operator input.

Exceptional Frame Design for Superior Testing

The RF Series boasts high longitudinal stiffness, minimizing elastic deformation during loading cycles. This reduces fatigue on the assembly, prolonging the machine’s service life and significantly decreasing the risk of explosive sample failures caused by unbonded capping systems. The lateral stiffness of the frame improves consistency by offsetting minor sample misalignments and internal inconsistencies, ensuring accurate and repeatable results.

Effortless Automation for Efficiency

The automated controller simplifies operation, requiring minimal input from users. After entering specimen data and test parameters, the machine takes over. Position the sample, press a button, and let the RF Series complete the test cycle. It’s that easy. For labs handling multiple specimens of similar types and sizes, repetitive data entry is eliminated, saving valuable time.

Compliance with ASTM and AASHTO Standards

The RF Series allows users to tailor test specifications to meet ASTM or AASHTO requirements. Operators can control every aspect of the testing process, including:

• Specimen contact
• Pre-load and test load rates
• Break detection
• Data collection
• Automatic piston return to the home position

Advanced machine feedback ensures precise regulation of force and load rates, eliminating operator error and discrepancies in testing procedures. This ensures superior accuracy and repeatability in every test.

Advanced Data Collection and Sharing

Real-time data, including force, stress, load rate, and graphical representations of load vs. time or stress vs. strain, is displayed throughout the test cycle. The RF Series is equipped with built-in USB and LAN ports, along with Wi-Fi capability, allowing seamless data transfer and sharing. Whether you need to store data locally or quickly share it with clients or colleagues, the system makes it simple and efficient.

Energy-Efficient and Reliable Hydraulic System

The RF Series features an advanced electric motor and hydraulic pump system. This state-of-the-art drive system:

• Maintains precise loads and load rates based on programmed inputs
• Operates quietly at lower motor speeds
• Reduces energy consumption
• Optimizes hydraulic component lifespan Temperature fluctuations or pressure variations, such as those caused by overheated oil, do not affect its accuracy or consistency, ensuring reliable performance even under demanding conditions.

Enhanced Safety Features

Safety is a top priority with the RF Series. The machine includes welded steel frame fragment guard safety doors with heavy-duty hinges and latches. These doors fully enclose the test chamber, reducing noise and protecting operators from flying debris. Shatter-resistant Lexan® inserts provide a clear view of the testing process while keeping users safe. The touchscreen diagnostics page monitors the status of the loading, safety, and communication systems, instantly displaying warnings for any issues, such as emergency stops or piston overtravel. All faults must be resolved before testing can resume, ensuring safe operation at all times.

Versatility for a Wide Range of Specimens

The RF Series is supplied with a 6x12in (152x305mm) cylinder test set designed for use with unbonded neoprene capping pads in steel retainers. Additional accessories are available for testing:

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