300,000lbf Auto Concrete Compression and Flexural Machine

Gilson 300K Automatic Concrete Compression and Flexural Machine

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

The Gilson 300,000lbf Rigid Frame (RF) Series Automatic Concrete Compression Machines combine advanced technology, exceptional durability, and unmatched precision for laboratories with intensive daily testing requirements. Designed specifically to handle high-strength concrete mixes, these machines are built with highly rigid load frames to ensure consistent, safe, and repeatable testing even under extreme conditions. The design exceeds ACI 363 recommendations, making it a reliable choice for professionals in the construction and materials testing industries.

Key Features at a Glance

• Exceptional Rigid Frame Design: The machine's high longitudinal stiffness minimizes elastic deformation during loading, reducing wear on components and prolonging service life. This design also decreases explosive sample failures caused by rebound in unbonded capping systems.
• Advanced Hydraulic System: The bottom-mounted hydraulic cylinder applies upward loading force through a dust-protected flexible sleeve, ensuring precise and reliable performance.
• User-Friendly Automation: The automated controller simplifies the testing process. Operators only need to input specimen data and test type, position the sample, and press a button to start the test. The machine handles the rest—specimen contact, load application, pre-load and test rates, break detection, and piston return.
• Real-Time Data and Reporting: Force, stress, and rate of load are continuously displayed during the test cycle, with real-time graphing of load vs. time or stress vs. strain available. Data can be transferred through USB, LAN ports, or Wi-Fi, and stored with detailed test information like lab ID, sample ID, and client details for error-free reporting.
• Quiet, Energy-Efficient Drive System: The integrated electric motor and hydraulic pump use electronic feedback to maintain precise loads and rates. This state-of-the-art system operates at lower motor speeds, reducing noise and wear, and ensuring consistent performance regardless of oil temperature or other factors.
• Enhanced Safety Features: Welded steel frame safety doors with heavy-duty latches and shatter-resistant Lexan® inserts fully enclose the test chamber, protecting operators from flying debris while reducing dust and noise during testing.

Designed for Versatility and Efficiency

The RF Series machines are configured for a wide range of testing needs. Supplied ready to test standard 6x12in (152x305mm) concrete cylinders with unbonded neoprene capping pads, they can also be outfitted with accessories for testing:

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

For labs performing advanced testing, custom models like the AC-300M and AC-300MR are available. These versions are factory-configured to perform ASTM C469 modulus of elasticity (MOE) tests, with an optional proportional valve for controlled piston retraction and LVDT inputs required to measure MOE and Poisson's ratio. These specialized models can still perform standard compression, flexural, and splitting tensile strength tests using the same components.

Superior Data Management

The advanced controller simplifies the testing workflow and enhances data management:

• Collect and transfer data easily via USB, LAN, or Wi-Fi.
• Store important test data such as lab ID, client details, and sample specifications for streamlined reporting.
• Export test results directly to a PC or print summaries with a single button.

Reliable Performance Under Pressure

The RF Series machines operate on a precise hydraulic system designed for maximum reliability. Feedback-regulated hydraulic components ensure consistent load applications and eliminate pressure variations caused by oil overheating or other factors. This system is both energy-efficient and durable, extending the service life of hydraulic components.
