Load Frame, CBR (California Bearing Ratio) Automatic

Supports the following standards: ASTM D1883

CBR/LBR Specific Automatic Load Frame
ASTM D1883; AASHTO T193; BS 1377 Part 4
Humboldt provides these two Elite Series Load Frames for doing CBR and LBR applications.

The HM-5150A Load Frames has been specifically designed to handle CBR and LBR applications. Its heavy-duty design and precise stepper-motor control provides a stable platform for years of reliable service. From educational institutions and consulting firms to high-volume commercial labs and construction projects, the HM-51150A Load Frame can perform these applications with ease.

Like all Elite Series Load Frames, the HM-5150A is built around Humboldt‘s integral, data logger with touch-screen control, which allows the load frame to be used as standalone device capable of full test control and data logging, as well as controlled from a network computer.

Standalone Control
The waterproof, touch screens featured on these load frames provide a colorful, at-a-glance monitoring of testing functions without the use of a computer. Operators can see all the data in several formats at the machine during the testing procedure. Test data can then be transferred to a computer for use with Humboldt‘s NEXT Software for report generation.

Computer Control
Humboldt‘s Next software is included with the all Elite Series Load Frames. This software provides robust machine control, data acquisition and report generation for those using a computer to control testing operations.

In addition, operators have the ability to view and control testing operations from a PC in the lab, in the next room or at a different location, while also providing report generating capabilities using NEXT software and the test-specific software modules.

A CBR-specific software module is available for use with the NEXT software, which provides CBR-specific setup and formatting, rather than the generic formatting provided with the basic NEXT software.

The HM-5150A is sold as a Load Frame ONLY, refer to the accessories tab above for items needed to perform CBR tests.
