CBR (California Bearing Ratio) Automatic Load Frame

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

The HM-5150A is built around Humboldt’s integral, data logger with touch-screen control, which allows the load frame to be used as a standalone device capable of full test control and data logging. Humboldt’s Next software and HM-5001SW Next test-specific CBR/LBR software module are included with the HM5150A load frame. This software provides robust machine control, calibration, data acquisition and report generation for those using a computer to control load frame operations. In stand-alone mode, the HM-5150A load frame provides a 7″ (178mm) touch-screen controller. These new waterproof, touch screens provide 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 while the test is running. Data can then be viewed simultaneously or downloaded later to a computer in the lab, in the next room or at a different location, while also providing report generation capabilities from within Humboldt’s NEXT software enhanced CBR and LBR-specific software module

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.
