Description

Supports the following standards: ASTM D1883, AASHTO T193, BS 1377 PART 4

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 M&L Testing Equipment’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. M&L Testing Equipment’s Next software is included with the HM5150A load frame. The HM-5001SW Next test-specific CBR/LBR software module is sold separately. 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 M&L Testing Equipment’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 M&L Testing Equipment’s NEXT Software for report generation.

Computer Control
M&L Testing Equipment’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.
