HM-5030.3F Load Frame, Master Loader, Elite Series, CBR/LBR

Humboldt MasterLoader CBR/LBR Solution
Designed for applications requiring multi-purpose loading systems, such as road construction projects in either mobile or fixed labs, educational institutions and consulting firms, the HM-5030 Master Loader is ideal for just about any application from road construction to high-volume commercial and educational laboratories.


While the HM-5030 has been specifically designed for soil testing labs conducting multiple testing operations including: UU, CU and CD triaxial, UC, CBR and LBR, it is also perfect for running Marshall, Hveem, TSR and SCB asphalt tests as well. Its heavy-duty design and precise stepper-motor control provide a stable platform for years of reliable service allowing the HM-5030 to perform any tests required up to its load capacity of 11000 lbf (50kN).

Like all Elite Series load frames, the HM-5030 is built around Humboldt‘s integral, 4-channel 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. It can also be controlled by a networked computer at any location with access to the network.

In stand-alone mode, these load frames provide 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 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 or our enhanced test-specific modules.

Stand-Alone Control
Humboldt’s touch-screen controller provides you with full, graphical monitoring of all testing functions in a stand-alone application, while maintaining full computer control when desired.

Now you can have full, finger-tip control and monitoring of all testing functions with Humboldt’s touch-screen controller, found on Humboldt’s Elite Series Load Frames. This seven-inch, waterproof screen provides at-a-glance monitoring of testing functions, in a real-time graphical display, without the use of a computer, building upon Humboldt‘s dedication to modular, stand-alone data acquisition.

Now, in a stand-alone application, you will be able to run tests and display results while viewing tabulation, basic x-y graphs and instrument readings in real-time during the test, using user-defined, basic data acquisition. Test data is stored in the device and can be downloaded to a USB drive via the machine’s FRONT USB port or the data can be transferred to a computer via the LAN port.

A second USB port located on the back of the machine can also be used to power a wireless access point, which can provide a wireless hook-up with a computer, if no LAN is available.

Touch-Screen Controller provides:

  • 4-channel data acquisition
  • Hi-res, 7″, waterproof, touch-screen provides total control and real-time graphical display of tests
  • Machine/Test control and data acquisition via touch-screen
  • Control all channels at the same time
  • Calibration of channels to load cell and transducer
  • Real-time graphical chart and numerical display of tests via touch-screen display
  • Effective sampling rate of 50 readings per second
  • Stores up to 1000 tests with 3000 points per test
  • 2 USB ports. One in front for data transfer and the rear port is for powering a wireless access point.

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.

So, whether you are controlling a single load frame, controlling multiple machines or even a complete geotechnical lab, Humboldt‘s NEXT software, in conjunction with Humboldt‘s Elite Series Load Frames provide a complete solution for acquisition, recording and presentation of testing data in data tabulation and graphic chart formats.

  • Machine control, and data acquisition via networked computer
  • Provides the ability to use Next Software’s, advanced test-specific modules
  • Real-time graphical chart and numerical display of tests via computer display
  • Effective sampling rate of 50 readings per second
  • Stores unlimited tests with up to 3000 points per test.
  • Up to 255 individual tests can be run simultaneously from a single PC
  • Provides advanced graphing capabilities
  • Provides full-unit customization
  • Reports can also be exported to Excel or a CSV file, if desired, and, we can provide custom integration/export solutions for LIMS, EQuIS, gINT, etc.
