A small-footprint, triaxial-specific load frame that provides the versatility, precision and durability found throughout Humboldt's elite series load frames.

The HM-5020 Triaxial Loader has been specifically designed to handle triaxial testing applications, including: UU, CU and CD triaxial and UC. From educational institutions and consulting firms to high-volume commercial labs and construction projects, the Triaxial Loader can handle any application with ease. Its heavy-duty design and precise stepper-motor control provide a stable platform for years of reliable service allowing the HM-5020 to perform any tests required up to its load capacity of 3000 lbf (15kN).

Like all elite series load frames, the HM-5020 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.

It can also be controlled by a networked computer at any location with access to the network.

The HM-5020 provides four (4) integral and independent data acquisition channels, which can be utilized in stand-alone configurations or accessed through a LAN-networked computer using Humboldt's Next Software.The HM-5020 load frame is built with durable, high-quality components and features the use of a stepper motor, precision gears and gear box to ensure smooth and reliable operation, as well as precise results.

In stand-alone mode, the HM-5020 load frame provides a 7" (178mm) touch-screen controller, giving you finger-tip control of your testing processes, as well as providing real-time, visual views of your data in both tabular and graphic formats. This waterproof, touch screen provides 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 or our enhanced test-specific modules.


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 up to 4 different tests at the same time
  • Calibration of channels to load cells, transducers and other suitable instruments
  • 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.

When operated from a networked computer the NEXT software provides robust machine and test control, as well as report generation. It also provides the ability to control and monitor multiple machines from a single computer.

Humboldt's NEXT software provides:

  • 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
  • Advanced, test-specific modules are available, which provide all the calculations and graphs required per testing standards
  • 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.
