Load Frame, Multi-Speed for Triaxial Testing

Supports the following standards: ASTM D1883, ASTM D2850, ASTM D2166, ASTM D4767, ASTM D1559; AASHTO T193, AASHTO T296, AASHTO T297, AASHTO T208, AASHTO T245, AASHTO T246; BS 1377: Part 4: 1990, BS 1377: Part 7: 1990, BS 1377: Part 8: 1990, BS 598: Part 107

The HM-2850 Multi-speed Load Frame is designed for those who want a high-quality, but simple, multi-purpose load frame without built-in data acquisition capabilities. The HM-2850 is ideal for applications where the operator is either not concerned with data acquisition; or, already has or is planning to construct their own data acquisition system. With its large 7" color, touchscreen, the HM-2850 provides the operator with the ability to precisely select any speed with four decimal accuracy within the machine‘s speed range.

The HM-2850 features a quiet, direct drive stepper motor that provides a range of loading speeds from 0.00001 to 2.00000 in/min. This speed range is more than adequate for the majority of standard soil tests. The HM-2850 also incorporates a separate, dedicated control to accommodate 2.00 in/min. for use in Marshall and TSR Testing, as
well as a rapid travel speed of 2.25 in/min for moving the platen into position quickly. Speeds are controlled through the use of edit keys and the digital display.

Features Include:

  • 8" platen provides roomy, stable base for test equipment
  • Backlit LCD display
  • Test speeds adjustable from 0.0001 to 2.00000 in/min. via keypad
  • User selectable unit change between U.S. standard and metric from keypad
  • Preset Marshall/TSR test option
