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 five 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 0.05 to 2.00000 (0.00001 to 50.80000 mm/min). This speed range is more than adequate for the majority of standard soil tests. The HM-2850 can also be used for asphalt Marshall and TSR testing and features a rapid travel speed of 2.25 in/min. for moving the platen into position quickly.
