A complete selection of components ensure the frames can be outfitted to run a variety of laboratory soil tests. Most frames offer 10,000lbf (44.5kN) capacities, while select models have options for 20,000lbf (89kN) capacities.
- 7611 Load Frame, 0.001 – 0.1in / min, 10,000lbf (44.5kN) capacity is a versatile frame that is an optimal choice for small labs and schools to perform a variety of soil tests.
- 7621 Load Frame, 0.0001 – 0.3in / min, 10,000lbf (44.5kN) capacity uses a micro stepping drive controller to set strain rates to ±1% and can permit a 1000:1 strain rate reduction.
- 7631 Load Frame, 0.00001 – 0.29999in / min, 10,000lbf (44.5kN) capacity offers the widest range of slower strain rates to cover many different soil tests.
- 7731 Load Frame, 0.00001 – 0.29999in / min, 20,000lbf (89kN) capacity has the strain rate range of model 7631 with a larger, 20,000lbf capacity.
- 7691 Load Frame, 0.02 – 2in / min, 10,000lbf (44.5kN) capacity can be configured for use with asphalt Marshall testing.
