Heavy-duty steel frames feature 10,000lbf (44.5kN) capacities with some models having options for 20,000lb (89kN). Large frame openings are easily adjustable on heavy threaded rods for a variety of sample configurations. 3/4hp DC motors and controllers precisely regulate strain rates to ±1% of set point. These versatile units are quickly adaptable for other popular soil tests with easy change-out of components. Models are available with options for full load, speed and direction control through user’s PC.

• 7611 Load Frame, 0.001 – 0.1in / min, 10,000lbf (44.5kN) capacity is a great choice for smaller labs and universities that need to perform a variety of soil tests.
• 7621 Load Frame, 0.0001 – 0.3in / min, 10,000lbf (44.5kN) capacity has a micro stepping drive controller and can achieve a 1000:1 strain rate using simple push-button settings.
• 7631 Load Frame, 0.00001 – 0.29999in / min, 10,000lbf (44.5kN) capacity features the widest range of strain rates and a 10,000lbf capacity to accommodate different soil tests.
• 7731 Load Frame, 0.00001 – 0.29999in / min, 20,000lbf (89kN) capacity has the same broad range of strain rates as Model 7631, but features a 20,000lbf capacity.
• 7691 Load Frame, 0.02 – 2in / min,10,000lbf (44.5kN) capacity has sufficient range for a number of soil tests, and can also be used for Marshall Stability testing of hot-mix asphalt samples.
