LBR Load Frames

Gilson’s Load Frames offer solid performance in Limerock Bearing Ratio tests in accordance with Florida FM-5-515 and other testing applications. Five models are available in strain rates that range from 0.001—0.1in/min to 0.02—2.0in/min.

Models have a capacity of 10,000 or 20,000lbf (44.5 and 89kN) with 11.9x37.3in (302x947mm) WxH frame openings. Platen diameter is 8in (203mm). Controllers regulate strain rates to ±1% of the set point. Sturdy, 16-gauge painted steel enclosures have adjusting nuts on the 1.25in (32mm) coarse-threaded rods to quickly adjust the horizontal cross-head height.
