Gilson Pro-Loader Load Frames by Karol-Warner are adaptable for a wide range of laboratory soil tests such as Unconfined Compressive Strength, California Bearing Ratio (CBR), Soil Cement and Triaxial testing. This series of load frames is designed to work with a variety of digital and analog sets and other ancillary products, ensuring each user can create a test system that meets specific testing needs. A simple change of components easily adapts the unit for different soil testing applications. 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). Units run on 3/4hp DC motors and controllers regulate strain rates to ±1% of set point. Sturdy, 14-gauge painted steel enclosures have adjusting nuts on the 1.25in (32mm) coarse-threaded rods to quickly adjust the horizontal cross-head height.
HM-399 Pro-Loader Load Frames feature a 20,000lbf (89kN) load capacity and a precision strain rate of 0.00001—0.3in/min (0.000254—7.62mm/min), allowing for testing of sensitive soils. The micro-stepping motor and drive controller precisely control load rates. Dimensions are identical to other Pro-Loader frames.
