American Cube Mold's Pro-Loader multi-use load frames feature many component options, allowing design of a versatile system to meet your application needs. These frames can often perform all load tests required in a laboratory with only a quick change of component sets. All frames have 3/4hp DC motors and controllers to precisely regulate strain rates to +_ 1% of set point. The sturdy 14-gauge painted steel cabinets are built for demanding laboratory environments. Cross-head heights are quickly and accurately changed using adjusting nuts. The coarse-threaded vertical rods are plated for corrosion resistance and flexible boot protects the precision loading screw from dust and dirt. Units operate on 115V/60Hz power supplies. Add "F" suffix to model numbers for units operating on 230V/50Hz.
Component sets are required and purchased separately. Standard component sets include an appropriately rated load ring and dial indicator, and digital component sets include a load cell and linear displacement transducer. Digital component sets can be connected to a user-supplied computer for transfer of data in ASCII file format. Load Frame Component sets and individual accessories are listed separately.
HM-396, HM-397 Pro-Loader and HM-398 Pro-Loader II 10,000lbf (44.5kN) capacity load frames are designed for multiple applications in efficient, cost -conscious soil testing laboratories. All can be used for CBR, unconfined compression and triaxial testing on soil or soil-cement samples. The Pro-Loader AA has extended capabilities for Marshall testing of hot-mix asphalt specimens.
Loading rates are easily selected from the push-button control panel with digital display. Travel limit switches with indicating lights protect the unit from damage due to platen travel outside of its 3in (76mm) range. A 60-3/4in (171.5mm) diameter lower platen is included. Cross head height is quickly and accurately changed using the self-centering adjusting nuts. The vertical rods are 1.25in (31.8mm) diameter.
The HM-396 Pro Loader strain rate ranges from 0.001in-0.1in (0.0254-2.54mm) per minute. A high-speed platen advance rapidly positions the platen for efficient testing. The HM-397 has a wider range, from 0.0001in-.3in (0.00254-7.623mm) per minute, and is a better choice for more extensive soils applications, including some triaxial testing. The mircro-stepping drive controller allows more precise control of loading rates. The HM-398 Pro-Loader II has a higher strain rate to accommodate Marshall and Lottman testing of hot-mix asphalt specimens, while still allowing many soils tests to be performed. The range is 0.02in-2.0in (0.508-50.8mm) per minute. This unit does not use a high speed platen advance Est Ship Wt.:240lb (109kgh). |
