  • 40 Ton Air over Hydraulic H-frame Press

  • Heavy-Duty adjustable support frame with a variety of fixtures and attachments to attaching
    loads to.

  • 50,000 Load Cell with a digital load display calibrated with the load cell

  • Speed of ram controlled by air valves.

  • Dial indicators monitor movement

  • All tests are video recorded and saved

  • Results shown on video are recorded on to Excel Workbooks

  • Pounds of force are recorded for each 10/1000 inch movement

  • Graphs visually compare multiple tests for each configuration
   
  • Steel Bars are used for testing because strut channels fail before the
    QuakeClamps

  • Special Beam fixtures made to provide passage of push-bar through
    the center.

  • Clamps attach to the bottom where the push-bar applies force
    exactly in the center of the member held by the clamps.

  • Movement of end of the member being held is monitored by dial
    indicator

45 Degree Fixture - Concurrent  Vertical and Longitudinal Loading
Benefits
NuClamp Test Press
  •        Fixture designed to attach clamp assembly on the bottom of a
    beam on a 45 degree slope.  

  •        This applies force vertically and longitudinally at the same time
Cantilevered Torsion Loading
  • This fixture allows force to be applied longitudinally to
    determine resistance for the clamp and strut channel assembly
    to slide along a beam.


  • It was found that a simple setscrew added to the middle of the
    hook area significantly increase resistance of the assembly
    sliding down the beam


  • Another way to prevent sliding is to place weld bumps on the
    edge of the flange for the clamp bodies to bump against





  • No stops are added on this example

  • This setup measures the cantilevered force that
    the clamp         assembly will hold.  

  • This is how real world torsion is likely to be
    encountered

  • Cantilevered load to 1595 ft. Lbs.  Measured from
    edge of beam.
Longitudinal Loading
  •        This fixture allows force to be applied in a transverse
    direction. This determines the resistance for the  strut channel
    to slide through the clamp assembly

  •        Simple effective methods using common hardware has     
    been found to greatly reduce movement.

  •        A simple strut nut, square washer and bolt is added to this
    example
