  • Page 16: Tripod

    5.0 Tripod The Triax Tripod is shown in Photo 3. In addition to the three leg section attached to the top of the tripod, nine snap together sections of legs are provided with the Tripod to allow a maximum drop height of up to approximately 12 feet (drop height is measured from the bottom of the missile to the top of the surface to be tested.)
  • Page 17 CAUTION! Erecting the tripod can be a hazard due to tipping. To erect the tripod, two persons are recommended. Use of proper head protection is also suggested, as the operating height of the tripod will, in most cases, be above the head of the operators exposing them to the hazard of being struck by either the head form or the tripod.
  • Page 18 Properly connected leg section with pin fully extended INCORRECT connection – pin not fully extended Three of the nine leg sections feature a rounded end. These must always be installed as the lowest leg sections when the Tripod is erected. Whenever connecting leg sections the Tripod must first be laid on a horizontal surface.
  • Page 19 The locking handle is pressed down gripping the lifting cable and maintaining the height of the missile. Standing to the side the surveyor’s rod (supplied with every Triax E missile system) is used to verify the height of the missile. Fine height adjust can be made by holding the locking device while loosening the lock screw.

    7.1 Installation The application is provided in the USERDOCS folder located on the Memory Card supplied with the Triax Touch. It is suggested that this folder be copied to the user’s PC, and an archival copy also be created. Install the Triax Touch host application on a Windows compatible platform by running the SETUP.EXE program supplied in the \USERDOCS\HOST folder.
  • Page 24 unknown which drop numbers have been data select all 100 drops. The application will attempt to load all 100 drops but will ignore drops for which there is no data. Before clicking Upload, ensure that the location of the memory card and folder shown in the Memory Card Path box is correct.
  • Page 25 .DRP file so as to prevent confusion for the user during subsequent testing. The .DRP files do not need to be erased as the Triax Touch hand held controller will overwrite old drop test files with new drop test files.
  • Page 26 7.3 Adding individual comments to each drop The report application allows comments to be added for each drop. Typical uses for comments would be to indicate the location on the surface the drop test was made or any observation particular to the specific drop. To add or edit a comment, click once on the desired drop and then hit the ENTER key.
  • Page 27 7.4 Adding a report comment To add or edit a single comment to summarize all the drops within a report, double click on the text box immediately below the menu bar. A text box will appear allowing the adding of a new report comment or editing of an existing report comment.

  • Page 29 NOTE: The HIC Interval is a mathematically sophisticated technical detail regarding how the HIC was calculated for a given drop. Some new standards are using the HIC Interval as an added pass / fail criteria but it has not yet found wide use. Most users will want to leave the HIC Interval setting left to HIDE to prevent confusion.
  • Page 30 7.9 Calculation of Critical Fall Height – EN1177 Method For critical fall height (CFH) calculation using linear regression analysis (i.e. as per EN1177) four drop tests must be performed, changing the drop height to result in increasing HIC values. The drops are uploaded as described in section 7.2, and selected by clicking on each of the four drops while holding the CTRL key.
