PullCalc analisi dell'app per 7 aprile

NEW NOW AVAILABLE FOR CABLE TRAY AS WELL Greenlee continues to drive efficiency with PullCalc, an app that helps electricians and contractors approximate the pull force needed to install an electrical cable inside of conduit or in a cable tray. This will help contractors to select the correct pulling equipment for the jobsite. Data is entered by "legs" and each leg is considered to be a straight run of conduit followed by a bend, except the last leg, which usually has no bend. The calculation for each leg requires the following information to be entered: - Wire size - Number of wires - Conduit I.D. - Duct Material - Material of the Cable Insulation - Coefficent of Friction* - Length of Leg - Bend angle - Vertical Rise The added functionality to calculate force in cable tray allows one to input if the “leg” is horizontal, up or down. This will enable the end user to accurately estimate the complete run of cable tray. *Due to unknown factors involved, it prohibits giving exact results, most notably the coefficient of friction. Lubrication, surface texture, and lay of the cable are never uniform along the length of a conduit run. Comparing the known forces of pulls against the estimated force should give you a guide as for a good coefficient of friction to use for similar future pulls, and a table with some suggested starting points for the coefficient of friction of well-lubricated cable is a drop down option in the app. If lubricant is not used, triple the values in the table. Greenlee continues to drive efficiency by expanding PullCalc app now to use it with the new Greenlee Smart Pull. Now monitor pulling force, speed and distance in real time by connecting with Greenlee smart pull • Yellow flashing alert to end user when you are > 80% of Maximum cable tension • Red flashing alert when you are > 100% of Maximum cable tension • Email data directly from phone • Social media integration
