PHIL has offered a tailgate calculator for years, showing clients and potential clients the type of efficiency they can expect when they add a tailgate to their haul truck. To make the process easier, PHIL has just released a spreadsheet, allowing you to plug in just a little information about your truck fleet and it will give you a conservative estimate on potential efficiencies. Within the document, available on the website, the spreadsheet will go over your current carrying capacity, proposed carrying capacity, fuel consumption, down time, tyre costs and rear end spillage.
