![]() ![]() Making a three bucket wide and three bucket wide trapezoid the way I described will e simple to do and be much safer. Having the loader operator count buckets of struck aggregate using a hand held counter is safer for you and everyone else as you have no measuring equipment other than a wheel. but measure it from the ground using an inclinometer please as the pile side walls can not be trusted even when stopped from sliding. If you make the trapezoid three buckets high and three buckets wide the ange of repose will form quickly for you with no issues and it will be easy to measure using the formula for the volume of a trapezoid. The trapezoid will form naturally following the edges of the pile to its angle of repose. Now please follow this excactly: Take the third bucket of material and dump it in the behind the outside piles leaving the hole open between the two outside piles Continue adding material by dumping on the outside edges first following the outer pile line and then dump in the center to fill in the center. You can build a small trapezoid with the loader using this method- Using the struck volume of the loader bucket only Create the base of the trapezoid by dumping the first two buckets of material on the outer edges of the measured width of three buckets widths wide. No you cannot safely create a trapeziod while pushing the material up and over to create the flat top of the trapeziod. I hope yout loader operator is leaving the loader on the ground and not crawling up the pile which will cause a tip over. If the aggregate is the all same size or you have piles of the same size aggregate you can simply make a small trapezoid. volume of a cone: 1/3 *Pi*the radius squared *the height Unless the cone is uniform its useless. Factor= - 0.3819įIRST and foremost you cannot trust any pile at any time!!!!!!!!!!!!!!!!!!!!!! Just walking by it is enought to possibly kill you or someone else. To find volumes and weights of stockpiles with other angles of repose, multiply those values in the table by the factor computed as follows. Weight (tons) = Volume(ft 3) x density (lb/ft 3) x 1 ton/200 lb 1 cubic yard = 27 cubic feet 1 cubic foot = 0.037037 cubic yards CONICAL STOCKPILE VOLUMES (37° Angle of Repose) Volume in cubic feet = 0.2618 x D 2 x h D = Diameter of the base of the cone in feet h = Height of the cone in feet In order to calculate the actual weight of material in the stockpile, determine the density or weight/cubic foot. ![]() Try This he following formula is used to calculate the volume of a stockpile if the diameter and height are known.
