You will want to measure multiple loads and stockpiles to calculate compaction changes as more material is added to the stockpile. (You will use this number as your conversion factor for tons per cubic yard.) The number you reach in Step 5 is your aggregates stockpile density at a given point in time. Use an iPhone app or drone to determine the sample pile’s cubic yards.ĭivide the tonnage (weight of the three samples) by the cubic yards (volume). Place the three loads in a “conical-shaped” pile away from any other material. While most OEMs offer such weighing options with loaders these days, aftermarket options are available such as those offered by MOBA Corp., Peachtree City, Georgia. Write down the weight of the three sample loads combined. If you have an older model machine with no scale, you can place all three loader bucket loads in a haul truck whose current tare weight you know, and then weigh it at a truck scale when loaded. With this “smart machine” technology, which is now standard on Cat wheel loaders, data is displayed in real time on a screen in the operator’s cab for the purpose of improving your productivity and loading accuracy, but you can, of course, use this technology when calculating your stockpile densities. For example, Cat Payload with Assist from Caterpillar is designed to provide accurate weighing of bucket payloads as you work. Weigh each bucket load with the wheel loader’s onboard loader scales. Have the wheel loader approach the stockpile at a 90-degree angle to the right of the stacker for the third sample.Have the wheel loader approach the stockpile at a 90-degree angle to the left of the stacker for the second sample.Have the wheel loader approach the stockpile in line with the stacker to take the first sample.

Take three samples of material with the full capacity of the wheel loader bucket. ⑧ Construction Phases– At the bottom of the screen, the first tab shows the existing ground subsequent tabs show phases of proposed earthworks.For a stockpile that is 50 cubic yards or greater: ⑦ The Colour Keys – These colour keys show the shading which is used to display the existing and proposed topography. A more detailed analysis can be produced in a report or spreadsheet. ⑥ The Results Panel – The results panel shows an overview (cut, fill, net) of the earthworks estimation for the current phase. ⑤ Navigation Panel – The controls in this panel can be used for zooming, panning and rotating (in 3D) the views. camera controls, lighting and grid lines. ④ Display Panel – This panel is used for changing various display options, e.g. ③ Earthworks Panel– This panel is used for adding, removing and editing the earthworks elements, which are combined together to create a proposed surface. ② Measurements Panel – This panel is used for adding, removing and editing the measurement elements, e.g. ① Design Area – This is the main display, where the existing ground and the proposed earthworks will be displayed. The different elements of the Kubla Cubed (above) user interface are briefly described below: Below we look at one approach using Kubla Cubed.

However, these days it is much faster to use software for this task. It is possible to calculate the stockpile volume using graph paper and plotting the points. You can complete your survey using ground based surveying equipment, although it’s now becoming more common to use drones (UAV’s). If approximating to a simple geometric shape is not considered satisfactory, then an alternative approach is to complete a survey of the pile. However, to calculate a more accurate total volume, you will need to complete a survey of your stockpile. The above tools are useful when the stockpile is a standard geometric form. Here are a couple of examples of online calculators, which (with your data) can be used to calculate the volume and mass of both coned and rectangular stockpiles. You can either do this task the old fashioned way with a calculator, or use spreadsheets, or some online tools. When we approximate the stockpile to that shape, we can use some basic measurements from the stockpile (height, diameter of base etc.) and a known mathematical formula to calculate the volume. After you’ve done that, it is a good idea to start with some more technical approaches.ĭue to the way that they are constructed, stockpiles often conform to a standard shape.

The cheapest and quickest way is to find someone with experience to eyeball the pile and ‘hazard a guess’. There are many different ways to calculate a stockpile.
