![]() Volume scanning technology brings accuracy to truck measures For example, pushing the bucket hard into the bottom of the stockpile produces a more compacted load than loosely scooping off the side of the stockpile.ĭue to the self-compaction/settlement of heaped material under its own weight, multiple bucket loads may not equate exactly to resultant cumulative heaped volumes in truck bins or in stockpiles generated from truck loads. How the bucket is pushed into the stock-pile significantly impacts the effective volume when transferred to truck bin. It’s also difficult to load into the bin corners. Loader/excavator operators often cannot even see inside the truck bins. In practice trucks and trailers are not loaded exactly to capacity every time. The same is true for trucks and trailers. And it’s definitely not practical to get out and level every bucketful! In fact the loader operator can’t generally see the scoop very well. In practice operators do not load each bucket consistently to the same level. Even in a single stockpile, the density of material scooped lightly off the top can be quite different from material dug deep from the bottom of the heap. Material density and moisture content can vary considerably across a quarry site and with depth. Conversion factors are genericĬonversion factors are typically computed on a dry day in carefully controlled conditions and do not necessarily reflect the weight-to-volume ratio of supplied materials. Often the differences between what the supplier claims was in a truck (in cubic metres or cubic yards) and what the buyer claims, is quite significant. The volume of a load changes due to the product bedding down as a result of vibration, braking and bumps during transport. If the material is wet when loaded, it can weigh considerably more at the point of loading than at the point of unloading as water run-off occurs in-transit. This practise, which often occurs in quarries, works in the supplier’s favour. Wet is heavier than dry.Ī stockpile can become wet because of rain, or from deliberate wetting of stockpiles to prevent dust. Weight varies depending on the moisture content of the load material. Here are a few of the key issues with traditional truck measures. Why traditional truck measures are inaccurate Unload truck/trucks into hole or container of known capacity.Count scoops using a loader bucket of known capacity.Weigh using an inline weighing system on loader bucket and convert to volume.Weigh using a weighbridge and convert to volume.There are 6 basic methods generally used to determine truck measure, either as the sender or receiver of the load. So what are the traditional truck load measurement methods and what exactly are the accuracy issues? Traditional truck measures The trouble is, with traditional load measurement techniques, there is too much ‘guesswork’ involved due to the use of inaccurate measures and conversion factors. This is an age old problem in industries where flowable solids are carted and traded by the truck-load such as civil construction, quarry and landscape supply. Loadscan® OverView Load Management Softwareįind yourself arguing with a customer or supplier about the exact measure of material being bought, sold or transported?.This spirit has made us the foremost producer of quality aggregate material in the Ohio River Valley, and helps us take care of our most important asset, the customer. Driven to be the Best Mulzer management and employees share a spirit of integrity, dedication and drive to be the best. The Mulzer family has been delivering ever since. To help fulfill that need, the Mulzers opened their first limestone quarry at Eckerty, Indiana, and delivered on their first contract…1,500 tons. In 1946, the Mulzer brothers saw the need for a close supply of construction aggregates during the post World War II construction boom. began building culverts for highway construction. It started in 1935 when Roland, Edgar and Arnold Mulzer, Sr. Whatever the project requires, Mulzer can supply it! A Family Business Since 1935 The story of Mulzer Crushed Stone is very much the story of success. We have worked with many companies and governmental agencies on custom products. We also produce derrick stone, rip-rap, sand, gravel and high calcium limestone for power plant desulfurization equipment. About Us What We Do Day after day, Mulzer delivers thousands of tons of state-approved crushed stone for “driveways to highways” construction projects throughout our market area.
