The conditions for the use of truck weighbridges depend on their individual place of installation. Temperature, materials, weight and length of the trucks and especially the frequency of use have an impact on the lifetime of the scale and weighing products.
The “Stevin Rock” quarry in the United Arab Emirate of Fujairah stands for an environment that is an acid test for a truck scale. Temperatures range from 15 to 55 °C during the year, with trucks loaded with up to 110 tonnes of rocks. The frequency of 400 single weighing operations per day, seven days a week, demands the utmost of the installed equipment involved in quarrying and weighing the limestone, gabbro rock, concrete and asphalt aggregates.
Under these conditions, Stevin Rock turned to Danway Emirates, which was able to draw on Minebea Intec as its partner and a manufacturer of premium truck scale components known to offer load cells with a durability above the average. Stevin Rock incorporated the analogue PR 6221 – with the product 15 years on the market now, it has made an important contribution in truck weighing on a worldwide scale and was the tried-and-tested solution providing the relevant appeal for Stevin Rock.
Its easy installation and commissioning, the patented measuring element geometry, maximum IP protection, surge protection, high overload capacity, and of course its precise measurement were other arguments that won the case. In combination with the cable junction box PR 6021 that was installed, it provides excellent lightning protection. The Midrics? MIS 1 scale indicator from durable stainless steel was chosen for its simple installation and operation processes and the high-precision results it yields.
Minebea Intec partner Danway Emirates installed a truck scale at the crusher plant from 2015 to 2017, which runs approximately 140,000 single weighings per year. The scale consists of a platform of 18 x 3 metres equipped with 10 load cells of 30 t, amounting to a capacity of 300 t. The truck scale is calibrated by Danway Emirates every twelve months and its accuracy is just as spot-on as on day one. All results meet the OIML Class III requirements.
