Best practice A truck weighbridge solid as rock – thanks to load cells by Minebea Intec One of the most demanding applications for weighing is the measurement of loaded and unloaded trucks, particularly in extreme environments exposed to a high range of temperatures, as is the case in United Arab Emirate. Key facts Stevin Rock is the leading quarrying operator in the Middle East, focusing on limestone, gabbro rock, concrete and asphalt aggregates from three quarries, supporting mainly the construction and real-estate sector in the region. At Stevin Rock’s quarry in Fujairah, trucks are loaded with 110 tonnes of rocks in 400 single weighing operations per day. To meet Stevin Rock’s requirements, Danway Emirates installed a truck scale with Minebea Intec’s load cells PR 6221 and the weight indicator Midrics® MIS 1 at the plant in 2015. T he analogue load cell PR 6221 guarantees precise measurement results from 12.5 to 75 t, a long product lifetime and exceptional reliability, also in the emirate of Fujairah’s extreme environment T he simple operability and high accuracy that the Midrics® indicator offers save time and money in the long run Truck scale load cell PR 6221 Cable junction box PR 6021 Indicator Midrics® MIS 1 Customer Stevin Rock was founded in 1975 as a 100% owned subsidiary of the Dutch civil engineering company Volker Stevin. Over the years, it has focused more and more on producing large-sized rocks typically used in breakwater application. In 2007 it merged with Ras Al Khaimah Rock Company (RAK Rock), becoming one of the largest quarrying companies in the world.

Project goal and implementation 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. important contribution in truck weighing on a worldwide scale and was the tried-and-tested solution providing the relevant appeal for Stevin Rock. Highly durable truck scales are required for the extreme conditions at the United Arab Emirate of Fujairah The truck scale load cell PR 6221 guarantees precise measurement...
