They got their name solely from the place of their operation. They are widely used in industries such as mining (quarrying) of sand, granite, hard rocks, etc. They are in demand in large and small asphalt concrete plants, large logistics centers, where the maximum weight reaches 80 and 100 tons.
This type of scales is made taking into account operation in harsh operating conditions, the weighing platform is reinforced in accordance with the developed technical documentation.
Automobile scales are designed for year-round all-weather operation, without a special canopy over the platform of the scales, with an unlimited number of weighings per day. The offered scales are not wheel-type scales, they are scales of an orthotropic bridge structure, with the width of each half-platform 1100 - 1250 mm, having a technological gap in the middle. The width of the clearance, in contrast to the rutted ones, is 500 - 800 mm (in the rutted ones: 1000-1200 mm). The gap can be closed with technological covers, with secure locks and a convenient removal principle (option). The standard maximum load (Max) of vehicle scales is from 100 to 150 tons (upon request, the Max value can be increased), the scales we offer have a safety margin of 50% of the maximum load. The service life of truck scales is 15 years.
