Portable Truck Scales are designed and manufactured for installation on a prepared site (aircraft or road slabs on a sand and gravel bed). This design of the scales is installed without additional construction of the foundation for the scales, and in case of transfer to another place, the entire cycle, including the installation of the scales, takes about 4 hours. The people often use the term "portable auto scales".
Truck Scales are designed for weighing trucks and cars, taking into account operation in street conditions, including at subzero air temperatures and exposure to atmospheric precipitation. The places where the load cells of the weighing system are installed are protected from dust and dirt, the load cells themselves have a degree of protection of at least IP67. The load-bearing metal structure of the weighing platform is designed and manufactured taking into account the increased loads according to the orthotropic bridge scheme.
The offered scales are not wheel-type scales, they are scales "inside" of which there is a bent U-shaped profile that increases the safety margin of the equipment and creates a number of main stiffeners. Automobile scales consist of pairs of semi-platforms, the width of each is 1100 - 1250 mm, and between each other they have a technological clearance of 500 - 800 mm (as a rule, in wheel weights it is 1000-1200 mm). The gap in the scales, if necessary, can be closed with technological covers with reliable locks and a convenient removal principle, which provides quick access to the sub-platform space for high-quality maintenance of the weighing platform.
