This semi-trailer is designed to solve the most difficult tasks - when it is necessary to carry as much cargo as possible with the minimum cost of transportation. His place of work may be construction sites of large infrastructure projects, closed areas of industrial enterprises, technological facilities, etc. When developing models of Grunwald heavy tipper semi-trailers, the starting point was the idea of high working efficiency even in the most severe operating conditions. Their high reliability, increased uptime, enhanced design skillfully combined with modern technical solutions and advanced components.

Grunwald heavy tipper semitrailers have repeatedly proven their high efficiency in the most difficult operating conditions. The prerequisites for this success were the high competence of Grunwald engineers in creating dumping equipment, the possession of unique experience and knowledge. Over the past years, the experience of operating Grunwald semi-trailers in a wide variety of weather, climate and road conditions has been consistently studied. Studied and analyzed data on the loads that the equipment experiences under different operating conditions and conditions. This gave an understanding of the best combination of technical solutions, techniques and materials needed to perform the most difficult transport tasks.
The reinforced frame of the semitrailers contains a substantial margin of safety, which allows you to confidently operate with the maximum load of the body. The side member shelves are made of a single hot-rolled strip and are welded from two sides during assembly, which guarantees high structural strength. The body has a longitudinal stiffener, which increases the rigidity of the structure. An important difference between heavy models is the gable tire. This allows you to increase the reliability of operation of rubber, to unify its dimension with rubber tractor. The heavy-duty semitrailers are designed for operation with tractor units with a fifth wheel height of 1350 mm.
The steel tipper body is manufactured using the Half-Pipe technology, and is characterized by great durability and safety in operation. The walls and bottom are made of steel S 355 MC, the thickness of the walls is 6 mm, the bottom is 8 mm. The body is assembled from three parts of lap welded to a value of 100 mm, which avoids the abrasion of welds with an abrasive load. Tilted at an angle of 15 degrees, the rear wall of the body is mounted in its upper part on bearings and locked from the bottom with automatic locks. The hydraulic equipment of the semi-trailer consists of a hydraulic cylinder manufactured by HYVA or Binotto.
PAINTING FOR SEVERE CONDITIONS
The paint quality of Grunwald semitrailers meets the requirements of the ISO standard for severe climatic conditions. The key to long-term protection of the product from corrosion is the appropriate preparation of surfaces before painting. Therefore, a fully assembled metal structure is subjected to thorough bead-blasting.
Painting is carried out according to modern technologies with paints and varnishes on an epoxy and polyurethane basis. All the materials used are of European manufacture and of extremely high quality, which makes it possible to successfully operate the semi-trailer in harsh climatic conditions. When painting by the quality control service, phased control is carried out at all technological stages of the process.
Four BPW axles are installed as standard, with a payload capacity of 9,000 kg each, with air suspension. Used axles in the performance of Heavy Duty, reinforced in accordance with Russian road and climatic conditions. Drum type brakes. Pneumatic system from the world leader - WABCO concern. Also available on request with disc brakes and an axial unit of three axes SAF Custom Design.
All mounted components - axles, pneumatic system, electrics, support devices and fittings are purchased directly from leading European manufacturers. This approach provides reliability in operation and simplifies maintenance of equipment due to a larger number of service stations and greater availability of spare parts.
- Front / rear lifting axle. In some cases, it reduces rubber wear.
- 3,5" King Pin
Grunwald semitrailers are certified by the State Standard of the Russian Federation in accordance with the latest UNECE regulations.
The warranty period for the semi-trailer is 12 months from the date of sale. Axial unit warranty as standard - 3 years with no mileage limit.
