About 

 Currently, open joint Stock Company "Forging Plant of Heavy Stamping" is the main manufacturer of wheel rims for quarry dump trucks with a capacity of 45-220 tons and a supplier to the main conveyor of JSC "BelAZ".

Since 2018, JSC "KZTSH" mastered the technology of manufacturing wheel rims with a key base, obtained by complete machining on CNC machines from a strip thickness of 50mm, as well as the base side and removable landing ring, made of high-precision profile manufactured by Mannstaedt GmbH Germany (Mannstaedt GmbH is a supplier of the above profile for the manufacture of wheel rims by RIMEX), using steel grade D36, which has increased strength, improved weldability (which allows the necessary post-warranty repairs using conventional welding materials at the site of operation) and with a guarantee of resistance to layered breaks.

The use of a high-precision profile in the manufacture of a Bead seat band significantly increases the tightness of the wheel rim during Assembly and increases the life of rim components.

Welding of the base of the wheel rim is performed by electric arc welding under a layer of flux, using the latest ceramic fluxes, which significantly improves the quality of welds and provides one hundred percent weld metal.

Currently, JSC "KZTSH" sets a warranty period of operation of wheel rims 19.50-49/4.0, 24.00-51/5.0 - 200 000 km of mileage or 3 years of operation. For rim 29.00-57/6.0 – 160 000 km.
