Placart to Protect Details of Heavy-duty Dump Trucks of JSC BELAZ

28 October 2019

The RUSNANO portfolio company JSC Placart won the tender and concluded a contract with JSC BELAZ for the supply of a robotic complex for electric arc metallization. The complex will be used to apply wear-resistant coatings on the gearbox casing parts of dump trucks of JSC BELAZ.

JSC BELAZ dump trucks with loading capacity from 90 to 450 tons are designed for transportation of rock in difficult conditions of deep open pits, at opencast mining of mineral deposits on technological roads in various climatic conditions. To ensure the reliability of dump truck mechanisms under enormous loads, it is necessary to apply modern technologies of hardening and reducing wear and tear of components.

Placart to protect details of heavy-duty dump trucks of JSC BELAZ.

Gearbox casing cuff rings with an outer diameter of up to 1,200 mm and a weight of up to 150 kg are subject to heavy and tear and abrasion due to contact with the sealing rings. Surface hardening of the cuff ring of the motor-in-wheel gearbox casing (material steel 45) is carried out by the method of arc metallization with the Placart material (with wire) of the spring steel base. The coating thickness is at least 0.7 mm (after final machining).

The new robotic complex of electric arc metallization developed by engineers and designers of JSC Placart specially for JSC BELAZ includes a full cycle: operations of surface preparation of parts before and of coating proper.

The unique complex will be used for production of the main serial products of JSC BELAZ. Due to the high and stable quality of coatings applied as well as high productivity, the complex will replace the previously used unit. This will allow JSC BELAZ to significantly increase the productivity of the coating process and increase reliability of the equipment.
