At the end of February 2021, a major overhaul of the mining roadheader KSP-42 was completed for PJSC “ShU Pokrovskoye”. All repair documentation for the roadheader was developed by the engineering and technical personnel of MAGMA LLC. On the part of the customer, a number of requirements were imposed on the product for the design of mechanisms and executive bodies, designed to increase the wear-resistant and operational characteristics of the equipment.
The design of the roadheader was subjected to complete defect detection. Some of the assemblies were built from scratch. The repair of the rods of the hydraulic cylinders for lifting and turning the executive body, lifting the feeder, the telescope and lifting the supports was carried out by surfacing with stainless wire.
As part of the technical assignment, the lower branch of the scraper conveyor of the combine was made of wear-resistant material – spring steel, and the upper branch was lined with the specified material.
The warranty period for the operation of the roadheader after repair is 12 months from the date of commissioning or 20 000 m3 of destroyed rock.
