- Abstract
We want to present our attempt using some practical solutions for reabilitation of earthmoving equipments, after long service in ballast stations and which presents many failures. The nature of this failures could be different and we try to classify in three categories, as follows: structural failures which affect strenght capacity of elemments (cracks); mechanical wear failures in joints ( bores, bushes, bolts, etc.); wear and impact failures on buckets. The main percent of reabilitation works, since more than two years, occurred by the WELDCONS SRL specialists are regarding KOMATSU equipments which are using WELDOX 700 - structural steel and HARDOX 400 - wear steel, products of SSAB OXELÖSUND - Sweden. The welding technologies are based on procedure qualification records, tested and verified, using different fillers and welding processes, technologies adapted for a large number of base materials, so for other brands in service in Romania. The reabilitation jobs are carried out more than 90% on site, which reduce costs opposite factory repairing.
