When a large domestic port decided to carry out intelligent transformation of 12 stacker reclaimers with an average age of more than 15 years, there was a lot of internal controversy. The opponents made a calculation: the total budget for the transformation is 28 million, while the new equipment purchased is only 120 million, is the transformation worth it? Now, three years later, this remodelling...
