REPAIR OF THE LIEBHERR’s 550 CRANE main TRANSMISSION gear
We have just completed the repeair of the only Liebherr 550 crane in Poland. A complete overhaul of the main transmission gear was required to obtain the TDT certificate. After disassembly and verification of the gears in the workshop, we changed gears, bearings, seals and made adjustments. In addition, we reviewed and replaced the seals of four high-pressure oil pumps. The renovation was carried out for Hes Gdynia Bulk Terminal, Liebherr 550 is the largest mobile crane used by this company and has a lifting capacity of 124 tons.
