Multipurpose Sea Cargo Complex Bronka, the newly built port located near Lomonosov in Russia, has ordered a second unit of Liebherr’s biggest ever mobile harbour crane, the LHM 800, which has an under-hook lift capacity in two-winch/four-rope configuration of 308t.
Bronka was the customer for the first ever LHM 800, built in Rostock and delivered fully assembled in September 2015, while the second and third LHM 800s were delivered to Montecon in Montevideo in July this year. Bronka’s second LHM 800 – the fourth unit built by Liebherr – is currently undergoing final assembly at the company’s Rostock plant.
During a visit by WorldCargo News to Liebherr Rostock last month, the crane maker performed the ‘marriage’ of the latest LHM 800’s slewing platform and its undercarriage. Weighing 80t, the slewing platform was slowly lowered by the factory hall’s overhead crane onto the crane’s undercarriage, which weighs in at 220t. One of the numerous connecting bolts protruding from below the slewing ring is a longer ‘lead bolt’, allowing the platform to be correctly positioned, after which a certain number of the bolts were initially tightened so the platform couldn’t tilt on the undercarriage, before all the bolts were firmly secured.
This ‘marriage’ was one of the crucial steps in the assembly process, after which electrical connections could be made and the crane filled with diesel fuel and hydraulic fluid. Because the engine is situated above the slewing platform, the marriage of the two parts means that the crane could then be self-driven out of the production hall for the tower to be installed and final assembly to take place outside.
Elsewhere in St Petersburg, two electric-driven LHM 500s have just been delivered from Rostock to Container Terminal St Petersburg, along with an electric LHM 500 to Helsingborg in Sweden.
