During the slew bearing replacement, before the installation of new bearing, the flatness and surface finishing of bearing seat area is of crucial importance. Poor bearing seat flatness and surface smoothness will have an adverse effect on the bearing life. Achieving flatness within 0.2mm and surface roughness within Ra3.2 is common. But these values depend […]
During the replacement of slew bearing (unloader cranes), below inspections are crucial backlash (usually 0.3 to 0.4mm depending to the manufacturer) and tooth contact pattern/area. Checking contact pattern/area shows how the bearing and pinion are engaging. Fine tuning adjustment is to be made based on the tooth pattern findings.
Relocation of crane and heavy equipment comes with huge technical challenges and risks. Scope includes planning and making procedures for loading/unloading of the equipment onto and off of the vessel, designing the lashing of the equipment to the vessel deck, designing reinforcement structures to the equipment, calculation of the equipment structures for sea accelerations often […]
To improve safety, availability & reliability of port equipment and to improve productivity are of the utmost importance for terminal operators. We assist equipment owners to identify which system shall be upgraded to improve functionality and safety.
It is always good for a maintenance team to get crane functioning systems upgraded from hydraulic to electric. We have a series of experience in converting hydraulic Trim-List-Skew systems to electric.
