REPAIR AND REFURBISHMENT Ӏ SECTOR FOCUS
larger premises at nearby Berg.
“The move means we can handle emergency repair work at short notice,” says Andreas Leicht, manager of the repair centre, “so we can get cranes up and running again quickly.” The space at Ehingen that has been freed up by the move is being used to build up a new spare parts warehouse, which will also speed up services and repairs. “We are still only five
kilometres away from Ehingen so we will be receiving material from there every day; and our experts from the design and production departments can be consulted quickly if we have any questions,” says Leicht. “That creates perfect conditions for us, even if we are facing complex repair work.” General overhaul is the lowest cost option from the Reman programme. The components are removed from the machine, remanufactured to return them to as-new condition and brought up to the latest technical standard where possible, and then returned to the machine. The entire component is covered by the same warranty as a new part. The machine is obviously out of commission at the Liebherr works while the work is done; but by planning ahead, say Liebherr, downtimes can be avoided. Exchanging components –
refurbished for old – is the fastest option; The components are replaced by a remanufactured component with the same warranty as a new part. Service life and performance are identical to those of a new part. In addition, Liebherr will pay a part-exchange fee if you return to them an old part which can be repaired. Repair is the damage- dependent option. After dismantling and inspection, an individual quotation is prepared for repairing the component. The

warranty covers the repair work or the entire component depending on the extent of the repairs and the component. Remanufacturing a component
– that is restoring the defective part to its original condition – offers savings in time and cost, says Liebherr. This is thanks to its standardised processes that give fast turnaround times for component remanufacturing and because the remanufactured part is cheaper than a new replacement. It is also eco- friendly; reusing a part clearly takes fewer of the earth’s resources and emits less carbon than making a new one. Liebherr’s exchange parts, general overhaul or repaired parts offer the same original-manufacturer quality and come with a warranty for long- term use.
ENCORE UNE FOIS Manitowoc offers remanufacturing through its EnCORE programme. It applies to tower cranes as well as to mobiles and includes repair, rebuild, remanufacture, and component exchange elements. On occasion it goes the extra mile for a customers – see box on p19. Rebuilds are by factory-trained technicians to OEM standards. The process can include everything from rebuilding cabs or boom cylinders to updating all systems and renewing electrical harnesses, instruments, drive-lines, hydraulic components and hoses. Remanufactured parts include engines, transmissions, hydraulic cylinders and more; each part comes with a one-year warranty and the crane, says Manitowoc, will be restored to original engineering specifications. For Potain tower cranes
Manitowoc offers three service levels. The ‘Check-up programme’ includes complete inspection of the crane including powered tests;
a detailed report that describes the condition of more than 300 checked components. The ‘Working Condition
programme’ adds mechanisms and safety devices repair, slewing ring bolts check, new hoist and trolley wire ropes, and the crane ready to work on your jobsite with six months warranty on parts and labour. The ‘Premium programme’ includes dismantling and inspection of all components, with shotblasting, zinc primer coat and finish coat, mechanisms and safety devices refurbishment (rather than repair), replacement of all wire ropes, and a new slewing ring and new slewing ring bolts. Manitowoc has EnCORE
Certified Partners located throughout the world and EnORE also offers sales of refurbished used cranes with a stock of 70 or more usually available. Whichever route a crane owner
takes, specialist or manufacturer, the repair and refurbishment of cranes plays a pivotal role in enhancing efficiency, safety, and sustainability. Through this process, outdated and worn- out cranes are transformed into robust, modern machines capable of meeting the demands of today's dynamic work environments. By upgrading key components, implementing advanced technologies, and adhering to rigorous safety standards, companies can maximise their return on investment while minimising environmental impact. Moreover, the refurbishment process contributes to the circular economy by promoting reuse and reducing waste. The refurbishment of cranes
will remain a critical practice for crane businesses seeking to optimise their operations, enhance productivity, and remain competitive in a rapidly changing world.
