KNUCKLE BOOMS Ӏ WIDER PERSPECTIVE
metres with the base crane and 2.3 tonnes at 46.10 metres with the fly-jib.
The close-range performance is helped by the fact that the base boom is telescopic, extendable to double its closed length. It is, as you would expect, large – in fact huge – and is actually a twin boom, made up of two units side by side, connected at each end; four hydraulic cylinders actuate it. It is also telescopic – extendable by double its closed length. The telescoping helps increase the close-range performance and means that the crane can be compact if necessary but can give more tipping height for the main boom when that is required. Truck-mounted, offered on an eight-axle Scania, it, of course, needs outriggers and
counterweights to lift the massive loads it is designed for. The turret of the crane holds eight tonnes of ballast on arms that can be extended rearwards to increase the counterbalancing moment. U-shaped ballast units can be hooked over the outriggers as well. The crane has negative boom articulation for operating in low or ultra-confined spaces, Sirlock 3 intelligent control system for real- time load monitoring, and TES 4.0 active stability monitoring designed to enhance safety on any terrain. Suggested applications include what Copma describes as ‘infrastructure mega-lifts’ and also heavy industrial repair. These tasks could include relocating presses and production lines or lifting generators and compressors during retrofits. It can do such
tasks with negative boom articulation through low entryways or under mezzanines or elevated gantries; equally it can lift factory equipment over roofs and lower it through narrow floor gaps. It is a huge and very versatile machine; and it is an awful long way from a loader crane. From fish farming to subsea lifting to heavy construction and industrial repair, knuckle boom cranes have proven themselves to be far more than just truck-mounted loaders. Their adaptability, scalability and technical evolution make them indispensable across industries both on land and sea. Whether compact or colossal, mounted on trucks, crawlers or boats, the knuckle boom continues to push boundaries – demonstrating that its story is still very much unfolding.
THE ART OF LIFTING: FOSSEWAY HIRE INSTALLS SCULPTURE WITH FASSI CRANE
UK lifting, transportation, haulage and storage specialist Fosseway Hire was commissioned to transport and lift a series of valuable sculptures into place at Compton Verney art gallery in Warwickshire. To lift the sculptures Fosseway used its Fassi F485A2.25 xe- dynamic crane with Scanreco remote control. The crane is part of
Fassi’s heavy-duty range and is in the 48tm class. Originally made for and installed on the facade of the Metropolitan
Museum of Art in New York, USA, in 2022-23, ‘Gilt’ by internationally acclaimed artist Hew Locke has now been installed on Compton Verney portico where it will be on display for the next two years.
