THREE NEW TADANo RouGH TERRAINS FoR IRAqI oIL CoMpANY


Baji, Iraq-based North Refineries Company (NRC) – one of the Iraqi ministry of oil companies, reports that recent relative peace in the country over the last few years has enabled it to produce around currently 310,000 barrels of refined oil per day. To help facilitate this, the company has an equipment portfolio comprising over 100 heavy machines including trucks, heavy machinery, forklifts, and cranes. The company has now added to


its crane fleet three new GR-300EX rough terrain cranes from Japanese manufacturer Tadano. Sudad Ibrahim Majeed, senior chief


engineer at North Refineries Company, credits ongoing satisfaction with Tadano’s quality, plus ongoing service, as key factors in the decision to purchase the new GR-300EX-3 models.


When deciding which new machines to include in their operations he said his priorities included "safety, options, good prices, and delivery”. Majeed also cited the crane’s “good design and new technology”, aiding manoeuvrability inside sites, as being a factor. The new GR-300EX models are being


used for a variety of general maintenance activities involving: welding; lifting pipes; lifting damaged equipment; and handling


and lifting tanks, heat exchangers, and valves.


The cranes were purchased from


Tadano via agent Sardar Automobile and Machinery Trading Co. (SAM). Read more about the Middle East in our feature starting page 18.


CRAWLER uSED IN poWERpLANT CAvERN


The new Tauernmoos pumped storage powerplant, owned by railway operator ÖBB-Infrastruktur – which gets all the electricity for its trains and stations


from renewable energy sources, is being built by Central and Eastern European construction group Swietelsky deep inside the mountains in Upper Pinzgau, near Uttendorf, Salzburg, Austria. The infrastructure of the underground


hydro powerplant is being built inside a cavern which extends over a length of 73 metres, a width of 25 metres, and a height of 40 metres. To build the powerplant 15,000 m3 of


structural concrete and 2,000 tonnes of reinforcing steel, along with formwork panels and machines, must be lifted and installed within a confined space within the cavern and on a tight schedule. There is not much space for parking machines and moving them is difficult. The lifting solution Swietelsky is using is a Palfinger PCC 57.002 crawler crane. The crane was selected due to its compact size (5.8 by 1.9 metres), lifting capacity of 450kg, and working radius of almost 30 metres (or 3,700kg at a height of 18 metres and radius of eight metres. The crane is working on various levels within the cavern. This is aided by the crane’s ability to separate from the

crawler module and be transported to the next level in two parts.


The crane can operate using either diesel


or electric drive but inside the cavern it is using electric power for CO2 neutral operation, ensuring that the workers are not exposed to exhaust fumes. They also benefit from reduced noise and vibrations. According to Palfinger the crane is also


well suited to the site due to its unique shifting function and 360° geometry monitoring which can increase lifting force and reach. The crane’s software calculates all centres of gravity to provide optimum stability.


The crane is being used with an


articulated knuckle boom (14°) and fly jib (25°) in order to be closer to the loads whilst also avoiding objects and protruding edges. “Thanks to the PCC’s shifting function in combination with its long reach, we can transport even the heaviest loads to distant locations in the cavern,” said crane operator Wilfried Pirker. “This makes our work a lot easier.” Read more about the use of knuckle boom cranes in our feature starting page 36.
