The Sarens company recently assisted the roof extension of the Anoeta football stadium in San Sebastian, Spain, for the joint venture client Anoeta Envolvente, composed of Altuna y Uria and Construcciones Moyua. For Sarens, the task consisted in performing tandem lifts of four new steel truss girders of 400t and 156m long. The company also lifted four smaller trusses. For these several operations, two Demag Superlift 3800 lattice boom crawler cranes in SWSL configuration has been used, which could bear 201t with a maximum radius of 54m.
“The crane’s main parts were transported by sea vessel and delivered to a harbour near the work site. Then, up to 100 trucks delivered the equipment to the stadium, located in the middle of the city,” as stated the Belgian firm. On site, ten days were required to install and rig each cranes, working mainly by night in order to not disturb other subcontractors and local city transport. Four crew members worked together for each operation for the tandem lifting of the steel girders.
McGovern Crane Hire, located in Derbyshire in central England, has successfully raised a 21-tonne generator on the grounds of the Birmingham Children’s Hospital. This lifting presented a major challenge. The team could have used a large crane with a minimum lifting capacity of 350 to 500 tonnes but the extremely tight space conditions, an aisle of the hospital, made impossible the use of a crane with sufficient performance for a lifting of this weight. The solution found by the Mc Govern teams was using a Demag AC 220-5 all-terrain crane that was compact enough to fit in the driveway, yet with the innovative IC-1Plus control system, it offered sufficient lifting power with asymmetrically configured outriggers.
In order to lift the load with its weight of 22 tonnes, including hook block and lifting tackle, the AC 220-5 was equipped with a counterweight of 51 tonnes. The outriggers were set to meet the needs of the job site. Thus, it was possible to lift the generator at a boom length of 33.3 meters and a radius of 15.0 meters off the lowbed trailer in the driveway to a height of 10.0 meters. It was then lifted over adjacent buildings by slewing the crane directly over the front right rigger which was fully retracted, the crane continued slewing right on the right until over the back right rigger which was extended to three quarters and easily lowered down at the desired location with a final radius of 19.7 meters.
“Thanks to the IC-1 Plus, however we were able to configure the crane to carry out the lift utilizing only 84% of the rated lifting capacity while using reduced counterweight, ”
ALE has recently completed the lifting and load-our of four suction anchors for the Zohr gas project, located in the Egyptian sector of the Mediterranean Sea.
The various manoeuvres took place in the Port of Alexandria where the four suction anchors were stored near the dock. Each of the columns had different weights and dimensions, ranging from 185t to 220t. The anchor parts were moved using a crawler crane with 850t capacity and a radius of up to 30m. In addition to these pieces, ALE has loaded-out other less imposing pieces such as a 65t circular hub and a 95t rectangular ladder piece. The ALE team completed the installation of all parts safely and within the deadline set by the client.
Ale recently lifted two 400t and 120m long steel wishbones, which form the central arch of the Matagarup Bridge in Perth, Australia. To do this, the British company used barges on the Swan River to float the structures to the piers and then used the Mega Jack to lift them. The first one was completed on 27th April and the second one on 12th May. The new bridge, reaching 72m above water level, will connect eastern side of Perth city with the Burswood Peninsula, where a new 60 000 seat stadium was recently opened.
Sarens, the Belgian heavy lifting specialist, has transported a 580t pile template in Wallsend, Newcastle Upon Tyne, United Kingdom. The work was done on behalf of a client Van Oord, who is responsible for installing 102 three-legged jacked foundations for the Scottish Power Renewables (part of the Ibedrola Group), which is building the East Anglia ONE offshore wind farm in the North Sea. The project equipment included 3×6 axle lines of self-propelled modular transporter, a 400t and a 220t mobile crane and 21m bridge beams (converted to link spans). Most equipment arrived from the UK, while the link spans were delivered from the Netherlands to the UK via the client’s barge. It took one day to set up all of the equipment and prepare it for the operation.
The Liebherr crawler crane LR 10000 operated by the abnormal transport company Emil Egger AG, settled a silo of 470 cubic meters capacity in Oberiet, a Swiss municipality next to the Austrian border. The construction site had some space constraints, preventing to use the jib extension.
« The benefit of our solution was that using the LR 11000 for this job meant that a derrick jib was not required as would have been the case if a 500 tonne crawler crane had been used. That would have presented a massive problem as a result of the extremely constricted space available », explained Michael Egger, Director of Emil Egger AG.
The Ale company recently loaded-out and installed the « Brug van den Azijn » bridge over the Albert channel of Antwerp in Belgium. Measuring 124m long and weighing 1200t, it had been in first place transported by barge from Wondelgem to Antwerp. Then, the structure had been loaded-in on a site near the final location, where the bridge’s arches were assembled. The full bridge has been lifted by the Mega Jack 800 at 8m high to position it higher than the abutments, and then by 3m for its final position. Tom Van De Locht, Project Engineer, stated the Mega Jack 800 was essential for the smooth operation because thanks to this system « the operational time was reduced, and it was easily integrated on site because of its small footprint and compatibility with our other services ».
On March 6, 2018, the third Summit organized by ESTA (European association for abnormal transport and mobile crane industry) and FEM (European materials handling federation) will take place in the Bucerius Law School of Hamburg. Gathering most of the major actors of the Industry, it will deal with safety and standards in on-shore wind farm construction. The themes covered will be risk management, crane design, on-site delivery and transportation standards, accident analyses, productivity and supply chain relationships.

Aertssen group, based in Stabroek in Belgium, has shown its willingness to take over the activities and the staff from the crane rental company Michielsens. This acquisition is part of the group growth strategy which is to maximise the strengths of both companies. In this way the group wishes to strengthen its own position in the market, as a heavy transport operator offering complete solutions and as a crane rental company for all the customer segments. « The acquisition of Michielsens is an important strategic step and underscores the healthy ambitions of our family business for growth, both in Belgium and internationally », declared Greg Aertssen, Chief Executive Officer of the company. « The idea is for Michielsens to be run as an independent business unit within Aertssen Group with retention of the current employees and its own identity and customers, which very much complement those of Aertssen ». As the firm says, « the takeover is expected to be in place by mid-February 2018, once the standard legal procedure has been completed ».
Three Linden Comansa tower cranes are currently operating on the site of the future Ituango hydroelectric power station.
This plant will be intended, once commissioned in late 2018, to be the largest power plant in Colombia. It will generate up to 2400 megawatts of clean energy, nearly twice that of the San Carlos, currently Colombia’s largest power plant with a generating capacity of 1240 megawatts.
To carry out the construction of the power plant, no fewer than 3 Linden Comansa tower cranes are mobilised.
The first two, a 21LC450 with a height under hook of 54,6m and a maximum load capacity of 20 tonnes and a 16LC185 with a height under hook of 59.5m that can handle a load of up to 8 tonnes, have been assembled on a folding cross base with travelling system so they can be moved on tracks installed on the ground. This configuration allows them to cover a larger surface area faster.
The third crane, an 11LC160 with a height under hook of 40 metres and a maximum load capacity of 8 tonnes, has been in three different locations but still very close to the other two cranes. It was installed in an area higher than the spillway in order to be used to help build the tunnel which will provide road access to the spillway. Once this initial work was completed, the crane was mowed to a slightly lower area for the construction of two intake tunnels, which will take water from the reservoir to the machine room and turnines.
