Sarens recently completed the installation of two new bridges across the Kieldrecht Lock (Belgium). This lock, also called the Deurganckdok lock, is the largest in the world since its opening in 2016, and allows access to the Port of Antwerp. In order to transport and install the two elements Sarens used the barge “Caroline”. Thanks to this method, the lock was blocked only a minimum of time. Each of the two bridges measured 100m long by 15m wide and weighed 1600t. Dimensions that limited the working space on the barge. However, it took several manoeuvres to rotate the two bridges while they were on the barge. Finally, the strict tidal restriction for one bridge was also a crucial factor. The Sarens team used its CS1000 jacking system, steelworks, and SPMTs as well as the barge and various related marine equipment. Thanks to the careful planning and execution of the different stages, Sarens was able to successfully transport and position the bridges across the Kieldrecht Lock on time.
To be able to assemble the retractable roof of the Al Bayt football stadium in Quatar, Sarens, on behalf of the Italian construction company CIMOLAI, performed the lifting of this various elements using two crawler cranes.
The two machines were a Demag CC6800 crawler crane rigged in SWSL 78/84 configuration with 450t of superlift and 96m radius with a total load of 95t. The second cane was a Liebherr LR1750 rigged in SWSL 84/91 with 400t of superlift and 102m radius. Its total load was 29t.
This tandem lift had to be planned down to the smallest detail to take into account the pick-up position and travelling distance the cranes had to cover before drop-off. While the customer had planned to use three cranes to perform the lift, only two cranes were needed for the operation. It took Sarens two months to complete all the work on this site.
Sarens has just installed two steel supports for drilling shaft machines in Luban, Belarus. These two structures, designed to be as heavy as possible, consisted of 10 modules weighing between 40 and 178 t each. It took two months to carry out this operation undertaken on behalf of client JSC Promtechmontazh. Sarens used a Demag TC2800-1 truck crane, whose configuration had to be changed 3 times on this site, as well as a Grove GMK all-terrain crane delivered with 25 different trailers from the town of Grodno located 350 km away.
“The Sarens team successfully completed the installation according to our wishes. We hope for further productive cooperation,” said Vladimir Matrenkin, director of the JSC Promtechmontazh Soligorsk department.
In the British port of Whitby, the Sarens crew was asked to for launch the new Guiding Light trawler. This 26m long, 8m wide and 12m high boat weighing more than 250t required the use of a Demag TC2800-1 lattice boom mobile crane.
Indeed, the narrow limits of the site required the use of a powerful machine, stable and with a small footprint. The TC2800-1 was equipped with a 42 m main boom, a 30 m superlift back mast and a 200 t superlift counterweight.
Once the official launch ceremony was completed, the TC2800-1 lifted the entire mass of the trawler with its 200T superlift counterweight. The load was then slowly and precisely slewed anti-clockwise until it was directly above the water. The trawler was slowly lowered into the water, releasing the weight from the crane and completing a safe and successful lift.
The Sarens Group has just announced the opening of a new branch depot in Mozambique near the city of Palma in the far north-east of the country. This new location is a part of the group’s strategy to ensure a permanent presence in the country with a view to the future LNG project in Mozambique in 2019. Sarens has already brought its 120T and 60T rough terrain, 100T all-terrain, and truck and trailer equipment to the site. Construction of the new 5,600 square meter depot is about to begin and will include accommodation, training facilities, office and workshop containers, workshop facilities, washing bay, laydown area, parking area ….
In addition, Sarens has made the choice to invest in the training of the local population. Thus, the group has already trained and certified three crane operators.
At the port of Ghent, in Belgium, Sarens has recently presented its new crane SGC-250 with impressive capacities. Being one of the biggest and mightiest cranes in its range, it has a maximum load moment of 250 000 metric tonnes, allowing to lift until 5000t. Even with a radius of 100m, the SGC-250 can lift until 2000t. Its main boom length can be extended from 118 to 160m, and its jib can reach 100m. In total, this combination provides an incredible height of 250m, with a 275m radius ! The crane will be used in 2019 during four years to build the nuclear plant of Hinkey Point C in England.
This outstanding order consists of 68 THP/SL and 24 PST/SL axle lines as well as four 280 PS PowerPacks. It is destined for one of the largest oil projects in the world, in Kazakhstan. Sarens is responsible for the entire logistics from 2017 until 2020 for over € 450 million, the largest contract in the history of the Belgian group.
With a modular design, the THP/SL modules can be configured in all required combinations, while the variable wheelbases and a wide range of accessories enable them to handle loads of varying shapes and sizes. They are also distinguished by their robustness. The PST/SL modules have a tractive force of 160 kN per axle line and are particularly suitable for use in combination with the THP/SL.
The four PowerPacks from Goldhofer provide the necessary propulsion for particularly bulky and heavy plant components.
“Goldhofer was the only heavy-duty module manufacturer who could guarantee punctual delivery of high-grade axle lines in a such a quantity within such a short time. As a result we were able to meet our contractual obligations towards our client, and Goldhofer was able to consolidate its position as a long-serving transport technology partner of the Sarens Group,” said Jan Sarens, Equipment Trade Officer of the Sarens Group.
This order increases the size of its Goldhofer fleet to a total of more than 300 axle lines.
Sarens has mobilised 17 cranes to help building the Al Bayt Stadium, one of the eight stadiums of the 2022 FIFA World Cup, hosted in Qatar from November 21 to December 18, 2022. This operation was made possible by Sarens’ crane rental division represented by Qatar Al-Attiyah International Group, which has been working closely with Qatar’s Supreme Committee for Delivery & Legacy on the construction of Qatar’s eight major World Cup stadiums. In collaboration with the Salini Impregilo Group and Galfar and Cimolai joint venture (GSIC JV), along with Cimolai S.p.A., Sarens has provided cranes for the construction of the Stadium in the City of Al Khor.
A total of 17 mobile and crawler cranes are deployed on-site over a period of 18 months, including a Demag CC 6800, Liebherr LR 1750, Liebherr LR 1400, Liebherr LR 1300, Liebherr LR 1280, Liebherr LR 1250, Liebherr LR 1200, Liebherr LR 1160, Liebherr LR 1130, Liebherr LR 1100, Liebherr LTM 1500, Liebherr LTM 1350, Liebherr LTM 1250, Liebherr LTM 1160, Liebherr LTM 1070, Kobelco CKE 1350 and a Tadano GR 800 EX.
The stadium’s design is inspired by traditional Bedouin tents. Once completed, the stadium will host 60,000 football fans in an area of 200.000 square meters. The preparations for the 2022 World Cup also include construction on the Doha Metro System, new orbital highways and expressways.
Sarens has mobilized a 10-member crew and two crawler cranes to perform a series of forty lifts at the Bellara gas power plant in Jijel, Algeria on behalf of its client Hyundai Engineering.
At the beginning of the mission, Sarens used a modular trailer to transport modules from storage to the lift area. Today, the crew is on its way to completing the full series of lifts, which include 118t-203t power plant modules lifted at 22.5-30 m. The equipment for this operation, that took three days to set up, includes CC2800-1 crawler crane (600t) in SSL configuration and with 84-metre main boom, CC2400-1 crawler crane (400t) in SH configuration and with 42-metre main boom, K25 modular trailer with 12 axles and one mobile crane. One of the main challenges for the Sarens crew was the new procedure the client was using to detach modules from the stand-up jig, which creates a mere 6mm distance between the module and casing. “This method consists of extracting the module with one crane only, by fixing the ‘stand-up jig’ to the metal structure of the casing during the lift,” explained the engineering manager Yassine Amrouche. To do it, the team first performed a tandem lift, and then made a rotation up to a point where they can detach the module from the frame, rotate it again and put it into its final position. The Sarens crew has completed twenty lifts and now is preparing for the next 20 modules to be installed soon.
Bellara is a 1.400MW gas powered plant and a key part of the larger Algerian and Qatari Bellara steel complex project. Algeria’s Sonelgaz has began the construction of this $800 million-dollar facility in 2013 and it should be fully operational by the end of this year.
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.
