Two 150 EC-B 8, a 220 EC-B 10 and two 250 EC-B 12 were used for this project. The flat-top cranes had jibs measuring 40, 45 or 55 metres in length and their hook heights ranged from 40 to 73 metres. Using this setup allowed the tower cranes to work smoothly in very tight conditions and to optimally cover all parts of the construction site. The flat-top cranes moved a wide range of building materials, including formwork elements, steel reinforcements, concrete buckets, and windows.
Slimline tower systems for small gaps on site
To make operations as space-saving as possible, all top-slewing cranes were mounted on foundation anchors. 16 HC 175, 21 HC 290 and 24 HC 630 tower systems were also used, depending on the size of the crane. With slimline corner post dimensions of 1.6 x 1.6 metres, 2.1 x 2.1 metres an 2,44 x 2,44 metres respectively, the tower sections fitted snugly into small gaps between buildings. The cranes were erected in June 2022 and dismantled in spring 2023.
During this time, the EC-B cranes were involved in completing the second and third construction phases of the "Elite Park" development, comprising 464 apartments. The number of floors rose quickly: Bayer Construct opted for modern equipment so that the construction of a storey took only two weeks. The ten-storey buildings, each with residential accommodation of varying sizes, are located to the west of the Danube in Újbuda, Budapest's eleventh and most densely populated district.
Highlights of the residential estate are its ample green spaces and colourful façades. The estate is set to be a vibrant addition to the area with facade colours that reflect the neighbourhood’s dynamic nature. The heating and hot water for the apartments will be supplied by district heating.
EC-B series delivers efficient operation
EC-B series cranes are ideal for residential projects like this one. Transport, assembly, handling performance, and safety – the flat-top cranes effortlessly bring together all the requirements of modern construction sites. They cover a wide performance spectrum, ranging from small city to large transhipment cranes. The cranes used in Budapest offered maximum lifting capacities of eight, ten and twelve tonnes.
Intelligent assistance systems supported the crane operators in carrying out precise and safe lifts. A prime example of this is the fine positioning mode Micromove, which enables precise and careful placement of loads. The EC-B’s ergonomically designed LiCAB crane operator’s cabin with unrestricted visibility ensured that the crane operators were able to do their job comfortably and with the best possible view of the site.
