Txillida Leku Maneuver
Sometimes the maneuvers we perform do not require large cranes, nor large technical and human deployments.
This is the case of the maneuver performed recently at the Txillida Leku Museum. Thanks to our versatile crane fleet and experienced personnel, we were able to change the location of some sculptures that are part of the collection.

LTM1300-6.2 of 300 t to provide gravel to a “Piling Rig” (gravel column equipment) which moved along the estuary on a pontoon. This crane used a clamshell bucket assisted by the double winch of the crane to load material from mainland and subsequently download it on the pontoon. This gravel was injected at high pressure to reinforce the sea bed with a large number of piles.

AC40 of 40 t and a 3-axle crane truck working together to assemble a platform which was used as stage and springboard for the Red Bull Cliff Diving event which took place at La Salve bridge in September 2019.
Client: Construcciones Amenabar, S.A.
The LTM1350-6.1 of 350 t and the LTM1095-5.1 of 100 t unload and assemble a tower crane in the inner courtyard of the Banco Santander building. The crane had a maximum height of 60 m and had to raise a maximum weight of 7.5 t above the height of the building itself, which was around 37 m high.
One of the greatest difficulties in this manoeuvre was the assembly of the necessary equipment to carry out the manoeuvre, avoiding the large number of cables in this square to supply power to Bilbao tram.
The icons of a city such as Bilbao change and some disappear to give way to new realities. This is what has happened with the demolition of the old San Mames Football Stadium, which has been replaced with a new one. The icon we are referring to is the arch which rested on the grandstand. Four heavy-duty cranes, Demag AC 500/2, Liehberr LTM 1500 and 2 Demag AC 700 were used to disassemble it. The manoeuvre took two days, although the disassembly, as such, took approximately one hour. The 22 people who made up the Ibarrondo Group team spent the rest of the time on preparing the equipment to be used.
A manoeuvre of this kind also required the assistance of 4 lowboy trucks per crane to carry the necessary tools and counterweights. Two smaller support cranes, Demag AC 200, were used to fasten the structure of the arch to the cables of the bigger machines which had to lower it.
The technical department of the Ibarrondo Group planned the whole manoeuvre and carried out a virtual simulation in advance to avoid any unforeseen problems.
Description:At the Ibarrondo Group we are also prepared to meet the small needs of our clients. We have a fleet of City-type cranes to carry out manoeuvres in urban settings and small areas. These models provide wide mobility and manoeuvrability.
For this manoeuvre we used a Demag City AC 25. It involved installing a shipping container turned into a display in Plaza Euskadi.
Customer: Athletic Club
In order to prevent as much as possible some fans at the lower rows from getting wet on rainy and windy days, the club resolved to extend the roof of the new San Mames Football stadium.
With this work, the roof has been extended by 13 metres at the stands, up to 18 metres on both ends and 23 metres in the corners. Therefore the central “hole” has been reduced by half, from 8,000 to 4.000 square metres.
To carry it out, the Club’s contractor used the elevation means of the Ibarrondo Group. During the first phase, two cranes, Demag AC 500/2 and Liehberr LTM 1.500/8, both with 90-metre luffing jibs, introduced the 30 parts of the structure by raising them from the street, above the stadium, down to the pitch. Each of the parts weighed 11 to 13 tonnes.
Once inside, two Liehberr LTM 1.130 cranes handled the parts and placed them in their exact location. Some lighter cranes and other means of the Ibarrondo Group were also used in this space.
A permanent team of eight operators working for two months brought this manoeuvre to a successful conclusion in spite of the tight deadlines.
