For an unforgettable musical performance in a height of around 60 metres in January, thinking out of the box was in demand for the Munich mobile crane scheduling department. The special thing about it: At the music performance "Piano Vertical" the Swiss artist Alain Roche combines the soft strains of the piano with the harsh sounds of construction - while he and his instrument are suspended vertically under a moving crane.

The project posed two challenges for BKL's crane experts: overcoming obstacles almost 55 metres high, while ensuring maximum safety, including insurance.
The BKL team's solution was to use an MK 140. Configured with 9 tonnes of additional ballast and 45° angle position, the mobile construction crane achieved the radius of 40 metres and the hook height of 75.5 metres required to lift the artist and his specially adapted piano over the 33 and 54.1-metre buildings.

As BKL was the only crane supplier able to meet the high safety standards of the project, the contract was awarded without further ado. There was just one request from the Whitebox organisers that the team did not fulfil: for safety reasons, the artist was not lifted over the audience, who were sat in deckchairs and equipped with headphones. Nonetheless, with consummate skill, the BKL crane operator still managed to achieve the planned "thrill factor": by slowly swinging Alain Roche right in front of the spectators, he allowed them to get as close to the recital as possible.

BKL Frankfurt's mobile crane Grove GMK6400 successfully realized 35-ton hoisting for the construction of a heat storate system.

BKL fits the cover on the storage tank.
For the construction of a heat storage system on the Ingelheimer Aue between Wiesbaden and Mainz the Frankfurt specialists used a powerful Grove GMK 6400. The AT crane had to lift the 35-ton cover, with a diameter of about 12 m., onto the 36 metre storage tank. With the challanging lifting, the 6-axle crane, with a lifting capacity of 400 t and added MegaWingLiftTM, demonstrated its full potential, without taking as much of a footprint as a large crane. The 35-ton cover hovered in the air and due to the skill of the experienced BKL crane operator the huge cover could be placed in the exact predetermined position within a very short time.

Innovative System for district heating.
In order to ensure the supply of environmentally friendly district heating to the citizens of Mainz, Germany, a power plant will be built on the compound of Kraftwerke Mainz-Wiesbaden AG (KMW AG), that will produce heat and electricity from natural gas. The new heat storage system should also help make optimal, energy-efficient use of the generated heat waste. The water tanks can store the hot water, generated during electricity production for several days and if required, deliver it to the district heating Network. The construction project has an Investment volume of more than 100 Million euros. The commissioned construction company hired BKL to erect the heat storage tanks.

A royal assignment for BKL's fleet of Tower and mobile cranes.

BKL's ingenious Tower crane solution to renovate the facade.
Linderhof is said to have been a favourite castle of King Ludwig II of Bavaria. Surrounded by a magnificent landscape park in the Bavarian Alps, the palace attracts many visitors every year. The extensive mountainous terrain presented a challenge for the crane concept as the sloping site virtually ruled out a standard tower crane assembly. The crane experts therefore opted for a special tower crane combination from BKL's rental fleet. A 90 EC-B with a hook height of 40 metres, a 50-metre radius and a maximum load capacity of 6 tonnes was installed directly behind the Castle to lift the elements, weighing up to 3 tonnes each. For the second crane, the crane specialists deployed a 32 TTR with a hook height of 24 metres, a 30-metre radius and a maximum load of 4 tonnes. Its crawler chassis makes the self-erecting crane suitable for all terrains, enabling it to be set up at the slope.

Full BKL service and teamwork for the disassembly with an LTM 1350-6.1.
Once the renovation work was completed, the mobile crane team from BKL Munich dismantled the top-slewing crane with a Liebherr LTM 1350-6.1 mobile crane, as the most cost-effective alternative. The conditions at site meant, that the mobile crane had to be positioned in front of the palace, while the tower crane, that needed disassembling was behind the building. Therefore, the 350-tonne giant was specially modified to achieve the necessary hook height of 55 metres with a 40-metre radius. In order to lift the required 8.5 tonnes of maximum load, the crane specialists configured the mobile crane with 70 tonnes of ballast, a Y-telescopic boom guying system and a 12-metre extension on the main boom. The auxiliary crane was an 85-tonne-metre loader crane PK 92002-SH, which speeded up the process thanks to its small space requirement and short set-up time.
To avoid disrupting visitors to the palace as far as possible, the project planning, mobile crane and trucks had to be closely coordinated. BKL's highly trained team completed the disassembly and the whole return transport of the cranes in a single day.

Frost protection for King Ludwig II’s palace garden, Chiemsee, Bavaria.

Every autumn the park next to this magnificent building on the island in Chiemsee is made ready for winter. A LTM 1060-3.1 owned by BKL Baukran Logistik GmbH in Munich was driven to the largest of the Bavarian lakes with the job of hoisting large scaffold hoods over fountains, some of which are enormous, to protect them from frost. The mobile crane rolled onto the cargo ferry, which safely transported the crane to Herreninsel.
Since the mobile crane had to be assembled outside the giant drained water basins, a radius of 24 metres was required to erect the scaffold elements, which weighed over two tonnes. The driver had extended the boom on his mobile crane to 45 metres for this purpose to lower the loads over the fountains, measuring up to 13 metres in height. This required the crane control system to execute manoeuvres with millimetre precision as the scaffold components had to be positioned from a suspended position on the elements which had already been installed and then connected to them.

September 2018, BKL Frankfurt installs power poles for the overhead wiring of the test track for trucks.

As part of the joint project ELISA "Electrified, innovative heavy-duty traffic on motorways", the first german test track for trucks with current collector is established in Hessen. BKL Frankfurt received the order for the assembly of a part of the 231 power poles. A particular challenge were the space conditions at the operating site. In order to prevent the closure of a lane, the crane specialists used the narrow hard shoulder next to the motorway and provided a loader crane instead of a mobile crane, which scores with a lower supporting width and does not swing over the vehicle and thus out into the motorway. The team also transported the masts for the overhead wiring of the test track, which are between 13 and 14 metres long, from the storage place to the construction site.

In Lubmin, BKL's crane specialists were commissioned by the demolition experts at Mittelsdorf to install two tower cranes for the partial deconstruction of the inoperative power station: a high-top Liebherr 550 EC-H (51.1 m radius, 15.4 m hook height, 20/40 t max. load capacity, 12/11 t peak load) and a 202 EC-B (60 m radius, 34.6 m hook height, 10 t max. load capacity, 2.6 t peak load) from BKL's crane fleet. The team assembled the two tower cranes on the roof of blocks 7 and 8 with a 400 tonne mobile crane from the BKL fleet. Both cranes run on approximately 120 meters of track to transport the loads to every part of the building.
In the project in Lubmin, near Greifswald on the Baltic Sea, the cranes were used to dismantle the top floor of blocks 7 and 8, which were never put into operation. Wind turbines are now being manufactured in one section of the power station site.

JUNE 2018 - until summer the sized crane will set over 150 wooden modules weighing almost eight tons, from which a special hotel concept is realized in modular construction.
For this purpose, the construction crane stands on a parking level of the Berlin Ring-Center at the Frankfurter Allee. The team planned the provision of the 750 metric tonne giant with a radius of 80 m on a special steel construction and installed it supported by a 500-tonne-mobile crane from BKL's hire fleet.
