Pressing issue solved by Terex Superlift

Three press components each weighing at least 200t have been lifted out of a factory in Germany using a 650t Terex Superlift 3800 lattice boom crawler crane.

Crane company Viktor Baumann employed the crane to lift two 270t components and one 200t components from an SGL Carbon facility in Bonn, at a working radius of 26m.

The Terex crane was assembled by a team of five at the SGL premises, using a 220t assist crane. It was set up with an SSL configuration, a heavy 48m main boom, and a 36m SL mast. 165t of counterweight was used on the crane’s superstructure, with 320t on the SL counterweight tray.

Liebherr provides right chemistry for Karl Scholl

German crane company Karl Scholl has targeted the chemicals industry with the addition of a 300t Liebherr LTM 1300-6.2 mobile crane to its fleet.

The LTM 1300-6.2, with a 78m telescopic boom, replaced the company’s 250t LTM 1250-6.1, providing higher load capacity and an additional 6m in boom length.

The crane, now the largest in the fleet of Heidelberg-based Karl Scholl, is said to be the smallest luffing jib crane on the market. It was supplied by Liebherr’s Ehingen facility.

The long telescopic boom and luffing jib make it particularly suitable for use in the chemicals industry, said the company.

Liebherr takes to the Autobahn

German crane company Autokranverleih Pengel has used its new 220t Liebherr LTM 1220-5.2 mobile crane at a motorway construction project.

The LTM 1220-5.2 replaced Pengel’s LTM 1160/2, previously the largest crane in the company’s fleet. The greater load capacity of the LTM 1220-5.2 was one of the reasons for the acquisition, said the company.

After being delivered in September, the crane was used at one of the largest construction sites on the A14 Autobahn in the north-east of Germany.

Liebherr puts wind in the sails of power plant

A 1,200t Liebherr LTM 11200-9.1 telescopic boom has been used to install a wind power plant in Germany.
Crane company Karl Hartinger Kranbetrieb, based in Warburg-Rimbeck, used a nine-axis LTM 11200-9.1 to install a 3MW Enercon E-101 wind energy plant in Preussisch Oldendorf, in the north-west of Germany.

The heaviest part of the plant was the machine housing, which had to be mounted to a hub height of 99m, with the total load including lifting gear and hook block at 66.5t.

The telescopic boom with Y-pattern guying was extended to 82m, mounted with a 31.6m lattice jib. The LTM 11200-9.1 also features a 6.5m-long hydraulic luffing lattice jib, which was well-suited to the project.

Karl Hartinger crane operator Tjerk Thomiczek said: “The hydraulically luffable lattice jib is unbeatable on this crane, because I can set up the entire E-101 from a single position. I never have to reposition – that’s a huge advantage. Over the course of the installation, the extension was reduced from 19m to about 10m.”

Sennebogen helps to build bridges in Russia

A Sennebogen 7700 crawler crane has been used to construct an 800m-long motorway bridge in Russia.
The 300t crane was delivered by LLC Lonmadi Saint Petersburg, Sennebogen’s sales and service partner for Russia, to construction company BaltMostStroy in the second half of 2013.

The job included lifting prefabricated steel parts weighing up to 100t onto the concrete foundations of the bridge, which is part of the new A121 motorway being constructed between St Petersburg and Priosersk-Sortavala.

The Sennebogen 7700, which features a 41m boom and auxiliary jib, was required to navigate hilly terrain while lifting the parts perfectly horizontally, and accurate alignment was necessary to securely place the chains and straps. Stability was provided by the 135t ballast and 8m-wide crawler undercarriage of the crane, while lifting was driven by a 313kW Caterpillar diesel engine with two 220kN winches.

Manoeuvrability of the crane is improved by the compact upper carriage, which is the largest component of the 7700 and has a transport width of 3m. The boom sections, which feature a self-assembly system for quick set-up, and the Starlifter undercarriage have a maximum width of 2.43m, making transportation easier.

Southern expands fleet with Tadano all terrain

Houston’s Tadano America Corporation sold an ATF 90G-4 all terrain crane to North Carolina company Southern Crane.

Southern opted for the ATF 90G-4 as the 168ft main boom combined with the 59ft jib length enables a quick set-up and take-down, even with limited space, said company president Earl Johnson.

A recent project for the new crane was unloading a 48,000lb communication building, which will be transported to the cell site and set again using the ATF 90G-4. The lift required the use of the full 49,163lb counterweight.

Based in Raleigh and formed in 2003, Southern Crane now operates more than 16 cranes ranging from 28-190t.
