BAUMA 2025 Ӏ TOWER CRANES
couplable double trolley and is available in two variants: the two- fall model Wolff 8095.25, with a maximum lifting capacity of 25 tonnes and a tip load capacity of 10.5t (with Wolff Boost at an 80m jib length); and the convertible two- and four-fall model Wolff 8095.40, with a double, automatically couplable, and separable trolley and a maximum lifting capacity of 40t. A 110kW hoist winch provides operating speeds of up to 160m/min. The jib length can be flexibly adjusted in five-metre increments between 30 and 80m. The crane has a tower connection for 2.90 x 2.90m TV 29 tower elements which, when combined with the next larger Wolff tower element (TV 33), enables freestanding tower heights of up to 100m.
Another debut on Wolffkran’s stand was the Wolff 8038 Clear - a new 560tm class flat-top tower crane, the largest flat-top in Wolffkran’s portfolio to date. It has a 20t maximum lifting
capacity and can lift 3.8t at the maximum jib length of 80m (4.2t with Wolff Boost). An optional extension can increase the jib length to 85m, where it can still lift 2.1t at the tip. Its optimised patented jib design
reduces assembly weight. A tool- free plug connection on the top chord, bolt depots for overhead installations, and additional platforms for divided jib assembly are designed to make setup easier. Wolffkran has also revised the design of the lower chord construction to save around ten percent in material costs and reduced assembly weights. As a pure two-line crane, the
Wolff 8038 Clear can be ordered with either a 75 kW or a 110 kW hoist winch, enabling operating speeds of up to 132 m/min or 190 m/min respectively.
A US-version with a 110 kW hoist winch is also available. The crane is equipped as
standard with a 2.3-metre tower connection but can also be mounted on a 2.0-metre tower to fit into elevator shafts. It can be transported on six trucks. Also on the Wolff stand was the
new Wolff 7021 Clear, a flat-top in the 224mt class. It is the evolution of the Wolff 7021 FX prototype shown at Bauma 2022. It is available in two versions:
the Wolff 7021.8 Clear with a lifting capacity of 8.5t, and the Wolff 7021.10 Clear with a lifting capacity of 10.5t. A third 12.5t version is in development. The crane has a tip load
capacity of 2.1t (2.3t with Wolff Boost) at 70m of jib. The jib can be extended between 25 and 70m in 2.5m increments. The Wolff 7021 Clear is equipped with two slewing gears and, depending on the version, is available with 45kW (8.5 and 10.5t) or 67kW hoisting gear (12.5t), achieving a working speed of up to 94m per minute. The crane is primarily aimed at
the European market and can be transported on three trucks. To improve assembly and
accessibility the ballast frame with the hoist winch can be assembled /disassembled on the stationary crane rather than on the ground via a quick connection system. Another new Wolffkran crane was the Wolff 550 B luffer which fills the gap between Wolffkran’s 355 B and 630 B. Initially, the 550 B will be launched with a 110-kW hoist winch, enabling a maximum lifting capacity of 30 tonnes in two-fall operation and 15 tonnes in single-fall mode. At the tip of its maximum 65-metre jib, it can lift five tonnes.
By the end of the year
Wolffkran plans to offer the 550 B with a more powerful hoist winch
Liebherr’s 620 HC-L luffer
enabling it to lift up to 36 in two-fall operation. Additionally, there will be a US version with a 132-kW hoist winch. The Wolff 550 B has a hook path of 920m (single-fall) or 460m (two-fall) and a lifting speed of up to 200m per minute. It comes as standard with a 2.3m tower connection, allowing freestanding heights of nearly 52m. When mounted on a 2.9m tower, it can reach up to 82.2m without additional support. The luffer is available for order
starting in June and should be launched in Europe, the US, and the Middle East later this year
LIEBHERR
Another spectacular stand at Bauma belonged to manufacturer Liebherr. The stand was the biggest at the show and multiple tower cranes were on display. Representing Liebherr’s luffers was the 620 HC-L; Liebherr used Bauma to mark a major update to its HC-L series with the new 440 HC-L 12/24, 440 HC-L 18/36,
