SECTOR REPORT Ӏ HIGH-RISE CONSTRUCTION
a hook path of 920m in 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. This allows freestanding heights of nearly 52m.
When mounted on a 2.9m
tower, though, it can reach up to 82.2m without additional support, making it an excellent choice for high-rise projects. And the Wolff 550 B is compatible with Wolffkran’s KSH 23 internal climbing frame, enabling the crane to climb nearly 27m in a single phase – significantly more than the 15.5m achieved by the standard climbing system. The KSH 23 reduces time considerably and lowers costs.
Initially the Wolff 550 B is
being launched with a 110-kW hoist winch, giving a maximum lifting capacity of 30t in two-fall operation and 15t in single-fall mode. At the tip of its maximum 65m jib it can lift five tonnes. “These lifting capacities are
market-leading in this crane class,” says Mohamed Abouelezz, Wolffkran’s head of business development and product management. “By the end of the year, we'll be raising the bar even further by offering the 550 B with a more powerful hoist winch, with which the luffing jib crane can lift up to 36t in two-fall operation. “Additionally, there will be a
US version with a 132-kW hoist winch.”
Adding to its suitability for high-
rise construction is the Flex Cab cabin, which can be mounted on either the right or left side of the crane. It was previously available only as a special customer request but is now standard equipment on the Wolff 550 B. Being able to select which side the cab is mounted simplifies construction site planning and is particularly beneficial for cranes that need to be climbed down after construction. The new luffing jib crane will be
available for order starting in June and is expected to be launched in Europe, the US, and the Middle East later this year. Wolffkran also showed another new tower crane at Bauma: the
