TOWER CRANES Ӏ SECTOR REPORT


preinstalled as standard within the next two years.


Existing cranes can be j chord connection has been


redeveloped with a patented design to make the jib easier to assemble. Maximum component weights


of 7.9 tonnes further facilitate assembly, allowing all three Wolff 21 FX Family models to be erected with a 100-tonne mobile crane at a tower height of 40 metres. They are optimised for


transport with 40 metres of jib fitting in one truck and 30 metres in a shipping container. The hook block and trolley can


be transported and assembled as a unit.


The Wolff 21 FX Family cranes


are expected to be used both on the European market and in Asia. There will also be a US version with adapted electronics. The new Wolff 21 FX cranes are


the first Wolffkran models ready to operate the new High-Speed- Positioning-System as standard, which was demonstrated at Bauma on the 7021 FX. The High-Speed-Positioning-


System (HiSPS) is an electronic assistance system designed to prevent load sway, allowing for precise positioning of loads. The patent-pending technology increases safety and efficiency on the construction site and sets the stage for the autonomous cranes of tomorrow, says Wolffkran. For more information regarding the system see our operator assistance devices feature on p28. Wolffkran plans to deliver

unveiled the new Lumina crane cab at Bauma


retrofitted while, in a second phase, the system is also intended to be available for Wolff luffers. At Bauma Wolffkran also debuted the Wolff 8076 Compact trolley jib crane. It is a pure two- fall crane with a tower top around 10 metres lower than that of a Wolff Cross model, a maximum lifting capacity of 40 tonnes, and a tip load capacity of 8.4 tonnes at 80 metres. "We wanted to design a large yet economical crane and get the maximum capacity out of the steel structure,” says Wouter van Loon, product manager at Wolffkran. “That's why we opted for a low-top design, which we call Compact." New on the crane is the four-


chord design of the first three jib sections instead of the usual three- chord design. “This allowed us to optimise the transfer of forces along the jib and reduce individual components weights, resulting in around 40% higher lifting capacity than with the three-chord design,” explains van Loon. The Wolff 8076 Compact


connects to the 2.9 x 2.9-metre TV 29 tower system. Combined with the next-largest Wolff TV 33 tower system, a freestanding height of up 100 metres can be achieved. “We are evaluating a heavier lift


version of this model,” adds van Loon, “as well as one with a longer reach.” Both will be designed around the same basic components of the new Wolff 8076 Compact. At Bauma 2022 Wolffkran


also showed its newest luffing jib crane, the Wolff 235 B, which was released in 2020.


Utilising a new connecting frame it was shown on Wolff’s new TV 15 1.5x1.5 metre tower system. On a 1.5 metre tower system the 235B can have a freestanding height up to 41 metres.


Next to the TV 15 tower system


Wolffkran showed its 6x6 metre tower system: the TV 60. The tower section was developed in 2020 for a high-altitude dam project, where it served as a base for two 90-metre freestanding Wolff 1250 B luffing jib cranes.


NEW CLASS Also launching a new series of flat-top tower cranes at Bauma was manufacturer Raimondi Cranes who launched the Class 110 and the Class 150 range – represented by the T187 and the T537 respectively. The two new flat-tops were shown alongside the company’s new extended crane cab, the Raimondi Lumina X. Raimondi proclaims the T187


as a weight-optimised machine with best-in-class specifications for lifting capabilities and speed. It is the first of a planned eight cranes in the Class 110 series “The T187 represents a big


step forward for Raimondi as it has been designed as part of a full range of cranes – the Class 110 – and not as a standalone machine,” says Eng. Diego Borgna, CEO, Raimondi Cranes. “This approach has significant implications on both technical and operational levels.” Key to this is the modular design of parts combined with the interchangeability of the jib elements. "The T187 — as well as the


whole Class 110 — was designed with rental companies in mind,” adds Cristian Bain, commercial director, Raimondi Cranes. “The flexibility of choices, 8 tonne and 10 t, II/VI falls or permanent II falls, allows fleet rental companies to address a wide variety of needs and projects.”


The crane has a 67.5m jib length and a 1.61 tonne tip load (in UltraLift mode).


The crane has a newly designed reinforced tower that allows
