TOWER CRANES Ӏ NEWS IN BRIEF
16 years of experience in European
manufacturing and will initially focus on maximising production efficiency, quality control, and expansion under the ‘Made in Italy’ hallmark. The company has also just appointed an official dealer for the Veneto region of Italy: Tecno Edicasa. The appointment comes through a client partnership of over a decade with Italian construction crane rental, assembly and assistance company Tecno Crane. “Raimondi recognises the pivotal
role of a trusted dealership network; by leveraging Tecno Crane’s extensive experience and expertise in serving customers in the Veneto Region,” stated Maggioni. “We aim to enhance accessibility to our products and to better meet customer’s demand in the territory.” The dealership agreement was penned alongside the installation of the first Raimondi T187 flat-top tower crane in the country.
ballast frame and counterjib. This means Wolffkran has been able to reduce the assembly weight of the counter jib, too. Jib parts can now be transported
on the counter jib, while the counter jib railings do not need to be removed during transportation. This saves space and facilitates greater ease of transport. The crane can be transported in three trucks. According to Wolffkran, the Wolff
7021 Clear’s jib is easy to assemble and maintain, too. This is, in part, due to the upper and lower boom connection, that was introduced on the Wolff 6523 Clear. This system, Wollfkran says, also provides smooth transitions ensuring more fluid movement of the trolley for fine positioning of the load. The Wolff 7021 Clear is a double-
reeve crane and two versions are currently available: the 7021.8 – with a lifting capacity of 8.5 tonnes; and the 7021.10 – with a lifting capacity of 10.5 tonnes. A 12.5 tonne version is currently being planned. The crane has a tip load capacity of 2.1 tonnes (2.3 tonnes with Wolff Boost) at 70 metres of jib. The jib can be extended between 25 and 70 metres in 2.5-metre increments. Depending on the version, the Wolff
7021 Clear is available with 45 kW (8.5 and 10.5 tonnes) or 67-kW hoisting gear (12.5 tonnes) as well as with two slewing gear units, capable of operating speed of 94 metres per minute.
REDESIGNED WOLFFKRAN PROTOTYPE NOW MARKET READY Zug, Switzerland-headquartered tower crane manufacturer Wolffkran’s has launched the Wolff 7021 Clear. The crane was first seen in prototype form at Bauma 2022 (where it was called the Wolff 7021 FX). Since the initial prototype, the crane has been redesigned in response to talks with customers and operators. As a result the crane now offers improved assembly and accessibility, claims Wolffkran. The ballast frame and hoist winch can now be assembled/disassembled on the crane itself rather than the ground, as previously seen on the prototype. This has been made possible due to the use of a quick connection between the

cranes and fast-erecting cranes FM Gru. Verhelst says the partnership is the result of over 18 years of collaboration already and is confident that the exclusivity deal will strengthen its position in the market. Verhelst also enjoyed some television
coverage with one of its mechanics starring in the TV programme ‘The most dangerous jobs in Flanders’ shown on Belgian television channel VTM2 in December 2023. The image below shows the Verhelst mechanic at the end of the boom of a Wolff 7032 Clear.
