TOWER CRANES Ӏ BAUMA 2025
ZOOMLION
Chinese manufacturer Zoomlion showcased its R800-40 flat-top at Bauma. It is Zoomlion’s largest- tonnage model available in Europe and is aimed at bridge, powerplant and stadium projects. It has a maximum load capacity of 40t and a jib length of 80m. The tip load is six tonnes and it can hoist up to 140m a minute. The R800-40 is produced in
China and assembled in Germany. This, Zoomlion says, ensures rapid delivery times. The crane is backed by full-lifecycle servicing. The crane is EN14439-
compliant and can be spec’d with a range of safety systems and smart data controls. These include zoning and anti-collision systems, plus a hook video system. The crane also offers anti-swing functionality, protection against sudden unloading, real-time monitoring of working conditions, dynamic deceleration, plus a ‘Zoom Plus’ function that boosts the load curve by ten percent. The R800-40 uses all-pin connections to facilitate quick
Liebherr’s
520 EC-B Fibre helped showcase Liebherr’s fibre rope developments
assembly/disassembly. The cab measures 2.5x1.5x2.2m and has air conditioning, heating and adjustable seats.
MANITOWOC US manufacturer Manitowoc used Bauma to show its Potain MR 309 luffing jib crane to the world. The 16t capacity crane was announced in 2024 but has not been seen by a global audience until now. The MR 309 comes in two
variants, 16t or 25t, with a 60m jib, and a tip capacity of 3.4t. It has a 2m mast section and there’s up to 49.2m of free-standing height under pivot. The crane can lift 4.3t at 55m. Manitowoc says the crane offers
a reduced out-of-service radius (from 12 to 9.5m) and minimises anchorage frame requirements. It comes with Potain’s Connect telematics system and CCS control system as standard. The Potain MR 309 has a jib that can be mounted horizontally in either one or two parts to minimise space requirements during erection.
Platforms and steps are designed to enhance worker security and efficiency while the counter jib ballast is installed at working height, facilitated by built-in slinging points and a self- centring system. A redesigned luffing mechanism
aims to streamline assembly, says Manitowoc, while an integrated jib-end basket enables more secure installation and maintenance. At Bama Potain also announced
its largest Potain luffing jib crane for the European and North American markets: the MR 819. It has up to 70m of jib available and a maximum capacity of 64t – double that of the current largest Potain luffer (the 32t capacity MR 608B and MR 618).
The design of the MR 819 drew heavily on the design of the MR 309, resulting in an out-of-service radius of between 16 to 18m. Using a dozen five-metre sections of Potain’s new 2.45m, K 880 mast system, the crane can be erected at a freestanding height of 65.6m with jib configurations up to 50m, or it can be configured
