BENNETTS CRANES


DEPLOYS WORLD’S FIRST POTAIN MR 309


UK tower crane hire company Bennetts Cranes has deployed the world's first Potain MR 309 luffing jib crane for the redevelopment of the 40, The Broadway office building in Westminster, London, UK. The crane was launched globally earlier this year and has now been utilised by Bennetts due to its ability to operate in tight spaces, lift heavy loads, and function with limited power thanks to its adjustable power supply. The MR 309 has a 55-metre jib and can be parked at a 9.5-metre radius. Other facets of the MR 309 that made


it suitable for the job are that it has no component weighing more than ten tonnes, enabling it to be erected by another luffing jib tower crane on site. It also needed to have a lifting capacity


of over 12 tonnes in order to dismantle the other luffing jib tower crane used for its assembly. The crane’s low moment force was also key as it was bolted to a steel grillage on top of a core structure. Additionally, with limited power availability, the MR 309 crane’s adjustable power supply, supported by the Power Control function, was necessary.
