The Arora Group is building a new 14-storey hotel next to Terminal 2 of Heathrow airport in London, since May 2017. An essential part of the works is being held by a 21LC750 tower crane, supplied by rental company City Lifting, dealer of Linden Comansa in the UK.
To lift the heavy prefab modules of up to 13,200 kilos, City Lifting installed in Heathrow a special model of the 21LC750 crane, with maximum load capacity of 50 tonnes instead of the regular 48 tonnes. This increase in the load has been possible, thanks to a new and lighter trolley/hook set and the use of compact wire rope, which improves not only the maximum capacity but the entire load diagram. This design has been applied on this 21LC750 after a brand new model of large tower crane that Linden Comansa will launch very soon.
The 21LC750 in Heathrow was erected with a freestanding height of 51.3 m and jib length of 55 m. With such configuration, de jib-end load of this special model is 16,200 kilos, being able to lift up to 17,280 kilos when using the PowerLift system, which comes as standard in all Linden Comansa flat-top cranes.
Trevor Jepson, owner of City Lifting, says, “The 21LC750 at Heathrow Airport is the largest flat-top crane in the UK. We are convinced that when the crane finishes its job in this project, we will receive plenty of rental enquiries, because the trend in construction is to use heavier prefabricated units and machines like the 21LC750 will be more necessary for construction companies to work in a quick and efficient way. This model is the perfect addition to our tower crane fleet, which includes 43 units from Linden Comansa.”
