Raimondi takes the heat in the UAE
4 April 2017 by Sotiris KanarisA new Raimondi MRT152, designed with hot climates in mind, was erected on the jobsite of the Novotel Sharjah Expo Hotel, in the United Arab Emirates, where it is scheduled to remain for 12 months.
Klampfer Middle East was awarded the contract to build the hotel in July 2016. It will include 200 rooms, a business centre and two meeting halls.
The tower crane will be tasked with the load lifting of shuttering materials, steel reinforcement, curtain wall components, pallets of blocks and cement, bags of sand, and scaffolding.
“The MRT152, with its small footing size and mast size relative to its capacity, has been a huge bonus. This crane’s positioning has been less intrusive on the building it is being used to construct. The free-standing height of 44m provides the contractor considerable structure to build without having to worry about ties,” said Günther Hinterberger, managing director at Klampfer Middle East.
Raimondi said the Middle East market is very important for the company, so during the design phase it takes into consideration all the aspects related to cranes operating optimally in extremely hot climates.
Domenico Ciano, technical director, Raimondi Cranes said: “The electrical motor was designed and produced to be able to perform well at high temperatures. Using climate-appropriate materials, the motors are equipped with an intelligent cooling system under the monitoring of the crane control system.
“One good example of how our control system adapts to the heat is that the fans continue to work even when the movement is stopped until the motor reaches a safe temperature. In the event that the fan motor malfunctions for any reason, the operator can be advised by an alarm and the crane ceases movement in a safe manner.”
Additional notable climate-specific features of the MRT152 include the gear box, electrical box and electrical components, together with the steel frame itself. The gearbox is filled with special oil that assures good lubrication despite high temperatures, and the electrical box and electrical components are installed inside a cooled box done by simple fans or by an air conditioning system. From structural point of view, the MRT152 Raimondi crane is built using steel that guarantees safety and stability in temperatures exceeding 50°C.
