During the Bauma trade show, the Spanish manufacturer of tower cranes Comansa announced the arrival of a new model in its flat-top range. This crane, named 21LC1400 will be available worldwide from September 2019 in two versions, with maximum load capacity of 50 or 66 t. Like the other recent models of the brand, the 21LC1400 will feature a modular design of the counterjib to significantly reduce the counter-radius in constrained jobsites. A new single and compact trolley has also been designed and will replace the former Comansa double trolley system. The main expected application of the new cranes is to work in PPVC and infrastructure projects and on the sites where is necessary to lift very heavy loads.
Joseph Patton has been appointed as Sales Manager of tower and luffing-jib cranes for Comansa’s branch in North America. He will be based in Charlotte, NC, and will work with Bill Carbeau, VP of Business Development. Prior to joining Comansa in January 2019, Joseph worked as a Lifting Specialist for Mazzella Lifting Technologies, a supplier of overhead cranes, hoists and engineered lifting devices.
The Spanish tower crane manufacturer Comansa will be exhibiting at Bauma its latest model, the 21LC1050 flat-top tower crane. This model can load up to 50t and has a maximum radius of 80m.
Available for purchase since September 2018, the 21LC1050 has been designed to work in large industrial or infrastructure projects as well as in construction with heavy precast or steel structures.
The 21LC1050 is delivered equipped with the new CUBE cab in its XL size. It has a fully glazed front and offers excellent working comfort. It will be exhibited at ground level for all visitors to see its ergonomic qualities and usable space.
AMCS technologies installed its DCS 60 anti-collision and zoning system on a new model of Comansa crane, the 21LC1050 with a maximum load capacity of 50 tonnes. The tower crane is currently working at Högdalens värmeverk, an existing Combined Heat and Power plant located south of Stockholm and it will help to replace one of the boiler of the plant for newer technology. In addition to mobile cranes, a Liebherr 280 EC-H crane with 35m of jib and 56m hook height will assist the Comansa crane with 65m of jib and 73.3 m hook height.
Comansa has launched two new models of luffing-jib cranes at Bauma China Trade Show in Shanghai. The new luffers are the models CML280 and CML310, developed to cover the increasing demand for 18 and 24-tonne luffing jib cranes in Asia and the Middle East. The machines will also be available in Africa and South America. The cranes feature a counter jib of only 7.3 metres, that is an important advantage in congested sites.
In addition to the new luffing-jib cranes, Comansa has also announced the upgrade of its two flat-top cranes. The models 21CM335 and 21CM550 have been both upgraded from maximum load capacity of 18 tonnes to 20 tonnes.
Contractor ITB Nigeria is equipped with 6 Comansa cranes for the construction of the “Azuri Peninsula” apartments. The complex is a part of the Eko Atlantic project, a business and residential city under construction on an artificial peninsula in Lagos, the Financial Capital of Nigeria. This project, leaded by the State of Lagos and the Chagoury Group, will allow Africa’s most populated country to win around 10 square kilometres of a land that was lost to the Atlantic Ocean.
Currently six Comansa flat-top cranes are working on the “Azuri Peninsula” complex, which is being built at the Marina District, one of the new ten districts of this city. All the machines belong to the fleet of the turnkey contractor ITB Nigeria FZE and have a maximum load capacity of 18 and 20 tonnes. The cranes are working on the construction of the three towers that form the complex of more than 140 metres in height and up to 32 floors.
Among the six cranes, two are model 21LC550, one is 21LC335 model and the remaining three are 21LC290 model. All of them were erected initially with low heights but as the buildings were growing taller, the ITB Nigeria team used hydraulic jacking cages to jack-up the machines. The cranes are now working at their maximum height, reaching the tallest up to 163.5 metres.
All the six cranes are equipped with the Effi-Plus system, which increases the hoisting speeds with light loads and Comansa’s PowerLift System, which improves the load diagram of the crane by 10%. “The podium of the building is formed mainly by precast elements from 6 to 8 tonnes and concrete beams of different sizes with maximum weights up to 13 tonnes. For its construction, the PowerLift System had to assist us many times in certain operations in which we required a 10% extra capacity,” explained Paul Kattar, Tower Crane Manager at ITB Nigeria.
The cranes are working 24 hours a day, lifting steel structures during the daytime and helping with the concrete works during the night.
The Spanish tower crane manufacturer Comansa just launched a new flat-top model, available in three versions of maximum load (25, 37,5 and 50t), with a reach between 30 and 80m and up to 85m with a special boom configuration. Its maximum load of 50t makes the 21LC1050 the biggest Comansa 2100 Flat-top of the range. As the main novelties, its counter jib design has been modified among other things, to allow many configurations in order to adapt itself to the needs of each jobsite. Indeed, a shorter counter-jib avoids risks of interference with other cranes or buildings. This machine is also fitted with a new cab CUBE in XL version with the front fully glazed, which offers a better use comfort for the operator. As the previous Comansa flat-top cranes, the 21LC1050 is supplied in standard version with the Powerlift system, which improves the input/out diagram of 10% and not exceeding its working load limit. This way, if the final charge of the 25t model is up to 10,8t, when the crane operator activates the Powerlift system from the cab, the maximum load on jib end reaches 11,88t.
The tower crane manufacturer, after many years of using the Linden Comansa brand name, has decided to return to its original name: Comansa. This change will apply across the full range of products and at the company’s headquarters in Spain as well as in the United States and China.
As a result, cranes manufactured in Pamplona, previously marked under the Linden Comansa brand, and cranes manufactured in Hangzhou, China distributed under the name Comansa CM, will be know from now on as Comansa.
“The Linden brand and system, and all they entail, are part of our DNA. In fact, Comansa is the only manufacturer whose range of horizontal jib cranes consists solely of flat-top, pendant-free design, which was undoubtedly one of Linden’s most outstanding features. And, if there is one think that characterises Comansa cranes, it is their outstanding modularity, just like Linden cranes. That is why Linden is still very much a part of the philosophy of all our products, even though it no longer appears in our brand name,” explains Alberto Munárriz, CEO of Comansa.
