COMANSA has launched a new model tower crane designed to work in projects, in which it is necessary to lift heavy loads. The new 21LC1050 is offered with versions of maximum load of 25, 37.5 and 50 tonne, and can be erected with a reach of between 30 and 80 m with configurations every 5 m. <p></p><p>In addition, an optional jib configuration is available allowing a special reach of 85 m. The characteristics of load, reach and mechanisms of the 21LC1050 make this model ideal to offer an optimal result in large industrial or mining projects as well as for the construction of buildings with prefabricated and steel structures of great tonnage. The design of the slewing (horizontal) part of the 21LC1050 is similar to that of the successful 21LC750 and 21LC660. Instead of having a cusp element, the jib and counterjib join directly on the slewing part, which allows a much faster and safer assembly. The 21LC1050 also shares a large part of the jib and counterjib sections with its µlittle siblings¦ 21LC750 and 21LC660, which allows optimising the investment to customers who already own these models.</p><p>Among the novelties presented by the 21LC1050 is the design of its counterjib, which, like the jib, allows numerous different configurations to better adapt to the needs of each job. Always having a counterjib radius as short as possible avoids possible interference with buildings or other cranes present in the same project, thus increasing safety. The complete structure of counterjib consists of five modular elements that allow up to six different configurations. In addition, the counterjib radius in all its configurations can be reduced by one additional metre with steel counterweights, which are offered as an optional element. The 21LC1050 comes standard with the new CUBE cab in its XL version. </p><p></p>
