New LC1600 Series from Linden Comansa

The Spanish manufacturer Linden Comansa is launching 3 new models of modular Flat-top tower cranes this month.

Linden Comansa keeps its high pace of work in the development of products and, a little time after presenting a new series of luffers, is now launching a new series of Flat-Top tower cranes. The LC1600 is being commercialized this October and will be formed by models 16 LC 185, 16 LC 220 and 16 LC 260, which will come in different versions of maximum load.


The LC1600 series has been designed with Linden Comansa's fundamental premises in mind: modularity and easiness of both assembly and transport. Due to its load capacity, between 8 and 12 tons, the new series places between the LC1100 (5 to 8 tons) and LC2100 (12 to 48 tons) families. In addition, the LC1600 family unites the advantages of both series with which it shares numerous elements.

The development of this new series implies in addition to the disappearance of two models of the series LC2100. The 21 LC 170 and 21 LC 210 cranes, with very similar characteristics to the new models as for jib length and load capacity, will stop being produced mainly due to the advantages applied in the LC1600 series, and to the even more competitive prices of the new models.

The cranes of the LC1600 series share the jib sections and the counterweights with those of the LC1100. The interchangeability does not end there, since the counterjib of the LC1600, more compact, is compatible with the one from the LC1100 series, allowing to reduce the counterjib radius of this one. In addition, the trolley and hoist mechanisms and the trolley-hook joint of the cranes from the LC1100 series can be used in the cranes of the series LC1600 series, which supposes a great advantage for those clients who own cranes of both series.

With the LC2100 series, the new family shares the 2 meter wide tower sections, as well as the climbing cage and the 4.5 and 6 meter wide cross bases. With a transition section, the cranes of the LC1600 family can be erected on 2.5 meter wide tower sections, to obtain freestanding heights superior to 100 meters.

One of the designed advantages of the series is that the cranes don't have apex element in strict sense. The first counterjib section is placed on the gyratory part and, once mounted, the first jib section joins in one end and the rest of the counterjib at the other. This beginning of counterjib, which also shelters the hoist mechanism, is more compact than the apex elements of both cranes that will not be produced anymore. Due to this, the transport speeds up and some unload maneuvers before the erection are avoided. This design, which saves costs in equipment and improves the labors of erection, is based on the 21 LC 750, the first Linden Comansa model without apex element.


The double trolley system of these cranes is similar to the one successfully used in the LC1100 and LC2100 series, though it has been adapted to maximum loads of 12 tons. The trolley-hook joint, with pre-installed reevings, comes in a frame to ease the assembly, transport and storage.

The hoist mechanisms include the Effi-Plus System, which improves up to 70% the speed of hoist and descend movements. With this system, the productivity during hoist operation is improved up to 27% without any increase in power or electricity consumption.

The jib sections are narrow, and the tower sections can be dismantled in panels, which eases the transport of the crane. In addition, the elements of the LC1600 have been designed by light erection weights (the heaviest element is 6 tons), which allows a faster and safer assembly.

The cranes of the C1600 series are the first from Linden Comansa to include frequency control in the slewing movement. This system makes the most of the energy, and therefore, allows a minor consumption, keeping the same maneuverability and identical sensations for the crane operator. In addition, the smaller size and less warming of the engine, as well as the use of the same brake and weathervane that most of Linden Comansa's cranes, minimize possible maintenance problems and search of replacements.
