Designing New Solutions The Flatstream Tower Crane 21LC1050, which has been recently introduced (September 2018), has made it possible for Comansa's R & D team to apply some of these developments to the two most successful cranes. In this way, models 21LC660 and 21LC750, designed primarily for large industrial projects, energy, mining and construction, significantly improve their performance.
The 24, 36 and 48-tonne versions of both models have found that their maximum capacity has increased to 25, 37.5 and 50 tonnes. This improvement, achieved thanks to a smaller diameter cushioning cable and an optimum design, not only increases the maximum load capacity of the crane, but also improves the number of loads, including peak loads.
Likewise, the Spanish applies a large modularity counterpart used in the 21LC1050 model, enabling up to six different configurations according to the pen's length. Thus, for example, when the 21LC750 crane is mounted on a 50 meter boom, the contrast of the radius is instead of 25 meters instead of 31 of the previous model.
Models 21LC660 and 21LC750 (except 21LC660 version 20t) incorporate a new 132 kW engine with speeds up to 300 meters per minute.
"New" 21LC660 and 21LC750 are now available worldwide and are supplied as standard with the XL size CUBE cab.
