The 21LC1050 features high speed hoist mechanisms (up to 300 m per minute/984 ft) and capacity for 1,570 metres of wire rope (5,150 ft.), making it the right choice for high rise construction. With its single-double trolley system with automatic reeving change, the crane always has an optimized load diagram. Working with the simple (or front) trolley, the crane improves its tip loading capacity and reaches higher hoist speeds. With the double trolley (front plus rear), the crane can work with the heaviest loads.
A new modular counterjib was designed for the 21LC1050, which allows up to six different configurations to adapt the crane to different needs and with increased safety. Thus, when the crane is assembled with a maximum jib length (80 metres/262.4 ft), the counterjib radius is 31 metres (101.7 ft), and can reduce to 27 (88.6 ft) when the jib length is 50 metres (164 ft). This will be shown at Bauma.
The 21LC1050 flat-top is the latest high capacity crane launched by COMANSA, and is yet another step forward in the company's strategy to adapt its range to global construction needs. Ten years ago, COMANSA's catalogue was formed by small and medium size flat-top cranes and three luffers, with maximum load capacity of up to 24 tons (52,900 lb). Since then, COMANSA has developed a new range of luffers, a new series of medium size flat-tops, and its heavy load range, including a 90-ton flat-top (198,410 lb).
Today, COMANSA offers 19 flat-top models and 6 luffing-jib cranes for all types of construction projects and has a leading position in the high capacity range. Besides the new 21LC1050, COMANSA has launched the LCL700 luffing jib crane, with maximum load capacity of up to 64 tons (141,090 lb), and has upgraded the flat-top models 21LC660 and 21LC750 to load up to 50 tons (110,230 lb).
Tower crane manufacturer COMANSA and its German dealer and crane specialist BKL Baukran Logistik will join forces for the third time and share booth FS 1103/1 at bauma 2019. The relationship between the companies dates to 2011, when BKL purchased six COMANSA flat-top cranes with a maximum load capacity of 8 to 18 tons. Soon afterwards, BKL became a COMANSA dealer in Germany. It will now be purchasing the 21LC1050 for its rental fleet.
