Linden Comansa launched its new 21LC335 flat-top tower crane, which is part of the LC2100 series. This new tower crane is the result of the review of the 21LC290, a model that Linden Comansa produced with success since 2002, and which will be replaced by the 21LC335. Both cranes feature similar characteristics in terms of range (up to 74 m - 242.8 ft), maximum freestanding height (64.5 m - 212.9 ft) and versions depending on the maximum load capacity (12 and 18 t - 26,450 and 39,680 lb). The changes made as a result of this review have led to an important increase of load capacity with maximum reaches under 70 m (229.7 ft). For example, the 21LC290 18t with a 50 meter jib (164 ft) can load 5,300 kilos (11,680 lb) at the end of the jib, while the new 21LC335 18t with same jib length loads up to 6,600 kg (14,550 lb), almost 25 per cent more. With this same 50 m jib configuration, the 21LC290 moved the maximum load of 18 tonne (39,680 lb) up to 16.3 m (53.5 ft), while the 21LC335 moves the maximum load up to 19.6 m (64.3 ft), 20 per cent more.
The 21LC335 crane comes standard with a Effi-Plus high speed hoist mechanism that reaches speeds of up to 150 m (492 ft) per minute, although there are other optional engines that can reach 228 m (748 ft) per minute. This also comes with the PowerLift system, that allows to improve the load diagram up to 10 per cent with reduced speeds.
