New Comansa luffing jib tower crane

Spanish tower crane manufacturer Comansa is expanding its range of luffing jib cranes with the launch of the LCH300. The crane is Comansa’s first hydraulic model and has a maximum load capacity of 16 tonnes and reach of 60 metres. It will be showcased at the Bauma trade show in Munich, Germany at the end of October.

The LCH300/16 t is available in various versions: embedded; supported on bases of six or eight metres; or movable. The crane can be assembled with 2.5 x 2.5m tower sections. Its modular jib has a reach of 25 to 60 metres, with configurations every five metres. It has a minimum working radius of four metres and a minimum radius of nine metres when out of service.

It has manual transmission combinations of 1T (direct pulling) and 2T. The maximum load capacity is eight tonnes with the 1T configuration and 16 tonnes with the 2T configuration. The maximum load at the jib end is 3,400 and 3,150kg, respectively.

The luffer moves the jib and counter jib jointly by a hydraulic cylinder at the cathead and jib hinge assembly. The hydraulic pump unit is located on a movable platform in one piece.

From the cabin the 50kW (standard) and 65kW (optional) lifting mechanism is clearly visible. Comansa’s Effi-Plus technology means it is possible to increase the speed of the lifting mechanism without affecting consumption. This allows loading cycles to be reduced thus improving productivity, says Comansa.

The design of this new rotating part - jib, cathead and counter jib - as well as the mechanism, cabin and hydraulic unit platforms, optimises the transport of this model, which may be supplied by eight trucks or containers.

The LCH300 incorporates its CUBE Cab (L or XL) with Split type air conditioning. The cabin platform, like the lifting and hydraulic unit platforms, can be transported in a single piece.

Luffing jib tower cranes offer optimal performance where horizontal jib cranes cannot move loads freely due to space limitations. Now, with the incorporation of the LCH300 hydraulic model, Comansa says the luffing mechanism is optimised to offer even greater performance, efficient assembly, as well as reduction of the radius when out of service.
