Tower crane specialist Comansa has announced a slew of improvements to its 11LC flat-top cranes, adding features and enhancements to introduce the new generation of the range.
The manufacturer said in a statement that the new features include enhanced ergonomics thanks to new and simplified accessing elements not only to the cranes’ cathead, but also to the jib sections for easy access to the trolley. A new single trolley is now available as an option, which features a manual single-double reeving change by the operator directly from the ground.
The 11LC range now comes with new drives in the hoisting winch and trolley, which give linear movements thanks to attached potentiometers. This makes it possible to easily move and precisely position sensitive loads. Also, a new version of the 18kW hoist mechanism has been added to the 6t versions of the crane, requiring less power supply while maintaining drum capacity and speed features.
For reduced speed lifts, a power lift system now comes as standard and improves the load diagram by 10%. For higher speeds, optional 24kW and 37kW hoist motors feature the Effi-Plus system which significantly increases the hoisting and lowering speeds for light loads without increasing power or consumption.
Comansa’s statement added that another “significant innovation” is the new “M” sized CUBE cab together with a resized and redesigned platform for easier erection and maintenance. The cab has a fully glazed front designed to give a complete view of the load and the work area. The seat positioning and body posture have also been improved for greater comfort of the operator.
A new feature introduced in Comansa’s 11LC range is the optional Quick Set system, which is already available in the brand’s 21LC series. This system reduces the set up and calibration times for a crane with easier, safer and more intuitive adjustments for faster and less labour-intensive calibration.
The 11LC series continues to come in four variants – the 11LC90, 11LC132, 11LC150 and 11LC160, with a new 6t version of the 11LC150 the only addition. The new 11LC range was recently officially released online to European customers and the manufacturer added that some of its new features will also soon be expanded to the 16LC range.
