The 53 K fast-erecting crane was unveiled to the public for the first time at the Bern 2014 Construction Machinery Exhibition. The new design of the 50 mt class crane is based on the successful K series concept and closes the gap between the 42 K.1 and the 65 K. The new fast-erecting crane with a truss construction and improved erection kinematics delivers more power, variability and safety on site.
The 53 K achieves a maximum hook height of 31 m which is the top value in the 50 mt crane class. With the rapid climbing system, up to three complete tower sections can be inserted practically and safely. This means that the hook height can be adjusted to suit the site situation. With the 20° jib luffed position, the maximum hook height can also be increased to 43.1 m.
With a horizontal jib, the 53 K can be configured with seven different hook heights between 15.8 m and 31 m. This makes the new K crane ideal for use on multi-occupancy residential buildings with up to eight storeys.
