Abstract (en)
[origin: EP2223882A2] The method involves placing an additional device on ground in alignment with a main jib of a mobile crane and holding a raised partial piece in an inclined position. The additional device is pulled into a horizontal position using a hoist cable fastened to an end of a partial piece facing away from the mobile crane and guided over a roller such that the partial piece of the additional device and the main jib of the mobile crane are aligned behind one another in orientation. The preassembled additional device is connected to a head of the main jib. Independent claims are also included for the following: (1) an additional device for attachment to a main jib of a mobile crane (2) a displacement device for displacing an additional device transverse to a longitudinal axis.
