Method for erecting a crane boom

摘要

The method involves anchoring a fly jib of a telescopic crane (5) by anchoring stands and tensioning posts, where the crane has a spatial arm anchor. A main extension arm (10) of the crane is braced before connecting with the fly jib by the spatial arm anchor. The anchoring stands and an insulated base piece of the fly jib are attached to the main extension arm. The anchor is installed and tightened to connect the insulated base piece of the fly jib with the fly jib, where the fly jib is displaceably supported on carriages.
