Method of assembling a crane and coupling section, telescopic boom and crane

摘要

The invention relates to a method of assembling a crane having a telescopic boom which has a coupling section, a telescopic cylinder supported therein and at least one telescopic section, wherein at least one telescopic section is transported to the site of deployment separately from the coupling section and the at least one separately moved telescopic section is drawn, in particular drawn slowly, into an outer section, in particular into the coupling section, in the assembly position by the telescopic cylinder by means of an auxiliary assembly head.

主权项

1. A method of assembling separate components of a crane having a telescopic boom which has a coupling section, a telescopic cylinder supported therein and at least one telescopic section detached therefrom, comprising the steps of
transporting the at least one telescopic section to a site of deployment separately from transporting the coupling section to the site of deployment, drawing the at least one separately-transported telescopic section into the outer coupling section, in an assembly position, by action of the telescopic cylinder and an auxiliary assembly head, connecting the at least one telescopic section with an auxiliary crane and bringing the at least one telescopic section into the assembly position for drawing in, and bringing an end piece of the at least one telescopic section into an inner space within the outer section by the auxiliary crane in the assembly position until a bolting system for bolting at least two sections contacts a collar of the outer section.
