Embodiment Construction

[0035] In the descriptions in the following sections, with the help of the attached Figures 1 to 6 A specific embodiment of the method according to the invention for assembling a telescopic crane and an embodiment of the telescopic crane are described.

[0036]The required jib combination for a telescopic mobile crane is determined in the crane service plan. To extend a crane main jib, one or more boom extensions should be fitted on top of the main jib in order to prepare the crane for the planned crane work. The corresponding jib extension consists of individual truss elements 1, 1a, 1b, 1c, 1', 1a', 1b', 1c' which have been combined with one another before being transported to the installation location and which are mostly in in working condition. Possible preassembled boom extensions are, for example, main boom extensions or also fixed or pivotable fly booms.

[0037] In the central part of the crane present here, the complete jib assembly disassembled into the individu...

Abstract

The invention refers to an assembling mobile crane used on a construction site, especially a method of a telescopic crane. The mobile crane is provided with a main erector arm and at least one erector arm extension part supported on a transporting mechanism and comprising at least one truss member. The method comprises the steps of: moving the mobile crane and / or the transporting mechanism to roughly align at least one truss member of the main erector arm and the erector arm extension part; and connecting the main erector arm and the truss member by means of at least one traction mechanism, wherein the main erector arm swings to load traction for the at least one truss member and make subsequent assembly partially align axles of the connecting points of the main erector arm and the at least one truss member.

Description

technical field [0001] The invention relates to a method for assembling a mobile crane, in particular a telescopic crane, having a main boom and at least one boom extension on a construction site. Background technique [0002] Large telescopic cranes often use truss members as main boom extensions during crane service. Likewise, the truss members are often assembled into a swingable or fixed fly jib and mounted on the telescoping main boom of a telescoping crane. [0003] Due to the prescribed vehicle dimensions of mobile cranes in road traffic, the individual lattice elements are transported to the work site individually and are not mounted on the crane jib until they have arrived at the construction site. However, in order to assemble the individual truss elements on the construction site, auxiliary equipment such as auxiliary cranes is mandatory. Typically, optimal utilization of the transport volume of the truss elements is ensured by suitable transport systems which a...
