Embodiment Construction

[0039] figure 1 Shows the front of a mobile crane 1 with a telescopic boom 2 at rest and retracted, comprising a trunk section A and other sections B, C, D, E, F and Section G, the arm head 5 is located in the last, innermost section G. Spacers 3A-3F are arranged on the top surface, and are located in front of sections A-F, respectively. The special design will be described in more detail below.

[0040] At this stage, explanations of concepts and definitions used in the context of the present specification will be given. The present invention, defined as a rope guide for a crane, aims at bringing the design of the guide and spacer of the rope guide into the appropriate technical field. In this sense, the guide and spacer constitute the subject matter of the present invention, and its characteristics and inventive points can be widely applied to all implementations using the design of the above-mentioned guide and spacer. In the present disclosure, "guide" should be under...

Abstract

A rope guide for a crane, in particular a rope guide for a telescopic crane, comprises at least one guiding element for a rope which extends from a boom head along the boom of the crane. The guide is characterized in that at least one of the guiding elements comprises a spacer which has, on its rope-sliding surface facing the rope and as viewed transversely to the direction of the rope's extension, a substantially round concave form. Embodiments have a spacer with one or more grooves which guide and accommodate the rope.

Description

technical field [0001] The present invention relates to a rope guide for a crane, more particularly the present invention relates to a rope guide for a telescoping crane. The rope guide is suitable for all crane ropes running on the jib of the crane, such as hoisting ropes of a crane. Background technique [0002] Typically, the hoisting ropes of the crane are guided across the top surface of the crane jib from the hoist in the direction of the head drum. As a result, it is necessary to prevent the rope from brushing the top surface of the crane, and various guides have been used in the prior art to solve this problem. Especially when the telescopic arm deforms under load, these guides assist the rope to be guided freely without contacting the top surface of the arm. [0003] In a known embodiment, rope rollers mounted on ball bearings are provided in the guide, on which the hoisting ropes run. Image 6 This design, known in the prior art, is shown showing the front of the...
