T-Profile Cable Routing on Crane Outer Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing cables on gantry-type cranes, such as RTG cranes, are costly and time-consuming due to the use of complex ladder structures made of stainless or acid-resistant steel, which require numerous parts and lengthy installation times, and also necessitate additional protective covers.
Innovation Solution
The use of T profiles fastened to the outer surface of the crane structure, with the transverse part of the T profile providing cable conduits open from the sides, replacing traditional ladder structures and eliminating the need for additional protective plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ladder structures are used to fasten cables, then cable protection and routing are achieved, but the structure becomes complex and installation time increases
Solution Approach 1:
The patent combines the cable routing function and protective covering function into a single integrated T-profile structure. The T-profile's vertical stem provides the mounting structure while the horizontal top surface simultaneously serves as both the cable conduit and the protective cover, eliminating the need for separate ladder structures and protective plates.
Solution Approach 2:
The T-profile is designed to perform multiple functions: it provides structural support for mounting cables, creates a conduit for cable routing, and offers protective coverage against impacts and sunlight. This multi-functional design replaces the traditional multi-component system with a single versatile element.
2Ease of operation
If traditional ladder structures with multiple parts are used, then cable routing is achieved, but installation cost and time increase
Solution Approach 1:
By merging the routing conduit and protective cover into the single T-profile structure, the installation process is simplified from multiple assembly steps to a single mounting operation. The T-profile is fastened directly to the crane structure with its stem, and cables are routed along its integrated top surface, eliminating the need to assemble and attach separate components.
3Object-affected harmful factors
If additional protective covers are added to cable ladders, then cable protection against impacts and sunlight is improved, but device complexity and cost increase
Solution Approach 1:
The protective function traditionally provided by separate covers is merged into the T-profile's horizontal top surface. This surface acts as both the cable conduit and the protective barrier against impacts and sunlight, eliminating the need for additional protective components while maintaining comprehensive cable protection.

AI summary
The invention relates to an arrangement for installing cables on outer surfaces of crane structures (1), the arrangement comprising means (9) for routing and fastening cables to said surfaces. These means consist of T profiles (9) fastened at the stem part (10) of the T profile to the outer surface (1) of the crane structure, the upper part (11) of the T profile on top of and transverse to the stem part of the T profile being at a distance from the surface of the crane and substantially parallel to this surface, whereby the T profile together with the surface of the crane provide cable conduits (12) for the cables, which are open from the sides.
