Adjustable Cable Anchoring Assembly for Heavy Monopole Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anchoring systems for cables on monopoles, guyed antenna towers, and cable ladders are inadequate in supporting heavier cables, leading to capacity issues and damage to accessories due to the lack of a universal anchor device that can simultaneously lift and support both internal and external cables.
Innovation Solution
An anchoring system comprising a base module with clamping members and an expansion module, featuring adjustable threaded members and eyebolts to securely engage monopoles, guyed antenna towers, and cable ladders, allowing for flexible installation and increased load-bearing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If current anchors (e.g., J-bolt anchors) are used to secure cables to monopoles, then installation is simple, but the anchors fail when cable weight exceeds their capacity
Solution Approach 1:
The anchoring system is divided into multiple clamping members (typically three) that collectively distribute the cable load. Each clamping member independently engages the monopole, and their combined strength exceeds the capacity of single traditional anchors, allowing the system to handle heavier cables while maintaining manageable individual component complexity
Solution Approach 2:
Multiple clamping members are merged into a single integrated anchoring assembly that functions as one unified support structure. This combination allows the system to achieve higher load-bearing capacity through collective strength while providing a standardized installation process similar to traditional anchors
2Adaptability or versatility
If a universal anchor device is designed to simultaneously lift and support both internal and external cables, then cable support capability improves, but device complexity increases
Solution Approach 1:
The anchoring system is designed with multiple eyebolts extending in different directions, enabling a single device to simultaneously support internal cables routed through the monopole and external cables attached to the exterior. This multi-functional design eliminates the need for separate anchoring solutions for different cable routing configurations
Solution Approach 2:
The system accommodates both internal and external cable routing configurations within a single anchoring structure. Internal cables can be routed through the monopole and attached to eyebolts, while external cables attach to other eyebolts on the same assembly, creating a nested arrangement where multiple cable management functions coexist in one device
3Strength
If accessories are improperly used to support heavier cables, then cable support is achieved, but damage occurs to the accessories
Solution Approach 1:
The anchoring system uses threaded members with adjustable pitch and clamping member geometry optimized for heavy cable loads. The threaded connectors provide controlled mechanical advantage for tightening, and the clamping members are dimensioned with appropriate wall thickness and material properties to withstand the stresses of heavy cable support without deforming or failing

AI summary
The present application is directed anchoring systems for cables on a monopole. An anchoring system includes a base module having a plurality of clamping members. Each clamping member includes an upper plate having a plurality of apertures, a lower plate coupled to the upper plate by two or more support beams, each support beam having an aperture configured to receive a threaded member, and a hollow pipe secured between the upper and lower plates. An eyebolt is received through the hollow pipe and secured to the clamping member. Adjacent clamping members are connected by the threaded members that engage with mating threaded connectors to allow for decreased or increased spacing between the clamping members to engage the monopole therebetween, and each eyebolt is configured to engage one or more hoisting grips that support cables being routed inside and/or outside of the monopole. Alternative anchoring systems are also described.
