Reversible Edge Protector for Lifting Slings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial slings, particularly synthetic ones, are prone to damage from abrasive or sharp edges of heavy loads during lifting, leading to increased wear and potential damage to both the sling and the load, with existing protectors not effectively addressing these issues for lifting equipment.
Innovation Solution
A reversible edge protector with Velcro attachment straps and a body portion that forms a tunnel around sharp edges, using spacers to distribute the force over a larger surface area, protecting both the sling and the load from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic slings are used to lift heavy loads, then the slings provide flexibility and protection from elements, but the outer cover is vulnerable to damage from abrasive or sharp edges
Solution Approach 1:
The patent introduces an edge protector as an intermediary component between the synthetic sling and the load with sharp edges. This protector distributes the contact force over a larger surface area, preventing the concentrated stress that would otherwise damage the sling's outer cover while allowing the sling to maintain its synthetic material advantages.
2Object-affected harmful factors
If metal slings are used to lift abrasive or sharp-edged loads, then the slings are resistant to damage, but they lack the flexibility and protective qualities of synthetic slings
Solution Approach 1:
The patent combines the advantages of both metal and synthetic slings by using a synthetic sling for flexibility and element protection, while adding a metal or metal-reinforced edge protector to provide the abrasive and sharp edge resistance characteristic of metal slings.
3Adaptability or versatility
If eye bolts are attached to objects for lifting, then the slings can accommodate unwieldy objects, but the process increases time and cost
Solution Approach 1:
The patent extracts the edge protection function from a permanent attachment system (eye bolts) and creates a separate, reusable edge protector that can be quickly applied and removed without modifying the load object, thereby eliminating the time-consuming eye bolt attachment and removal process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The edge protector effectively prevents damage to industrial slings and loads by distributing the force over a larger surface area, extending the operational life of the sling and ensuring safe lifting operations.
