Guided Lifting Hook Attachment for Overhead Support Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting hooks are difficult to manually attach to overhead support members due to their weight and the risk of detachment during attachment, posing safety hazards and requiring heavy lifting, especially in confined spaces.
Innovation Solution
A lifting hook with a permanently and pivotably attached line guiding means at the tip, allowing the hook to be easily and safely attached to a support member using a guideline, reducing the need for heavy lifting and enhancing operator safety by enabling attachment from below.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lifting hook is made strong enough to handle heavy weights, then the lifting capability is improved, but the weight of the lifting hook increases making it difficult to manually attach
Solution Approach 1:
A guideline is introduced as an intermediary tool to transfer the attachment force from the operator to the lifting hook. The guideline allows the operator to pull the heavy lifting hook into position without directly lifting it, solving the contradiction between needing a strong (heavy) hook and the ability to manually attach it.
2Productivity
If the lifting hook is attached to an overhead support member, then the lifting operation can proceed, but the risk of detachment during attachment increases causing safety hazards
Solution Approach 1:
The guideline is attached to the lifting hook before the attachment operation begins. This preliminary action ensures that the guideline is securely connected and can be used to control the hook throughout the entire attachment process, preventing accidental detachment and ensuring operator safety.
Solution Approach 2:
The guideline acts as a mediator that provides controlled tension and guidance during the attachment process. It allows the operator to maintain control over the lifting hook as it approaches and engages with the support member, reducing the risk of uncontrolled movement or detachment.
3Ease of operation
If the lifting hook is designed to be manually carried by a single operator, then the ease of operation is improved, but the ability to reach overhead support members is limited
Solution Approach 1:
The guideline serves as a mechanical intermediary that extends the operator's reach. By anchoring the guideline to a fixed point and using it to pull the lifting hook upward, the operator can attach the hook to support members at heights that would be inaccessible through direct manual lifting alone.

AI summary
A lifting hook adapted to be attached to a support member remotely and manually by an operator, where the lifting hook is carryable, where the lifting hook comprises a hook eye and a hook, where the hook comprises a body and a tip having a tip end, where the lifting hook comprises a line guiding means permanently and pivotable attached to the tip, where the line guiding means is arranged to support or hold a guideline. The lifting hook can be attached to an overhead support member in an easy and safe manner by an operator standing on the ground.
