Point-Loaded Lifting Fork for Balanced Standing Formwork Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional formwork systems are cumbersome, requiring cranes for assembly and transport, leading to inefficient use of space, increased costs, and manual labor due to complex fastening systems, especially when handling standing formwork members.
Innovation Solution
A point-loaded lifting fork with an elongate horizontal element and vertical projection, featuring a hook body and balanced attachment points, allows for quick and secure attachment to standing formwork members, enabling efficient transport and assembly without the need for complex fastening systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If formwork members are transported as small packages with a crane, then lifting capability is achieved, but transport time increases and crane capacity is reduced
Solution Approach 1:
The lifting fork combines multiple lifting points into a single integrated device that can lift multiple formwork members simultaneously. The fork structure merges the functionality of multiple straps into one unified lifting mechanism, allowing parallel transport of multiple members and significantly reducing transport time and crane usage.
2Ease of operation
If manual fastening systems are used to attach lifting straps to standing formwork members, then lifting capability is achieved, but manual labor increases and operation becomes complex
Solution Approach 1:
The invention extracts the complex manual fastening operation by providing a pre-configured lifting fork with integrated attachment mechanisms. The fork comes ready-made with attachment points and connection elements, eliminating the need for workers to manually assemble fastening systems in the field, thereby simplifying operation while reducing device complexity.
Solution Approach 2:
The lifting fork is pre-assembled with all necessary fastening components attached before reaching the work site. The attachment points, straps, and connection elements are prepared in advance during manufacturing, so that upon arrival, the device requires minimal assembly or no assembly at all, greatly simplifying the attachment process.
3Ease of operation
If formwork equipment is stored spread out over large areas, then accessibility is improved, but storage space increases and site organization deteriorates
Solution Approach 1:
The lifting fork enables multiple formwork members to be combined into a single lifting unit, allowing them to be transported and stored together rather than individually scattered across the site. This consolidation reduces the total storage area required while maintaining accessibility, as equipment can be organized in more compact, efficient arrangements.
