Generator Canopy Lifting System with Removable Spanning Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canopy designs for machines like generator sets require separate production for single and double-point lifting systems, limiting flexibility and increasing costs due to the need for additional structural strength in single-point systems.
Innovation Solution
A canopy with a pair of opposed upright lifting frame members and a removable spanning member that can be connected between them, allowing conversion between two-point and single-point lifting systems, enabling a single canopy to serve multiple configurations without external modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single-point lifting system is provided, then lifting capability is improved, but manufacturing cost increases due to additional structural strength requirements
Solution Approach 1:
The lifting system is segmented into a permanent two-point lifting configuration and a removable single-point spanning member. The spanning member can be added or removed based on lifting requirements, allowing the base structure to maintain simpler two-point lifting strength while providing single-point capability when needed through the附加 spanning member.
Solution Approach 2:
The lifting system transitions from a static single-point design to a dynamic configuration where the spanning member can be removed. This allows the structure to adapt between single-point and two-point lifting modes, providing single-point strength only when required rather than permanently, thus reducing overall manufacturing cost.
2Adaptability or versatility
If separate canopies are produced for single and double-point lifting systems, then lifting requirements are met, but device complexity increases
Solution Approach 1:
A single canopy design serves multiple lifting functions by incorporating both permanent upright lifting frame members for two-point lifting and a removable spanning member that enables single-point lifting. This universal design eliminates the need for separate canopy variants while maintaining both lifting capabilities.
Solution Approach 2:
The lifting configuration dynamically changes based on the presence or removal of the spanning member. The same physical canopy structure adapts between single-point and two-point lifting modes, providing versatility without requiring multiple static canopy designs.
3Stability of the object's composition
If lifting eyes are provided in a recess, then stacking capability is improved, but access for modification becomes more difficult
Solution Approach 1:
The spanning member and single-point lifting eye are extracted as a separate removable component rather than being permanently integrated into the recess. This allows the recess to maintain its stacking function while the removable spanning member can be easily accessed through canopy openings for installation or removal without compromising stacking capability.

AI summary
A canopy for a machine such as a generator set has a pair of upright lifting strops (10) for attaching to a pair of lifting eyes. The canopy also has a removable spanning member (18) connectable between the strops for attachment to a single lifting eye (23). Thus the canopy can be adapted for single or double point lifting depending upon customer requirement.
