Adjustment Mechanism for Hoist Clamp Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoist systems for lifting aircraft pylons face difficulties in quickly and simply adjusting to accommodate changes in the center of gravity, requiring labor-intensive and time-consuming manual adjustments of belts and chains.
Innovation Solution
An adjustment mechanism comprising a clamp, clamp bar, and optional cross-bar allows for longitudinal and lateral adjustment of the clamp, enabling quick reconfiguration to accommodate varying centers of gravity without the need for additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of belts and chains is used to accommodate changes in center of gravity, then the hoist can be adjusted to different pylon configurations, but the adjustment process becomes labor-intensive and time-consuming
Solution Approach 1:
The invention transforms the static hoist structure into a dynamic adjustable system by introducing a movable clamp assembly that can be repositioned along the frame. This allows the hoist to adapt to different center of gravity positions through simple longitudinal movement of the clamp rather than complex manual adjustments of multiple belts and chains
Solution Approach 2:
The hoist frame is divided into modular sections with the clamp assembly as a separate, independently adjustable component. This segmentation allows the clamp to be moved to different positions along the frame to accommodate varying center of gravity locations without requiring adjustment of the entire hoist system
2Adaptability or versatility
If manual adjustment of belts and chains is used to accommodate changes in center of gravity, then the hoist can be adjusted to different pylon configurations, but the complexity of the adjustment process increases
Solution Approach 1:
The invention extracts the adjustment function from the complex system of multiple belts and chains and concentrates it into a single clamp assembly. This simplified mechanism can be moved along the frame to accommodate different center of gravity positions without requiring manipulation of multiple separate adjustment components
Solution Approach 2:
The clamp assembly serves multiple functions: it provides structural support, enables positional adjustment, and accommodates various pylon configurations. This multi-functional design eliminates the need for separate adjustment mechanisms for each function, reducing overall system complexity

AI summary
An adjustment mechanism for a lifting device includes a longitudinal clamp bar and a clamp slidably disposed on the clamp bar. The clamp has a clamp body and at least one clamping member movably connected to the clamp body. The at least one clamping member is operative for (1) acquiring a clamped condition when a lifting force is applied to the clamp body, wherein in the clamped condition, the at least one clamping member is engaged with the longitudinal clamp bar to prevent movement of the clamp along the clamp bar and (2) acquiring an unclamped condition when a lifting force is released from the clamp body, wherein in the unclamped condition, the clamp is free to move along the clamp bar.
