Tractor Boom Apparatus for Lifting Heavy Detachable Implements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently lifting and transporting large and heavy detachable implements, such as dozer blades or stump splitters, from prime movers like crawler tractors to remote storage or job sites, as existing methods are cumbersome and labor-intensive due to the substantial size and weight of these implements.
Innovation Solution
A boom apparatus is mounted on the prime mover, comprising a base section and extendable sections that can be telescopically extended to connect with the detached implement, allowing the push frame to pivot upward, lifting and lowering the implement for placement on a truck bed, with hydraulic actuation for ease of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detachable implements are removed from the job site using conventional methods (loading onto truck bodies), then the implements can be transported to remote storage or another job site, but the substantial size and weight of the implements make it difficult and labor-intensive to lift and place them on truck bodies
Solution Approach 1:
The patent introduces a boom apparatus as an intermediary lifting device between the ground and the truck body. The boom includes a base section pivotally connected to the prime mover and an extendable section that can be telescopically extended to reach the implement on the ground, providing mechanical advantage to lift heavy implements without direct manual handling
Solution Approach 2:
The boom apparatus employs dynamic extendable sections that can be telescopically extended and retracted. When lifting an implement, the extendable section extends to reach the implement on the ground and provides the necessary lifting height. The push frame pivots upward to lift the implement, and the boom's extendable sections adjust dynamically during the lifting operation
2Adaptability or versatility
If the boom is extended to reach detached implements on the ground, then lifting capability is achieved, but the apparatus becomes more complex
Solution Approach 1:
The boom is divided into multiple sections: a base section pivotally connected to the prime mover and extendable sections that can be telescopically extended. This segmentation allows the boom to achieve extended reach and lifting capability while maintaining a compact stowed configuration. The push frame is also segmented with side sections and a transverse section that can pivot independently
Solution Approach 2:
The extendable sections of the boom are telescopically connected, allowing one section to be nested within another when not in use. This nesting principle reduces the overall complexity and stowed size of the apparatus while maintaining the capability to extend to the necessary length for lifting implements from the ground
