Modular Enclosure Transfer System Using Rotatable Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crane systems are impractical for moving pre-fabricated enclosures due to environmental factors like high voltage overhead power lines, trees, and inclement weather, and struggle with adjusting foundations to ensure level placement.
Innovation Solution
A modular enclosure transfer system utilizing rotatable rollers and coordinated self-contained hydraulic jack units, which lift and rotate the enclosure for precise placement on a pre-laid foundation without the need for cranes, allowing for level adjustments and movement around obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a crane system is used to lift and relocate the pre-fabricated enclosure, then the enclosure can be moved from the trailer to the foundation, but the system cannot operate safely near high voltage overhead power lines, trees, or in inclement weather
Solution Approach 1:
The system divides the enclosure into manageable sections that can be transferred individually using multiple smaller hydraulic jack units rather than one large crane. This segmentation allows operation in spaces where a large crane cannot fit, eliminating the conflict between safe operation and environmental adaptability
Solution Approach 2:
The patent introduces intermediate transfer elements (hydraulic jack units and slide beams) between the trailer and foundation. These intermediaries enable the enclosure to be moved in controlled increments, allowing safe operation in obstructed environments where a direct crane lift would be unsafe or impossible
2Manufacturing precision
If a crane lowers the pre-fabricated enclosure, then the enclosure can be placed on the foundation, but adjustments for out-of-level conditions become difficult due to wobbling and swinging
Solution Approach 1:
The system uses dynamically adjustable hydraulic jack units that can be independently controlled during the transfer process. This dynamic adjustment capability allows operators to compensate for foundation level variations in real-time, achieving precise placement while maintaining ease of operation through continuous adaptability
Solution Approach 2:
The system incorporates feedback mechanisms where the height and position of each hydraulic jack unit can be monitored and adjusted based on the enclosure's alignment with the foundation. This feedback loop enables precise level adjustments without the wobbling and swinging problems associated with crane operations
3Manufacturing precision
If the slide beams are lifted to exactly the same height as the trailer, then the enclosure can be properly positioned, but this becomes difficult when the trailer is not level
Solution Approach 1:
The hydraulic jack units provide dynamic height adjustment capability, allowing each support point to be independently raised or lowered to match the trailer's actual position. This eliminates the need for precise pre-positioning of slide beams, making the system easy to operate on uneven trailers while maintaining accurate enclosure positioning
Solution Approach 2:
The system changes the operational parameters by using hydraulically adjustable support heights instead of fixed-height slide beams. This parameter change allows the system to adapt to varying trailer levels, simplifying operation while achieving precise enclosure placement through controlled height adjustments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe, efficient, and precise placement of pre-fabricated enclosures on uneven or obstructed sites, avoiding damage to power lines and facilitating level foundation adjustments without the limitations of crane systems.
Implementation Method 1
A modular enclosure transfer system is provided comprising rotatable rollers, a beam system, and a system of coordinated self-contained hydraulic jack units. A system of coordinated self-contained hydraulic jack units lift a pre-fabricated metal enclosure off a semi-trailer
Implementation Method 2
rotatable rollers are connected to the pre-fabricated metal enclosure; a beam system is used to properly locate the pre-fabricated above a foundation

AI summary
A crane-free system for moving a pre-fabricated enclosure includes a beam system and a system of coordinated self-contained hydraulic jack units, which in conjunction allow a pre-fabricated enclosure to be lifted off a semi-trailer, positioned by rolling on the system of beams above a pre-laid foundation, and lowered to the foundation. Optionally, the sliding beam system may be rotated using rotatable rollers to allow the pre-fabricated enclosure to move in a rotated direction. Optionally, a centering device and hydraulic ram may be used to center the pre-fabricated enclosure on the foundation.
