Excavator-Mounted Cable Winding With a Collapsible Power Reel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable pulling apparatuses face limitations in efficiency, power, torque, and mobility, particularly when used in remote or undeveloped job sites, and often require lengthy setup and breakdown times, limiting their effectiveness in construction applications.
Innovation Solution
A cable pulling apparatus designed for attachment to an excavator, featuring a motor positioned opposite the power reel spool for balance, a collapsible power reel with radially expanding and contracting segments, and a quick connect mechanism for easy attachment and detachment, enhancing power, torque, and reducing setup time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the motor is positioned inside the housing near the power reel spool, then the structure is more compact, but the apparatus becomes unbalanced and less efficient
Solution Approach 1:
The motor is repositioned from an internal location to an external location on the opposite side of the housing, utilizing spatial dimensionality to achieve balance. This external positioning on the opposite side creates a balanced distribution of mass that improves operational stability while maintaining a relatively compact overall structure.
2Adaptability or versatility
If the cable puller is transported to remote job sites, then mobility is improved, but setup and breakdown time increases
Solution Approach 1:
The cable pulling apparatus is divided into separable components including the housing with motor, the power reel spool, and the bucket attachment. This segmentation allows the apparatus to be quickly assembled and disassembled at remote job sites, reducing setup and breakdown time while maintaining mobility and adaptability to different locations.
3Power
If greater power and torque are provided by the cable puller, then pulling speed and capability increase, but the apparatus becomes more complex and heavier
Solution Approach 1:
The cable pulling apparatus merges the motor, housing, power reel spool, and bucket attachment into an integrated system. This combination allows the apparatus to deliver greater power and torque for enhanced pulling capability while avoiding the complexity of separate interconnected components, as the motor directly drives the spool within the unified housing structure.

AI summary
A cable winding apparatus mounted on an arm of an excavator. The cable winding apparatus comprises a housing, a hydraulic motor disposed within the housing where a portion of the hydraulic motor extends through the second wall of the housing, a drive shaft extending through the housing that is connected to the motor, and a collapsible power reel. The collapsible power reel comprises a plurality of segments movably coupled to the collapsible power reel and extending radially from the collapsible power reel. The plurality of segments can engage a cable and enable the cable to be wound around the collapsible power reel as the hydraulic motor rotates the collapsible power reel. The plurality of segments are configured to collapse in an axial direction, thereby enabling the wound cable to be easily removed from the apparatus.
