Rotating Boom Cable Puller for Tight Conduit Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable pullers lack sufficient flexibility to navigate through small spaces and access conduits at various heights, limiting their effectiveness in certain applications.
Innovation Solution
The cable puller design includes a boom assembly with rotatable arms and a strike plate, allowing for improved rotational features that enable the longitudinal axes of arms to align parallel, facilitating easier deployment and positioning within tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cable pullers are designed with fixed rigid structures, then structural strength is maintained, but flexibility to navigate small spaces and access conduits at various heights is reduced
Solution Approach 1:
The cable puller is divided into multiple modular components including a frame, boom assembly, conduit engagement device, and capstan assembly that can be independently positioned and oriented. This segmentation allows each component to be optimized for its specific function while collectively providing the needed flexibility to navigate complex spatial configurations and access conduits at various heights
Solution Approach 2:
The cable puller incorporates dynamic positioning capabilities through rotatable boom assemblies and adjustable conduit engagement devices that can pivot and rotate to different orientations. These dynamic features enable the device to adapt to varying conduit locations and angles, providing the flexibility needed to access conduits at different heights and navigate through confined spaces
2Ease of operation
If cable pullers are designed with simplified structures, then ease of operation is improved, but capability to access conduits at different heights and navigate tight spaces is reduced
Solution Approach 1:
The cable puller is equipped with pre-configured boom assemblies and conduit engagement devices that are positioned and oriented before operation begins. This preliminary configuration allows the device to be quickly deployed into the desired spatial arrangement, simplifying the operation while maintaining the capability to access conduits at various heights and navigate tight spaces

AI summary
Cable pullers are provided. A cable puller includes a frame, and a boom assembly rotatably connected to the frame. The boom assembly includes a drive assembly, a first arm extending in a first direction from the drive assembly, a second arm extending in a second opposite direction from the drive assembly, and a third arm rotatably connected to the second arm. Rotation of the boom assembly relative to the frame causes rotation of the third arm relative to the second arm to a position wherein a longitudinal axis of the third arm is parallel with a longitudinal axis of the second arm.
