Integrated Rigging Basket Assembly for Dropped Part Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rigging baskets require handling of loose parts, which poses a risk of injury or death due to dropped items during assembly and disassembly, and existing solutions either rely on extensive training or are excessively time and labor intensive.
Innovation Solution
A rigging assembly comprising a cable with loops at both ends, a master link, and a self-locking swivel hook that allows for the creation of a basket without loose parts by attaching the hook to the master link, eliminating the need to handle individual components during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional baskets are made with multiple loose parts (steel piece, shackles, burlap), then the basket can be assembled and disassembled, but the risk of dropping loose parts increases causing serious injury or death
Solution Approach 1:
The patent combines multiple separate components (steel piece, shackles, burlap covering) into a single integrated basket assembly. The basket is constructed as one unified structure where the steel frame, burlap lining, and attachment points are permanently assembled together, eliminating loose parts that could be dropped during rigging operations.
Solution Approach 2:
The basket is designed with integrated attachment points and structural segments that are permanently connected, allowing the entire basket to be handled as one unit rather than requiring assembly of separate components. This segmentation into functional integrated units eliminates the need for loose shackles and pins.
2Productivity
If conventional baskets require assembly and disassembly of multiple loose parts, then the basket can be reused, but the assembly process becomes time-consuming and labor-intensive
Solution Approach 1:
The basket is pre-assembled in the factory with all components permanently connected, including the steel frame, burlap covering, and attachment points. This preliminary assembly eliminates the need for on-site assembly of loose parts, allowing riggers to simply attach the complete basket to the rigging system.
Solution Approach 2:
By merging all basket components into a single pre-assembled unit, the patent eliminates the time-consuming process of assembling and disassembling multiple loose parts during each use. The integrated design allows for rapid deployment and retrieval without manual assembly steps.
3Ease of operation
If riggers must handle loose parts in mid-air to assemble baskets, then the basket can be configured, but the risk of dropping parts on ground workers increases
Solution Approach 1:
The patent merges all basket components into a single handled unit, eliminating loose parts that would need to be manipulated in mid-air. The integrated basket can be confidently positioned and attached without the risk of dropping separate components on ground workers.
Solution Approach 2:
The patent extracts the hazard of loose parts from the system by permanently integrating all necessary components into the basket structure itself. The attachment points and structural elements are built-in rather than separate, removable pieces.

AI summary
A rigging assembly has no loose parts that an up-rigger may drop. The rigging assembly includes a length of steel cable terminating in a loop at each end. One loop extends through an oblong master link, while the other loop extends through a swivel hook. The ground-rigger can attach the hook of a hoist's chain to the master link on the ground. The ground-rigger can then tie the up-rigger's rope onto the master link. The up-rigger then pulls the rigging assembly and the hoist's chain up to the beam, leaving the master link and chain under the beam. Then the up-rigger grabs the hook end of the rigging basket assembly, bends it over the beam, and attaches the swivel hook end to the master link, thus creating a loop around the beam to support the hoist's chain and load, which is known in the industry as creating a basket.
