Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Tyrolean traverse systems are complex and costly to manufacture, necessitating a simpler and more cost-effective apparatus for moving loads between remote locations.
Innovation Solution
A trolley system comprising first and second spaced plates with fixed and removable sheave components, allowing for the connection and disconnection of lines to facilitate movement along a main line, featuring quick-release securing pins and pulley assemblies for efficient load transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Tyrolean traverse systems are used, then reliable load movement is achieved, but manufacturing cost and complexity increase
Solution Approach 1:
The trolley is divided into modular components: fixed sheaves permanently mounted between plates, and removable sheave components that can be attached or detached as needed. This segmentation allows the system to maintain reliability through proper load distribution while reducing overall complexity by allowing selective use of sheave components
Solution Approach 2:
The sheave components are designed to be dynamically configurable - they can be removed from the plates when not needed, allowing the system to adapt its complexity level. The quick-release mechanism enables rapid reconfiguration, maintaining reliability only when the dynamic configuration is properly set up
2Reliability
If traditional Tyrolean traverse systems are used, then reliable load movement is achieved, but manufacturing cost increases
Solution Approach 1:
By segmenting the sheave system into fixed and removable components, the patent reduces manufacturing costs. The fixed sheaves provide essential functionality, while removable sheave components are only manufactured and installed when specific load requirements demand them, avoiding unnecessary manufacturing expenses for complete traditional systems
Solution Approach 2:
The trolley design with multiple fixed and removable sheaves creates a universal system that can handle various load types and configurations. This multi-functionality reduces the need for multiple specialized devices, thereby lowering overall manufacturing costs while maintaining reliability across different applications
3Reliability
If removable sheave components are connected to plates, then line retention is improved, but assembly complexity increases
Solution Approach 1:
A quick-release securing pin acts as an intermediary mechanism between the removable sheave component and the plates. This simple intermediary device provides reliable line retention when engaged, while allowing rapid assembly and disengagement, thereby managing assembly complexity through a straightforward coupling mechanism rather than complex fastening systems

AI summary
A trolley for lifting and/or moving a load on one or more lines is disclosed. The trolley comprises: a. first and second spaced plates (10, 12), b. at least two fixed sheaves (30) that are disposed for rotation about respective parallel axes between the first and second plates (10, 12), and c. a removable sheave component (48). The removable sheave component (48) is, while in use, disposed for rotation about an axis parallel to that of the fixed sheaves between or adjacent to the first and second plates (10, 12). The removable sheave components is, while in use, carried on a shaft (24) that is connected to the plates, which connection is capable of being disconnected to permit removal of the removable sheave components from connection with the plates. Also disclosed is an installation for lifting and/or moving a load that includes such a trolley and a method of installing such an installation.
