AI Technical Summary

Benefits of technology

This patented technology describes two technical features - including ease of handling and installation, accuracy in aligning underground parts (such as tubular bushes), reduction in stress risks during maintenance tasks or replacing damaged components without requiring human interventions. Additionally, this design allows for easy rotation/displacements while maintaining accurate placement over long distances. Overall, these technologies help reduce costs associated with managing large numbers of buried assets such as pipelines.

Problems solved by technology

Technological Problem: Current methods for maintaining watermilage in an old type of machine require manual removal or use tools that may be damaging during alignment processes. Additionally, there're technical problem addressed by these inventions which involve difficulty removing heavy equipment from older machines without causing them to break down overtime.
