AI Technical Summary

Benefits of technology

In this technology for recycling or regenerating energy from an elevator machine it uses two types of motors - one works with constant speed while another tries to match its own speeds by adjusting certain parameters like voltage levels during operation. By controlling these variables, the machines are able to convert their kinetic energy back into electricity efficiently without adding extra parts.

Problems solved by technology

This technical problem addressed in this patents relates to improving the efficiency and effectiveness of construction machines that use hoist-lifting mechanisms like lifting platforms (also called scaffolders) used at building sites. These machine tools have heavy loads due to their own gravity while being lifted up from high points on buildings where they may fall over accidentally causing damage. To address these issues, various methods were developed including regenerative braking systems and hydrostatic power recovery systems. However, existing solutions involve adding extra components to achieve better performance compared to traditional ways.
