Title:
HYDRAULIC SYSTEM FOR RECOVERING CONSTRUCTION MACHINE BOOM POTENTIAL ENERGY
Document Type and Number:
WIPO Patent Application WO/2023/229409
Kind Code:
A1
Abstract:
The present invention relates to a hydraulic system for recovering construction machine boom potential energy, and to a hydraulic system for recovering construction machine boom potential energy, the system recovering boom potential energy generated during boom down of a construction machine boom so as to directly apply same to boom up, thereby improving the boom up speed of a boom cylinder and, also, enabling the boom potential energy to be used for other various operations of the construction machine. According to the present invention, energy wasted during boom down can be recovered and utilized. Additionally, the system can be easily attached to or released from a conventional construction machine.
