Improving energy utilization in hydraulic booms has been an important scheme for industries and designers due to energy cost, environmental requirements, etc. This paper presents accumulator-charged drive in a Loglift boom, which is driven by Electro-hydraulic Load-Sensing (ELS) system based a micro-controller. The practical measurement and simulation are carried out for different work situations. The energy transfer process for a typical duty cycle is calculated and compared. The experimental and theoretical results show that this drive can improve energy utilization. The validation of its experiment in an example hydraulic boom will encourage its further research for possible application.
