The goal of this paper is to establish overview of utilisation of synchronous lifting in practice and the proposal for hydraulic system which provides synchronous lift of heavy load. According to type of operation it is possible to choose specific hydraulic kit. The main parameters are load capacity and lifting height. http://pubs.sciepub.com/ajme/2/7/4/ajme-2-7-4.pdf hydraulic circuits synchronous lift
