HYDROSTATIC SYSTEMS FOR ENERGY RECUPERATION IN EARTHMOVING MACHINES

The first part of the paper contains the results of a study into the change in the energy parameters of earthmoving machines during manipulation tasks. The results of the research show that during certain operations of manipulation tasks, in the stop phase, the required energy of the machines has negative values. Modern earthmoving machines have hydrostatic drive systems that accumulate potential negative energy by recuperation and, if necessary, return it to the drive system of the machine for use in other operations of a manipulation task. In the second part of the paper, the analysis of the concepts of hydrostatic drive systems of earthmoving machines that enable energy recuperation is performed in detail
