Abstract. Problem. The article deals with the topical and modern issue of ensuring high reliability and increasing the productivity of machines equipped with a hydraulic drive. A promising direction is to increase the efficiency of machines by developing a system of thermal control of the working fluid. The design of hydraulic drives requires innovations in the design of hydraulic tanks and their location in the machine. It is necessary to take into account the existing experience of designing and operating similarly designed hydrofueled machines. As a result, it is planned to develop a system of measures that increases the efficiency of the hydrofied machine. Goal. The goal is the development of the method of road marking and automatic control of road traffic using multifunctional road panels. Methodology. The aim is to develop a method of heating the hydraulic fluid of the actuator. Results. The principle of operation of the working fluid heating system is described. The expected results of the work are a system of measures that will significantly increase the reliability of the hydraulic drive and the efficiency of the entire hydrofied machine. Originality. The effectiveness of the hydraulic actuator itself is ensured by high-quality design, manufacture, and operation. The work is aimed at using the developed equipment in the hydraulic drive to stabilise the parameters of the working fluid, which must be maintained throughout the operation of the construction machine. Practical value. As a result, it is planned to develop a system of measures to improve the efficiency of the hydrofiltration machine.
