The Concept of an Energy-Efficient, Modular Hydraulic Device that Increases Work Safety and Reduces Labor Intensity in the Construction of Large-Scale Structures in Field Conditions

The thematic scope of the work includes issues of power hydraulics, energy efficiency and safety of machines as well as issues of devices for construction works of large-size structures. The project is implemented in a joint doctoral school and the PONAR Wadowice company as part of the 6th edition of the “Implementation Doctorate” program. The purpose of the work is to create an energy-saving, modular hydraulic device that increases work safety and reduces the labor intensity of the process of building large-size structures in field conditions. Paper consist the concept of implementing a new technical device. When lifting the structure, the hydraulic system maintains a constant oil flow rate with dynamic pressure changes, maintaining the synchronous movement of the actuators. After reaching a predetermined level, the device must support the entire structure so that construction workers can start the next stage of construction. The designed device, under which research is in progress, would comprehensively support construction companies and actually increase the safety of performed works. The device is powered by a diesel power generator, an important aspect of research work will be the reduction of CO2 emissions by increasing the efficiency of the device and increasing the precision of work. The advantage of the project is its complexity. Optimization of the design in terms of product life cycle, durability and ergonomics.
