Abstract: The article considers the possibilities of increasing the efficiency of closed kinematic loops in the mechanisms of mining, construction, and lifting-and-conveying machines. Currently, machines and mechanisms with closed kin-ematic loop do not use its properties effectively enough due to the lack of systematisation of the design and typical methods of calculating the parameters of loop closure. The authors present a variety of mechanisms with closed kinematic loops and consider the possibilities of their application taking into account different loading forces depending on the application. The authors present varieties of mechanisms with a closed kinematic circuit and consider the possibilities of their application taking into account different loading forces depending on the application sphere. We analysed the designs of the main types of loaders of kinematic loops, which provide stress in the loop. The paper presents the results of experimental studies of application of the closed kinematic loop in a laboratory bench for wire cutting. It confirmed the effectiveness of its application and allowed us to determine the rational prestressing force values for cutting various materials. Thus, the application of the closed kinematic loop with the possibility to regulate the loading force depending on the operating conditions makes it possible to improve the quality of technological processes, reduce energy consumption, improve the performance and characteristics of construction, lifting-and-conveying, and mining machines.

Key words: closed kinematic chain closed kinematic loop prestressing of the circuit loader
