Abstract
Abstract This article deals with the problem of the effective use of car jacks for passenger cars. The aim of the study is to create a theoretical basis for improving the efficiency and safety of the application of car jacks in car service enterprises. Based on the analysis of the review of existing designs, which are used in the technological process of car service, the universal classification of the car jack is modernized. As a result of the study, a comparison of technical indicators of the types of car jacks used in car service centers in Kazakhstan has been carried out. We propose an optimal range of load capacity. The results of the work, when implemented in the practice of design, will provide a reasonable reduction in the present costs of equipping the lifting equipment in car service stations and the operation of car jacks at the expense of more advanced methods of calculation and design.
