Reparability and labour intensity comparison for trolleybuses and buses maintenance and repair operations

Abstract

Introduction . Trolleybuses and buses are the main type of railless public transport. This article examines the factors affecting the cost of transportation, in terms of maintenance and repair of rolling stock in detail. The main purpose of this study is to compare the values of labour intensity for maintenance and repair of trolleybuses and buses and to identify the reasons that affect the difference in the values of labour intensity for maintenance and repair of trolleybuses and buses. Materials and methods . To achieve this goal, the following tasks were solved: 1. The analysis of operating manuals, maintenance and repair instructions, valid during the corresponding periods of operation, for trolleybuses (ZIU-9, BKM-321, PKTS 6281) and buses (LiAZ-677, MAZ-103, MAZ-203) was carried out. The analysis and comparison were made for vehicles of three conditional generations: the 1970s - 1990s, 2000s and 2010s. 2. The reasons influencing the difference in the values of labour intensity of maintenance and repair of buses and trolleybuses are determined. 3. Proposals to amend Order No. 351 of the Ministry of Transport of the Russian Federation have been formulated. Discussion and conclusion . The comparison of the values of the labour intensity of the selected vehicles was made. The recommendations on changing the labor intensity values for maintenance and repair of trolleybuses in comparison with buses, established by Order of the Ministry of Transport of the Russian Federation No. 351, when calculating the initial minimum price of the contract for passenger service by trolleybuses and buses are given. Originality . The comparison of the complexity of performing maintenance and repair operations of trolleybuses and buses in the context of types of equipment and for vehicles of different technical generations is made.
