The System of Tractors Operation in the Aspect of Services Provided by an Authorised Service Station

This article presents problems connected with the system of operation of agricultural tractors. The aim of this article was to determine the level of reliability of used agricultural vehicles in the aspect of needs for technical services in the authorized service station. The quantitative structure of 6127 repairs carried out by an authorized service regarding 1731 tractor pieces sold to users by a distribution company has been described in a monthly arrangement. The analysis encompasses the arrangement of the number of technical services in a percentage array in the years 2003-2014. The data analysis shows that the trend line determined for post-warranty services has varied over a span of the analysed period. The analysed services had a large amplitude of random fluctuations. The acquired seasonal indexes values prove the cyclical changes of demand for servicing in subsequent months. The tendency in the behaviour of the users who own modern agricultural tractors, to more and more common use of authorised services when it comes to carrying out technical services of the operated equipment was confirmed

Comprehensive analysis of oversized cargo transportation market in Poland (2001-2022): Trends, regulations, and industry dynamics

The oversized cargo transportation market in Poland actively participates in developing the economy, providing services necessary for implementing large infrastructure and industrial projects on a national and European scale. Development and functioning of this sector in the EU and globally requires overcoming many organisational, technical and administrative barriers and difficulties, and the authors of several publications indicate how these services are developing. The current study contains a detailed analysis of data from 2001-2022. The paper characterises the changes in particular years, indicating the main causes of the occurring processes, and defines the existing trends. It presents the legal framework that regulates the functioning of the domestic market. Moreover, it discusses the number of permits and the value of fees for issuing permits collected by the General Directorate for National Roads and Motorways (Generalna Dyrekcja Dróg Krajowych i Autostrad, GDDKiA) over two decades. The article also evaluates trends concerning the number of licenses more than 50% decrease compared to the maximum in 2008. It assesses the course of changes in values, which in 2021 reached their highest level during the period under assessment. Furthermore, it discusses the differences that occurred in the number of permits issued and applications submitted in the years 2014-2022. It describes the structure of the number of permits issued in categories IV-VII in 2014-2020 and categories III-V in 2021-2022. It characterises the course of the largest operation in the history of Polish road haulage - the transport of an abnormally-sized TBM (Tunnel Boring Machine) - in terms of requirements and problems that occurred during the preparation and fulfilment of this order and were typical for the functioning of the sector. The evaluation provides the basis for summaries and conclusions on the Development and condition of the oversized cargo transportation sector in Polish road transport sector
