The paper contains an analysis of brake system designs pertaining to loaders of international manufacturers. Tendencies in their development modernization of road-construction machinery as whole have been revealed in the paper.

Main criteria on general structure formation of a traction drive gear have been systemized and rated on the basis of the analysis in respect of the requirements made to trolleybuses by normative and technical documents and also peculiar features and tendencies in the world trolleybus manufacturing process.

The paper analyzes factors that determine dynamic loads of mechanical transmission of trolleybus traction driving gear. The paper proposes a methodology for determination of calculative moments of loading transmission elements. Results of the research are analyzed and recommendations on dynamic reduction of trolleybus transmission are given in the paper.

Schemes and operational principles of antislippage and antiblocking trolley bus systems improving efficiency and safety of acceleration and bralang processes are described in the paper.
