The main purpose of this article is to present a possible description of kinematic characteristics concerning the direction of travel of a selected mobile working machine in motion, namely, a hinged loader. This description is presented in the form of equations, which define the circumferential velocity as well as the angular velocity of the vehicle wheels during a ride involving a curve. In this way, it is also possible to describe a function of the axle differential.

In this paper, special transport-handling equipment is presented for the purpose of pushing wagons in a trans-shipment facility. During operations, the rotary tilter device, which is an integrated part of the trans-shipment process, leads to excessive wear of the steel wire rope used for pushing wagons by means of a pusher system. Therefore, the main task was to propose a suitable design modification of the given pusher system in order to eliminate excessive wear of the rope and, in turn, to prolong operational durability for this steel wire rope, as well as for the whole technical system.
