    Opis:
    This article presents research carried out using physical data from the experimental construction of an overhead crane. This article aims to determine the dynamic behaviour of the cart-pendulum system when the hoisting mechanism hits the new bumper design at the end of the girder support structure with selected speed and bumper material to the length of the wire rope. This research shows the influence of the horizontal speed of the hoisting mechanism on the bumper force during a collision with a standard buffer and its modifications. The presented model can be the basis for modelling more complex cases, and its assumed role (i.e. the ability to determine the angle of deflection of the rope during an impact) has been confirmed and is possible to use in a specific case of an overhead crane on an industrial scale. Preliminary analysis of the construction of the bumper considered reveals its positive features, aiming, among other goals, to reduce the acceleration and force acting on the crane cart in emergency situations.

    Opis:
    The article presents the research carried out on the experimental construction of a crane, where a hoist with an AC motor without a motor control system was used as an excitation signal for the girder. The purpose of the described research is to determine the relationship between the values of the dynamic surplus factor when lifting the load with the loose rope in the initial phase of lifting and the distance of the hoist from the supporting structure. The data was obtained based on the force tests in a steel wire rope and subsequent determination of the values of stresses and deflections accompanying the selected test cases for different positions of the vibration inductor using the FE method.

    Opis:
    In the article, the problem of designing and preliminary tests on experimental test bench was taken into account. Proposed test stand allows us to carry out a series of studies concerning the dynamic phenomena accompanying the lifting of the load. Presented test bench allows, among other things, measurements of data such as the acceleration of selected points of the girder and also of cargo, displacement of cargo and centre of the girder, along with measurement of stress in selected locations and the coefficient of dynamic surplus. The electronic part of the test bench was made using the PHIDGET and the Arduino platform. Owing to the full miniaturization and implementation of control and measurement systems from the application level, test stand allows testing new mechanisms for implementing control algorithms and studying the influence of control parameters on the values of dynamic coefficients characterizing the selected dynamic mechanisms. Such an approach provides the possibility, among other things, of full control of the systems using a computer, and thus an immediate analysis of the data, which is extremely important in process of verification in the phenomenological model creation of the analyzed crane mechanisms. The proposed approach enables the development of existing ones and testing new design solutions in scale (experimental) and pure software solutions (analytical).
