  - Rok 2019

  The paper presents a numerical analysis of steel brackets supporting a double-span crane runway girders. The purpose of the study was to assess the new structural solution based on the stress distribution in the brackets. In order to simplify the connection, the bottom flange of the crane runway girder is based directly on the upper flange of the bracket. As a result, the support reaction is no longer applied in the plane of the...

  - Polish Maritime Research - Rok 2016

  As the devices designed to transport materials, the overhead cranes should meet certain geometric requirements for their operation to be safe. The presently available geodetic equipment, in particular total stations, provides opportunities for precise 3D measurements of coordinates of the controlled points. These coordinates make a basis for correcting the height of crane runway axes. The paper presents a method to calculate position...

• Gender and support Polish women at the beginning of their professional career in IT

  Publikacja

  • A. Wałachowska

  - Rok 2021

  The development of ICT should be understood not only as an increase in the number of users skilled in the use of new technologies, but also as an ever-increasing demand for qualified professionals capable of creating, administering, supporting, and servicing ICT systems. With regard to the continuous development of innovative technologies, there is a noticeably low share of women who actively create and co-create this sector,...

  Immobilizowane membrany ciekłe stały się przedmiotem intensywnych badań w ostanich latach, głównie w procesach oczyszczania strumieni gazowych. Kluczowym czynnikiem mającym wpływ na efektywność tych procesów ma czas życia układu membranowego, a zatem odpowiedni dobór nośnika i fazy membranowej. W porównaniu do nośników polimerowych, ceramiczne charakteryzują się większą grubością, jednak są bardziej stabilne termicznie. Praca...

  • B. Banach
  • R. Piotrowski

  - Rok 2017

  From the control viewpoint, 3D crane is a dynamic, nonlinear and multidimensional electromechanical system. In this paper, five control systems using a set-point weighted PID controllers (modified controllers) are designed. These structures and properties are presented. Optimization process of controllers settings based on integral performance indices is made. Simulation tests of control systems are presented. Comparison of integral...

• New Method for Determination of Adjustment Corrections for Crane Rail Axes

  Publikacja

  • W. Kamiński

  - REPORTS ON GEODESY AND GEOINFORMATICS - Rok 2013

  Electronic tacheometers are currently a standard instrument used in geodetic work, including also geodetic engineering measurements. One of the many applications of tacheometers in engineering geodesy are 3D control measurements of crane rail axes. This paper proposes a new method of computing adjustment corrections for crane rail axes based on 3D polar measurements performed with an electronic tacheometer. The intermediary method...

  • W. Kamiński
  • K. Makowska-Jarosik

  - Geosciences - Rok 2019

  Safety is one of the key aspects related to crane-based material transport. In order to ensure safe crane operation and material transport, it is necessary to meet certain geometrical conditions. The authors addressed the geometrical conditions of a crane bridge, a substantial crane component. The paper presents the method to compute displacement components of points on the top of a bridge crane relative to their design position....
