Contemporary handling operation efficiency and safety in cargo transportation realized by the cranes mainly depends on counteractions taken against undesirable phenomena’s such as payload swing. The research problem connected with anti-sway problem has been extensively researched over the past decades. Generally the proposed solutions can be classifying as an open and closed-loop control system. The close loop sway angle control system are strongly connected with necessity of physical measuring the angle of the swinging rope. The paper was focused on the non-contact method of measuring the angle of swinging payload with the image analysis technique use. However, in the statement the authors attention was focused on the issue related to the verification that infrared light illuminator can be used in built a non-contact vision sensor for the sway measure insensitiveness on actual exposure light conditions. All experiments and tests were conducted on the scaled physical model of overhead travelling crane with hosting capability of 150 kg.
