ABSTRACT
This article presents independent tests results focused on the geometry impact of progressive gear used in a short distance transportation devices on the braking distance length both under changeable operating conditions as well as changeable loading. Variable operating conditions were obtained with the use of various lubricating agents. Five types of gears such as ASG100, PP16, PR2000, KB160 and a new solution CHP2000 were used for the tests. The tests were conducted with a free fall method application. The method gave a chance to evaluate reliability of tested gears systems and to compare the existing solutions with the proposed gear of CHP2000 type.
