systems of movable roof segments - Opis:
- In the conceptual design of an ecological floating dock, has been assumed to be applied a roof system consisted of six movable segments whose aim is to shelter dock’s working space from environmental influence. The dock has to be also equipped with a gantry crane. Each of the devices is fitted with a traction system whose drive is the subject of this paper. The driving system consisted of synchronous electric motors with external frequency control of their rotational speed, is proposed. Such system may ensure the same rotational speed at both supports, unambiguously determined by voltage frequency and independent of load. The solution could make it possible to avoid dangerous skewing displacements of the structures on rail tracks during service. Additionally, a simplified procedure of determining the main loads necessary for calculation and selection of the devices and traction systems is also presented.
