Osnovni principi projektovanja velikih kontejnerskih dizalica, Deo 1 - mašinski projekat kolica i uticaj na okolinu

Abstract

Efektivna kontejnerska dizalica mora da bude projektovana tako da bude podesna za trenutne i buduće potrebe krajnjeg korisnika. Mašinske komponente moraju da zadovolje propise u standardima za mosne dizalice, ali su velike obalske kontejnerske dizalice suštinski različite u odnosu na druge tipove lučkih dizalica. Izbor dizaličnih kolica je značajan sa aspekta usvajanja i proračuna noseće strukture, točkova, i održavanja. Mehanizmi na kolicima mogu biti pogonjeni užadima (RTT), ili sa autonomnim pogonima (MOT). Hibridno među-rešenje prihvaćeno je od pojedinih proizvođača. U radu se razmatra upoređenje mašinskih sistema kolica, uključujući njihove performanse, i daje se evaluacija u procesu izbora konstrukcionog rešenja. U radu se analizira i smanjenje uticaja (buke) kontejnerskih dizalica na okolinu.

An effective container crane must be designed to suit the present and future needs of the end user. The mechanical components complied with overhead bridge crane standards, but large quayside container cranes are significantly different from other types of dockside and bridge cranes. The selection of a crane's trolley system type is significant for the structure of crane, for wheel loads, and for maintenance considerations. The trolley can be rope towed (RTT) or machinery type (MOT). A hybrid of the two systems, commonly known as a fleet-through machinery trolley (or semi-rope trolley), was adopted by some manufacturers. The paper discusses a comparison of mechanical systems of trolleys, including their performances, and gives the evaluation of selection process in design. Also, the paper analyses the ways of reducing the environmental impact - noise of container cranes on neighboring communities.
