Lifting equipment is primary tool in all harbors and high bay warehouses. Leading harbours in Poland like Port of Gdańsk or Port of Gdynia with Gdynia and Gdańsk shipyards and big storages in main part of country are usingmany equipments allowed to use by polish law. First of all are cranes. In everyday practise we have a few common types: overhead, mobile and fixed. First one is mostly used inside warehouses. It can be remotely controlled by worker with permission.
It is equipped in a beam on which hook-and-line device is moving. Second is mobile crane. By definition, it might change workplace so it is mostly using outside. Last one is called fixed. They are the highest and can lift the heaviest goods. It is exploit outside because of its amount. Second type of lifting equipment is gantry crane. Generally used in harbours and railway terminal to storing and stowing goods. First one was made of raw materials by Germans and placed in Danzig (nowadays it is polish city named Gdańsk) and it was built-it inside city walls. Now gantry cranes are ordinaly set with clear space inside. Because of that they are named portal cranes.
Without this devices loading and stowing huge tank ships can be really time-consuming and expensive. Investing in new science achievements shall be the prime element in budgets of logistics companies, warehouses and ports.
