\"cranes\"<\/a>An overhead crane as a type of UTB is used to move heavy loads. In simplest terms, it is used to lower and raise goods vertically or horizontally via a hoist or winch. They are characterised by their simple design. They are most commonly used in industries such as transport, manufacturing or construction. When it comes to the design of an overhead crane, it is important that it has adequate strength and fatigue life. The idea is to ensure safe operation of the machine, which can be disrupted by static and dynamic loads.<\/p>\n

Overhead cranes are used in ports, warehouses and also in transport companies. The use of cranes makes it easier and quicker to carry out work. Girders are a part of the load-bearing structure used singly or in pairs, and are usually made in the form of a welded box structure. It is possible to distinguish between a girder whose ends are supported on cranes perpendicular to them, equipped with castors. The trusses, together with the girder, are made of steel of adequate strength. The connection between the cranes and girders enables the longitudinal movement of the crane bridge relative to the substructure.<\/p>\n

The winch\/ hoist\/ winch system is responsible for performing the vertical lifting movement. The most important traction systems are steel cables or chains. Overhead travelling cranes with rigidly guided hoists are also common. The mechanisms for implementing the travel movement are based on working in two mutually perpendicular directions. . This creates the conditions for the working space. As far as the electrical installation is concerned, the most common methods used are cable ducts (cable curtains) and cable guides. Cable curtains are flexible cables mounted on cable trolleys, which form a system mainly for powering a hoist or winch. In contrast, the most common for gantry cranes are cable curtains, which are fed to devices suspended from the crane hook, such as an electromagnet.<\/p>\n
