In today's world, a portal crane is used in a wide variety of areas, as it has a large number of advantages and moves without any problems. Its carrying capacity is at a high level. Depending on the specific model, it can reach three hundred tons, which is actually a decent indicator for crane equipment. The movable mechanism has a design that contains a trolley drive and the opposite type. The balancing system acts as a unifying device. The trolleys themselves are equipped with a special anti-theft system.

Portal crane is perfect for port work. It has excellent performance parameters and is considered very productive. All portal cranes, depending on the field of application, can be divided into assembly, transfer and dock cranes. Reloading structures, as a rule, have additional elements such as gripping grabs. Dock analogues deserve special attention, implying the presence of a bunker installation on the portal. Basically, these devices are used when working with bulk cargo.

Portal himselfthe crane, based on the design features, may have a certain look. In most cases, such qualities are the responsibility of the rotary support device, which has a standard mechanism with worm or gear-shaped gearboxes. Even the portals themselves, the purpose of which is to carry out the movement of the device, have a large number of divisions. First of all, they are classified according to the attachment of the support to the crossbar, therefore, articulated and rigid devices are distinguished. An important role is played by the number of connections.

Normally, a gantry crane has a rigid frame underneath that can span one or more railroad tracks. Thanks to this, unimpeded passage of rolling stock is carried out. A turntable is installed on the portal, which serves as a support for the turntable with a frame. A rocker arm is already mounted on it. The cabin is located on a turntable. Today, straight and articulated arrows are especially popular. The first of them have a minimum rope length and good rigidity. As for direct analogues, they are light in weight and have a simple design.

It is possible to maintain a portal crane in good operating condition for a long time only if we do not forget about industrial safety expertise. Their task is to periodically assess the technical condition of the crane equipment. The operating period of these devices is usually 25 years. In the economic conditions of ourtime it is impossible to change all the elements of the crane at once, therefore, restoration work should be carried out regularly. They will help to increase operational capabilities by almost two times.
