As țara mea's construcții proiecte continuă să devină scară mai mare, the weight of the required mechanical equipment will also growth, and the market demand for large-scale lifting equipment will growth semnificativ. At this time, the advantages of cauciuc tyred gantry crane (RTG) are becoming more and more evident, and the need for them is also crescând. Astăzi I voi în principal talk about the design features of tire-type cranes to see what is special about them and how they will develop in the future. .
The tire-type crane is improved on the basis of the crawler crane. When designing the tire-type crane, the lifting mechanism is installed on the bottom beam to reduce the weight of the trolley, thereby reducing the load on the main beam and providing the possibility for structural optimization. The main beam adopts normal beam, and the structural stress is clear and reasonable. The door legs adopt a variable cross-section box-shaped structure, which reduces the weight of the door legs. The inner side is a vertical plane and the outer side is an inclined plane, ensuring that the outer side is under pressure and the inner side is under tension when loading. The trolley adopts the form of plate beam, with lifting pulleys arranged on both sides, and only the trolley junction box is arranged on the upper plane, which reduces the weight of the trolley.
A management system is installed on the rubber tyred gantry crane, which can display and monitor the operating status and mechanism status of the crane in real time, display fault information and solutions in a timely manner, and provide production statistics for loading and unloading operations. Energy recovery and storage technology is applied to cranes. The energy storage device is connected in parallel to the common DC bus of the equipment. When the operating motor is in power generation mode, the energy storage device is charged. When the equipment performs energy-consuming actions, such as lifting , when the cart and trolley are running, the energy storage device is discharged. In the entire action process of the equipment, there is only conversion of mechanical energy and electrical energy, without heat energy consumption, achieving the purpose of energy saving.
