On August 14, seven large-capacity cranes including a 180-ton metallurgical bridge crane, a 90+90-ton semi-gantry crane, and a 100-ton overhead crane were shipping to Kazakhstan, serving for a steel group project.
These metallurgical cranes are designed in accordance with the FEM standard. With modular design and modern computer technology, these cranes are of highly automation, intelligence and high-tech, for the production site with a large temperature difference.
180-ton Metallurgy Crane Technical Features:
1. This crane adopts a new rigid bridge structure with four girders, four rails and double trolleys, and the working level reaches A8;
2. The self-weight is reduced by 10%, the height is reduced by 25%, and the width is reduced by 25%; the product can be applied to the ambient temperature of -40°C to +60°C;
3. The new type of festoon cable power supply device that is resistant to high temperature radiation can operate reliably under the condition of high temperature radiation.
Technical Features of 90+90 ton Semi-gantry Crane:
1. This crane is a special material charging semi-gantry crane for steel mills. The lifting capacity of the crane is 90+90t, the lifting height is 24m, and the working level is A8;
2. The product has been newly designed for the problems of limited production space, high risk factor of tilt-pulling and hoisting during feeding, and excessive wire rope tilt-pulling angle;
3. It adopts the structure of 3 girders and 4 rails, and 2 independent lifting mechanisms are designed on each trolley, equipped with a special four-point gantry hook spreader, and the two lifting mechanisms can realize the function of hopper dumping and feeding through their independent actions;
4. Finite element optimization check calculation of the overall structure, simulate the actual operating conditions of the crane, and reduce the dead weight and the wheel pressure by 10%;
