Recently, 7 large-capacity cranes were shipping to Kazakhstan serving for a steel group project. The cranes including a 180-ton ladle bridge crane, a 90+90-ton semi-gantry crane, and a 100-ton bridge crane.

These cranes for metallurgy industry are designed with the European FEM standard. With modular design and modern computer technology, these cranes are fully automated, intelligent, suitable for the production site with a large temperature difference.

180-ton Ladle Crane Technical Features:

1. This ladle crane adopts a new rigid bridge structure with four girders, four rails and double trolleys, and the working level reaches A8;

2. The crane-weight is reduced by 10%, the height is reduced by 25%, and the width is reduced by 25%; the crane 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 semi-gantry crane is a dedicated material charging crane for steel plant. The lifting capacity of the crane is 90+90t, the lifting height is 24m, and the working level is A8;

2. The crane is a latest design 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%;
