Weihua made 7 large-capacity gantry cranes and bridge cranes for a project in a Kazakhstan steel plant, which including a 180-ton bridge crane, a 90+90-ton semi-gantry crane, and a 100-ton bridge crane.

These metallurgical gantry cranes and bridge cranes are farbricated with the FEM standard. They are designed with modular structure and modern computer technology, so the feaures of highly automation, intelligence and high-tech are suitable for the production site with a large temperature difference.

180-ton Bridge Crane 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.

90+90 ton Semi-gantry Crane Features:

1. This semi-gantry crane is a special material charging 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. This crane 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%;
