Case:

1. Project Name: Ethiopian Commercial Bank Headquarters Building Project

Project Overview: The total height of the project is 206m (excluding underground engineering), and each floor of the building has an angle change, with a beautiful and complex appearance. Construction elevator configuration requirements for the main building: frequency conversion speed control elevator, lifting speed 0-56m/min, rated load capacity not less than 2T, cage size not less than 3.8 * 1.5 * 2.5, maximum lifting height not less than 206m

Number of elevators used: 4, specifications: SC200/200

Main engineering challenges solved:

1. The surface of the building presents irregular changes, with beautiful shapes and complex structures;

2. The project has a high height and requires high operating speed;

3. The foundations of the two construction elevators need to be arranged on the bottom foundation of the podium building, without affecting the engineering foundation, and the positioning should be accurate;

4. Multiple sizes and structures of attachment devices are combined.

III. Project Name: Fertilizer Plant High Tower Granulation Project

Project Overview: The total height of the project is 108m, and the building surface is conical. The continuous working time of the elevator is extremely long. After starting up, the elevator needs to run continuously for more than 3000 hours, with a load of 1.8 to 2.0 tons per operation. When the cage is running, there is no one controlling it inside.

Number of elevators used: 2, specifications: SC200/200

Main engineering challenges solved:

1. The surface of the building is circular, and the influence of wind is significant;

2. Running at full capacity, with prolonged continuous operation time;

3. When the cage is in operation, there is no one controlling it inside;

4. The air environment around the fertilizer plant is harsh, and it is highly corrosive to the equipment.
