Depending on the inclination, the conveyor bridges are mounted perpendicular to the benches of the open pit. An inclination of up to 40 degrees is possible and a service cab driven by a rope winch is provided for maintenance and inspection along the structure. The Chevron-MegaPipe steep angle conveying system can also be designed for large-scale conveyance applications.
The system’s key components include the world’s largest and heaviest profile pipe belt, which was developed by ContiTech with a maximum diameter of 900mm, a width of 3200mm and a strength of 9500N/mm, and the innovative DirectDrive concept from Siemens. These drives are available with installations of six megawatts (6MW) and more.
