The conveyor is actuated by three synchronized drive units for a total power of about 1.8 MW supplied by ABB (two drives at the head end in Bangladesh and one drive at the tail end in India). The conveyor belt was manufactured in 300-meter lengths on the Indian side and 500-meter lengths on the Bangladesh side, and was installed on-site by BeltPro (formerly NILOS India). The idlers, or rollers, of the system are unique[citation needed] in that they are designed to accommodate both horizontal and vertical curves along the terrain.
