Gearless conveyor drives (GCD) for high power

Ensuring that longer, higher capacity and technically more demanding mining conveyor systems (>10MW) will operate with maximum availability and reliability and with the lowest possible operating costs

ABB’s gearless conveyor drives (GCD) enable the design and construction of high torque conveyors which go to the limit of belt strengths and pulleys.

Synchronous motors (2.5 - 9MW, 50-60rpm / 400 - 1700kNm) are embedded onto a special base frame which allows to transport the motor in a piece, to perform shortest installation time as well as quick and easy alignment of the motor to the pulley.

Combined with ABB’s dynamic Direct Torque Control and network friendly VFDs the GCD for high power fulfills the highest standards and requirements.
