Komatsu provides complete electrical packages for tunnel conveyor systems from the interface to the TBM. These electrical packages include variable frequency drive systems. Belt drive control is achieved by the use of PLC-controlled VFD systems to give total control of starting and stopping. This is particularly important in long conveyor systems.
The PLC VFD combination is essential in the control of tripper booster systems. Precise power input and belt tension control are achieved when Komatsu conveyor modelling software is employed. We can provide a concise data information package encompassing system control logic and complete monitoring of drive systems and all in-built safety protection devices. This improves safety and provides high operational performance.
