- Country: Czech Republic
- Name: Mining machine Staric III /6B Chlebovice
- Date: 2012
- Control system: Tecomat TC700, CP-7004
- Software: Mosaic
- Implemented by: INCO engineering, s.r.o.
Tecomat TC 700 has been used by company INCO engineering as control system of mining machine. It is two cylinders machine with possibility of disconnecting cylinders. One cylinder is winding wire rope from the upper side, the second one from lower side. That´s why one container is moving in one direction and the other one in opposite direction. After cylinders disconnecting the containers distance may be changed, what means from which floor to whom the containers can move.
Control system Tecomat TC700 controls all mining machine. It controls even brake system - operation brake and accident brake.
There is another independent control system, which provides operation control and meets mining regulations, performing all machine operations. It contains control of temperature statuses, pressure statuses of used mediums, speed statuses and safety requirements.
Power of mining machine is 3500 kW. Current of motor is 4200 A at 900 V. Container may load 10 t weight. Deep of mine, where machine operates, is 900 meters. Servo drive is DC, thyristor, 12-pulse in serial connection. Reversing of drive is made in anchor circuit of mining motor.
