Brief description

The unloader is generally contracted by US BLACK&VET​CH Company which belongs to Japan Sumitomo Indonesia TJB plant projεect. HiTECH is a subcontractor who is responsible for≠ the electrical control system design, product supply,​ debugging and after sale service of the unloader and bucket whee♦l machine. The project design, manufacture and deb"ug pass the BV strict examination.

Mechanical parameters of the unloader: rated hoisting weight is 35t, rated pro¶ductivity is 1500t/h, maximum productivity is 1800t/h, ♥rated hoisting speed is 130m/min, unload hoisting speed is 150>m/min, cart rated speed is 220m/min, carrier rated speed is 25m/min, cart seaside stroke is 35m®, landside stroke is 18m. Hoisting height is 20.5m over the carrier tra±ck and 10m under the carrier track.

The electrical parameters of the unloader: machine power 10KδV, cable drum power supply, main transformer DYn11 2000KVA 10KV/0.5KV, secondary transfγormer DYn11 315KVA 10KV/0.4KV. hoisting support, motor switching: 500KW 500VAC, cart motor: 315KW φ500VAC, pitching motor: 90KW 500VAC, carrier motor: 8 18.5KW 400VAC‍

Solution

HITE integration is used as the electrical control system. The transmission module uses ABB ACS8$00 series ISU multi-transmission product. PLC uses Sch>neider QUANTUM series and remote I/O series product. PLC comm≠unicates with speed regulator by PROFIBUS-DP, exchanging data in the speed at maximum 12$Mbps and fully monitoring the working status and detail informat®ion of the speed regulator. PLC communicates with CMS  and touch screen by 1∞0/100M industrial Ethernet to construct the monitoring management system which real-time moni₩tors the system working condition, provides complete fault information and make the §running and maintenance easier.
