Main Power Cable• Distance from the Sub-Station to the Shovel (~ 3 Km)
• Diameter of the Main Power Cable (max. 80cm)
3. Folie 3
Alignment• Positioning and Mountings
• Run-out of the coupling halves
4. Folie 4
Alignment• Repair - Motor change - Alignment
• Coupling halves – disassembly & assembly
5. Folie 5
Alignment• Alignment of the coupling to PTO
• Alignment check with “Aligneo”
6. Folie 6
Alignment• Alignment Values 0,05 – 0,10 mm
7. Folie 7
First Start-up during commissioning• Direction of Rotation
• Sub-Station – Basic setting
• Motor Protection Relays - Basic setting
8. Folie 8
Starting and Re-starting• Number of starts – 2 times / day at least 1000 starts / year
• Re – starting according winding (145C°) and bearing temperature (90C°)
• Mine Net-Line supply variation of max. 5% (7200V ~ 360V)

Maintenance & Preventive Maintenance• Bearing greasing & Re-greasing
• Interval & volume at the Type plate
• Greasing at motor running
• Check specified quality of grease
• Be special rolling bearing grease
• Lithium complex & mineral oil
• Oil viscosity of 100 to 160cSt at 40°C
• continuous temp. range - 30 to + 120°C
ABB recommends grease
• Esso Unirex N2,N3 or S2
• Mobilith SHC 100
• Shell Albida EMS 2
• SKF LGHQ 3
• FAG Arcanol TEMP 110
• BP Energrease LCX 103
