Looking into Flame Proofing Options for Demolition Robot
- Brokk approached and inspected• Existing Solenoids used as is (electrical supply to be converted)
• All cabling to be converted to collectively screened cable
• Supply cable to be changed for individually screened standard cable
• Electric ABB motor to be exchanged for a flameproof version
• Lights to be LED, thus not requiring heavy steel flameproof enclosures
• All electrical components to be housed in flame proof compartment
• Upgrade some electrical components to 950 Volt rating
• Include an IS power supply for controls
• Remote module to be further evaluated, including review of electronic circuitry and battery arrangement
