In a groundbreaking urban renewal project in Singapore, 20 refurbished Cat 320 excavators (21-22 ton class) were deployed as the core equipment for transforming aging infrastructure into smart urban spaces. These versatile machines demonstrated exceptional adaptability in challenging city environments.
Key Applications
Precision Demolition
8 units equipped with AI-assisted demolition systems selectively dismantled structures with 95% material recovery rates
Noise-reduction kits enabled nighttime operation in residential zones
Automated Construction
6 excavators retrofitted with semi-autonomous controls worked alongside robotic concrete printers
Laser-guided grading achieved millimeter-level accuracy for smart road foundations
Green Space Development
6 machines installed vertical gardens and urban farming systems using specialized attachments
Standout Advantages
✔ Smart Retrofit Capability – IoT sensors provided real-time performance monitoring
✔ Eco-Efficiency – Biofuel compatibility reduced carbon emissions by 30%
✔ Urban Adaptability – Compact dimensions (2.5m width) allowed access to tight spaces
Project Success
The fleet completed work 25% faster than scheduled while:
Reducing material waste by 40% through intelligent sorting
Maintaining 98% operational availability throughout the project
Post-project, these Cat 320s were repurposed for Malaysia's next smart city development, proving that well-maintained used excavators can deliver new-equipment performance at half the cost.
This case demonstrates how strategically upgraded used Cat 320s can become valuable assets for sustainable urban development, combining reliability with modern technological enhancements.oject.
