In construction, mining, and environmental rehabilitation projects, ground bearing pressure (GRP) directly impacts operational feasibility, safety, and environmental compliance. Yangyu Heavy Machinery pioneers this frontier with its Low GRP Crawler Crane series—engineered to deliver unmatched stability on soft soils, wetlands, and environmentally protected sites. With ground pressures as low as 3.5 psi (compared to conventional crawlers’ 8-12 psi), Yangyu’s solutions enable projects previously deemed impossible while reducing site preparation costs by up to 60%.
Ecosystem Preservation: Minimizes soil compaction in wetlands, tundra, and agricultural lands 6
Unstable Terrain Access: Operates confidently on sand, mud, and reclaimed land without sinking risks
Cost Efficiency: Eliminates 70% of matting/ground reinforcement requirements
Regulatory Compliance: Measts ISO 14001 environmental standards for sensitive area operations 18
1. Patented Crawler System
Wide-Link Tracks: 900mm ultra-wide segments distribute weight across 40% larger surface area
Modular Track Extensions: Bolt-on widen kits adapt ground pressure from 3.5–5.2 psi for varying soil conditions 6
All-Terrain Drive Motors: High-torque hydraulic propulsion maintains 2.5 km/h speed even at 25° inclines
2. Adaptive Structural Design
Variable Counterweight System: Automated sliding weights optimize balance during lifts without increasing ground pressure
Telescopic Boom Architecture: 18–52m reach eliminates need for outriggers on confined sites
3. Hybrid Power Ecosystem
Diesel-Electric Configurations: Regenerative energy recovery captures 22% of lowering/rotation energy
Silent Mode Operation: <68 dB electric-only operation for urban night shifts 7
