1. Haulage Optimization from Regional Quarries
Basalt gravel from Debre Zeit and river sand from Awash must cross ring-road checkpoints with strict axle-load limits. Specifying 20m³ three-axle dump trucks reduces cost per cubic meter by 18% compared to smaller tippers.
2. Mobile Crane Sizing for Precast Erection
Before renting mobile hydraulic cranes, verify outrigger ground-bearing pressure on compacted fill, boom radius charts at 75% load capacity, and road width for equipment positioning.
