One of the most common questions from Saudi project managers and site engineers is: how many tons can a dump truck actually carry? The answer depends on the truck class, its configuration, and the material being transported. This guide provides definitive answers for metric ton capacities used across Saudi Arabia's construction and mining sectors.
Metric Ton Capacities by Truck Class
Saudi Arabia uses the metric ton (1,000 kg) as the standard unit for dump truck payload across all industries, from residential construction to Maaden mining operations. Here is a breakdown by truck class:
- Dyna / Small Truck: 3 to 8 metric tons. Used for light urban delivery and small-scale construction.
- Standard Dump Truck: 10 to 25 metric tons. The most common class for Saudi construction sites.
- Articulated Dump Truck: 25 to 40 metric tons. Used on large Vision 2030 infrastructure projects.
- Rigid Dump Truck: 30 to 60 metric tons. For quarries and open-cast mining.
- Off-Highway Dump Truck: 40 to 100+ metric tons. Mining and mega-project earthmoving only.
Converting Tons to Cubic Metres for Common Saudi Materials
| Material | Density (t/m3) | 20-ton truck load (m3) | Common Saudi use |
|---|---|---|---|
| Desert sand (dry) | 1.4-1.5 | 13-14 m3 | Construction fill, NEOM site prep |
| Construction sand (wet) | 1.6-1.9 | 11-13 m3 | Concrete production, Riyadh/Jeddah sites |
| Gravel/aggregate | 1.5-1.8 | 11-13 m3 | Road base, foundations |
| Limestone | 2.2-2.5 | 8-9 m3 | Quarry output, road construction |
| Compacted soil | 1.8-2.1 | 9-11 m3 | Excavation spoil, earthworks |
Saudi Road Legal Limits
Saudi Arabia's Ministry of Transport enforces GCC-standard axle load limits. A standard 6-axle dump truck can carry up to approximately 30-35 metric tons on Saudi national highways while remaining within legal weight limits. Off-highway trucks carrying 40-100 tons operate exclusively on private project roads and do not have Saudi road access without special permits.
Practical Cycles Per Day on Saudi Sites
On a typical Riyadh construction site with haul distances of 5-15 km, a standard dump truck completes 8-12 load cycles per day. At NEOM, with internal site roads of 3-8 km, articulated trucks can achieve 12-18 cycles per day. This means a single 20-ton truck can move 160-360 tonnes per day depending on conditions.
