Technical Breakdown
ADT 25-30 tonne class
General off-road haulage on civil earthworks, industrial platforms, and smaller mining contracts. Right choice where haul road conditions vary and larger rigid haulers cannot manoeuvre.
ADT 35-40 tonne class
Higher payload for larger civil earthworks, mid-size mining, and haulage where off-road conditions still rule out rigids. Matched to 5m³ loader class for three-pass loading.
Rigid 40-55 tonne class
Smaller mining haulage on established roads. Higher road speed and lower fuel per tonne than ADTs, at the cost of terrain flexibility.
Rigid 60-90 tonne class
Large mining haulage on hardened roads with controlled grade and radius. Continuous-shift production for open-cast coal and chrome operations.
Load matching
Three-pass loader-to-truck fill is the efficient target. Four passes tolerable. Beyond four, truck utilisation drops and cost per tonne rises.
Haul road prerequisites
Established mining roads with controlled grade (typically under 10 percent), controlled corner radius, and maintained surface are the prerequisite for rigid haulers. ADTs handle poorer conditions at reduced payload.

Frequently Asked Questions
How do I choose between an ADT and a rigid dump truck?
It comes down to haul road condition, terrain, and cost per tonne. ADTs are articulated with all-wheel drive, making them the right choice for off-road terrain, soft or wet ground, variable haul road grades, and civil earthworks where you cannot guarantee road conditions. Rigid dump trucks carry more payload and burn less fuel per tonne on well-maintained mining haul roads, but they need those roads: controlled grade under about ten percent, controlled corner radius, and a maintained surface. On established mining operations with hardened roads, rigids are almost always cheaper per tonne. On civil earthworks or new mining sites where roads are still being built, ADTs are usually the better choice.
Do your dump trucks come with operators?
Yes. All Powercall Civils dump truck hire is operator-driven. Dump truck operation on active mining haul roads is a genuine skill — cycle discipline, safe passing, and maintaining haul road condition through good driving practice. Operators carry current mining medicals and site-specific inductions where the operation requires them. We do not supply dry hire on dump trucks.
How is loader class matched to dump truck payload for efficient loading?
Three passes per truck is the efficient target for load matching. A Cat 966 class loader (about 3m³ bucket) is undersized for a 40 tonne ADT — you would need five or six passes and cycle time collapses. A Cat 980 class loader (about 5m³ bucket) loads a 35 to 40 tonne ADT in three passes. Larger mining-class loaders (Cat 992 and above, 8m³+ buckets) match the 60 to 90 tonne rigid trucks. Getting this matching right at quoting stage is the difference between quoted production and delivered production.
Can you handle continuous-shift mining haulage?
Yes. Continuous-shift mining production is a substantial part of the Powercall Civils dump truck deployment, particularly across the Mpumalanga coalfield and chrome operations. Continuous shift work requires duplicated operator coverage, planned maintenance windows, and on-site spares. Crews are built around the shift pattern (single, two-shift, or 24/7) rather than treating night work as overtime. Mechanical availability targets and downtime accountability are documented daily so production planning runs on real uptime data, not aspirational figures.
