A rock truck is an articulated off road hauler built to carry spoil and aggregate across ground no highway truck can reach, and it hires for roughly $900 to $2,200 a day depending on payload class. Before you price one, be sure the material really has to move on site rather than off it, because a highway dump truck is the cheaper answer for anything that leaves by road.
On site hauler, not a road truck
These machines are unlicensed for public roads. They exist to shuttle material between a cut and a fill, a quarry face and a crusher, or a dig and a stockpile, over surfaces that would bury a tandem axle truck. If your spoil is going to a tip miles away, you want road haulage and a loader, not this.
Payload classes and what they mean
The common rental sizes carry roughly 25, 30 and 40 tons, and the number is weight rather than volume, so heavy wet clay fills the body long before light dry fill does. Match the truck to the loading machine as well: a bucket that needs eight passes to fill a body wastes both machines.
Haul road quality decides your cost
Cycle time, not day rate, sets the cost per ton moved. A graded, drained haul road with gentle gradients can double what one truck shifts in a shift, which is why big earthworks jobs keep a dozer or grader on the road full time. Budget for that machine when you budget for the trucks.
Mobilising a hauler onto your job
A 40 ton class hauler travels on a heavy float, sometimes in more than one load, and mobilisation is quoted each way and separately from the hire. Ask for the delivered price with a return date attached, and confirm the access route can take the transporter before the day it arrives.
Questions people ask about rock trucks
What is the difference between a rock truck and a dump truck?
A rock truck articulates in the middle, runs on large flotation tires and is built for rough unmade ground on a job site. A dump truck is a highway vehicle on a rigid chassis that carries less off road and cannot climb a muddy haul road. They are not substitutes for each other.
How many rock trucks do I need for one excavator?
It depends on cycle time. Work out how long the loop takes, divide by the time the loading machine needs to fill one body, and round up. Short hauls may keep an excavator busy with two trucks; a long uphill haul can need five.
Can I rent a rock truck by the week?
Weekly and monthly rates are the normal way these are hired, because mobilising a machine of this size for a single day rarely makes sense once transport is added. Ask what hours the rate covers, since many contracts meter at a fixed number of hours a week.
Does the hire come with an operator?
Some yards offer operated hire on the larger classes and some hire the machine bare. If you are taking it bare, the employer is responsible for training and authorising whoever drives it, and the yard will want to know who that is.
