Colorado Quad-Axle Dump Fleet
One of the largest quad-axle fleets in Colorado — 25-yard straight dumps permitted for up to 95,000 lbs GVW and a typical payload of 28–32 tons on most non-interstate roads.
Trailer-Class Tonnage, Dump-Truck Speed
Quad-axle dump truck — four-axle configuration with a steer axle, tandem rear drive axles, and two lift (pusher) axles. Not tractor-trailers or branded SuperDumps. Under Colorado's Non-Interstate Overweight Divisible (NIOWD) Quad Axle permit, each truck can legally haul far more sand, gravel, dirt, millings, and similar divisible materials than a standard tandem or tri-axle.
Why the NIOWD Quad Permit Matters
Colorado's NIOWD Quad Axle permit is the legal hook that turns a 25-yard quad into a 32-ton hauler. A properly configured quad-axle dump — four consecutive axles whose extreme centers are no more than 96 inches apart, with a load-equalizing mechanism — can run up to 95,000 lbs gross vehicle weight on state highways and most other non-interstate roads.
That covers the roads that actually serve pits, plants, and job sites across Douglas County, the Front Range, and many mountain reconstruction routes. It does not apply on I-25, I-70, I-76, I-225, or I-270, and all loads must comply with CDOT's Bridge Weight Limit Map.
Sand, gravel, dirt, millings, and similar construction materials are divisible loads and qualify.
How 32 Tons Compares
On a heavy 25-yard quad that empties in the low-30,000 lb range, 95,000 lbs GVW produces a typical payload of 28–32 tons — exactly what contractors need for earthwork, paving, and aggregate hauls off the interstates.
Fewer Trips, Lower Cost Per Ton
Fewer loads, same job
- 28–32 tons vs ~14 on a tandem — roughly half the loads for the same cubic yards or tons
- 10,000-ton earthwork job? ~714 tandem loads vs ~313 quad loads
- Less congestion at the pit, on the haul road, and at the dump point
Lower unit cost
- Driver, fuel, insurance, and shop time spread over far more tons per trip
- As much as 43.6% cheaper per ton to haul with us vs standard tandem loads
- One well-utilized 32-ton truck can replace 2 lighter trucks on many Front Range jobs
Still a rigid dump truck
- Dump in place — no unhooking a pup or transfer trailer
- Better maneuverability on tight residential, commercial, and mountain sites
- Faster turnaround on short- to mid-range hauls
- 25-yard body: full load of lighter material or partial load of dense wet dirt/gravel to stay at or below 32 tons
Bidding advantage
- Quote lower haul rates or tighter schedules because unit cost is better
- Contractors notice when one truck moves what used to take two
- Especially useful on CDOT and county work using state highways — Colorado Springs, Front Range, mountain reconstruction
Less to manage on site
- Fewer trucks on the job site — less staging, less conflict with other trades, smaller footprint
- Faster load times at the pit or plant — fewer trucks in the queue ahead of you
- Quicker turnaround — more tons moved per hour on short- to mid-range hauls
- Fewer trucks and drivers for your team to oversee, dispatch, and track
- Simpler scale tickets and load counts — half the paperwork on big quantity jobs
- Less haul-road wear and fewer access-point conflicts on tight sites
More production, less hassle
- Fewer total trips means less idling, less queue time, and faster job completion
- Reduced traffic through neighborhoods and commercial sites during delivery windows
- One reliable quad often outperforms two lighter trucks that may arrive out of sync
- Easier to coordinate with paving, grading, and placement crews on a tight schedule
What to Know
- No interstates under this permit. I-25 or I-70 moves drop back to legal USDOT weight limits unless a different permit applies.
- Bridge Weight Limit Map. Some structures are posted lower even for permitted trucks.
- Local roads. City and county streets can add their own limits; the state permit does not override them.
- Operating cost. Extra axles mean more tires and brakes, but the payload gain usually more than pays for it on volume work.
- Not a SuperDump. SuperDump is a brand with a trailing axle for extra legal weight via wheelbase length on interstates. Our quads trade that route flexibility for higher Colorado non-interstate payload and lower specialized-equipment cost.
