USA/Solutions/By vehicle/Dump trucks & mixers
Concrete mixers and dump trucks
A loaded mixer is top-heavy, running against the clock, and backing onto a job site nobody has walked since yesterday. MANTIS puts cameras on every side of it, the drum and chute included, so you can see what happens around the truck and keep the record from the batch plant to the chute.
Predict the risk. Prevent the collision. Prove what happened.
Built for U.S. ready-mix and construction fleets: rear- and front-discharge mixers, tandem and tri-axle dump trucks, and the trucks that run between the plant, the pit and the site.
Camera count, drum and chute views, night vision and AI detections depend on configuration. Finding video within 60 seconds assumes the truck is powered and connected; a month of footage depends on the recorder configuration. Assistance supports driver judgment; it does not replace it or guarantee prevention. Images on this page are illustrative and AI generated, pending fleet photography.
Damage, injury and claims
Damage happens at five miles an hour behind the truck, on a right turn with a full drum, and at the chute when the contractor says the load was wrong. A forward-facing dashcam sees none of it.
01
NRMCA’s 2017 rollover survey found most mixer rollovers happen with a loaded drum on dry, level pavement, and pointed to drivers losing focus. Not ice, not a hairpin. A routine run, and the driving habits behind it show up in the event data months earlier, if someone is watching.
02
Forms, rebar, pump hose, a homeowner’s driveway, and people standing where they should not be. A spotter helps, but that spotter does not always see both sides of the truck at once. NRMCA has found 11% of a mixer fleet has a backing accident in a year (Concrete Products, 2008).
03
When a slab fails three weeks later, the bill lands on the concrete unless the record shows arrival inside the discharge window, the drum turning, and what happened at the chute.
04
Pump booms, conveyor belts and raised dump bodies reach into overhead power lines. Crew reach toward the hopper or climb the ladder while the drum is still turning. Side and drum-view cameras show who was standing where, so the near miss gets talked about the next morning, with the footage on the table.
Sources. 10x compares a mixer rollover rate of 0.5% a year (NRMCA 2014 Fleet Survey) with an average of 0.05% across all vehicles, most of them passenger cars. 794 is an estimate built from NRMCA benchmarking surveys; federal data does not track mixer trucks separately from other Class 8 trucks. 357 includes mixers and dump trucks (ENR, 2018). MANTIS RECON is a collision prevention and evidence system; it does not replace safe work practices, trained spotters or site planning.
Camera coverage
A typical mixer configuration puts cameras where the day actually goes wrong: ahead, down both sides, across the rear, over the drum and chute and, if you choose, in the cab. Every view records continuously and can be pulled through RECON, so the plant sees what the driver saw.
Camera positions, counts and AI detections depend on the configuration selected for each truck type. Dump trucks, front-discharge mixers and pump trucks need a different layout; ask us about yours.
Multi-cam video, delivered quickly
Even when no event was detected: the slab complaint three weeks later, the cracked driveway, the standby hours nobody can prove. Predict, Prevent and Prove, tuned to a mixer fleet.
Predict
Harsh cornering and G-force events arrive with the video attached, so you can see which drivers are taking turns the way mixers roll, and raise it while it is still a conversation. Scores are relative comparisons that tell you where to look first. They are not a forecast that a rollover will happen.
Prevent
No camera stops an accident on its own. It makes the risk visible. Side and rear cameras show who is standing behind the truck, walking under the chute or working without a hard hat, so a manager can raise it the next morning. The driver-facing camera flags phone use, fatigue and seat belt events for review.
Prove
Time-stamped, multi-angle video of the arrival time, the drum turning and the discharge. Pull it remotely and share it with the contractor, the insurer or your attorney.
Risk scores in RECON examples are shown out of 15 and use demo data. A harsh corner may have a reason: review video, context and the driver’s account before drawing a conclusion, and never let a score alone decide an employment, underwriting or liability outcome. Video cannot establish injury severity. MANTIS does not guarantee premiums, settlements, admissibility or legal outcomes. Retrieval within 60 seconds assumes the truck is powered and connected; a month of footage depends on the recorder configuration.
Built for the plant
A mixer lives in washdown, cement dust, vibration and heat, and a camera that died overnight is usually found on the day its footage was needed. MANTIS Health checks every camera, recorder and connection and reports to the plant before the first load goes out.
Offline is not proof of camera failure. Monitoring or power alone does not guarantee useful recording or retrievable footage. Whether a truck with a reported fault takes a load is a decision under your own safety program.

Drivers and budget holders
Two people have to say yes to cameras on a mixer fleet: the driver, and whoever signs off the spend.
For your drivers
When a car cuts in front of the drum or a homeowner says the mixer cracked the driveway, the video is what stands between the driver and a claim in their name.
The driver-facing camera is optional and has a privacy mode for when the driver is off duty. Where fleets use one, retention and who can view video are agreed with drivers before the system goes live.
Driver-facing detections are flagged for review, not decided by the system. A score alone should never decide an employment outcome.
For your budget holders
Start with last year’s costs the footage would have answered: loads disputed or paid late after a slab complaint, backing and property damage claims, standby hours you could not bill without proof of arrival, and rollovers and serious incidents, counting the truck, the downtime and the claim.
Then configure your 360° system and request a price to set against that total.
The figures are yours. MANTIS does not guarantee a saving, a premium change or the outcome of any dispute.
Hardware, software and support
No capital purchase, no separate data plan, no argument about who owns a failed camera. Buy direct from MANTIS, or through your telematics provider or reseller.
Support
Critical camera faults raise a support case automatically, and first-line checks start before you call. Installation, fault handling and replacement are agreed with your team as part of the package terms.
Connectivity
RECON connects across supported U.S. carriers and uncapped data is included in the subscription, so a pit or a rural pour at the edge of coverage is not a reason to lose video. Uncapped data is subject to fair use policy. Network coverage, roaming, plan availability and retrieval performance vary by region and configuration.
Direct or through your provider
RECON integrates with Geotab, so your team works in the telematics platform it already uses. Buy RECON direct from MANTIS, or through the telematics provider or reseller you already work with.
Questions from ready-mix fleets
If yours is not here, put it in the form and a solutions engineer will answer it directly.
Most rear-discharge mixers run five or six: forward, left side, right side, rear, drum and chute and, optionally, driver-facing. Front-discharge mixers and dump trucks need a different layout. Configuration is agreed per truck type, with up to eight cameras on a truck.
Drum and chute views can start recording when the drum reverses to discharge, through a PTO or trigger input. Which input your trucks use is confirmed at the installation survey.
External cameras are rated IP67, and IP69K where high-pressure washdown is part of the day, and are built for -40°F to 158°F with anti-vibration construction. Connectors are sealed and cable runs are routed away from chassis flex and heat at installation.
You can find video from every side within 60 seconds, going back a full month, even when no event was detected. That assumes the truck is powered and connected, and the retention period depends on the recorder configuration, so confirm it for your build.
No. Your backing procedure, including a trained spotter where your hazard assessment calls for one, stays in charge. RECON adds visibility for the driver, health monitoring for the manager and evidence for everyone.
Yes. Tandem and tri-axle dump trucks run on the same platform with a layout built around the body: rear and side views for backing and spreading, and a view of the raised body where overhead lines are a risk on your sites. Tell us the mix of trucks and we will lay out each one.
Yes, or direct from MANTIS. RECON integrates with Geotab, and you can buy through the telematics provider or reseller you already work with, or from MANTIS itself. Tell us which platform you use and we will point you to the right route.
