The intermodal equipment pool remains one of the most contentious cost centers for drayage fleets. Carriers routinely receive chassis pool invoices that apply broad average mileage allocations or rely on mechanical hubodometers that have been tampered with, misread, or simply failed. These invoices frequently include tire lease surcharges and maintenance penalties that bear little resemblance to the actual road miles traveled under each interchange agreement.
Strong Tower Consulting, LLC has helped numerous motor carriers replace these legacy practices with precise, tamper-evident axle-mileage telemetry. The solution combines wireless digital hubodometers, real-time magnetic axle rotation sensors, and dual GPS reconciliation inside the CheckPoint platform (a sister company technology). The result is an authoritative, audit-ready record that defeats disputed billings and drives measurable reductions in tire and maintenance expense.
The Disputed Equipment Pool Mileage Bill
Most chassis pool agreements base maintenance and tire lease charges on either mechanical hubodometer readings or fleet-wide average utilization. Mechanical devices are prone to failure, reversal, or manual "pencil whipping" during yard checks. Pool operators often default to conservative estimates that overstate mileage for high-utilization carriers. The outcome is predictable: inflated tire lease surcharges, premature brake and wheel-end maintenance penalties, and hours of non-productive audit time reconciling TMW, McLeod, or Truckmate settlement records against pool invoices.
When these charges reach the accounts-payable desk, dispatchers and maintenance managers are left defending line-haul EDI 214 status updates and driver settlement records that were never designed to govern chassis-specific axle mileage.
The Strong Tower AxleMetric Architecture™
Our architecture replaces guesswork with continuous, multi-source axle-mileage governance. Three core components work together inside the CheckPoint platform:
- Wireless digital hubodometers with magnetic axle rotation sensors. CheckPoint captures precise wheel revolutions at the axle. The system automatically factors current tire tread depth and rolling radius in real time, producing true distance traveled rather than raw revolution counts. Data transmits wirelessly to the CheckPoint dashboard (https://exspeeditecheckpoint.com/login.php).
- Dual GPS breadcrumb and mechanical axle reconciliation. Tractor GPS line-of-road mileage is continuously cross-checked against chassis axle revolutions. Discrepancies immediately flag unauthorized chassis swaps, piggybacking, or yard movement that would otherwise distort pool billing. This reconciliation also supports accurate fuel surcharge and detention calculations when integrated with your TMS.
- Automated tire wear and PM interval scheduling. Predictive algorithms flag chassis approaching 10,000-mile inspection thresholds, brake lining wear limits, or tire casing replacement targets. Maintenance dispatch receives prioritized work orders that align with actual usage rather than pool averages.

Overturning Unfair Intermodal Equipment Pool Over-Mileage Penalties
CheckPoint generates tamper-evident, trip-by-trip mileage certificates that align directly with interchange agreements. These certificates reconcile axle rotation data against GPS breadcrumb trails and EDI 214 status messages. When a pool operator presents an overstated tire lease or maintenance invoice, the carrier can produce a PDF report showing exact road miles traveled under that specific chassis during the billing window.
This documentation has proven decisive in disputes involving major intermodal chassis providers. Carriers using the platform routinely reduce contested charges by more than 85 percent while simultaneously extending tire casing life and reducing roadside breakdowns.
Strong Tower Consulting, LLC and Exspeedite LLC are separately organized sister companies under common ownership (separate EINs; liability firewall). We lead intermodal technology. Carriers never have to buy our software. Our role is to deliver independent technology strategy, implementation oversight, and audit defense. Founded in 2008 in Minnesota by Scott Elliott.

Implementation Considerations for Drayage Fleets
Successful deployments integrate CheckPoint axle telemetry with existing TMS platforms (Truckmate, McLeod, or TMW). SQL views can pull reconciled axle-mileage data directly into driver settlement tables, fuel surcharge calculations, and detention reporting. EDI 204 tender and 210 freight invoice workflows remain unchanged while gaining a new layer of equipment-level precision.
The wireless sensors are compatible with both oil-bath and grease-pack wheel hubs. Installation is performed during routine PM service with no impact on equipment availability. Data transmission occurs automatically when the chassis returns to a equipped terminal or yard.
Frequently Asked Questions
- Can CheckPoint digital hubodometers detect reverse tractor movements or yard switching?
- Yes. The magnetic axle rotation sensors register direction of rotation. The platform distinguishes between forward line-haul miles and reverse or low-speed yard movements. This capability prevents pool operators from allocating yard-switching time against a carrier's road-mileage allowance.
- Are the wireless hub sensors compatible with oil-bath and grease-pack wheel hubs?
- Yes. The CheckPoint sensors are engineered for both oil-bath and grease-pack configurations. Installation requires no modification to the hub assembly and is performed by certified technicians during scheduled maintenance.
- Does the platform automatically alert maintenance when a chassis exceeds brake lining wear mileage?
- Yes. Predictive maintenance rules can be configured for any threshold, including brake lining wear, wheel-end service intervals, or tire tread depth. Alerts are delivered via the CheckPoint dashboard, email, or directly into your existing maintenance management module.
- How does axle-mileage telemetry improve driver settlement accuracy?
- Reconciled chassis mileage data feeds directly into settlement tables, ensuring fuel surcharge, detention, and accessorial calculations reflect actual equipment usage rather than pool averages. This eliminates disputes between driver pay records and chassis pool invoices.
