The movement of 400-ton precast concrete and steel bridge spans across temporary falsework, steep approach ramps, and active river crossings represents one of the highest-risk operations in heavy civil infrastructure. A single hydraulic valve leak or differential ground compaction of less than one inch across a 150-foot span can shift hundreds of tons of live load onto a single crawler track. The result is often structural cracking in the concrete deck or complete crawler tip-over.
Strong Tower Consulting has supported specialized heavy haul carriers and bridge contractors for more than 18 years in developing verifiable, sensor-driven controls that eliminate these failure modes. Our BridgeJackShield Architecture integrates real-time hydraulic pressure transducers, dual-axis laser elevation sensors, and automated center-of-gravity telemetry inside the CheckPoint platform to deliver continuous load equalization across 32 or more lifting points.
Operational Imperative: Multi-Point Hydraulic Jacking Equalization
Modern bridge construction frequently requires the transport of multi-span girders weighing 350-500 tons using synchronized hydraulic crawler transporters. These machines operate on temporary steel falsework, compacted earthen ramps, and existing bridge decks that were never designed for such concentrated live loads. Traditional manual fluid sight gauges and post-move paper logs cannot detect dynamic load shifts that occur in real time.
A 1-inch height discrepancy between any two crawler tracks instantly redistributes load. When this occurs under a 400-ton girder, the resulting moment can exceed the design capacity of both the falsework and the crawler chassis. State DOT bridge engineers now require digital proof that structural loading remained within engineered limits for the entire duration of the crossing.
The Strong Tower BridgeJackShield Architecture
BridgeJackShield combines three synchronized data streams inside the CheckPoint platform (accessible at https://exspeeditecheckpoint.com/login.php):
- High-precision hydraulic circuit pressure equalization - 32 independent transducers sample cylinder pressures every 10 milliseconds. The system maintains load balance within 2% across all crawler dollies regardless of terrain-induced chassis twist.
- Dual-axis laser ground elevation and chassis level radar - Deck attitude is measured to 0.05 degrees of pitch and roll. When thresholds are approached, the system automatically commands hydraulic compensation before structural twist limits are reached.
- Automated state DOT bridge engineering transit dossier - Every move generates cryptographically signed PDF and JSON logs proving continuous compliance with the engineered load distribution plan. These files are accepted by state bridge offices in lieu of manual calculations.
This architecture operates independently of the carrier's primary TMS. Whether you run Truckmate, McLeod, TMW, or a custom SQL-based dispatch system, CheckPoint functions as a parallel safety layer. EDI 204 tender data, driver settlement records, fuel surcharge calculations, and detention billing remain untouched in your core system.

Flawless Hydraulic Balance for Mission-Critical Civil Infrastructure
Bridge contractors and specialized heavy haul operators using CheckPoint report consistent elimination of load-shift incidents. The system not only prevents catastrophic events but also dramatically reduces the engineering review cycle for state DOTs and railroad bridge owners. Real-time remote dashboards allow bridge engineers to monitor pier reactions and crawler loads from their offices during critical river crossings.
Because Strong Tower Consulting, LLC and Exspeedite LLC are separately organized sister companies under common ownership (founded 2008 in Minnesota by Scott Elliott), carriers retain complete operational independence. You never have to buy our software to receive expert guidance on heavy haul process improvement, TMS optimization, or safety system integration.

Frequently Asked Questions
- How do multi-point laser elevation sensors measure deck level across undulating temporary haul roads?
- Dual-axis laser transmitters mounted on fixed falsework piers create a reference plane. Receivers on each crawler dolly report height deviations at 50-millisecond intervals. The CheckPoint algorithm converts these readings into pitch, roll, and twist values, then issues automated hydraulic commands before any structural member exceeds its allowable deflection.
- Can state bridge engineers monitor real-time pier and crawler loads remotely during the river crossing?
- Yes. CheckPoint provides secure, read-only web dashboards and API access that authorized DOT personnel can use from any location. Live hydraulic pressure, laser elevation, and calculated load distribution values are displayed alongside the engineered limit envelope. All data is logged with digital signatures acceptable for final as-built documentation.
- Does CheckPoint halt crawler propulsion automatically if hydraulic cylinder pressure exceeds safety limits?
- Yes. When any cylinder pressure deviates beyond the configured tolerance (typically 2% of target load), the system issues a progressive warning followed by an automatic propulsion inhibit if the imbalance is not corrected within 800 milliseconds. This safety interlock has prevented multiple potential tip-over events on projects in the Upper Midwest and Pacific Northwest.
- How does this technology integrate with existing heavy haul TMS platforms such as Truckmate or McLeod?
- CheckPoint operates as a parallel, purpose-built safety and compliance system. It ingests load and route data via API or EDI 204 but does not replace your primary dispatch, driver settlement, fuel surcharge, or EDI 214/210 processes. This separation maintains the liability firewall between operational TMS and specialized superload telemetry.
