Connected Solutions and Diagnostic Tools: Remote Monitoring and Guidanz Service Platform
Beyond hardware, Cummins will showcase its digital ecosystem at CONEXPO CON/AGG 2026. The company’s Connected Solutions suite provides remote monitoring and diagnostic capabilities that help fleet managers reduce unplanned downtime and optimize maintenance schedules.
Cummins Connected Solutions for Remote Fleet Management
The Connected Solutions platform collects real-time engine data from equipment operating anywhere on the jobsite. Data transmitted includes coolant temperature, oil pressure, fuel consumption, regeneration status, and fault codes. This information is aggregated in a cloud-based dashboard accessible from any device. Benefits include:
- Proactive alerting when engine parameters drift outside normal ranges
- Remote diagnostics that reduce technician travel time by identifying problems before dispatch
- Fuel usage analytics that highlight inefficiencies in operator behavior or machine routing
- Over-the-air calibration updates for aftertreatment and engine control modules
Guidanz Service Tools
Guidanz is Cummins’ service tool platform designed to support both connected and non-connected equipment. For older machines that lack telematics hardware, Guidanz provides offline diagnostic workflows that guide technicians through fault isolation procedures step by step. The tool integrates directly with Cummins parts catalog systems, so a technician diagnosing a failed injector can immediately check local parts availability and place an order from the same interface.
Additional Products: Ram HD Diesel Engine, Mobile Generator Set, and Meritor Drivetrain Components
The Cummins exhibit at CONEXPO CON/AGG 2026 extends beyond off-highway to include products that support the broader construction ecosystem. Three items stand out for their practical impact on contractor operations.
6.7-Liter Turbo Diesel for Ram Heavy Duty Trucks
Cummins will display a 6.7-liter turbo diesel engine built for Ram Heavy Duty pickup trucks. While not a construction machine itself, this engine powers the service trucks, welding rigs, and crew carriers that support every construction site. The 6.7-liter inline-six configuration delivers the low-end torque that heavy towing and off-road driving demand.
| Engine Model | Primary Application | Key Feature |
|---|---|---|
| 3.8L Power Unit | Compact equipment (skid steers, mini excavators) | Compact packaging, low-speed torque |
| B6.7 | Medium equipment (wheel loaders, excavators) | Common rail fuel system, high durability |
| X15 Off-Highway | Large mining and heavy earthmoving | HVO and hydrogen alternative fuel capability |
| 6.7L Turbo Diesel | Ram Heavy Duty pickup trucks | Inline-six, heavy towing torque |
| 12-kW Mobile Gen Set | Jobsite power generation, Tier 4 Final | Compact footprint, emissions compliant |
The 6.7-liter engine is a reminder that construction fleet planning must consider both yellow iron and the support vehicles that keep it running. For jobsite power needs beyond vehicle engines, Simple and Discreet Countertop Power Solutions for Modern offers practical approaches to integrating power delivery in built environments.
12-kW Tier 4 Final Mobile Generator Set
A 12-kW mobile generator set compliant with Tier 4 Final emissions standards will be on display. This generator set is designed for construction applications where reliable, portable power is needed for tools, lighting, and temporary site offices. The Tier 4 Final compliance means it meets the strictest particulate matter and nitrogen oxide limits for its power class, making it suitable for use in air quality management districts with stringent emissions rules.
Meritor MOX E8 Telehandler Axle and Transfer Case
Cummins will also feature the Meritor MOX E8 telehandler axle and transfer case, a drivetrain component that brings robustness to material handling equipment. Telehandlers require axles that can handle high static and dynamic loads while maintaining steering precision.
