Fleet Vehicle Durable Running Boards

-- Steady & Reliable Manufacturer --

Engineered for High-Cycle Commercial Reliability

This product line is engineered for the rigors of commercial fleet operation, where components are subjected to high usage cycles, frequent heavy loads, and minimal maintenance. The core design prioritizes maximum Mean Cycles Between Failure (MCBF). This is achieved through the use of oversized, sealed bearings, continuous-duty rated motors, and a structural design that minimizes stress concentration.

The steps utilize a simplified, heavy-gauge steel linkage with a reduced number of articulation points to enhance mechanical robustness and simplify maintenance. The control module is programmed with a self-resetting thermal/current fuse logic, which protects the system from repeated heavy-handed misuse or transient overloads without requiring service intervention for minor faults, ensuring maximum uptime for the fleet operator.

The Uptime Imperative for Commercial Fleets

In commercial fleet operations, vehicle downtime directly translates into lost revenue. Our durable running boards are purpose-built to deliver consistent, predictable performance over thousands of daily cycles, maximizing vehicle uptime and minimizing the Total Cost of Ownership (TCO).

With 120 sets of automatic production equipment and an ERP system controlling the internal production management process, our manufacturing is geared for consistency and efficiency in large-batch production. We provide fleet operators with a product verified in our full performance testing center to withstand the highest frequency use demanded by commercial and utility applications.

Application Areas

Delivery and Logistics Fleets: Vehicles with extremely high daily cycle counts (e.g., parcel delivery vans, utility service trucks) where drivers enter/exit hundreds of times per shift.
Municipal and Public Works: Vehicles operated by city services, police, or fire departments that require reliable access in emergency and high-stress scenarios.
Ride-Share and Taxi Services: High-mileage passenger transport vehicles where passenger consistency and step reliability are paramount for customer satisfaction.
Rental Car Agencies: Requires accessories that can withstand rapid turnover, varied users, and inconsistent maintenance schedules while maintaining function.

FAQ

Q: How do you guarantee the 7-year structural corrosion warranty for a fleet operating in severe winter road salt environments?
A: Response: The structure uses Q345 HSLA steel with a proprietary Zinc-rich Epoxy E-coat base layer, which provides superior sacrificial protection to the steel, followed by a heavy texture powder coat. This system is verified by undergoing 2000+ hours of continuous Salt Spray Testing (ASTM B117), exceeding standard aftermarket requirements.

Q: What component has the highest failure rate in high-cycle fleet use, and how has the design been adapted to address it?
A: Response: The pivot bushings and motor brushes are typically the highest wear items. We address this by using oversized, self-lubricating bronze bushings with PTFE lining, and by specifying a Brushless DC (BLDC) motor option for the highest-cycle applications, eliminating the wear component entirely for extended service life.

Q: Is the control module able to restrict step use if the vehicle's battery voltage drops below a safe starting threshold?
A: Response: Yes. The ECU is programmed with a Low Voltage Disconnect (LVD) logic. If the vehicle's electrical system voltage drops below 11.5 V (a pre-start threshold), the steps are temporarily disabled to conserve battery power for engine starting, ensuring the vehicle remains operational.

Features for Fleet TCO Optimization

Oversized Pivot Hardware: Utilizes larger diameter, hardened steel pins and high-load bronze bushings, which significantly increase the bearing surface area and extend the time between wear-related service intervals.
Modular Design for Service: Key components (motor, linkage, step platform) are designed for rapid, modular replacement with standard tools, allowing fleet technicians to perform repairs quickly and minimize vehicle time out of service.
High-Wear Tread Replacement: The non-slip tread is designed to be easily removable and replaceable without replacing the entire aluminum step body, reducing long-term maintenance costs.
Extreme Weather Lubrication: Critical moving components are packed with a synthetic, high-viscosity, extreme-pressure (EP) lubricant that maintains its properties from −40∘C to +60∘C.
Simplified Diagnostic Interface: The ECU features a simple status LED or basic fault code output, allowing fleet maintenance staff to perform quick first-level diagnosis without proprietary external tools.

Production Protocols for Commercial Grade Consistency

Manufacturing and quality control procedures focused on maximizing MCBF.

Automated Lubrication: The assembly line utilizes precision, automated dosing equipment to inject the exact volume of high-EP synthetic grease into the gearboxes and pivot points, ensuring consistent lubrication quality across all units.
Extended Cycle Testing: A dedicated fleet test rig runs samples to the 200,000 cycle MCBF target on an ongoing basis. Data is fed into the ERP system to continually validate and improve component sourcing.
Fleet Specific Packaging: Kits are packaged with robust, recyclable industrial packaging with clear, large-print labels and QR codes for efficient receiving and inventory management at large fleet distribution centers.

Material Selection Focused on Longevity and Maintenance

Materials chosen for wear resistance and ease of servicing.

Linkage Material: Heavy-gauge Q345 High-Yield Steel, selected for its resistance to both fatigue and sudden impact deformation.
Pivot Bushings: High-load, sintered SAE 660 Bronze (or equivalent) with a self-lubricating graphite core, designed for thousands of cycles without requiring external grease application.
Tread Insert: Uses a specialized, high-density EPDM rubber or thermoplastic elastomer (TPE), formulated for high abrasion resistance and UV stability, installed via a non-permanent mechanical locking system.
Fasteners: Exclusive use of anti-vibration locking nuts (e.g., prevailing torque nuts) on all critical structural joints to prevent loosening due to high-frequency road vibration.
