For wood-products haulers, efficiency and uptime are the foundation of a profitable operation. Chips, bark, sawdust, and biomass all move in high volumes, often over long distances, and equipment reliability directly affects mill flow, driver productivity, and per-load cost. KEITH Manufacturing Co., the longtime innovator behind WALKING FLOOR® systems, has introduced its latest advancement designed with these industry pressures in mind.
The company’s new RX Technology platform reflects a complete rethinking of drive-unit performance, reliability, and maintainability—all built to help haulers move more material with less downtime.
While the platform includes multiple drive configurations, the RX2 stands out as the ideal solution for wood-products transport: fast, efficient, lighter in weight, and engineered specifically to remove the maintenance pain points operators have faced for years. The RX3 serves as the higher-capacity option for operations handling heavier or more demanding wood materials, but the RX2 will fit the needs of most chip and biomass fleets.
A New Foundation for Reliability
RX Technology is KEITH’s first major redesign in more than a decade. The engineering process began with a clear objective: reliability is not only about stronger components—it is about eliminating recurring failure points altogether.
Over decades of field service, KEITH’s engineering team identified several small but persistent issues that can compromise long-term drive performance—including corrosion, difficult component replacements, and environmental stressors such as heat and contaminated oil. The RX platform addresses these challenges head-on.
Adjustment-Free Design
Legacy systems used threaded rods and adjustable switching valves, components that required careful calibration and often introduced variability over time. Misalignment, corrosion, or wear could cause improper cycling. The RX design removes these adjustable elements altogether, ensuring consistent operation and reducing long-term maintenance demands.
Ease of Maintenance
A key improvement is the RX’s cartridge-style check valve architecture. Each cartridge can be accessed and replaced quickly with a single wrench, minimizing downtime and simplifying routine service.
Managing Heat—One of the Most Significant Causes of System Failure
Hydraulic heat is a silent threat. When oil temperatures climb, seals soften, efficiency drops, and wear accelerates across the entire system. Traditionally, operators might only detect heat problems after damage has already begun. RX Technology tackles this vulnerability with:
- Integrated heat sensors
- Automatic over-temperature switches
- Early intervention that shuts the system down until oil temperatures reach a safe level
Instead of running until failure, the RX platform intervenes early. This small safeguard extends the life of the drive and helps prevent the cascading failures that lead to costly downtime. For mills and haulers where every hour of uptime matters, proactive heat management is a significant step forward.
RX2: Faster, Lighter, Simpler—Designed for Wood Products Haulers
The RX2 Drive Unit marks a milestone, introducing a two-cylinder moving-floor drive. By re-engineering the hydraulic sequence, KEITH created a drive that unloads faster and weighs less without sacrificing durability.
Unloads a 48-Foot Trailer in About Four Minutes
The RX2’s efficient hydraulic cycle enables extremely rapid discharge of chips, sawdust, biomass, and similar materials. In mills where truck turnaround time affects production flow, this speed advantage can translate into more loads per day and reduced congestion at receiving areas.
A closeup view of the RX2 drive unit shows its innovative two cylinder design, engineered for faster cycling and quicker unloading compared to traditional three-cylinder systems.
Lighter System Weight = More Payload
By eliminating cylinders and simplifying the overall architecture, the RX2 reduces drive weight. Even modest weight savings matter for wood-products haulers operating close to legal limits—extra payload over thousands of loads adds measurable revenue potential.
A Smarter Floor Configuration
The RX2 uses an 80% moving / 20% stationary slat layout, a design based on the Pareto Principle to maximize push force while minimizing drag.
This reduces hydraulic strain, improves energy efficiency, and contributes to longer floor life.
Cleaner Operation, Less Maintenance
RX Technology includes a high-flow filtration system that keeps oil cleaner and reduces contamination—a frequent issue in dusty lumber-mill environments.
The simplified hydraulic pathway contains fewer leak points and fewer parts overall, reducing both maintenance cost and time spent diagnosing issues.
For fleets with multiple trailers or high annual mileage, these design changes help reduce total cost of ownership substantially.
Operator Safety Through Intuitive Controls
WALKING FLOOR® systems are already a safer alternative to tipping trailers, especially on uneven mill yards or inside tight unloading bays. RX Technology enhances this advantage with more intuitive and predictable controls.
Key improvements include:
- Electric control architecture with optional manual override
- Single-action commands that simplify training and reduce operator error
These changes make the system easier for new drivers to learn and safer for all drivers to use.
CleenSweep® for a Faster, Cleaner Turnaround
For wood residuals—particularly chips, fines, and sawdust—cleanout can be a labor-intensive part of every load. KEITH recommends pairing the RX2 with its CleenSweep® tarp system, which automatically draws a tarp across the floor during unloading.
This dramatically reduces leftover material, improving safety and reducing time spent inside trailers.
In operations with tight turnaround schedules or contamination-sensitive materials, this pairing provides a significant efficiency advantage.
RX3: Higher-Capacity Power for Demanding Applications
While the RX2 will serve most chip and biomass haulers, the RX3 offers greater power and durability for higher-density loads or more demanding duty cycles, with its standard three-cylinder design.
Looking Ahead
RX Technology represents the beginning of a new era in KEITH’s WALKING FLOOR® engineering.
Rather than simply improving on the past, the RX platform redefines how reliability, safety, and performance are built into the system from the start.
For wood-products haulers facing rising demand, tight schedules, and increasingly complex operating environments, the RX2 delivers a practical and powerful solution: faster unloading, simpler maintenance, smarter controls, and greater long-term value. The RX Drive will be available October 2026.
