Engineered for the High-Stakes Construction Sector of the Netherlands.
Zero-Failure Transmission for Split-Shaft PTOs, ensuring continuous pouring capability for Putzmeister, Schwing, and Cifa fleets.
The Heartbeat of the Concrete Fleet: Why Transmission Matters
In the Netherlands, the construction industry faces unique challenges. From the massive “Ruimte voor de Rivier” water management projects to the deep-foundation skyscrapers in the Zuidas district of Amsterdam, concrete pouring is a precision operation that permits no interruptions. Once a pour begins, the concrete pump truck becomes the most critical asset on site. If the main hydraulic pump stops due to a drive shaft failure, the concrete in the boom hardens within hours, leading to tens of thousands of Euros in damage and project delays.
The Main Hydraulic Pump Drive Shaft is the mechanical link between the truck’s engine (via the Transfer Case/Split-Shaft PTO) and the hydraulic pumps that drive the concrete cylinders. Unlike a standard automotive prop shaft, this component operates at maximum torque while the truck is stationary, often at steep angles depending on the chassis flex and outrigger setup. It must endure the punishing “Shock Loads” generated every time the S-valve switches direction, a cycle repeated thousands of times per day.
Torsional Vibration Damping
Direct diesel drive creates harmonic vibrations. Our shafts feature computer-optimized tube thickness and optional rubber-element couplings to dampen the torsional spikes before they reach the delicate hydraulic pump swashplates, extending pump life.
High-Angle Reliability
Mobile pump trucks often operate on uneven ground (polder clay or construction rubble). Our high-articulation Universal Joints allow for continuous operation at angles up to 25 degrees without binding or overheating, utilizing premium needle bearing technology.
Continuous Duty Cycle
A massive pour in Rotterdam can last 48 hours non-stop. Standard agricultural shafts will melt under this heat load. EVER-POWER shafts use high-temperature Lithium Complex grease and Viton seals to withstand continuous high-speed rotation.
Engineering for the “Split-Shaft” Environment
The drive train of a modern concrete pump truck (e.g., Mercedes-Benz Arocs or MAN TGS chassis) is a marvel of engineering. The power from the main engine is diverted via a Split-Shaft PTO. The drive shaft connected to this PTO transmits 100% of the engine’s available torque to the hydraulic pumps.
This application demands a drive shaft with an exceptional Service Factor (SF > 1.8). Standard shafts made from generic steel often fail at the spline connection due to “Fretting Corrosion”—a wear pattern caused by micro-movements under high torque. EVER-POWER solves this by utilizing 42CrMo4 (Chromium-Molybdenum) Steel for all yokes and spline components, followed by a proprietary Gas Nitriding process. This creates a surface hardness that resists fretting, ensuring the telescoping movement remains smooth even after years of service.

Custom Manufacturing: Rapid Response for Breakdowns
We understand that a concrete pump truck is a revenue-generating asset only when it is pumping. Waiting weeks for an OEM replacement shaft from Germany or Italy is often not an option for Dutch fleet operators. EVER-POWER offers a “Made-to-Measure” service.
Our manufacturing facility is equipped with specialized long-bed CNC lathes and dynamic balancing machines capable of handling shafts up to 3 meters long. If you have a breakdown, we can manufacture a custom shaft based on your compressed length and flange measurements. We stock standard flange yokes (DIN, SAE, Mechanics) and cross kits, allowing us to assemble and balance a replacement shaft within days, not weeks.
Precision Balancing
Every shaft connects to a high-speed hydraulic pump. Imbalance causes pump seal failure. We balance every CPT-series shaft at 3,000 RPM to ensure vibration-free operation.
Retrofit Upgrades
Replacing an undersized OEM shaft? We can engineer an “Upgrade Kit” that fits the same space but offers 30% higher torque capacity for extended lifespan.
Case Study: 48-Hour Continuous Pour in Utrecht
The Challenge
A leading Dutch concrete logistics company was contracted for a massive foundation pour for a new data center near Utrecht. The project required continuous pumping for 48 hours. During a pre-project test, one of their 56-meter boom pumps exhibited severe vibration in the main hydraulic line. The OEM drive shaft splines were worn, creating backlash that threatened to destroy the main hydraulic pumps.
The EVER-POWER Solution
With only 3 days before the pour, the client contacted EVER-POWER. We identified the issue as “Spline Galling” due to lack of lubrication in the original design. We manufactured a custom Heavy-Duty Series 7 Shaft featuring a Rilsan-coated spline (permanently lubricated) and an upgraded 180mm flange interface.
The Outcome
The shaft was air-freighted and installed within 48 hours. The pump truck performed flawlessly throughout the marathon pour, handling over 2,500 cubic meters of concrete without a single vibration issue. The fleet manager has since standardized EVER-POWER shafts for their entire 40+ truck fleet.
