The “Jerk” Challenge in High Bays<\/h3>\n

The Netherlands serves as the logistics gateway to Europe, and its paper industry relies on some of the world’s most advanced Automated Storage and Retrieval Systems (AS\/RS). In the distribution centers of **Venlo**, **Tilburg**, and the **Maasvlakte**, stacker cranes lift paper rolls weighing 5 tons to heights of 40 meters. The drive shafts connecting the lift motors and travel bogeys operate in a realm of extreme dynamics: rapid acceleration curves (high “Jerk” values), regenerative braking, and precise servo-positioning.<\/p>\n

Standard industrial shafts act as torsional springs. Under high acceleration (up to 4 m\/s\u00b2), they twist (wind-up) and then release, causing “Mast Whip” or oscillation at the crane tip. This vibration forces the AS\/RS control system to wait for stabilization before extending the forks, killing cycle time efficiency. Furthermore, the backlash in standard splines leads to positioning errors, causing system faults when engaging the pallet or roll.<\/p>\n<\/div>\n

\n

The Ever-Power “Logi-Sync” Solution<\/h3>\n

Ever-Power has developed the **Logi-Sync\u2122 Series** to serve the high-throughput demands of the Dutch intralogistics sector. We utilize **Composite Tube Technology** (Carbon Fiber Filament Winding) for vertical lift shafts to reduce rotational inertia by up to 60%. This allows for faster acceleration with less motor torque.<\/p>\n

To address positioning accuracy, we employ **Zero-Backlash Hirth Flanges** and pre-loaded ball-spline or nylon-coated spline mechanisms. This ensures a rigid link between the servo motor encoder and the load, eliminating the “dead band” in the control loop. Compliance with **NEN-EN 528** (Rail dependent storage and retrieval equipment safety) ensures that our shafts meet the rigorous safety protocols required for automated machinery in the EU.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Systemic Synergy: Precision Gearboxes<\/h3>\n

In an AS\/RS stacker crane, the drive shaft is the conduit between the servo motor’s precision and the wheel block’s motion. If the gearbox has backlash or the shaft has inertia lag, the crane will overshoot its target. We recommend pairing our **Logi-Sync Shafts** with **Ever-Power Planetary or Servo-Worm Gearboxes**.<\/p>\n

Our gearboxes feature low-backlash gearing (< 3 arcmin) and high radial load capacity output bearings to handle the weight of the crane mast. For the Dutch market, we offer “Harmonic Drive Tuning” \u2013 ensuring the complete drivetrain does not resonate with the racking structure frequency.<\/p>\n

Case Study: Venlo Logistics Park<\/span><\/p>\n

Damping “Mast Whip” at 35 Meters<\/h3>\n

The Challenge:<\/strong> A newly automated paper roll warehouse in Venlo was struggling with cycle times. Their 35-meter tall stacker cranes experienced severe mast oscillation (whip) after rapid deceleration, forcing the system to wait 3 seconds before extending forks. The culprit was identified as “torsional wind-up” in the 6-meter long vertical steel drive shafts.<\/p>\n

The Ever-Power Solution:<\/strong> We retrofitted the cranes with AS-Robo 350 Composite Shafts<\/em>. The Carbon Fiber tube increased torsional stiffness by 40% while reducing rotational inertia by 55%. We also upgraded to zero-backlash clamping hubs.<\/p>\n

The Impact:<\/strong> Mast settling time was reduced to near zero. The cranes could accelerate harder (from 2.5 to 3.5 m\/s\u00b2) without inducing sway. Throughput increased by 18%, allowing the facility to handle peak season volume without adding shifts.<\/p>\n<\/div>\n

Expert Insights: FAQ for Dutch Logistics Engineers<\/h3>\n
\n

How can I reduce sway in my AS\/RS stacker crane?<\/h4>\n
\n

Sway (mast oscillation) is often exacerbated by drive shaft wind-up. To reduce it, you must increase the Torsional Stiffness of the drivetrain. We recommend switching to **Composite (Carbon Fiber) Drive Shafts** or large-diameter steel tubes. This stiffness ensures the wheel movement instantly follows the motor command, allowing the PLC’s anti-sway algorithms to work correctly.<\/p>\n<\/div>\n<\/div>\n

\n

What is the delivery time for a replacement shaft to a warehouse in Tilburg?<\/h4>\n
\n

We know that warehouse uptime is non-negotiable. For standard industrial sizes, we can manufacture and air-freight a balanced, painted shaft to Tilburg or Eindhoven within 3-4 weeks. For emergency breakdowns, we offer a 10-day priority manufacturing service.<\/p>\n<\/div>\n<\/div>\n

\n

How do you handle the high acceleration forces (4G) in modern stackers?<\/h4>\n
\n

High acceleration creates massive peak torque loads. We design our **AS-Robo Shafts** with a peak torque capacity of 3.0x nominal torque. We use **Hirth Serration Flanges** or **Clamping Hubs** instead of keyed connections, as keys tend to shear or wallow out under high-jerk cyclic loading.<\/p>\n<\/div>\n<\/div>\n

\n

Are your components compatible with NEN-EN 528 safety standards?<\/h4>\n
\n

Yes. Ever-Power drive shafts are engineered to meet the requirements of **NEN-EN 528 (Rail dependent storage and retrieval equipment)**. We provide full material traceability, fatigue analysis reports, and balancing certificates to support your system’s safety documentation.<\/p>\n<\/div>\n<\/div>\n
