Between the standard APS AC walkie stacker and the counterbalanced ACS AC+EPS, the APS-15/18/20 AC+EPS delivers EPS power steering on the standard outrigger stacker platform — the combination that makes the most sense for operations where the outrigger design is preferred but operator steering fatigue has been identified as a problem.
In warehouse operations where stackers work continuous cycles — picking up loaded pallets, traveling to racking positions, lifting to height, returning — the cumulative steering input over an 8-10 hour shift on a conventional steering system creates real fatigue. By end of shift, steering precision decreases and operator attention to accurate placement reduces. EPS removes the physical resistance from the steering equation, allowing the operator to maintain precision and control consistently throughout the shift.
The AC motor provides the energy efficiency backbone: 30%-plus savings over DC, brushless reliability, and consistent performance in varying temperature conditions.
For operations that have standardized on outrigger stacker configurations but want to add EPS ergonomics — or that are building a new fleet and want to specify the highest operator-comfort platform within the outrigger stacker category — the APS AC+EPS is the appropriate choice. 100% Made in Taiwan.

• AC Motor + EPS Combination: Energy-efficient AC drive with electronic power-assisted steering — two upgrades that most directly affect operating cost (AC) and operator condition (EPS)
• EPS Power Steering: Significantly reduces the physical steering effort on a loaded stacker — consistent control throughout the shift, not just at the beginning
• Three Capacity Options: APS-15 (1.5T), APS-18 (1.8T), APS-20 (2.0T) — the capacity range where operator effort at steering is most noticeable in standard warehouse operation
• AC Energy Savings: 30%+ reduction in energy consumption vs. DC at comparable load weights
• Outrigger Stability: Standard outrigger configuration for stable lifting across pallet types
• Smooth Stepless Control: AC inverter provides proportional speed response; regenerative braking
• CE Certified: Made in Taiwan. ISO 9001. OEM/ODM available.

• High-cycle warehouse operations where operator steering fatigue has been identified
• Multi-hour picking and stacking operations in distribution centers
• Any outrigger stacker application where EPS ergonomics are prioritized
• Facilities with high operator turnover where ease of operation is a retention factor
• Cold storage where AC motor consistency and EPS control precision matter
Q1: Do I need EPS on a walkie stacker, or is it just a comfort feature?
A1: EPS on a walkie stacker is primarily an ergonomics and sustained-performance feature. In low-cycle operations with infrequent directional changes, the benefit is modest. In high-cycle operations — where an operator is making dozens or hundreds of steering inputs per hour over a full shift — EPS reduces the cumulative physical load significantly. The practical outcome is better operator condition at end of shift (reduced fatigue-related errors and safety incidents) and more consistent positioning precision throughout the day. Whether this justifies the additional investment depends on your cycle frequency and the demonstrated impact of operator fatigue in your specific operation.
Q2: What is the maximum lift height available on the APS-15/18/20 AC+EPS?
A2: Mast height options vary by configuration. Contact Noveltek with your required stacking height and bay depth for the appropriate mast specification on the APS-15/18/20 AC+EPS.
