The RSS Series: Engineering Meets Efficiency
Redway’s RSS straddle stackers redefine spatial efficiency in warehouses through three tailored models: the RSS 22 (2,200 lbs capacity), RSS 30 (3,000 lbs), and RSS 40 (4,000 lbs). Unlike bulkier alternatives, these units combine a 124″ maximum lift height with a razor-thin 27–51″ adjustable straddle width, enabling operators to maneuver through aisles narrower than a standard parking space. The series’ 4.3 mph travel speed and 47″ turning radius outperform traditional stackers by 15–30%, allowing teams to reposition pallets in tight urban warehouses without sacrificing productivity.
| Model | Load Capacity | Lift Height | Key Advantage |
|---|---|---|---|
| RSS 22 | 2,200 lbs | 124″ | Cold storage optimization |
| RSS 30 | 3,000 lbs | 124″ | Dual-stage mast stability |
| RSS 40 | 4,000 lbs | 124″ | Heavy-duty production line use |
Operators praise the intuitive digital dashboard that displays real-time diagnostics—from remaining battery life to maintenance alerts. During a recent automotive parts distributor trial, the RSS 30 reduced pallet retrieval times by 22% through its Turbo Mode, which temporarily boosts lifting speeds for urgent tasks without compromising energy efficiency.
Safety: Where Innovation Meets OSHA Compliance
The RSS series embeds six layers of proactive safety features:
- Auto-Braking System: Uses inertial sensors to prevent load shifts during abrupt stops
- Smart Load Sensors: Disable lifting at 105% capacity thresholds
- Blue-tooth® Stability Monitors: Sync with warehouse safety systems to geofence hazardous zones
- Diamond-Tread Platforms: Reduce slip incidents by 34% in wet conditions
- Pressure-Sensitive Straddle Legs: Auto-adjust on uneven surfaces down to -20°F
- Regenerative Braking: Converts descent energy into battery recharge cycles
These features proved critical for a Midwest frozen foods warehouse, where the RSS 22’s cold-optimized components reduced downtime by 40% compared to previous LPG-powered models.
Industry-Specific Adaptations
Redway’s modular design philosophy allows the RSS stackers to serve niche applications:
- Pharmaceuticals: Non-marking polyurethane tires prevent contamination
- Chemicals: Corrosion-resistant mast coatings withstand acidic environments
- E-Commerce: IoT integration enables real-time synchronization with warehouse management systems (WMS)
