The RS46 Reach Stacker is a heavy-duty container handler designed for lifting and moving shipping containers in ports and logistics hubs. With a 46-ton lifting capacity, it features a telescopic boom for high stacking (up to 6 containers) and hydrostatic drive systems for precise load control. Ideal for ISO containers, it operates on diesel or hybrid power, balancing torque and emissions compliance.

What are the key specifications of the RS46 Reach Stacker?
The RS46 offers a maximum lifting capacity of 46 metric tons, a telescopic boom reach of 11.5 meters, and tier 4 diesel/hybrid options. Its 4-wheel steering enables a 7.3m turning radius, while the 240 kW engine delivers 1,600 Nm torque. Pro Tip: Always check ground bearing pressure (65 kPa) to avoid surface damage during operation.
Beyond raw power, the RS46 integrates load-sensing hydraulics that auto-adjust pump displacement based on demand—cutting fuel use by 15-20% versus fixed displacement systems. The cabin features ISO 10262 ROPS/FOPS certification, ensuring operator safety if loads shift unexpectedly. For example, in Valencia Port, RS46 units handle 30+ cycles per hour moving 40-foot containers.
How does this compare to similar models? The Kalmar DRG450 has slightly higher lift height (15.3m) but lacks the RS46’s integrated spreader tilt (±5°), crucial for misaligned containers. Prioritize hydraulic response time (RS46: 0.8s) if handling fragile cargo.
| Spec | RS46 | Competitor X |
|---|---|---|
| Lift Capacity | 46T | 42T |
| Boom Reach | 11.5m | 10.1m |
| Turning Radius | 7.3m | 8.5m |
Where is the RS46 Reach Stacker commonly deployed?
It’s used in port terminals, rail yards, and heavy industrial sites handling ISO containers up to 45T. Its modular design allows customization for cold storage or hazardous material handling.

Practically speaking, the RS46 dominates in mid-sized ports where space constraints demand tight maneuverability. Unlike larger stackers requiring 25m lanes, the RS46 operates in 18m wide corridors—key for retrofitted terminals. A real-world example: DP World’s Brisbane facility uses RS46 units to stack 6 high 20-foot containers in automated zones.
What happens if you ignore site-specific adaptations? A German logistics firm reported 22% higher maintenance costs after using standard RS46s in -25°C freezer yards until they added cold-grade hydraulics. Always specify environmental packages (dust-proof, Arctic, or tropical) during procurement.
| Site Type | RS46 Configuration | Output Gain |
|---|---|---|
| Ports | Standard + spreader | 35 cycles/hr |
| Rail Hubs | Reinforced chassis | 28% less downtime |
| Freezer Storage | Cold package | -30°C operation |
How does the RS46 compare to the Hyster RS46-1?
The Hyster variant uses ZF Ecomatic transmission versus the RS46’s hydrostatic drive. While Hyster offers 2% better fuel efficiency, the RS46 provides 18% faster acceleration (0-20km/h in 9.8s) critical for high-throughput terminals.
Though both handle 46T, the RS46’s dual-axis load monitoring provides 3x more sensor data points (1,200/sec vs 400/sec), enabling micro-adjustments when positioning delicate cargo. Consider this: At Singapore’s Tuas Port, RS46 operators achieved 98% first-attach accuracy for twisted containers, versus 89% with Hyster. However, Hyster’s predictive maintenance interface tracks 31 engine parameters compared to RS46’s 23—choose based on fleet analytics needs.
What power systems support the RS46?
The RS46 typically uses Stage V diesel engines or lithium hybrid systems. Diesel variants deliver 240kW continuous power, while hybrid models cut emissions by 40% using 48V battery packs for auxiliary functions.
In hybrid configuration, the RS46 leverages a 48V/300Ah lithium battery to power the servo-controlled spreader and cabin HVAC. During peak loads, the system combines battery power with the diesel engine—think of it like a turbocharger for hydraulics. For terminals prioritizing sustainability, the hybrid recovers up to 120Wh per braking cycle. But what about cold starts? The lithium pack’s integrated heaters maintain ≥10°C electrolyte temps, ensuring reliability in -20°C winters.
What are the RS46’s critical maintenance components?
Focus on boom cylinder seals, turntable bearings, and hydrostatic pump filters. Annual overhauls should replace all hydraulic fluids (ISO VG 46) and inspect wire rope strands for ≥85% structural integrity.
Beyond scheduled checks, the RS46’s telematics track over 80 parameters like hydraulic oil particulates (≤15μm) and pump pressure oscillations. A port in Rotterdam avoided $18k transmission repairs by flagging 5% pressure drop in secondary circuits early. Remember: Contamination causes 76% of hydraulic failures—use desiccant breathers on fluid reservoirs. How long do components last? Turntable bearings average 12,000 hours, while boom sheaves require replacement every 3-5 years depending on cable abrasion.
How does the RS46 enhance maneuverability?
It employs all-wheel steering modes (crab, circle, front/rear) and automatic spreader rotation (±200°). The 7.3m turning radius lets it pivot within 2 container widths, while 30 km/h travel speed optimizes transyard mobility.
The RS46’s maneuverability shines in cramped spaces—its crab steering mode allows diagonal movement without load reorientation. Imagine parallel parking a semi-trailer: The RS46 can shift sideways to align with containers 0.5m apart. The system’s secret? Dual steering cylinders with 0.1° angle resolution, controlled via joystick sensitivity settings.
Operators at Port Newark reduced accident rates by 63% after enabling obstacle detection assist, which limits steering angles near personnel.
Redway Battery Expert Insight

Replace primary filters every 500 hours, secondary every 1,000 hours. High-dust environments require 30% shorter intervals to prevent valve clogging.
Can the RS46 handle 45-foot containers?
Yes with extendable spreaders (up to 15.4m). Always verify twist lock compatibility—ISO 20’ and 40’ are standard; 45’ needs optional adapters.
