In material handling engineering, selecting the right actuation method determines the long-term reliability, precision, and safety of plant floor operations. Traditional vertical lift systems frequently rely on pneumatic cylinders, which are highly susceptible to pressure drops and air leaks. The RZR Rack distributed by NSMC utilizes advanced electromechanical linear actuator technology to mechanically expand upward. This design provides an efficient, self-contained solution for high-density automotive dunnage deployment without the operational drawbacks of facility compressed air lines.
Pneumatic cylinders require extensive facility plumbing and continuous compressor power, which limits line-side portability and increases maintenance overhead. By contrast, the RZR electromechanical system converts electrical energy directly into stable linear motion, offering a highly controlled alternative for modern manufacturing floors:
• Button-Triggered Control:
The automated dunnage system raises and lowers effortlessly at the touch of a button, removing manual lifting requirements.
• Elimination of Structural Waste:
The vertical expansion automatically provides increased storage capacity exactly when required.
• Dead Air Space Mitigation:
This dynamic configuration eliminates dead air space and drops the need for secondary, standalone storage racks.
• Zero Routine Maintenance:
The closed-loop mechanical lift framework is engineered to remain completely maintenance-free throughout its lifecycle.
• High-Strength Construction:
Every unit is manufactured in the USA using high-strength, durable industrial components.
The lifting mechanics of the RZR adjustable dunnage rack are driven by a heavy-duty electromechanical system built to withstand continuous, multi-shift plant workloads.
According to the official system documentation, the baseline performance criteria adhere to the following precise engineering values:
| Performance Parameter | Technical Rating Metric |
Technical Rating Imperial |
|---|---|---|
| Voltage Requirement | 24 V DC | 24 V DC |
| Maximum Load Capacity (Push) | 6,000 N | 1,348 lbs. |
| Maximum Load Capacity (Pull) | 4,000 N | 899 lbs. |
| Maximum Speed at Full Load | 23.4 mm/s (with 1,000 N load) | 0.921 in/s (with 224 lbs load) |
| Mechanical Stroke Length | 635 mm | 25 in |
| Operational Temperature Range | +5°C to +45°C | +41°F to +113°F |
| Regulatory Compliance Certifications | EMC and RoHS compliant | EMC and RoHS compliant |
To accommodate a broad range of automotive component payloads, the actuator's 3400 RPM motor (operating at a 10% duty cycle) can be specified across multiple load codes:
• Code L (Maximum Load Capacity):
Rated for a 6,000 N push and 4,000 N pull vector. It features a self-locking force of 4,000 N and draws a 4.2 A current under load, yielding a full-load velocity of 4.1 mm/s.
• Code N (Balanced Performance):
Rated for a 2,500 N push and 2,500 N pull vector. It provides a self-locking force of 1,500 N and draws a 4.1 A current under load to reach a speed of 11.1 mm/s.
• Code P (High-Speed Extraction):
Rated for a 1,000 N push and 1,000 N pull vector. It features a self-locking force of 500 N and draws a 3.0 A current under load to achieve a rapid full-load velocity of 23.4 mm/s.
• Code T (Heavy-Duty Intermediate):
Rated for a 5,000 N push and 4,000 N pull vector. It provides a self-locking force of 2,500 N and draws a 4.2 A current under load, operating at a full-load speed of 5.4 mm/s.
Unlike pneumatic systems that permanently tie machinery to fixed facility air drops, electromechanical bag rack frames support modular power and control options:
• External Control Units:
This stationary, line-side power unit requires an external 120-volt power supply. To maximize workplace safety, it features a control configuration that requires two hands for operation. Exactly one unit is required per station.
• Control Carrying Cases:
This interface provides mobile power capabilities and is designed to go comfortably over an operator's shoulder or directly onto their belt. It requires a portable 24-volt battery connection, with one unit required per station.
• Built-In 24-Volt Battery Units:
This self-contained option integrates a removable and rechargeable battery module directly into the rack frame. Each assembly includes a heavy-duty protective housing, a directional switch, and requires one unit per rack.
• Industrial Rocker Switches:
Utilizing a compact 2" x 1" footprint, this 30A 12VDC component delivers precise two-directional control and can be mounted directly to the rack or to external power boxes.
• Kobalt Lithium-Ion Power Packs:
Racks utilize high-performance 24-volt max Li-ion batteries equipped with built-in power indicators and internal circuitry to protect against over-charge, over-discharge, and extreme temperatures. Racks incorporate 2.0 Ah battery packs for integrated setups (recharging in 30 minutes) and 4.0 Ah variants for external carrying cases (recharging in 1 hour).
The mechanical durability of the RZR platform is backed by a structured factory warranty program and rigid operational boundaries to eliminate material handling hazards.
