Introduction
LTV Steel has chosen a Very Narrow Aisle (VNA) lift truck for optimal cube utilization in their revamped storage facility for large crane components and replacement parts.

Specifications
The facility features a 12-aisle, 400-ft long, 20-ft high storage system designed for variable load openings. The Drexel SwingMast SL-120, with a 12,000 lb capacity, is the largest VNA lift truck delivered to the commercial market by Drexel.

Features
The SL-120 includes a 90° pivot, 44-in. shift, automatic return-to-neutral, separate GE controls for traction and pump motors, a battery discharge indicator with lift interrupt, hydrostatic power steering, and polyurethane tires. It has a three-stage mast allowing lift heights of 243 inches and mast tilt of 3° forward and 6° rear.

Operational Insights
The truck operates on twin 36-volt batteries, providing a full 8-hour shift. It requires trained operators for optimal performance.

Conclusion
The VNA configuration and the SL-120 lift truck enhance storage efficiency, achieving approximately 65% cube utilization compared to the typical 50% in most warehouses.
