A single reach forklift is an electric-powered narrow aisle lift truck designed to retrieve pallets stored one position deep in racking systems . It is the most common type of reach truck and is widely used in warehouses, distribution centers, and manufacturing facilities to maximize vertical and horizontal storage density .
Key Function
Unlike a standard forklift that drives directly into the rack opening, a single reach truck utilizes a pantograph mechanism (scissor-like arms) that hydraulically extends the fork carriage forward. This allows the operator to place or retrieve a pallet from the first storage slot without moving the truck's heavy chassis .
Primary Applications
Single-Deep Racking: Ideal for warehouses that do not require double-deep storage (two pallets behind each other).
Narrow Aisles: Typically operates in aisles between 8 to 10 feet wide .
High Lifting: Often used in high-bay warehouses (lift heights up to 400 inches).
Specifications Overview (Typical Range)
Based on specifications from manufacturers like Crown and UniCarriers :

Lift Height Up to 400 inches
Load Center 24 inches
Power Source Electric (24V or 36V systems)
Tire Type Polyurethane Cushion (Indoor use only)
Aisle Width Approx. 8 – 10 ft
Comparison: Single vs. Double Reach
The primary difference between these trucks is the storage depth they can access .
Feature Single Reach Double Reach
Storage Depth 1 pallet deep 2 pallets deep
Fork Extension ~24 inches ~40+ inches
Aisle Width 8 - 10 ft 8 - 10 ft (similar)
Visibility Excellent (less complex arms) Reduced (blocked by arms)
Best For Fast cycle times, high turnover Maximizing storage volume
Operational Considerations
Surface: Single reach trucks are designed exclusively for smooth, indoor concrete floors and are not suitable for outdoor use, ramps, or uneven loading docks .
Advantages: Compared to double reach models, single reach trucks generally offer faster cycle times, simpler operation, and better visibility because the extendable arms do not obstruct the operator's view of the rack beams .
Environment: They are zero-emission electric vehicles, making them safe for cold storage and food-grade facilities.
