Very Narrow Aisle Trucks
Trucks that work in aisles under 1.7 m by turning the forks instead of the chassis, letting racking be pushed closer together. Always fitted to a guided aisle and specified together with the rack layout.
Features
- A turret or swing-reach head rotates the forks 180 degrees, or 90 degrees each way, so the truck stays square in the aisle and never needs room to turn.
- Man-up versions lift the operator with the forks for picking and put-away at height; man-down versions keep the operator at floor level and are simpler to maintain.
- Needs either floor-mounted guide rails or an inductive wire in the slab. Both fix the aisle position permanently.
- Mast heights beyond 12 m are normal in this class, which puts load-chart derating and slab flatness at the centre of the specification.
- Because the aisle is guided, in-aisle travel speed can be set higher than on a free-ranging truck of the same height.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Rated capacity | 1 000 - 1 500 | kg | derates sharply towards full height |
| Maximum lift height | 6 000 - 14 500 | mm | the top beam it can serve |
| Minimum aisle width | 1 650 - 1 900 | mm | the figure that justifies the truck |
| Guidance type | rail / inductive wire | determines slab work before delivery | |
| Fork rotation | 180 or 90 + 90 | degrees | single- or double-sided picking |
| Floor flatness requirement | superflat / defined-movement class | mast sway at height depends on it | |
| Battery voltage | 48 / 80 | V | with capacity, sets shift endurance |
