Reach Truck
A warehouse truck whose mast or fork carriage extends to retrieve goods and retracts for stable travel in narrow aisles and high racking.
Definition
A reach truck extends its mast or carriage along support legs to pick up loads, then retracts the load into the support area for travel. This combines compact dimensions with high-rack access without a large rear counterweight. It is a common electric truck in high-bay warehouses, with some models lifting beyond ten metres.
How the Reach Mechanism Supports Stability
Support legs keep travel loads within the support area but can obstruct direct rack access. Extending the mast while stationary reaches beyond the legs; retracting it brings the load back for travel. This changes the centre of gravity between working phases and allows high storage access in relatively narrow aisles.
Comparison with Counterbalance Trucks
Reach trucks reduce aisle width and increase storage density. Their legs need compatible pallets and rack bases, while high lift demands level floors. They are less suited to frequent trailer access and outdoor travel. Warehouses often combine reach trucks for rack work with counterbalance trucks for docks and transfers.
High-Level Handling Challenges
Mast sway after stopping or impact needs time to settle before fork insertion. High loads make direct alignment difficult; height preselection, fork cameras or laser aids can help. Small floor differences become large offsets at height. Verify remaining capacity at both the actual lift height and load centre.
Maintenance Priorities
Reach rails and rollers can wear, causing sticking, noise or vibration. Cylinder seals can cause weak reach, slow lift or fork drift. Inspect mast rollers, lubrication and equal chain tension. Functionally test height detection and speed interlocks, whose failure may otherwise remain unnoticed.
Coordinate Truck and Warehouse Design
Plan rack levels and required lift first, then collapsed-mast and ceiling clearances, working aisles and support-leg access. Verify high-level payload and floor flatness. Include floor improvements when needed; selecting a truck independently of racking and floor conditions often causes rework.
Frequently Asked Questions
How can a reach truck lift high in a narrow aisle?
It extends for stationary load access and retracts the load between its support legs for travel, avoiding the space needed for a large counterweight.
What does the warehouse need?
Compatible rack and pallet clearance for the legs, sufficiently level floors and aisles sized to the model's right-angle stacking requirement.
