As modern warehouse operations continue to pursue optimized space utilization, deep racking systems have become a common layout choice to expand storage capacity without expanding the existing facility footprint. Reach trucks, as core narrow-aisle material handling equipment, are widely adopted in such scenarios, while standard reach truck and double-reach truck have different performance boundaries that directly affect the final storage density of the whole facility.

The standard reach truck features a mast that can extend forward for a limited distance, which is designed to access single-depth racks set close along both sides of the operating aisle. It requires relatively narrow aisle width, brings smooth and flexible operation experience for operators, and supports high-frequency inbound and outbound operations with stable load handling performance. For warehouses that arrange racks no more than one row deep on each side of the aisle, this model can fully meet daily operation demands, and adapt to most common ground conditions of existing warehouse sites. It also has relatively low learning threshold for new operators, which helps reduce personnel training cost in long-term operation.

The double-reach truck is developed for scenarios that demand higher storage density. Its specially designed extending structure allows the mast to reach through the front row of racks and access the second row of deep racks behind, so that each aisle can serve two rows of racks on each side directly. With this layout, the total storage capacity of the same warehouse space can get a noticeable lift, which makes it a cost-effective option for operators who need to maximize storage volume without making large modifications to the existing building structure. It is worth noting that this model has higher requirements for ground flatness and rack alignment accuracy to ensure operation safety, and the pre-operation site check process needs to be more rigorous.

When making selection decisions, warehouse operators need to combine multiple practical factors rather than blindly pursue the highest possible storage density. For scenarios with high SKU turnover rate, small single-SKU stock volume and high requirements for picking efficiency, the standard reach truck can bring more convenient operation flow and lower operation error rate. For scenarios with medium or low SKU turnover rate, large batch storage demand and limited budget for site reconstruction, the double-reach truck can achieve a good balance between storage density and operation efficiency. Operators can also simulate their own daily operation flow with device suppliers before finalizing the configuration, to get the most suitable solution matching actual business demands.
