Against the background that modern warehousing continues pursuing higher storage density, reach-type lithium-ion forklifts have become one of the most widely applied material handling equipment for indoor scenarios, thanks to their compact body structure and flexible high-lifting performance. The matching of lifting height and required aisle width is the core consideration in equipment selection and warehouse layout planning, unreasonable parameter matching will not only cause waste of storage space, but also bring hidden risks to daily operation and reduce overall handling efficiency.

First, the change of lifting height will directly affect the reasonable range of aisle width demand. For low lifting scenarios below 3 meters, the gantry structure of the forklift has small telescopic stroke and light self-weight, the center of gravity shift during operation is extremely limited, the required aisle width can be kept at a relatively compact level, which is very suitable for low-level shelf replenishment and fast material turnover scenarios. For medium lifting scenarios between 3 meters and 8 meters, the weight of multi-stage telescopic gantry increases synchronously, the overall center of gravity of the equipment shifts up slightly when the gantry is fully extended, and a small increase in the reserved aisle width can meet the stability demand of daily operation, which is the mainstream matching scheme for most conventional high-level storage scenarios. For lifting scenarios above 8 meters, the gantry structure has higher requirements for operation stability, and the aisle width needs to reserve enough safety margin to ensure that the operator can smoothly complete the steering, positioning and pick-and-place actions under the state of maximum lifting height.

Then, the pre-determined aisle width of the warehouse can also reversely deduce the maximum applicable lifting height range. Many warehouse operators will complete the shelf and access layout in advance during the renovation phase, and select the corresponding reach-type lithium-ion forklift according to the reserved aisle width. In this case, it is not appropriate to blindly pursue higher lifting height beyond the adaptation range of the existing aisle width, otherwise the safety gap in the steering process will be insufficient, and the anti-rollover safety threshold of the equipment will be reduced when lifting goods at a high position, which will affect the continuity and safety of operation. The lithium-ion power layout further optimizes the matching effect of the two parameters, the power battery can be reasonably integrated into the counterweight area of the body, no extra space for battery replacement is required, the overall size of the car body can be controlled more compactly, so that the required aisle width can be reduced appropriately under the same rated lifting height condition, helping to release more effective storage space.

In actual deployment, operators also need to combine the conventional pallet size, average load weight and the operation proficiency of on-site personnel to reserve a reasonable safety operation gap on the basis of nominal parameters of the equipment. Scientific and reasonable parameter matching can effectively improve the utilization rate of warehouse storage space, reduce the unnecessary loss of equipment in frequent operation, extend the service life of the whole vehicle, and finally reduce the long-term operation cost of the warehousing link.
