In elevated warehouses with intensive storage technology, the channel width is compressed to extremely narrow, which puts forward extremely stringent requirements for the selection of stackers and pallet trucks operating in this environment, and it also makes the formulation of traffic safety regulations essential.The primary core criterion for selection is the “passability” size of the vehicle, especially the total width of the body and the minimum turning radius.Dedicated narrow-channel forklifts (VNA) or reach trucks are the mainstream choice for such environments. They are characterized by moving the gantry forward or the fork forward to pick up and place the goods, without the need for the vehicle to turn into the deep position of the shelf as a whole, so the channel width requirements are much smaller than traditional counterbalanced forklifts.For pure plane handling, ultra-low-body electric pallet trucks (including with side-shift function) are the basis for ensuring flexible shuttling in small spaces.When selecting the model, it must be strictly calculated based on the actual width of the channel in the warehouse design drawings and the technical parameters of the selected model to ensure that there is sufficient safety margin.

In addition to the model, some specific functions of the vehicle are also essential for narrow-channel operations.The side shift function is almost necessary. It allows fine-tuning of the fork position to accurately align the cargo position and compensate for the vehicle positioning deviation caused by the narrow passage.Height-adjustable forks or door frames help to operate under limited headroom.For narrow-channel forklifts with rail guidance, the accuracy and reliability of the guidance system are the key.In addition, the vehicle should have a good field of vision. Whether it is through the design of the door frame to reduce the blind spot in the field of vision, or with the help of auxiliary observation methods such as cameras, it is necessary to ensure that the operator has a clear perception of the surrounding environment in a narrow space. .

Due to the highly restricted working space, any mistakes may cause serious damage to shelves, goods or equipment. Therefore, the formulation and strict implementation of a set of strict traffic and operation safety regulations is the lifeline.The specification should clearly stipulate: the maximum driving speed of the vehicle in the passage, especially when turning and approaching the shelf, must be slow and slow.Formulate clear driving routes to avoid cross-operation, and one-way streets can be set up if necessary.It is emphasized that when accessing the goods, it is necessary to ensure that the vehicle is completely parked and the fork is aligned with the cargo space before operating. It is strictly prohibited to lift or adjust the goods while driving.The operator is required to always closely observe the obstacles above and on both sides of the passage, especially fire-fighting pipes, lighting facilities and shelf beams.Regularly check the flatness of the channel floor and remove any debris that may trip the wheels.At the same time, there must also be clear warnings and avoidance regulations for pedestrians entering the narrow passage area.Through the combination of scientific selection and iron law-like safety regulations, it is possible to maximize the use of storage space while ensuring efficient and safe operations in narrow passages.
