The characteristic is that the aisle is much  narrower than the general crossbeam type, about  1600mm-2000mm, which greatly improves the space  utilization rate of the warehouse. Today, with the  soaring house prices, narrow aisle shelves are favored  by many enterprise warehouses; The narrow lane shelf  needs to be equipped with a special forklift - three-way  stacking truck, which is another feature of it. Because  the channel is relatively narrow, this requires the skills  of the forklift driver. The driving skills should be more  skilled, and the work should be careful and cautious.  Secondly, after the installation of the narrow roadway  shelf, there is a guide rail with a height of about 100  mm (the guide rail can be made in the civil engineering, or the guard plate can be used when  installing the shelf) as the guiding system of the forklift,  which reduces the risk of the forklift driver to the shelf  due to human factors. Compared with the drive in type,  the requirements for the driver are lower
