Characteristics of through type shelves 1. Extremely high storage density: without independent access channels, forklifts can directly enter the shelves for storage, increasing storage capacity by more than 50% compared to ordinary shelves, suitable for scenarios with limited space and the need to store large goods in bulk. 2. Fixed access logic: Adopting the "first in, last out" mode, the inner goods need to be moved to the outer goods first, only suitable for small varieties and low turnover goods (such as seasonal stocking and unsold inventory). 3. Flexible equipment adaptation: No dedicated forklift is required, ordinary balance weight forklifts can operate, but attention should be paid to the safety of driving inside the shelves to avoid collision with structures. 4. Simplified structure and low cost: The shelf is composed of columns, beams, and guide rails, with a relatively simple structure and lower procurement and installation costs than narrow aisle and double depth shelves. 5. Stability dependent design: It is necessary to strengthen the overall rigidity of the shelf (such as installing top beams and back pull rods), and the goods should be evenly stacked to avoid deformation of the shelf caused by one-sided overweight.
