Advantages: When the push back rack accesses goods, the forklift only works on the lower end of the guide rail, and there is no need to enter the goods storage channel of the rack, so that the access speed is higher than that of the drive-in rack. This feature makes it suitable for use as a temporary storage area in the warehouse, and it is also very suitable for customers who have limited warehouse space but want to achieve intensive storage in a small area. 3 to 4 deep locations. The structure of the push back rack is relatively stable, and the requirements for the forklift operator are lower, which can reduce the probability of misoperation hitting the rack.

Technical difficulties and disadvantages: The push back rack needs to use a pallet trolley to carry the goods, which involves the cooperation between different levels of trolleys, between trolleys and guide rails, and between guide rails and shelves. The greater the storage depth, the greater the design difficulty. The shelf production precision is very high, the cost is high, and limited by the structural characteristics of the shelf, the depth of the cargo space is generally not more than 5, and the storage rate is relatively low among the intensive storage shelves.
