Detailed Description:

1. Brief Introduction

Push-back racks, also known as drive-in racks — consist of multiple levels of carts overlapping between the front and back beams. Goods are stacked on the carts from the outside and pushed in. Stored items at the back will push the earlier items inward.

2. Application

1. Forklift access.

2. Ideal for items with a limited variety and large quantities, utilizing a first-in, first-out operational method.

3. Ideal for situations requiring a significant increase in space utilization, such as refrigerated warehouses. 

3. Shelf Features

1. The push-in shelving is composed of typical structural components such as trolley carts, which feature mobility. Goods are loaded and unloaded at one end of the racks following the first-in, first-out principle.

2. When handling goods for storage and transportation, the forklift operates only at the lower end of the shelf aisle, without entering the storage channels between the shelves. Such racks are characterized by high storage density and fast handling speeds.

3. Typically used in situations where storage space is limited but additional storage capacity is required or there are time constraints on the goods, with minimal selection requirements for the products.
