Choose to use push-back racking (push-back racking) generally consider the following five issues:
(1) Warehouse structure: When selecting push-back racking, it is necessary to consider the available operational storage space of the warehouse and the useful height of the highest beam in the shelf structure to determine the height of the shelf. It is necessary to know the beams and columns of the warehouse. The orientation will also affect the equipment and layout of the shelves. The bearing capacity and flatness of the warehouse floor are also related to the planning and installation of the shelves. The layout of fire protection equipment and lighting equipment also needs to be considered;
(2) Item characteristics (scale, weight, storage number, storage unit, etc.): It is useful to handle the unitized operation of stored items, which has a great impact on the precise definition of shelf structure and storage operations, that is, the shape and size of the stored items. The scale is directly related to the selection of the shelf standard; the weight of the stored items directly affects the type and method of the strength, stiffness and stability of the shelf; also to estimate the total number of storage spaces, it is necessary to consider the enterprise Growth needs in the next two years, etc.
(3) Accessibility (storage density, first-in, first-out, storage location management): Generally, accessibility and storage density are relative. In order to obtain a higher storage density, it is necessary to sacrifice the accessibility of items. Although push-back racking can achieve better storage density, it is more complicated than its storage location management, and it is often impossible to achieve first-in, first-out management.
(4) Handling equipment (counterweight type, straddle type, aisle width, lifting height, lifting component, rotation radius): The access operation of storage equipment is completed by transfer equipment. Therefore, the selection of push-back racking needs to consider the equipment of the transfer equipment at the same time.
(5) In-out volume (first-in, first-out, access frequency, access quantity): Although push-back racking has a good storage density, the in-out volume and operation efficiency are not high, suitable for for low frequency work. It is necessary to combine other methods of shelf structure, operation area management, storage location management and other methods to deal with items with high in-out volume.
In a word, the type, size, connection and structure of the push-back racking structure should be based on the type, quantity, size, access frequency of the goods and the application requirements of the type, type, performance and control method of the storage and transportation machinery. , determined by inductive comparative analysis. The operating end of the forklift has a certain horizontal force on the push-back trolley. The particularity of the horizontal force should be considered in the planning and selection of the rack structure, and the column should be securely anchored to the foundation.
What to pay attention to when buying press-fit racks
1. Choose a press-fit rack manufacturer prudently
The production accuracy of the press-in rack is relatively high, and the cooperation between the pallet trolley and the guide rail is particularly important. If the production and installation accuracy is not high, it is very easy to cause the poor operation of the racking system;
2. The depth of the cargo space is limited
In the push-in rack, the total depth of the single-layer rack should not be too deep. Generally speaking, it should not exceed the depth of 5 pallets. Otherwise, the space will be wasted greatly because the pallet trolleys are embedded and superimposed.
3. The total height of the shelf should not be too high
Because there is a slope difference between the front and rear of the shelf, and the single-layer pallet trolley is automatically embedded and superimposed at the front end, the height needs to be within the range of 6m, otherwise, the high forklift will cause the operation of the forklift to be higher;
4. Assess the shelf cost
Because of the special use of the push-in rack, the precision and flexibility of the push-in rack are required to be high, which will lead to a high investment and construction cost of the push-in rack. Therefore, it is necessary to evaluate the investment and applicability of the cost-effective return. consider.
