What is Press Fit Racking? What are the similarities and differences between press in racks and grav

Cantilever shelves are mainly composed of column pieces, cantilever beams, connecting rods, etc., which are characterized by the cantilever structure of the front extension is lightweight, the load is strong, and the storage of non-standard or long rod materials, can greatly improve the utilization rate and work efficiency of the warehouse, the cantilever shelves are divided into single arm and double arm, and are suitable for storing long materials, ring materials, plates, pipes and irregular goods. The cantilever shelf column is welded by two pieces of cold-rolled C-shaped profile face-to-face, and there are double rows of holes punched on the column, and the hole pitch is 140 (50) mm, so the cantilever beam hanging on it can adjust the layer height of each layer up and down. The length of the cantilever shelf can be arbitrarily matched, and the shelf factory can be customized according to the storage needs of customers.

Some netizens asked questions and wanted to see press-in shelves.

Today it's coming!

<> press-in shelves are shelves that use trolleys on the shelves to bear the goods and stack the goods forward (backward) in turn when accessing. It is not only a "warehousing problem solver", but also known as "Harvest No. 1".

Look at him, upright column, fixed sea god needle. Thick beams, powerful holes. Move the trolley, stand up to the sky. Convenient storage, first-in, first-out. It is easy to disassemble and can be upgraded. A variety of colors to match your face. Anti-rust surface, not easy to wear.

So what are the disadvantages of it?

The "first-in, last-out" access principle makes it unsuitable for stacking different batches of goods.

The "mobile trolley" access structure makes the depth of its storage location relatively shallow.

Why do people work hard? Isn't it just to make your wallet "burst"!

Gravity shelves.

Evolved from pallet shelves, using roller tracks or bottom wheel pallets, the track is about 3 ° slope, using the weight of the goods, to achieve the first-in-first-out of the goods, one side in and the other side out, suitable for large-volume, first-in-first-out storage operations of similar goods, the space utilization rate is very high, especially suitable for goods with a certain shelf life, not suitable for long-term backlog of goods.

Gravity shelves should not be too high, generally within 6m, the weight of a single pallet goods is generally within 1000kg, otherwise its reliability and operability will be reduced, but at present, domestic companies that provide warehousing and logistics services are not very commonly used this type of shelf system.

Press-in shelves are also evolved from pallet shelves, but the principle of combining the track and the pallet trolley is adopted, the track is about 3 ° slope, the use of the weight of the goods, the realization of the advanced rear out of the pallet goods, the same side in and out of the same side, suitable for the storage of large quantities of small varieties of goods, the space utilization rate is very high, and the access is also more flexible and convenient.

The total depth of the press-in shelf should not be too deep, generally within 5 pallet depths, otherwise the space will be sacrificed greatly due to the mutual embedding of the pallet trolleys; The weight of a single pallet cargo is generally within 1500kg, and the shelf height is generally within 6m.

Press-in shelving system has high requirements for the manufacturing accuracy of the shelf, and the cooperation between the pallet trolley and the guide rail is particularly important. However, in view of the advantages of press-in shelves, even if the cost is higher, some domestic warehousing service companies have a certain application.

According to the summary of Suzhou Creed shelf:Press-in shelves adopt the principle of combining the track and the pallet trolley, the track is a certain slope (about 3 °), the use of the self-weight of the goods, the pallet goods are specified in single-end storage, the goods are advanced in and out of the back, at the same time, the press-in shelves are between the front and rear beams with multi-layer trolleys overlapping, from the outside of the stacked goods are placed in the trolley to push in, and the stored goods will push the original goods inside.

Shuttle rack dense storage system, consisting of racks, shuttles and forklifts. The shelves are designed by the shelf technicians according to the warehouse area, the type of goods stored, the size of the pallet, the shuttle and other factors; The shuttle is an intelligent robot, which is programmed to carry out tasks such as picking, transporting, and placing palletized goods on the shelf track, and can communicate with the host computer or WMS system, combined with RFID, bar code and other identification technologies to achieve automatic identification, access and other functions; Forklifts are purchased according to factors such as shelf height, pallet size, shuttle size, etc., and are used to handle palletized goods, as well as to handle shuttles to different rack tracks.

Press-in shelves are composed of: columns, beams, pallet trolleys, guide rails, forklift shuttle shelves: columns, beams, shuttles, guide rails, forklifts.

Press-in shelves and push-back shelves are derived from beam shelves, which have a large bearing capacity and are suitable for storing heavier items, and are more used in warehouse management. Press-in shelves adopt the principle of combining the track and the pallet trolley, the track is a certain slope (about 3 °), the use of the self-weight of the goods, the pallet goods are specified in the single-end storage, the goods are advanced and the last out, suitable for the storage of large quantities and small varieties of goods, the space utilization rate is very high, and the access is also more flexible and convenient. The gravity shelf is to install an inclined 3-5 ° roller track on the beam, and the palletized goods are imported at the high end, and the self-weight is used to automatically slide to the low end of the pick-up port, which can realize the first-in-first-out storage mode of goods.

Both of them do not need special forklift operation channels, and there are fewer operation channels, which can make full use of warehouse space, increase warehouse storage capacity, and do not require special handling equipment, which can shorten the picking time. Generally speaking, the two are about the same, but the cost of gravity shelves is higher, and in the absence of special needs, there are more push-back shelves.

Do you mean the solution or the structure of the press-in type itself?

I agree with the view of the 2nd floor, which is more comprehensive.

Press-in shelves also evolved from pallet shelves, also known as push-back shelves or push-in shelves. Using the principle of combining the track and the pallet trolley, the track is a certain slope (about 3 °), using the self-weight of the goods, the Guanyu pallet goods are specified in the single-end storage, the goods are advanced and the goods are out, suitable for the storage of large quantities and small varieties of goods, the space utilization rate is very high, and the access is also more flexible and convenient. The total depth of the shelf should not be too deep, generally within 6 pallet depths, otherwise the space will be sacrificed greatly due to the mutual embedding of the pallet trolleys.

The weight of a single pallet cargo is generally within 1500kg, and the shelf height is generally less than 6m. This kind of system has high requirements for the manufacturing accuracy of the shelf, and the cooperation between the pallet trolley and the guide rail is particularly important, such as the manufacturing and installation accuracy is not high, which can easily lead to the poor operation of the shelf system. This kind of shelf has a high cost, and is very suitable for use in cold storage or storage areas where the storage area is limited but needs to be increased urgently, and there are many applications in China.

In China, only a certain scale of shelf manufacturers produce such shelves.

1. Composed of typical structural parts such as pallet trolleys, the pallet trucks have flowable characteristics, and the goods are specified to enter and exit at one end of the shelf, and follow the first-in-last-out order.

2. When storing and transporting goods, the forklift is only located at the lower end of the shelf channel, and there is no need to enter the shelf cargo storage channel. This type of rack has the typical characteristics of high storage density and fast storage and transportation speed.

3. It is usually used in occasions where the storage space is extremely limited, but the storage capacity must be increased or the goods have time requirements, such as low requirements for goods picking.

After the first pallet is picked up during press-in rack pick-up, the next pallet slides to the pick-up point on its own, effectively using a single channel for access and retrieval, especially for storage management in the cargo transit area. Compared with ordinary shelves, press-fit shelves can increase the utilization rate of the ground by about 60%.

The safety and operation efficiency of press-in shelves are higher than those of drive-in shelves, and they can be used only with a reach forklift or counterbalanced forklift, and the requirements for forklift operation are lower than those of drive-in type.

It is suitable for small varieties and large quantities of goods, and the operation mode of first-in-last-out. It is suitable for freezers and other situations that need to greatly improve the utilization of space.
