gravity flow racking system

Category

The goods are deposited from the high end, slid to the low end and taken out from the low end. During the sliding of the goods, a damper is set on the chute to control the sliding speed of the goods to keep within the safety range. There is a separator set at the shipping end of the slide, and the handling machinery can take out the goods at the first pallet position smoothly. Gravity racking is very environmentally friendly, all in the form of no power, no energy consumption, low noise, safe and reliable, and can operate at full capacity. The goods follow the principle of first-in-first-out. The racks have the characteristics of high storage density and fast storage efficiency.

What is gravity flow racking?

Gravity racking systems belong to the pallet type storage racking in storage racking. Gravity racking is one of the derivatives of beam racking. The structure of the racking is similar to that of beam racking, except that a roller-type track is placed on the beam and the track is inclined at 3-5°. The pallets are carried by forklift to the inlet of the racking, and the pallets are automatically slid from the inlet to the pick-up area at the other end using their own weight. Gravity pallet racking is suitable for storage operations with pallets as the carrier, and the goods are neatly stacked, providing a better solution for the storage of large and heavy goods, with a storage space utilization rate of more than 75%, and only one inlet and outlet is required. Such racks should not be too high, generally within 6 meters, the weight of a single pallet of goods generally within 1000KG, otherwise its reliability and operability will be reduced. Gravity racking system belongs to the FIFO storage method.

Installation of gravity flow racking

The design and installation of gravity pallet racking is more complicated. The total depth of the rack should not be too long, the depth is too long then will lead to the unavailable up and down free space will be larger, and the controllability of the slide will be poor, easy to cause the slide is not smooth, the pallet of goods overturned, etc.. In order to make the pallet goods slide to the bottom when the impact force is too large and not overturned, should be set up at the lowest part of the ramp buffer device and pick-up separation device.

The Main Production Process Of Gravity Flow Racking

bg10
1
Punching Process

Punches run the length of the hanging plate at standard intervals where the cross beams are connected, most of them are 50mm or 75mm pitch.

2
Rolling Process

Steel coil through the rolling equipment to form the upright and beam, beam usually have P beam and interlock beam, upright usually have diamond hole and teardrop hole.

3
Welding Process

Through welding, the hanging plate and beam; upright and footplate are closely connected together, which effectively strengthens the stability of the rack structure.

4
Spraying And Baking Process

Polish the product after welding, then use electrostatic powder spraying technology on the surface, and finally use the high-temperature baking process to ensure a smooth surface.

5
Packaging Process

Finally came to the last step. After the production of the product is completed, we usually package the exported goods to avoid long-distance transportation damage and seawater erosion during shipping.

What you want to know about gravity flow rack

There are generally no fixed dimensions for gravity flow racking system. Because gravity racking system is almost 100% custom-made, the size of the racking is determined by the customer’s warehouse or goods. In order to meet the maximum storage needs of different customers, there are basically no duplicate racks, which also determines the size difference.

Gravity flow racking system is a more complex type of racking with a complex structure, with dampers, rollers, etc. The price of the entire system, including the racking, dampers, rollers, etc., is naturally relatively high, and may be as much as $80 for one space.

Gravity flow pallet rack is one of the derivatives of beam racking. The structure of the racking is similar to beam racking, except that a roller type track is placed on the beam and the track is inclined at 3-5°. The pallets are carried by forklift to the inlet of the rack, and the pallets are automatically slid from the inlet to the pick-up port at the other end using their own weight. Gravity flow racking system is a FIFO storage method.

1. The goods are deposited from the high end, slid to the low end and taken out from the low end. During the sliding process of goods, there is a damper set on the chute to control the sliding speed of goods to keep within the safety range. There is a separator set at the shipping end of the chute, and the handling machinery can smoothly take out the goods at the first board position.

2. The goods follow the order of first-in-first-out. The rack has high storage density and has flexible fit function.

3. It is suitable for storage operation with pallet as carrier, and the goods are stacked neatly, which provides a better solution for the storage of large and heavy goods, and the utilization rate of storage space is more than 75%, and only one inlet and outlet channel is needed;

4. Gravity flow racks for pallets are very environmentally friendly, all in the form of no power, no energy consumption, low noise, safe and reliable, and can operate at full capacity.

There is no operation channel between groups and groups of racks, thus increasing the space utilization rate by 60% and improving the volume rate of storage; pallet operation follows the principle of first-in-first-out; automatic storage slewing; the separation of two actions of storage and picking greatly improves the output, and since it is self-gravity that makes the goods slide and there is no operation channel, it reduces the number of transportation routes and forklifts.

Gravity rack evolves from selective pallet racking, using roller tracks or bottom wheeled pallets, the tracks are inclined and using self-weight, the pallets automatically glide from the inlet to the pick-up port at the other end.

The total depth of the rack (i.e., the length of the rail) should not be too large, otherwise the unavailable up and down “free space” will be larger, affecting the use of space, and the ramp is too long, the controllability of the slide will be poor, the impulse of the slide is larger, easy to cause the slide is not smooth, blocked, the pallet of goods overturned. In order to make the slide smooth, such as a long ramp, should be added in the middle of the damping device, in order to make the pallet goods slide to the bottom when the impact is not too large and overturned, should be set up at the lowest part of the ramp buffer device and pick-up separation device, so the design, manufacturing, installation is more difficult, the cost is higher. These racks should not be too high, generally within 6 meters, the weight of a single pallet of goods generally within 1000KG, otherwise its reliability and operability will be reduced.

There is no operation channel between groups of gravity racks, thus increasing the space utilization rate by 60% and improving the volume rate of storage. The pallet operation follows the principle of first-in-first-out, automatic storage slewing, and the separation of the two actions of storage and picking greatly improves the output, and since it is self-gravity that makes the goods slide, and there is no operation channel, the number of transportation routes and forklifts is reduced.

Gravity flow racking system can make full use of the warehouse area, about 30% higher than the general utilization rate of fixed racks warehouse area, especially suitable for the storage of goods with fast turnover and the requirement of first-in-first-out, such as breweries, food factories and the application of various production lines. In some advanced countries, such as the United States, Japan and Western Europe, has been widely used in some small warehouses and some storage should not be long-term backlog of goods in three-dimensional warehouses and production lines, design and manufacturing technology has also been quite mature. With the continuous development and maturity of gravity flow pallet rack technology in China, the demand for gravity flow racks warehouses is also increasing, except that due to the relatively high cost of gravity rack, the application rate of small business warehouses in China is not very high.

The slope of the chute is too small, the pallet will not slide or slide smoothly; the slope is too large, the pallet slides too fast and will cause impact or tipping. Therefore, the size of the slope should be reasonably selected. In addition, the size of the slope also depends on the material of the pallet bottom, for wooden pallets, generally desirable 3.5% to 3.0%; for plastic pallets, desirable 2.5% to 2.0%; for steel pallets desirable 2.0% to 1.5%. In the actual warehouse design, the best choice of slope should be determined after detailed calculation and experiment.

Both types of racks rely on the weight of the goods themselves to let the goods slide from one end of the rack to the other, the difference is that gravity racks are usually used to store goods loaded with pallets, while carton flow racks are often used for cartons and other small packages of wrapped goods.
