Warehouse Rolling Storage Gravity Carton Flow Metal Racking

Gravity racks belong to pallet storage racks in storage racks. Gravity shelves use a first-in-first-out storage method, and the depth and number of layers of the shelves can be determined as needed. Gravity racks are suitable for the storage of small varieties and large quantities of similar goods.

Gravity racks structure

Gravity racks evolved from pallet racks, using roller track or bottom wheel pallets.

Working Principle

Gravity racks, also known as roller racks, belong to pallet storage racks in warehouses. Gravity racking is one of the derivatives of warehouse pallet racking. The racking structure is similar to pallet racking, except that roller rails are installed on the beams, and the rails are inclined at 3-5°. Pallet goods are transported by forklift to the inlet of the rack, and the pallet automatically slides from the inlet to the pickup port at the other end by using its own weight. Gravity shelves are a first-in, first-out storage method.

Features of Warehouse Gravity Carton Flow Sliding Racks

• 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 the cargo, a damper is arranged on the slideway to control the sliding speed of the cargo to be kept within a safe range. A separator is provided at the delivery end of the slideway, and the handling machine can smoothly take out the goods at the position of the first board.
• The goods follow the first-in, first-out order. The shelf has high storage density and flexible matching function.
• It is suitable for storage operations with pallets as the carrier, and the goods are stacked neatly, providing a better solution for the storage of large and heavy objects. The utilization rate of storage space is over 75%, and only one entry and exit channel is required;
• Gravity racks are very environmentally friendly, all of which are in the form of no power, no energy consumption, low noise, safe and reliable, and can operate at full load.

There is no working channel between groups of shelves, thereby increasing the space utilization rate by 60% and improving the volume ratio of storage; pallet operation follows the principle of first-in, first-out; automatic storage rotation; separation of storage and picking actions Greatly increases output, reduces the number of transport routes and forklifts due to self-gravity sliding the goods and no access to operate

Precautions

The total depth of the rack (that is, the length of the guide rail) should not be too large, otherwise the unusable upper and lower “dead corners” will be large, which will affect the space utilization, and if the ramp is too long, the controllability of sliding will be poor, the momentum of sliding will be large, and it is easy to Causes poor sliding, blocking, and overturning of palletized goods. In order to make the sliding smooth, if the ramp is long, a damping device should be installed in the middle. Therefore, it is difficult to design, manufacture and install, and the cost is high. Such shelves should not be too high, generally within 6 meters, and the weight of a single pallet is generally within 1000KG, otherwise its reliability and operability will be reduced.
