How are storage shelves classified?
Answer:
Pressure rack Pumped storage are composed of pallet racking evolution, used rail and the principle of combining the pallet car, track of certain slope (about 3 °), using the dead weight of the goods on pallet advanced after the implementation, the same side in same side out, suitable for large varieties of goods storage, less space utilization high, access more convenient also. The total depth of the shelf is not too deep, usually within 5 pallets depth, otherwise, because the tray car is embedded in the other way, it will make the space sacrifice bigger. The weight of a single consignment is generally within 1500kg, and the shelf height is usually within 6m. Such a system for shelf manufacturing precision demand is higher, the pallet car between the guide rail and cooperation is particularly important, such as manufacturing, and installation precision is not high, easily lead to dysfunctional racking system. Such shelves cost more and have been used in China.
Through shelf The pass-through shelf is also known as the corridor shelf and the entrance shelf. This system shelves arranged densely populated with very high space utilization, is almost twice the pallet rack, but the goods must be few varieties and large quantities, advanced after the goods. First, it is necessary to carry out the unit of the unit, to determine the size of the tray, the weight and the height. This determines the length, depth, and spacing of the unit shelves, and determines the height of the shelves according to the effective height of the lower edge of the roof. By regional wall shelves total depth of the best control within the six tray depth, middle area can both in and out of the shelf area total depth of the best control within the depth of 12 pallets, in order to improve the efficiency and reliability of the forklift truck access (such shelves system, forklift for continuous "exalted skyer" practices, forklift shake easily and hit the shelves, so the stability are crucial to consider fully). Such storage system stability is weak, the shelf is unfavorable and exorbitant, usually should be controlled within 10 m, and in order to strengthen the stability of the entire shelf system, in addition to the specification, selection are larger, solid device must be added. The cargo should not be too big, too heavy, usually weigh in 1500kg, the pallet span should not be greater than 1.5 m. A forklift truck is used as a forklift truck or a balancing ream forklift. It is used in the food industry such as dairy, beverage, etc
Pallet racking Pallet racking, commonly known as beam type shelf, or pallet racking, usually in the form of heavy shelves, in the domestic variety of storage shelves are most common in the system. Must be container unitization work in the first place, the packing and weight features such as group, type, specification and size of the tray, as well as single TuoZai weight and tall (single weight is in commonly 2000 kg), and then determine unit shelves span, depth, layer spacing, according to the warehouse under the roof along the effective height and the biggest fork forklift high decide the height of the shelf. Unit shelves span generally within 4 m, within 1.5 m in depth, low, high warehouse shelves within 12 m in height is in commonly, the elevated height of warehouse shelves generally within 30 m (such basic are automated warehouse, warehouse shelves high total consists of segments within 12 m column). Most of such warehouses, low, high warehouse with forward type battery forklift, balance weight battery forklift, three-way forklift access operations, shelf can also be used when shorter electric forklift, with the elevated warehouse stacker access operations. This kind of shelf system space utilization is high, the access is flexible and convenient, with the computer administration or control, can achieve the requirement of modern logistics system basically.
Put aside plate shelves are usually artificial access goods, packaged structure, uniform layer spacing adjustable, goods are often for parts or not heavy already packaged goods (for artificial access), shelf height is usually below 2.5 m, or artificial reach (e.g., supplemented by truck can be set up at about 3 m). Unit shelves span (i.e. length) shoulds not be too long, the unit shelf depth (the width) shoulds not be too deep, according to the unit of each layer of the load can be divided into light, medium and heavy shelf board type shelf, layer board is mainly for the steel layer board, wooden floor board two kinds.
Gravity shelf Gravity shelves by pallet racking descended, the rolling wheel tracks or bottom tray, orbit in a certain slope (about 3 °), using the weight of the goods, realize the first in first out of the goods, one into the other, is suitable for large quantity, the first in first out of the same goods storage, high space utilization, especially applicable to a certain quality assurance period, should not be the backlog of goods for a long time. Shelves total depth (that is, the guide rail length) should not be too large, or not to use up and down "blind Angle" will be larger, influence space utilization, and the slope is too long, will slide in the controllable is poorer, falling impact is bigger, easy cause decline, block, tray of the tilting of the goods. To make the slide smoothly, such as a long ramp, should be set up in the middle damping device, in order to make pallet fell to the bottom when not tilting because of the impact force is too large, should be a minimum of the ramp buffer device and pickup separation device, therefore the design, manufacture, installation is difficult, the cost is higher. This kind of shelf should not be too high, generally within 6m, the weight of the individual goods is within 1,000 kg, otherwise the reliability and operational will be reduced. Such shelf systems are currently not widely used in China
