★ Drive-in racks, also known as drive through racks or corridor racks. It is composed of frames, brackets, pallet rails, top beams, back beams, top bracings, back bracings, etc., suited to large stocks of few products types, it has higher space utilization by accumulation storage with excellent use of available warehouse space, product is stored several pallets deep, handling equipment will enter the rack structure to slot or extract pallets. It is widely used in cold chain logistics, beverages, food, dairy products and other industries.
★ It can realize FIFO and FILO loads methods. As the forklift are always at a high lifting mode with cargo weight, it is easy to shake and hit racks especially on the uneven ground, so a highly skilled driver is required to ensure the stability and safety of rack structure. However, turnover efficiency of goods is affected to be lower.
★ Structural design is the most critical factor of drive-in racks quality, the raw material, production technology and equipment, tooling and powder coating, etc., will directly determine the rack quality also. The drive-in rack is a statically indeterminate spaced steel structure, it is quite cumbersome to calculate its strength, stiffness and stability by traditional classical mechanics or dynamics methods. Simplified calculation models can be used and combined with domestic and foreign standard specifications and test data Analyze and optimize the design. At present, finite element structural strength analysis and stability analysis are mostly used for auxiliary design and full-scale load test verification.
★ Compared with drive-in racks, shuttle racking system has advantages of high land utilization, high storage efficiency (saves time on forklifts driving in/out racks), and which can be quick improved by adding more shuttles; storing more varieties of goods placed on different layers, easy and efficient storing even at high layers.
