Double-row single extension telescopic fork

       The bidirectional telescopic transfer fork for stackers, also known as the stacker fork or transfer fork, is referred to by various names such as the bidirectional telescopic fork for stackers, bidirectional telescopic pallet fork, or bidirectional transfer fork. It is a material transfer mechanism with flexible bidirectional automatic telescoping and precise positioning functions. Often used in conjunction with lifting mechanisms, it can easily transfer materials from one side to another. It can interface with production management systems to enable intelligent management and operation, and is widely used in automated storage and retrieval systems (AS/RS), smart warehouse systems, or automated production lines!
Structurally, it comes in various types. For example, mechanical structures include single-reach (or single-depth) structures and double-reach (or double-depth) structures. In terms of transmission mechanisms, there are gear-rack-chain combination transmission structures, pure gear transmission structures, and synchronous belt transmission structures. In terms of operational structures, there are single-finger (also called single-row or single-arm) operational structures and double-finger (also called double-row or double-arm) operational structures. Different transfer requirements call for forks with different structures!
       Additionally, due to varying operating environments, the materials used for the forks differ. For example, high-temperature environments like furnace operations, low-temperature environments like cold storage operations, and fully enclosed dust-free environments (including Class 10,000, Class 1,000, and Class 100 clean environments) require different materials. These may include high-strength carbon steel, lightweight aluminum alloy, or waterproof, rust-resistant, corrosion-resistant, and temperature-resistant stainless steel materials!
The so-called single-reach (or single-depth) structure refers to a fork whose travel can extend into or reach a single storage location. Its transfer distance is relatively short, only slightly longer than the fork body itself. It consists of three fork sections: one fixed fork body and two movable fork bodies. In contrast, the double-reach (or double-depth) structure refers to a fork whose travel can extend into or reach two storage locations, either front and back or inner and outer layers. Its travel is larger, with a transfer distance more than twice the length of the fork body. It consists of four fork sections: one fixed fork body and three movable fork bodies!
The gear-rack-chain combination transmission structure is a traditional design, relatively simple and easy to maintain. However, after prolonged use, the chain may stretch (or elongate), leading to operational inaccuracies with deviations of around ±3mm. The pure gear transmission structure, on the other hand, offers higher operational accuracy, with repeat positioning accuracy of about ±0.5mm. The synchronous belt transmission structure is a lightweight fork design but is not widely used due to its limited load capacity!
The single-finger (or single-row, single-arm) operational structure refers to a single set of fork arms operating independently to complete transfer tasks, mainly used for transferring small-volume, lightweight materials. The double-finger (or double-row, double-arm) operational structure involves two sets of fork arms synchronized via couplings, primarily used for transferring large-volume, heavy materials. Both can adopt either single-reach or double-reach structures!

       Simply put, the double-row single-reach bidirectional telescopic transfer fork for stackers refers to a transfer mechanism composed of two sets of three-section fork arms with bidirectional telescoping functionality. It features small full-load deflection, high load capacity, and stable operation. It can be made from various types of fork body materials and employ different transmission methods to meet the needs of diverse operating environments!
