There are mainly the following classifications: chain conveyor, roller conveyor, transfer conveyor. 1. Chain type conveyor The chain conveyor is driven by a geared motor, the motor is installed on a preset pedestal, the chain rolls on section steel, constitutes a whole with the structure of the conveyor and is positioned under the chain; the motor reducer rotates at a pre-designed speed by sprocket and chain, thereby driving the tray cargos on the chain to move, so as to achieve the purpose of conveying the tray cargos.2. Roller type conveyorThe powered roller conveyor is composed of the powered roller module, the aluminum veneer, the card-frame, the pull rod, the bearing seat, the driving device and the chain. The non-powered roller is composed of non-powered roller module, the aluminum veneer, the card-frame, the pull rod and the bearing seat. The powered roller rotates to conveys cargos because the driving device drives the drag-chain, and the chain drives the sprocket on each powered roller. The non-powered roller conveys things freely by pushing and pulling workpieces by people or squeezing between workpieces.3. Transfer conveyorThe lifting transfer conveyor is generally used to change the conveying direction of the cargos, and move the cargos into or out of the main conveying line from the minor line. It has the characteristics of large load, simple structure, stability and reliability. The equipment adopts PLC programmable control, so that cargos can easily enter and exit the main and minor conveying lines without collision, extrusion and other phenomena. The lifting transfer conveyor we developed adopts four fulcrums for balanced lifting. Even if cargos are not placed correctly and the side or corner of the equipment is stressed, the conveyor can still be lifted smoothly without blocking or jamming. And the main advantage is the right-angle turn: the conveyor can realize right-angle turns under the condition of limited space which could save space.

Recently, our company welcomed a Romanian client for an on-site visit. This exchange was not our first connection. Previously, our company had completed initial communication with the client and provided a first draft of the four-way intensive warehouse solution based on their requirements, laying a solid foundation for this in-depth discussion. To ensure an efficient and smooth visit for clients, the company"s reception team made preparations in advance. They not only repeatedly confirmed basic information such as the arrival time and hotel location with the client, but also formed a dedicated reception team of "technical experts + professional translators" based on the core requirements of the four-way intensive warehouse solution, with clear division of labor for providing comprehensive support in explanation, answering questions, and communication. On the day of the visit, staff arrived at the client"s hotel on time to pick him up, starting the exchange with professional service. During the client"s visit to the demo system, Manager Yan, the technical staff, provided a detailed explanation of the system"s operation and the differences between the demo system and the actual implementation system. Manager Yan also addressed the client"s questions from a professional perspective, answering their inquiries and highlighting the unique advantages of our four-way intensive warehouse. The staff also showed the client the assembly area of the four-way shuttle. The client could closely observe the internal circuitry and mechanical structure of the shuttle, and also appreciate the high quality, stability, and reliability of our product components. In addition, the staff showed the client the racking samples, focusing on the different thicknesses of the racking. Following the site visit, both parties moved to the conference room to discuss the project plan . A key requirement from the client was that the new warehouse be connected to the existing one. Currently, the client has an existing, operational warehouse next to the new one. In previous communications, the technical staff were unclear about how the existing warehouse operates. During this discussion, the client explained their existing warehouse"s operating model to the technical staff, where pallets and workbins are stored separately, and they hoped to move all pallets to the new warehouse in the future. After understanding the client"s requirements, the technical staff revised the plan while communicating with the client. Another unique aspect of this project is its diverse product range and high efficiency in inventory management. The client was hesitating about the number of elevators. Initially, our company proposed a two-elevator solution. However, during this discussion, considering both efficiency and system stability, we ultimately recommended a four-elevator solution . This face-to-face communication not only brought both parties closer but also allowed our company to accurately identify the client"s potential needs. In future, Nanjing 4D Intelligent Storage Equipment Co., Ltd. will continue to focus on technological research and development, steadily advance the implementation of each project, further strengthen its competitiveness in the overseas intelligent warehouse market, and provide more international clients with customized, cost-effective warehousing solutions!
