DZ Type Monorail Trolley Overhead Conveyor (Electric Monorail Self-Propelled Trolley)
Darui Electric recommends
The electric monorail self-propelled trolley is a new type of fully automatic material storage and transportation system, similar in appearance to electric hoists and power-and-free overhead conveyors, and functionally between the two.

1. Functional features:
(1) Distributed drive: The power is changed from centralized drive to separate drive for each conveying unit (trolley);
(2) Action control: The control system can control each material conveying unit in real time. The conveying trolley can perform various actions such as lifting, traveling, and swinging at the workstation as needed;
(3) Accumulation method: The running trolley is controlled by the electrical control system to stop at the working position and automatically accumulate and stop when encountering obstacles during operation.
(4) Three-dimensional network: The material route is composed of tracks, transfer switches, turntables, and lifts, forming a three-dimensional network for material transportation;
(5) Modular assembly: The track, switches, and other functional systems of the self-propelled trolley are mature components, and the control methods are also mature, allowing arbitrary combination, with short manufacturing, construction, and delivery cycles;
2. Scope of application:
(1) Multiple control modes: Centralized control, distributed control, or centralized-distributed control can be adopted, and the running trolley works reliably according to preset programs. Set the working station address, fixed-point work, fixed addressing, suitable for painting production lines and assembly lines;
(2) Random logistics supply system: The working station makes real-time material transportation requests, and the system randomly writes the address code of the requesting station to the running trolley, which then goes directly to the material-requesting station and returns with the supply. The running trolley has the functions of random address recognition and random address writing. The station's material request can be manual or automatically initiated by the central control room monitoring the material status of each station, and it can be networked with the management computer system. It is suitable for ***, internal combustion engine components, and product warehousing and conveying lines.
(3) Sorting system: The running trolley carries different address codes according to the different goods it carries. Ground reading stations are set up to determine the direction and destination of the trolley. Suitable for postal sorting lines, internal combustion engine testing lines, quality inspection lines, and textile system conveying lines.
1. Main functional components:
(1) Traveling track: For conveying systems with a load capacity below 2t, aluminum alloy rails are often used as the traveling track, making the laying of the conveying line more ideal and ***. Our company uses high-strength aluminum alloy, which is surface oxidized and has good strength and wear resistance. The customized double-T structure ensures reliable connection with steel auxiliary beams and sliding contact power rails. Our company has introduced technology from France's Vallet company to design a dedicated sliding contact line for the electric self-propelled trolley system, which is reliable and easy to install. For conveying systems above 2t, H-beam steel is recommended as the traveling track.
(2)Sliding contact power rail The sliding contact type plays an important role in supplying three-phase four-wire power and transmitting control signals in the electric self-propelled trolley system. The quality of the product directly affects the reliability of the system. Our subsidiary, Wuxi Huadao Electric Appliance Factory, is a manufacturer specializing in sliding contact power transmission devices, and the national standard for sliding contact mobile power supply devices was drafted by our company. The self-propelled trolley adopts a double carbon brush structure for more reliable signal transmission;
(3) Transfer switches, turntables, and lifts: To form a three-dimensional conveying network, transfer switches, turntables, lifts, and other system components are installed at appropriate positions on the conveying line, allowing the traveling trolley to transfer from one track to another, meeting the functions of material diversion, merging, and transfer;
(4) Running trolley: The running trolley is divided into two categories: ordinary type and intelligent type. According to traveling speed, it can be divided into fixed speed and variable frequency speed regulation types. The running trolley is composed of two to multiple car groups depending on the material. Each running trolley has the function of automatically stopping when encountering obstacles and automatically walking when obstacles disappear. The running trolley can be controlled by its own control pendant or ground button station;
(5) Spreader: The spreader connecting materials has two modes: manual and automatic, and can be selected for users according to different process requirements. Of course, users can design it themselves and connect it to the hoist hook of the running trolley.
(6) Electrical control system: The electrical control system consists of programmable logic controllers, encoding devices, address recognition devices, position sensors, and other actuators. With different control programs, it processes various action requirements of the functional components of the conveying system in real time and completes the process actions of the entire conveying system. Physically, it is generally divided into the main control cabinet, button stations at each station, trolley electric control cabinets, and alarm display devices; for large and complex systems, there may be a central control room, programmable logic controller networks, and other functional components.
With the rapid development of e-commerce, the continuous increase in transportation orders has brought new challenges to modern logistics systems. The integration of materials and goods flow has driven the automated logistics system into a high-demand level.
