Reach Stacker Mechanical Training Platform

　　Product name

　　Reach stacker mechanical training platform

　　Model (Type)

　　HKZMDJX type

　　Feature

　　Hydraulic reach stacker is a kind of machinery for container loading and unloading, which is widely used in port, iron road and road transportation operations. At present, almost all small and medium reach stackers are hydraulically driven. The hydraulic reach stacker has the advantages of small size, light weight, flexible and convenient operation, large lifting force, easy to achieve overload protection and indoor operation. In recent years, the application of high-tech microelectronics technology in hydraulic technology has made the comprehensive technical level of construction machinery, construction machinery and transportation machinery higher and higher, and improved the reliability, operational safety, comfort and service life of these machinery. more adaptable. 1. The test bench is made of cold-rolled steel plate (and has been sprayed and treated with anti-corrosion), with a desktop structure and integrated control and operation.

　　2. The electrical operation control is under-mounted, and the hydraulic station is placed in the main cabinet of the hydraulic table. The overall structure is compact and coordinated, the layout is beautiful and generous, and the practicability is strong, which can be used for 4-6 people to experiment.

　　3. The all-metal structure of the reach stacker machine is scaled down according to the actual object. During the experiment, the hydraulic system is activated to operate the machine according to the experimental requirements.

　　4. The reach stacker is made according to the structure and scale of the real object, which can truly reflect the actual working conditions of the machine, so that students can deeply understand the structure and working principle of each part of the mechanism in the experiment.

　　5. The experimental control adopts manual control and automatic control.

　　6. The experimental part adopts pressure-resistant rubber hose, and the pressure can reach 25Mpa.

　　7. With three-phase leakage protection, the output voltage is 380V/220V, and the power supply is cut off when the leakage current to the ground exceeds 30mA; the electrical control adopts DC 24V power supply, and has overvoltage protection to prevent misoperation from damaging the equipment.

　　Training contents

　　1. Reach stacker mechanical demonstration control experiment

　　1) Snatch operation, the snatch beam is positioned according to the length of the container;

　　1) The lifting operation, the main boom and the telescopic boom are combined for working experiments;

　　2) Rotation operation, lifting the snatch beam while the platform rotates; (with motor rotating platform)

　　3) Obstacle operation, when the main arm and the telescopic arm work together, the servo cylinder at the top of the telescopic arm or the four obstacle detection cylinders distributed on the four corners of the snatch beam encounters obstacles, and gives the main system a stop or drop command (optional);

　　4) Return, the platform rotates, the main arm and the telescopic arm cooperate to return to the initial position.

　　2. Programmable Logic Controller (PLC) electrical control experiment: machine-electric-hydraulic integrated control experiment.

　　1) PLC instruction programming, ladder diagram programming learning;

　　2) Learning and use of PLC programming software;

　　3) Communication and online debugging between PLC and computer;

　　4) Application of PLC in hydraulic transmission control and optimization of control scheme.
