YGSZ850 "dual power" Hydraulic Crawler grab feeder Henan Yellow Sea Technology R & D department has developed "hybrid" drive function of terminal handling equipment, the product is expected to grasp mobile devices to meet a variety of gravel, coal , Grain, mineral soil, stone, steel, wood and other bulk cargo handling operations have the following advantages:

1. It is driven by mechanical and electric hybrid power, which can be driven by internal combustion engine or electric motor, which is flexible and flexible. Driven by electric motors, low maintenance costs, no pollution, and low failure rate. Electric motor operation is one third of the operation cost of internal combustion engine;

2. According to the requirements of the operation, the plum blossom gripper, electromagnetic chuck and other accessories can be added;

3. The equipment adopts full hydraulic drive, pilot handle, stepless speed regulation operation function, stable operation.

4. The hydraulic series adopts: ①Dual power drive, double pump and double circuit total power adjustment, negative flow control open system; ②Dual power drive, double pump and double circuit power control, with pilot pressure override control, positive flow control open type system.

5. The equipment is equipped with a hydraulic oil strong wind heat dissipation device, which can ensure that the temperature rise of the hydraulic oil does not exceed 80°C during continuous operation of the equipment, effectively prolonging the service life of the hydraulic seals;

6. In addition to the two boom cylinders, a compressed nitrogen cylinder is added to help the boom lift, increase lifting force and improve work efficiency. Recover the use of compression to reduce kinetic energy and save power output.

7. The equipment has safety limit devices such as luffing and rotation, and the operation is safe and reliable;

8. Optional installation of weighing instrument;

9. The gripper rotating head is optional, so that the gripper has a 360° rotation function, especially for directional raw materials, with a better gripping effect.

10. The whole car is equipped with an automatic lubrication system to solve the problem of easy damage to the shaft sleeve when the grease is forgotten.

11. The grabber adopts a gantry with elevated outriggers, and vehicles can enter and exit from below.

12. The boom is designed with a semi-circular arc using the principle of mechanics to enhance the supporting force.

13. The use of double-rotating motors makes it run faster and easier.

14. Cummins brand engine guarantees power output.

15. The hydraulic pipeline of the whole vehicle adopts American Eaton to eliminate the phenomenon of oil leakage such as explosion, seepage, leakage and cracking.

16. The air conditioner is added to ensure fast and strong cooling and heating, and more comfortable operation.
