The semi-automatic garbage crane mainly means that the driver selects the feeding point, manually grabs the garbage, and then presses the button of the feeding port corresponding to the lack of material incinerator. The crane grab will automatically move to the selected feeding port. Bucket feeding. After the feeding is completed, the driver determines the position of the next picking point. Can realize manual control, semi-automatic control operation.
For garbage grab cranes, it is divided into three types according to the level of the crane's operation control system: manual control grab cranes, semi-automatic grab cranes and fully automatic control grab cranes.And the crane work duty is A7/A8.
The garbage grab crane is a kind of grab bridge crane. As the core equipment of the garbage supply system of various garbage incineration power plants in modern cities, it is located above the garbage storage pit and mainly undertakes the feeding, handling, mixing, Picking and weighing operations.
The grab is usually a hydraulic six-petal grab, and the crane operates in a closed garbage room around.
Considering the serious pollution in the garbage room, the fixed driver's cab is generally used and is arranged opposite to the feeding port. The driver can observe the sealed glass window to control the operation of the crane.

Grab Crane Configuration:
The control system of garbage grab crane is composed of control handle, PLC, manual console, upper computer, frequency converter, operating position point, feed inlet status, video monitoring module. The main body of the crane is driven by the cart, motor, cart, trolley, It is composed of grab, bridge, reel, hoist motor, trolley driving motor, and platform railing. Each motor on the crane uses a frequency converter and a special motor, and each motor is equipped with a coaxial high-precision photoelectric rotary encoder. The pulse signal from the encoder, the encoder and the signal of the ultrasonic position sensor on the trolley are processed by the controller, and the position of each mechanism of the crane is output to the upper computer; it is automatically controlled by the PLC upper computer, the set control handle and manual control It has the advantages of simple operation and automatic control.
Grab Crane Features:
1.High precision and accurate weighing measurement. Static accuracy is 0.3% -0.5% F.S, comprehensive accuracy is 0.5% -2% F.S.
2.Based on RFID technology, it automatically locates and automatically obtains weighing results.
3.Weighing is unattended. Without manual intervention, weighing records and data reports are automatically generated to prevent cheating.
4.The data statistical report is true and accurate, and the content of the software monitoring screen is clear and complete.
5.In summary, the garbage crane intelligent weighing management system ensures accurate, reliable and stable, while effectively reducing cost.
