Rotary And Non – Rotary Excavator Grid Grapple For Stone Loading And Safe
Description:
1. Grid Grapple rely on a combination of left and right grabhook to open and close to grab and unloading bulk material;
2. Grid grapple is a hydraulic grapple, hydraulic grab equipped with opening and closing structure itself, generally driven by hydraulic cylinders, hydraulic grapple uses widely in hydraulic special equipment, such as hydraulic excavators, hydraulic lifting tower.
3. Hydraulic grapple is hydraulic structures’ products, is composed of hydraulic cylinders, bucket (jaw), connected column, bucket ear plate, bucket earmuffs, bucket teeth, adapters and other parts, so welding is the most critical hydraulic grab production process, welding quality directly affects the structural strength and hydraulic grab life. Another hydraulic cylinder is the most critical drive components.
4. Grid grapple can be divided into rotating and non-rotating type, non-rotating type using the excavator bucket cylinder oil-way, do not need to add another hydraulic valve block and piping; rotating type need to add a hydraulic valve block and piping to control.
Parameter:
| Model | Adaptor excavator tonnage(ton) | Weight(kg) | Cylinder flux(L/min) | Cylinder pressure(bar) | Rotary (L/min) | Rotary pressure(bar) |
| YT80 | 6-12 | 680 | 60-80 | 320 | 25 | 160 |
| YT150 | 13-18 | 1100 | 80-100 | 320 | 25 | 160 |
| YT200 | 20-26 | 1400 | 100-120 | 320 | 25 | 160 |
| YT300 | 25-30 | 1950 | 120-140 | 320 | 25 | 160 |
| YT350 | 30-36 | 2200 | 120-160 | 320 | 25 | 160 |
The characteristics and advantages:
1. Design for grid grab working
2. Greatly improve the efficiency of loading and unloading
3. Driven by hydraulic double cylinder
4. Great help to save the human resources
5. Ensure use safety
6. Convenient and quick for operation
7. can rotary back and forth of 360°
Grid Grab can rotary back and forth of 360°by driver, can guarantee the accurate positioning while working. Driven by double
cylinders, ensure it has enough power to grab the stone, short time for opening and closing , improve the working efficiency.
Application :
1. Building foundation pit excavation, pit mining and mud, sand, coal, gravel loading.
2. Especially for the side of the ditch or restricted space digging and loading.
3. Applies to ships, trains, cars handling.
