The working principle of a mini excavator shell bucket is to use the expansion and contraction of the oil cylinder to drive the shell body to open and merge to grab materials, thus completing the operation.
Usage of mini excavator shell bucket
Suitable for excavation of foundation pits, deep pits, and unloading and loading of loose materials such as coal and sand in construction bases, especially for excavation or loading operations in restricted spaces.
Characteristics of mini excavator shell bucket
1. Optional 360 ° rotation.
2. The hydraulic closing force is very strong. During the excavation process, it can maintain a constant closed excavation force, making it have better excavation characteristics. It can be installed on the forearm end with a rigid connection to ensure reliable operation, and the oil circuit of the bucket hydraulic cylinder can be used to supply oil to the grab.
3. Equipped with hydraulic cylinder protection function. During the entire clamping process, a constant clamping force can be maintained to achieve better clamping characteristics. It has a wide pivot distance, and the gripper has a large clamping range and volume.
4. The disadvantage is that the excavation force is weak, which is not suitable for some hard land surfaces and can only grab loose materials.
