The working principle of a excavator clam shell hopper is to use the expansion and contraction of the oil cylinder to drive the shell body to open and merge to grab materials, thereby completing the operation. Advantages: Suitable for excavation of foundation pits, deep pit excavation, and unloading and loading of loose materials such as coal and sand in construction sites, especially for excavation or loading operations in restricted spaces. Disadvantage: Weak excavation force, not suitable for some hard soil surfaces, can only grab loose materials.
