Chain guard

The excavator arm moves back and forth, requiring frequent braking and lifting. Most of the potential energy is consumed on the multi way valve port, which not only wastes energy, but also converts a large amount of potential energy into thermal energy, increasing fuel consumption, and easily causing hydraulic system heating, reducing the lifespan of components.
