Walking and floating navigation principle: This model of wetland excavator uses specially designed trapezoidal cavity-type track pads, and the sealed cavity structure generates buoyancy during movement, allowing the whole machine to walk stably on soft ground and shallow water areas. The large contact area of the track pad design effectively reduces the ground pressure ratio, preventing the equipment from sinking into soft ground.

Excavation operation: It adopts a backhoe working device, which completes the excavation operation through the coordinated action of three groups of hydraulic cylinders - the boom, dipper arm, and bucket. The operator sends commands through the pilot control handle, and the hydraulic system transmits power to the hydraulic cylinders of each working device, realizing the lifting and lowering of the boom, extension and retraction of the dipper arm, and digging action of the bucket.
