Hydraulic grab is a product of hydraulic structure, which is composed of hydraulic cylinder, bucket (jaw plate), connecting column, bucket ear plate, bucket ear sleeve, bucket teeth, tooth seat and other parts, so welding is the most critical part of hydraulic grab The manufacturing process and welding quality directly affect the structural strength and service life of the hydraulic grab. In addition, the hydraulic cylinder is also the most critical drive component.
