The rock expander is an engineering tool primarily used for drilling and expanding operations in rock or hard strata. This equipment is made of high-strength materials, featuring excellent wear resistance and compressive strength. Its main function is to create holes of a certain diameter in the rock using powerful hydraulic or mechanical forces, facilitating subsequent construction activities such as pipeline laying and cable crossing.
