Its stated business scope covers hydraulic equipment, mining machinery, mechanical equipment, rail-transit spare parts, petroleum machinery, CNC equipment and accessories, together with import and export activities.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, and lists installation, training, repair, maintenance and debugging among its overseas services.
