K450A fully automatic drilling rig (Dilong’s latest patent) is a new type of automatic loading and unloading drilling rig. It can carry a sufficient amount of drill rods and realize automatic loading and unloading, which can greatly reduce the configuration of crew members.
Different from the “side-mounted” loading and unloading drill rod machine used by traditional European and American fully automatic drilling rigs, K450A uses Dilong’s original “inclined top-mounted” automatic loading and unloading drill rod mechanism. Drill rods can be loaded and taken out from the side, which is very convenient.
