drill rig technical requirements and higher maintenance costs, currently in China only as a complement of other drilling equipment. With advances in technology and development, hydraulic rock drill gradually replaced pneumatic rock drilling rigs equipment Chapter of the use of technology for hydraulic rock drill 1) hydraulic  rock drill before the start of check accumulator charging pressure is normal; Check the rinse water pressure and lubrication air pressure is correct; Check the crawler drilling rig for sale lubricator years for enough oil, fuel supply is appropriate; checking the direction of rotation of the drill rigs pump motor.
