LANDSONG JH7 core drilling rig | All the frustration you experienced on the construction site is now fully remembered by the upgraded JH7 model!
On the plateau, the engine was emitting black smoke and lacked power; in the clayey soil layer, drilling was difficult as the drill bit got stuck and no progress was made for a long time; removing the drill pipe required using a sledgehammer and pipe wrench, leaving one drenched in sweat; working continuously in summer, the machine became so hot that it made one feel anxious...

For core drilling machines, who hasn't encountered these annoying problems - On the plateau, the engine emits black smoke and lacks power; in clayey soil layers, drilling gets stuck and the hole doesn't advance for a long time; removing the drill pipe requires a sledgehammer and pipe wrench, leaving you sweating profusely; working continuously in summer, the machine gets so hot that it makes you feel anxious... These problems have been repeatedly heard during our investigations at various construction sites. And to solve these difficulties, it is not necessarily necessary to purchase high-priced custom-made drilling equipment. The upgraded version of the "LANDSONG JH7" fully hydraulic core drilling machine offers you the best solution at the lowest cost!
Problem 1: Feeling tired on the plateau, emitting black smoke → Plateau modeWhen the altitude is high, the engine seems to be "having difficulty breathing", emitting smoke, getting stuck, and losing power. The construction efficiency drops sharply.The upgraded LANDSONG JH7 core drilling rig adds a plateau mode. Through high-pressure filtration and a dedicated valve group to optimize combustion, the engine can still burn fully and output power steadily at high altitudes - no smoke, no stuck, and construction on the plateau no longer requires anxiety.
Problem 2: Stuck drill due to clayey formation → External flushingWhen encountering mudstone or highly clayey rock formations, even with the highest flushing flow rate, it is still prone to clogging the hole and causing drilling failure. Such situations are time-consuming and labor-intensive to handle.The LANDSONG JH7 core drilling rig has independently added an external flushing interface at the mud pump location. In case of complex formations, an auxiliary flushing system can be quickly connected externally - the problem of hole clogging is resolved, and the construction in complex formations becomes more confident.
Problem 3: Difficulty in removing the drill pipe → High-torque removal function of the drill pipeUnder high-speed and low-torque conditions, removing the drill pipe often requires the use of pipe wrenches along with manual effort, which is slow and tiring.JH7 has added a high-torque drill pipe removal function. The power head can output greater torque during the removal process, making the process faster and less strenuous. The auxiliary time is significantly reduced, and the efficiency is visibly improved.
Problem 4: Complex operation, slow learning curve → Automatic speed adjustment of the motorManual speed adjustment relies entirely on experience, making it impossible for beginners to master, and even experienced operators cannot do without it.JH7 has upgraded the hydraulic motor automatic speed adjustment system, combining with imported Yagao valve cores. The equipment automatically matches the speed according to the load - the operation is simpler, the response is more sensitive, and both new and experienced operators can easily handle it.
Problem 5: Afraid of overheating during continuous work → Add water coolingDuring hot summer operations, the equipment temperature rises sharply, leaving one feeling uneasy.JH7 has added a water cooling system, which effectively controls the temperature increase. Even during long periods of continuous work, it remains stable and reliable - even on the hottest days, you can work through to the end with peace of mind.
