Introduction du produit

Le couple de sortie maximal est de 150 kN.M, la profondeur de forage maximale peut atteindre 52 m et le diamètre du forage de la machine peut également atteindre 1300 mm. Le mécanisme de luffing monocylindre de cette machine a un fonctionnement stable et est très facile à entretenir et à réparer. The two-segment masts have also been optimized to achieve automatic butt joints and folds, improving efficiency, and helping customers to worry less.In addition, the drilling depth measurement system has been innovated, which has higher accuracy than that of ordinary rigs. The main hoist bottoming protection device (a device that will alarm if the inverted mast is close to the ground) effectively reduces the difficulty of operation and makes the machine Handy when operating machines. The keys of the power head can be used in both directions, and they can continue to be used while they are worn and the other side, which doubles their service life.Very high safety performance, in strict accordance with EU safety standards, meet dynamic and static stability requirements, and ensure safety during construction.Low emissions, environmental protection and energy saving, meet the requirements of most developing and developed countries.The following is an introduction to an engineering case.
This project “power system underground pipe corridor project” is located in Nanjing.The project need construct under the high voltage line, so there is high limited requirement. La plate-forme de forage rotatif est personnalisée. En raison des exigences relativement élevées du client en matière d'équipement mécanique et de la gestion des conditions géologiques complexes. The geology of this project is mainly soil layer, weathered rock, drilling diameter 800mm, drilling depth 15m, hole forming time is about 25 minutes, in general, 10 hours construction forms 21 holes, also with hanging steel cage in the middle. Former l'efficacité des trous ainsi que les performances de la machine pour obtenir la reconnaissance des clients.
