GDL-350 Top drive Drill Rig
ABOUT GDL-350 DRILL RIG:
This drilling rig is a versatile water well drilling equipment that combines the capabilities of water drilling and air drilling. It features a vehicle-mounted 525 gearbox, providing smooth and efficient gear shifting. Compared to hydraulic transmission, the gearbox offers double the transmission efficiency and reduces power consumption by 35%, making it highly energy-efficient.
This drilling rig effectively addresses the challenges faced during air DTH hammer drilling in soil layers and the low construction efficiency of rotary drilling rigs in hard rock layers, gravel, and pebble layers. It offers a comprehensive solution by enhancing drilling performance and efficiency in various geological conditions.
Main features:
1. The drill speed can reach 27-901r/min, and the maximum output torque is 10500N.m.
2. The drilling rig adopts a long-stroke double-speed mechanism, a mechanical power head, and a power head stroke of 3500mm, which is used to improve drilling efficiency and reduce the occurrence of drill blocking and burning accidents.
3. The drilling rig adopts double oil pumps for oil supply. A single pump is used when drilling, and two pumps are used for confluence when lifting and lowering the drill. The power loss is small and the auxiliary time is short.
4. The crawler chassis is adopted, and the outrigger cylinder stroke is 1.5m, which can be loaded automatically, which is convenient for relocation and transportation.
5. The drilling rig reserves some functional interfaces in the mechanical and hydraulic systems, which can be expanded according to the technological requirements of different users.
