GDL-350 Borehole Drilling and Wireline Sampling Multifunctional Exploration Drilling Rigs
ABOUT GDL-350 DRILL RIG:
GDL-350 Multifunctional Exploration Drilling Rigs are both available for borehole water well drilling and rock sampling. It can be used for mud pump drilling, DTH air drilling and wireline core drilling.
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.
