1. Rotary speed ranges 33-1120r/min, and the maximum output torque is 9800N.m
2. The drilling rig adopts a long-stroke double-speed mechanism, a mechanical drilling head, and a stroke of 200MM, which is used to improve drilling efficiency and reduce drilling pipe getting stuck
3. The drilling rig adopts double hydraulic pumps for oil supply,  single pump is used when drilling, and a double pump is used for confluence when lifting and lowering the drill; In that way,  reduce power loss and save time.
4. The crawler chassis is adopted, and the outrigger cylinder can be automatically loaded with a stroke of 1.5m, which is convenient for relocation and transportation
5. The drilling rig reserves some functional interfaces in the mechanical and hydraulic system, which can be expanded according to the technological requirements of different users

JDL-280 is a mechanical transmission top-drive drilling rig, it is widely used for exploration drilling, wie line core drilling,( NQ, HQ, PQ), water well drilling, geothermal well. It has Rpn 33-1120Rpm, this is good for all kinds of drilling methods, and it can even do air drilling when work with air compressor. A true multi-function drilling rig。
