GDL-280 Top Drive Drill Rig Machines 200m Depth 152mm Hole

ABOUT GDL-280 DRILL RIG:

The drilling rig is a water well drilling equipment that integrates water drilling and air drilling functions. The drilling rig adopts a vehicle-mounted 525 gearbox, which is sensitive and convenient to switch gears. The transmission efficiency is doubled compared with hydraulic transmission, and the power consumption is reduced by 35%., which is energy efficienctly. It solves the difficult problems of air DTH hammer drilling in soil layers and low construction efficiency of rotary drilling rigs for hard rock layers, gravel and pebble layers.

Main features:

1. The drill speed can reach 33-1120r/min, and the maximum output torque is 9800N.m.

2. The drilling rig adopts a long-stroke double-speed mechanism, a mechanical power head, and a power head stroke of 2300mm, 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.

Applications:

1: Core drilling NQ/HQ/PQ

2: Air drilling + DTH hammer

3: Mud drilling with mud pump
