XY-4 Drilling rig

XY-4 is a shallow/middle-hole core drill. It is applicable to not only the core drilling of small or big diameter with carbide and diamond bits, but also the engineering geological exploration and the construction engineering, hydropower engineering, highway/railway construction, port construction, etc.

1. The drilling rig is characterized by higher rotation speeds and rational speed range, a bigger range for speed grade and bigger lower-speed torque, it’s applicable to the small-diameter core drilling with diamond bits,and it can also meet the requirements of the big-diameters core drilling with hard alloy bits and various engineering hole drilling
2. It’s adopts vehicle transmission case and clutch ,with simple structure and rational layout, All parts are exposed, without overlapping ,easy to maintenance, serving and repair.
3. It has two-gear reverse speeds for dealing with the accident in the hole,with lower labor strength and safe operation.
4. Its hydraulic gear pump adopts the vehicle-specific oil pump, which is directly suspended on the transmission case, with compact structure and easy for disassembly and repair.
5. The drill rig is light in weight, easy to be disassembled and moved and available to the operation in mountainous area.
6. It’s equipped with sufficient instruments, which is in favor of mastering the situation in hole, with a few operating handles and characterized by rational layout and flexible and reliable operation.
7. The machine can moved steadily and fixed firmly, its frame is solid, with a lower gravity center and good stability during the high-speed drilling
8. The hydraulic plunger chuck is adopted, with reliable clamping operation and free from damaging the drive pipe
