XY-280 Core Drilling Rig Introduction:

XY-280 drilling rig is type of vertical shaft drill. It equips L28 diesel motor which is made from Changzhou diesel engine factory. It is mainly used for diamond bit drilling and carbide bit drilling of solid bed. It also can be used in exploring drilling and base or pile hole drilling.
Drill Rigs Features:

1.compact size and light in weight of mechanical transmission, major diameter of vertical shaft, long distance of support span and good rigidity, hexagonal Kelly ensure the torque transfer.
2.High speed and suitable range of speed to meet varies need of small diameter diamond bit drilling, big carbide bit drilling and all kinds of the engineer holes.
3. Hydraulic systems can adjust the feeding pressure and the speed, so it can satisfy the drilling in various stratums .
4.Pressure gauging can make you get the information about the feeding pressure at the end of the hole.
5.Transmission and clutch of Automobile are choice in order to achieve the good generalization, easy repairing and maintenance.
6.Close levers, convenient operation.
7. motor start by electricity, reduce labour force.
8.The spindle has the octagon section so give more torgue.
Application:

1. With hydraulic automatic feeding device, elevated drilling efficiency.

2. The holding mechanism with upper spherical jaws is used as substitute for chuck. The rod can be replaced without shutdown.

3. Centralized handles, easy operation, safe and reliable.

4. The drilling machine, pump and diesel engine are installed on a common base frame in order to have a compact structure and occupy small field area.

5 lightweight, high detachability, easy transportation and suitable for the operations in plains or mountain areas..
