XY-280 Core Drilling Rig 280m Depth Vertical Shaft 59mm
XY-280 drilling rig is type of vertical shaft drill. It equips L28 diesel motor which is made from CHANGCHAI 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.
Main 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 engineering 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 labor force.
8. Six speeds gearbox, wide speeds range.
9. The spindle has the octagon section so give more torque.
