XY-44A

XY-44Aspindle core drill rig is an improved product based on XY-42 and X7-44 drilling rigs. Besides all the facilities of XY-42 and XY-44, guide rod structure is adopted on this machine. In addition, this drill equipment is equipped with water brake and manually controlled oil pump.

Features

1. There is more speed grade (8 grades), reasonable speed range and high torque, while it’s low speed max. Torque is up to 3200 N•m (2358 lbf•ft).
2. With large spindle I.D.93mm(3.66 inch), the spindle core drill rig is fed with double hydraulic cylinders with much longer stroke up to600mm(23.62 inch).
3. With strong technological adaptability, the drilling rigs can be adapted on many field, especially on large diameter drill rod drilling, (upper part coring) extracting core with wire line. Thus it is more effective in improving drilling efficiency with less faulty in hole.
4. With low center of gravity and long traveling distance up to460mm(18.1 inch), the drill equipment is reliable and stable in high speed drilling.

Application

Spindle core drill rig is mainly used for core drilling with diamond bit or tungsten-carbide tipped bit. This drilling rigs can also be used for engineering exploration, water well and foundation hole drilling. In addition toChina, it is also exported to South-east Asia,Africacountries.
