Geological Drilling rig XY44A 1400M


Main Features of Core Drilling Rig:

1. The drilling rig has more speed series (12-level forward rotation and 2-level reversal) and reasonable speed range. The low-speed torque is large (up to 8000N.m), which is suitable for alloy and diamond core drilling, and is also suitable for drilling. Engineering geological survey, hydrological well drilling and foundation pile engineering construction.

2. The vertical shaft through hole diameter is large (93mm), double cylinder hydraulic pressure feeding, long stroke (up to 600mm), strong process adaptability, especially suitable for large diameter drill pipe rope core (upper core) drilling, there are Conducive to improve drilling efficiency.

3. Adopting Tsinghua Wanliyang 6T46 gearbox, this type of gearbox is widely matched on truck models such as Futian, Jianghuai, Kaima and Wuzheng. Mature technology, stable quality, strong overload capacity, after-sales service stations and accessories all over the country.

4. The hydraulic chuck is a disc spring clamp, a hydraulic cylinder release, and a three-cart automatic centering hydraulic chuck.

5. The hydraulic system uses gear oil pump for oil supply. It is easy to install, easy to use, low in power consumption, low in oil temperature and stable in operation. The hand pump is installed in the system. When the power machine is not working, the hand pump can be used to lift the hole in the hole.

6. Power one steam Xichai 92 kW naturally aspirated engine, Guangxi Yuchai 4110 (105 kW) turbocharged engine optional.

7. The center of gravity of the rig is low, the distance of the transfer machine is long (460mm), the fixing is firm, and the stability of high-speed drilling is good.

8. Equipped with anti-vibration instrument, is conducive to grasp the situation inside the hole. Less manipulation and flexible operation.
