XY-44A Geological Core Drilling Rig with Crawler

Product Introduction

Key features of the XY-44A core drill rig

1. with more speed series (12 level positive turn 2 level reverse) and reasonable speed range, low speed torque (up to 8000N.m), not only suitable for alloy, diamond core drilling, but also suitable for engineering geological investigation, hydrologic well drilling and foundation pile engineering construction.
2. vertical shaft through hole diameter (93mm), double cylinder hydraulic feed, long stroke (up to 600mm), strong process adaptability, especially suitable for large diameter drill pipe rope coring (upper coring) drilling, conducive to improving drilling efficiency.
3. Adopt Tsinghua Wanliyang 6T46 transmission, which is widely matched in Foton, Jianghuai, Kaima, Wuzheng and other truck models. Mature technology, stable quality, overload capacity, after-sales service stations and accessories throughout the country.
4. hydraulic chuck for disc spring clamping, hydraulic cylinder loosening, three slips automatic centering type hydraulic chuck.
5. hydraulic system adopts gear oil pump oil supply, simple installation, easy to use, less power consumption, hydraulic system oil temperature is low, stable work. The system is equipped with a hand oil pump, when the engine can not work, the hand oil pump can still be used to pull out the hole inside the drilling tool.
6. the power of FAW Tin Chai 4110 (81 kW) naturally aspirated engine, Guangxi Yuchai 4110 (105 kW) turbocharged engine is optional.
7. Low center of gravity of drilling machine, long shifting distance (460mm), fixed firmly, high speed drilling stability.
8. equipped with shockproof instrument, conducive to the control of the hole. Less handling handle, flexible handling.
9. the crawler chassis, leg cylinder travel 1.5m can be automatically loaded, easy to move and transport.

Main applications
The series of core drilling rigs are mainly suitable for industries such as geology, metallurgy, coal, hydrology and engineering, but also for engineering geological exploration, shallow oil and gas exploration, mine tunnel ventilation, drainage, drilling of hydrologic wells and construction of large diameter foundation piles.
