XY-4A Mine drill rig:

adapt to the needs of the current geological exploration ,develop a new product XY-4A type prospecting rig which based on a drilling capacity of XY-4 core drill. Addition to the main use in alloys, diamond core drilling, also be used for engineering geological survey,

Hydrology and water well drilling, as well as large-caliber foundation construction. It is reasonable structure, light weight, large capacity, versatile, stable performance, reliability, standardization, high level of generalization.

Main features:

1, has more speed series (8) and reasonable speed range, low-speed torque (maximum reached 3200N.m). Both suitable alloy, diamond core drilling, can also be used for engineering geological survey, hydrology and water well drilling into the foundation piles construction.

2, hanging scroll through holes large diameter (80mm), double cylinder hydraulic feed, the trip is longer (up to 600mm) process adaptability, especially for large diameter drill pipe rope core (upper coring) drilling, is conducive to improve drilling efficiency and reduce holes accident.

Drilling capacity diameter 71mm rope core drill pipe rated drilling depth of up to 1000m.

Light weight Detachable good, rig Net Weight 2150kg, the host can be decomposed into 10 components (maximum removable parts weight 300kg), removal convenient, appropriate for the mountain areas.

With water brake, deep hole drilling, drilling down smooth and safe.

6, Single Gear oil pump, simple to install, easy to use, less power consumption, the hydraulic system oil temperature is low and stable work. The system is equipped with a hand pump, can be used when the power does not work from the hand pump hole drilling.

Rig structure is compact and reasonable layout, all components revealed outside, do not overlap, ease of maintenance, maintenance and repair.

8, low center of gravity shift car long distance (up to 460mm) fixed firmly, and high-speed drilling and good stability.

9 with shockproof instrument, instrument life long conducive to grasp hole situation, manipulation handle less manipulation of a flexible and reliable.
