XYD-3crawler hydraulic core drilling rig
1.Characteristics of XYD-3 crawler hydraulic core drilling rig
XYD-3 crawler hydraulic core drilling rigis mainly used for geological general investigation and exploration,road and tall building foundation exploration,kinds of hole in concrete structure,river levees,subgrade grouting hole drilling and direct grouting,civil wells and earth temperature central air-conditioner,ect.
The drilling rig is equipped with crawler chassis device, which is easy to move with fast speed.
The crawler device is made of resistant steel mill.
Hydraulic oil pressure feed device, which improves drilling efficiency.
Pressure gauge displays the condition of the bottom of the drill hole.
Drill mast controlled by hydraulic cyliner so it improves the efficiency.
Diesel engine adopts the electric starter to reduce the labor usage.
