Crawler Core Drilling Rig

Series spindie type core drilling rigs are mounted on the crawlers, which is a portable hydraulic rig on high speed. These drills move easily with hydraulic feeding

We can design and manufacture drilling rigs and piling machine according to customers requirements.

Series spindie type core drilling rigs are mounted on the crawlers, which is a portable hydraulic rig on high speed. These drills move easily with hydraulic feeding

Application Range

Engineering geological explorations for railway, hydropower. highway, bridge and dam etc; Geologic core drilling and geophysical exploration; Drill the holes for small grouting and blasting

Structural Configuration

The drilling rig includes crawler chassis, diesel engine and drilling main body; all these parts will be mounted on one frame. The diesel engine drives drill, hydraulic oil pump and crawler chassis, the power will be transferred to drill and crawler chassis through transfer case.

Main Features

(1) Being equipped with rubber crawler make the drilling rig moving easily. At the same time, the rubber crawlers won't destroy the ground, so this kind of drilling rig will be convenient for construction in city.

(2)Being equipped with hydraulic oil pressure feeding system improves drilling efficiency and reduces labor intensity

(3)Being equipped with ball type holding device and hexagonal Kelly, it can accomplish no-stopping working while lifting the rods and get a high drilling efficiency. Operate with convenience, security and reliability.

(4)Through the pressure indicator of bottom hole, the well condition can be observed easily

(5)Having hydraulic mast, convenient operation.

(6)Close levers, convenient operation.

(7)The diesel engine starts by the electromotor.
