Main Features Of Our Crawler Drill Machine
The crawler drill machine comes with four key advantages: full hydraulic drive, ground-touching multi-angle mast, easy operation, and a highly stable structure.
- Full Hydraulic Drive: The system layout is flexible and light. It provides stepless speed regulation, meaning you can run at very high speeds with small vibrations. You can monitor the conditions inside the borehole in real-time through various pressure gauges. This includes a pressure limit protection feature for maximum safety.
- Optimized Whole Machine Structure: It offers high rotation speed, fast footage, and top working efficiency. The telescopic mast design means you do not need to build a separate drill tower, making transport, assembly, and disassembly extremely quick.
- Remote Control Tracking: The crawler chassis uses a remote control system combined with a manual operation lever, which keeps operators safe and makes movement convenient.

High Performance Of Hydraulic Crawler Drill
Our hydraulic crawler drill uses a thin-wall diamond wireline core drilling process. The drill string system has a full, rigid, and straight layout, which provides excellent control over hole deviation.
- The thin-wall diamond bit has small torque resistance and high cutting speeds.
- It delivers a large rock core diameter and an outstanding core recovery rate.
- The overall design minimizes field accidents and increases safety during deep drilling.
If you are dealing with soil layers, the hydraulic crawler drill machine can also add an automatic SPT (Standard Penetration Test) configuration. This test uses a 63.5kg hammer falling freely from a height of 76cm to drive a standard sampler into the soil, helping you judge soil changes and engineering features easily.

Step By Step Working Process Of Our Crawler Drilling Rig
Operating the crawler drilling rig follows six professional steps to ensure successful drilling and core collection:
- Preparation Work: Flatten the ground surface to build a stable foundation. Level the machine itself using professional tools to ensure drilling accuracy. Adjust the mast angle according to engineering needs. Dig a mud pool and connect the mud pump system.
- Casing Installation: Just like building a house needs a strong foundation, the casing pipe must be lowered down until it enters the bedrock. This prevents the soft surface ground layers from collapsing or dropping debris during the drilling process.
- Official Drilling: Lift and connect the double-tube drilling tool assembly to the power head. Turn on the mud pump and start drilling. The standard drill rods are 1.5 meters each. When one rod finishes drilling, the power breakout rises to connect another 1.5-meter rod.
- Core Extraction: When the inner tube is full of rock cores, use the hydraulic winch to lower the overshot lifter down into the drill rod. The lifter grabs the inner tube under gravity, allowing you to pull out the inner tube and extract the rock core samples.
- Sample Recording: Place the collected rock cores in order inside professional core boxes and make detailed written logs. These rock samples are essential archive data for geology exploration.
- Hole Closing: After collecting all necessary samples, pull out the drill rods and casing pipes from the borehole one by one. Use cement to seal the hole and flatten the site to restore its original look.

Common Application Scenarios Of Crawler Mounted Water Well Drilling Rig
Our crawler mounted water well drilling rig is a multi-functional machine. It is widely used in many different professional industries around the world. Because it has a strong tracking chassis and powerful full hydraulic system, it can work perfectly in difficult outdoor environments.
Here are the main fields where our crawler drill machine plays an important role:
- Mineral Exploration: This is the primary use of the machine. It is widely used for the survey and exploration of metal and non-metal solid mineral deposits. It helps geologists get complete cylindrical rock samples from deep underground to find gold, copper, iron, and other valuable minerals.
- Engineering Geological Investigation: Before building large projects like high-rise buildings, big bridges, dams, and highways, engineers must understand the underground soil and rock layers. This hydraulic crawler drill can perform precise core drilling and standard penetration tests (SPT) to check the safety of the ground foundation.
- Hydrogeological Survey: When looking for deep groundwater resources or studying underground water movement, this hydraulic crawler drill machine helps workers drill deep survey holes easily through hard rock and complex soil layers.
- Oil and Gas Field Prospecting: It is also used in the early stages of oil and gas field exploration to gather geological data and rock core samples from underground formations, providing essential information for energy companies.

Crawler-Mounted Water Well Drilling Rig Top 5 Qustions
A: A spindle-type core drilling rig can be used for both rock core exploration and water well drilling, and it is usually suitable for shallow holes under 150 meters. A full hydraulic core drilling rig is designed specifically for deep hole core exploration (mainly wireline coring) and cannot be used to drill regular water wells.
A2: We choose drill bits based on your soil and rock types. For core exploration sampling, we use diamond core bits. For drilling through pure soil layers, we use alloy three-wing bits. For drilling through hard rocks, we recommend roller cone tricone bits or PDC (Polycrystalline Diamond Compact) bits depending on your project budget.
A: If you have a specific coring type requirement, such as NQ, HQ, NTW, or HTW, the dimensions of the matching drill rods, core barrels, and diamond drill bits are standard and fixed as a complete set.
A: If you have a specific coring type requirement, such as NQ, HQ, NTW, or HTW, the dimensions of the matching drill rods, core barrels, and diamond drill bits are standard and fixed as a complete set.
A: No, small lightweight water well machines cannot drill through hard rock layers. They are only suitable for soil layers and soft rock layers. For drilling water wells in hard rock formations, a professional DTH (Down-The-Hole) pneumatic drilling rig is required.
A: You only need to provide three basic details: your required drilling depth, the hole diameter, and the local geological conditions (soil, soft rock, or hard rock). With this information, our engineers can quickly select the most suitable machine model for you.
