Product Description
Crawler rope core drilling rig is a kind of drilling equipment that combines crawler walking mechanism and rope core technology, with the following characteristics:
- **Walking mode**: Crawler walking mechanism is adopted, similar to crawler construction machinery vehicles. The steel track makes it able to adapt to complex terrain, such as rugged mountain roads, muddy ground, steep slopes, etc., with strong field passing ability, flexible mobile transition, and some drilling rigs have a single climbing ability of up to 45°, and the walking speed is generally about 2 - 3.5km/h.
- **Core Extraction Technology**: Using rope core technology, after the core is filled with core pipe during the drilling process, there is no need to lift the core for drilling, and the drill pipe is used as a channel to lift the core outside the hole with the help of rope and special fishing tools. This method reduces the number of lifts, saves time, improves drilling efficiency, and maintains core integrity and original structure.
- **Power & Transmission**: Usually powered by a more powerful engine (e.g. 76kW - 154kW and other different specifications). The full hydraulic transmission system is mostly adopted, and the main actions such as rotation, propulsion and lifting of the drilling rig are driven and controlled by the hydraulic system, and it has an automatic hydraulic feeding mechanism, which can automatically control the feed speed and pressure of the drill pipe. Some drilling rigs adopt multi-pump combined hydraulic system, multi-speed hydraulic control for rotation and propulsion, and can flexibly adjust the speed ratio according to different geological conditions.
- **Structural Composition**:
- Powertrain: The engine that powers the rig.
- Slewing system: The parts that rotate the drill pipe and drill bit, such as turntables, faucets, etc.
- **Feed system**: a device to control the feed of the drill pipe, with a hydraulic feed mechanism, etc.
- **Lifting system**: including winches, etc., used for lifting and unloading drilling tools, etc., some winches have structural improvements such as cages to withstand impacts.
- **Coring system**: The core part, which consists of a core drill bit, core tube, rope fisher, etc.
- **Crawler chassis**: support the whole machine and realize the walking function, some may have auxiliary devices such as outrigger cylinders to facilitate loading and other operations.
- **Application field**: It is widely used in geological exploration (including survey exploration, geophysical exploration, etc.), mining, hydrogeological survey, engineering geological survey (such as road and building exploration) and drilling projects such as blasting holes.
- **Performance parameters**: Different types of drilling rigs have different drilling depths and diameters, ranging from hundreds of meters to thousands of meters, such as RL400X drilling depth of 400 meters, RL1000XL drilling depth of 500 - 1000 - 1100 meters, etc.; Parameters such as lifting force, slewing torque, and feed stroke also vary depending on the model.

Our Advantage
1. Full hydraulic control is convenient and flexible
It can adjust the speed, torque, propulsion axial pressure, anti-axial pressure, propulsion speed, lifting speed of the drilling rig at any time, as well as the stylized experience value rig parameter matching program. To meet the needs of different drilling tool operating conditions and different construction technologies.
2. Top drive rotary propulsion lift
Top drive power head has anti-impact design patented technology, rotary gear reducer reliable and durable, direct access to the drill pipe, shorten the auxiliary time, but also conducive to pipe drilling.
3. Multifunctional drilling
Various drilling processes can be used on this drilling rig, such as: down-the-hole drilling, through-air reverse circulation drilling, gas lift reverse circulation drilling, cutting drilling, roller cone drilling, heel drilling and core drilling, etc. The drilling rig can be equipped with mud pumps, foam pumps, generators or sampling equipment according to user requests. The drilling rig also comes standard with various winches.
5. High work efficiency
All kinds of centering devices, rod feeding mechanisms, rod unloaders, lifters, anti-sludge one-way check valves, centralizers, low-temperature start-ups, specialized air filters, etc., are suitable for various drilling processes and the requirements of different use environments. They are easy to control and flexible, with fast drilling speed and short auxiliary time. Therefore, the operation efficiency is high and the risk of construction accidents is reduced.
6. High outright crawler
The high outriggers are easy to load and transport, and can be loaded directly without a crane. Tracked walking is more suitable for muddy on-site movement.
7. Unique Adjustment of Positive and Negative Axial Pressure for Full Hydraulic Drilling Rig
All kinds of impactors want to achieve higher impact efficiency have their matching better axial pressure and speed. During the drilling process, with the increasing number of drill pipes, the axial pressure on the impactor is also increasing. Therefore, during construction, the positive and negative axial pressure valves are adjusted to ensure that the impactor can obtain a more matching axial pressure. At this time, the impact efficiency is higher.
8. Efficient and durable oil mist dispensers and pumps
During the drilling process, the high-speed impactor is lubricated at all times to extend its service life to the greatest extent.
