Application
The YGSL-120R hydraulic dual top drive crawler geothermal crawler drilling rig is ideal for a variety of drilling methods and ground conditions, especially the non-compacted ground layer, the gravel layer, and the fragmented rock stratum.
It is widely used in the boring of not only the GSHPs hole, water well, and water exploration hole, but it also creates the drainage hole and large tonnage pre-stressed anchorage holes for various geotechnical engineering projects, including side-slope construction of dams, railways and highways, and more. In addition, it can be used for pipe shed drilling in underground engineering projects, grouting reinforcement hole drilling, small foundation pile boreholes, and making holes for landslide disaster and rock collapse prevention projects.

Features
1. The hydraulic dual top drive crawler geothermal crawler drilling rig is equipped with a front and a rear power head, which makes a variety of drilling methods possible. For instance, it can achieve single rotating drilling for both inner and outer drilling tools, and it also achieve rotating drilling for inner drilling tools and reverse drilling for the outer casing.
2. There are two levels (high speed and low speed) of rotary speed output. The rotary speed can be steplessly adjusted in rating speed range of each level, which makes the drill suitable for a variety of boring methods and techniques, such as rotary drilling, impact drilling (Down-the-hole Hammer drilling), impact and rotary drilling, auger drilling and so on.
3. Designed with large rotational torque and long feed travel, the drilling rig provides a fast drilling speed. In addition, the safety and the hole-making efficiency of the equipment is greatly improved.
4. The drilling rig comes with a crawler track type chassis. This makes machine moving and hole positioning convenient and fast, thus saving time while moving from one drilling task to another at one work site.
5. Equipped with internationally famous brands of hydraulic pumps, motors and operating valves, our machinery provides stable and reliable performance and has a long service life.
6. The drilling rig is installed with hydraulic wrenching and clamping devices, which make clamping and loosening of drilling tools quick, convenient and dependable. This design also enormously reduces the labor for operators during drilling.
7. Our equipment features a modular design, ensuring convenient transportation. In addition, a Lineate Remote Moving Control Device and Safety Emergency Stop Switch are available upon request.
