Product Introduction
As a small horizontal directional drilling rig, the XZ120E is mainly suitable for trenchless laying projects of water, electricity, gas and communication pipelines in urban municipal construction. Its compact structure and flexible mobility enable it to work in construction environments with limited space.
Product Advantage
Power and Transmission: Equipped with a Dongfeng Cummins turbocharged engine, it offers powerful performance.
It adopts the gear rack transmission mode, ensuring a smooth and reliable pushing and pulling process, with a maximum speed of up to 28 m/min.
Core technology: Equipped with patented power head floating and tiger head floating technologies, it can effectively protect the drill pipe thread and extend the service life of the drill pipe.
The adoption of variable piston motors can adapt to different working conditions and enhance construction efficiency.
Control and safety: It adopts a hydraulic pilot control system, which is sensitive in operation and stable in performance.
The overall design of the machine complies with the safety requirements of the EU CE directive, ensuring high construction safety.
Flexible configuration: It can be equipped with various functional modules such as fully automatic or semi-automatic pole mounting devices, heating and cooling air-conditioned cabs, dual automatic anchoring devices, mud anti-freezing and cleaning devices, etc. as needed.

Product Uses
Municipal pipeline network engineering: It is used for the laying and renewal of pipelines such as water supply, gas, electricity, and communication cables, which can effectively avoid the "cutting open" of the road surface and minimize the impact on traffic, the surrounding environment, and citizens' lives to the greatest extent.
Other trenchless construction: It can also be used in geological exploration and other operation scenarios that require horizontal drilling.
Product Operate Guide
Personal protection: Operators must wear personal protective equipment such as safety helmets, protective glasses, and anti-slip gloves.
Emergency response: In case of sudden stuck drill, immediately cut off the power source and try to remove the blockage by rotating in the opposite direction.
If the temperature of the equipment bearings or hydraulic oil is too high (for example, some data suggest that the temperature of the bearings should not exceed 45℃ and that of the hydraulic oil should not exceed 60℃), the machine should be shut down for cooling and inspection.
Drill pipe management: When adding drill pipes, it is recommended that two people work together to ensure that the threads are accurately aligned and avoid thread damage.
FAQ
1.What type of drilling rig is the XZ120E?
It is a horizontal directional drilling rig with a crawler design, which is highly mobile and mainly used for trenchless pipeline laying.
2.What are the core technical features of the XZ120E?
It adopts patented power head floating and tiger head floating technologies, which can effectively protect the drill pipe threads and extend their service life. Meanwhile, its variable piston motor can adapt to various working conditions, enhancing construction efficiency.
3.What devices can this drilling rig be optionally equipped with?
The configuration is highly flexible and can be optionally equipped with fully automatic or semi-automatic pole mounting devices, air-conditioned and heated cabs, dual automatic anchoring devices, mud anti-freezing and cleaning devices, etc. as needed.
4.What safety regulations should be noted when operating the XZ120E?
The whole machine is designed in accordance with the requirements of the EU CE directive, ensuring the safety of construction. In addition, the general key points for safe operation of drilling RIGS include: inspecting high-voltage lines and underground pipelines at the site before operation; Keep the ground level; Operators must wear personal protective equipment such as safety helmets and protective glasses.
5.What checks need to be carried out before starting the drilling rig?
This is a general requirement for drilling RIGS, but it is very important. It is recommended to check the levels of hydraulic oil, engine oil and coolant before starting, ensure that all components are securely connected, clean the operation area and assess the firmness and flatness of the ground.
6.What could be the reasons for the slower lowering speed of the power head?
Possible reasons include: insufficient flow output due to wear of the main pump; The automatic earth-shaking solenoid valve is stuck (often caused by the failure to replace the hydraulic oil in time or the filter element being too old). Or the wire end of the solenoid valve that controls the convergence of the power head is loose, or the fuse is damaged, etc.
