CHTC JVD420 Horizontal Directional Driller

Product Feature

       Main Features
Horizontal Directional Drilling Rig has researched base on absorbing domestic and international advanced technology adequately. Unique design, top brands for key parts and also advanced technology make CHTC JOVE Horizontal Directional Drilling Rig reached top international level.
These two models have high reliability, excellent appearance and good assembly craftwork. We adopt hydraulic pilot control and electro-hydraulic control technology, convenience operation. Using Triple pump system ensures reliable performance, easy maintenance and low cost. The push-pull system has strong resistance ability which drives by high pressure gear pump.
The power head adopt double-speed system and ensures high work efficiency.
The compacted appearance insures high across ability, convenient move between jobsites.

Functions
Horizontal Directional Drilling Rig is new underground pipe construction machinery which based on the advanced theory of the trenchless technologies. With whole hydraulic control technologies and power-drive technologies, it achieves drilling, rotating, pushing broaching, pullback, moving and other function easily. It widely used in cross the railway, road, building, river, downtown area, other construction-limited area, agriculture crops, for construction and renewing water supplying, coal gas, electronic, telecommunication, natural gas, etc.

Structure Advantages
Drilling Efficient and Energy Saving

 Engine System
Cummins engine; It can meet complicated jobsites construction demand. The engine also has high reliability and low energy consumption.


Mud System
Adopt model mud pump which has 4 flow quantities and 4 level pressures. So it can meet different diameter holes drill and pullback. The hydraulic motor drives the system, offering high pressure and stable performance.


Travel System
Use the same system like excavator system's support wheel, guide wheel, track idler, driving ring and spring. Rubber crawler has no destroy to the road. Huge torque motor ensures strong grade ability.


Main Boom, Pushing and Pullback Device
The main boom used lift mechanism and ring rail way, which keep the machine's stable operation. And have big approach angle and departing angle. Pushing broaching and pullback device use cylinder and chain structure, offering stable move, huge push force, convenient maintenance and reliable structure.


Main Hydraulic Valves
Adopt imported and reliable high-flow hydraulic valves.


Power Head
The internationally-renowned "Eaton" large torque cycloid motors are used and the power takeoff is much stronger. The two-speed rotation is controlled in the electro-hydraulic way and it is easy to operate.


Clamping Device
The open-loop clamping structure is adopted, making the operation intuitive, convenient, and reliable.


Auto Anchor Device
The automatically-controlled hydromantic anchor device is easy and convenient to operate and is applicable to the work on the mellow ground.


Auto Rod Changing Device 
Optional for auto or half-auto rod changing devices. It is easy to operate, the security is increased, and the labor intensity is greatly decreased.


Engine Bonnet
The integral fiberglass reinforced bonnet is adopted with the streamline form, grace, and beauty. The dual-hinge rotatable structure is adopted and the maintenance is more convenient.


Tools, Pullback Head
The high resistance alloy drilling bits, transfer devices, and integral drill pipes are adopted. Pressure-fed, extruded, cutting, or flow-passage pullback heads can be selected according to the actual situation and will last long.
