Technical specification

Product model: XZ400 horizontal directional drilling machine

Manufacturer: XCMG GROUP

XZ400 horizontal directional drilling machine has the compact structure, excellent performance, complete functions, hydraulic pilot controlled, gear and rack of push-pull. The main performance parameters and control technology has reached the international advanced level. Hydraulic system, power system, walking system and other main parts are picked from the first-class brand products at home and abroad with the good performance and reliability.

The highlights
1. With 179 kw power, itcan ensure the drill in the complex geological conditionsand complete the pipe-laying operation. Meeting china’s 2 engine emissions standards.
2.The gear and rack push and pull, which ensure the stability and the reliability of the transmission of power head.Power head floating and vice floating patent technology can greatly protect the drill pipe thread and improve the service life of the drill pipe.
3.Double speed power head, drillingand dragged back can work when running at low speed, ensuring the smooth construction. Power head can accelerate sliding, reduce the auxiliary time, improve work efficiency.
4.High-power engine systemcan reserve enough and meet the construction of drill rig under different working conditions.
5. Floating vise, the application of my company’s patented technology, can effectively extend the service life of drill pipe.
6. Customersneed diversification.The machine can do automatic (semi-automatic) loading and unloading drill rod device, automatic anchoring system, cab, changes in temperature air conditioning wind, cold start, mud antifreeze, mud cleaning, such as mud throttling device.
The introduction of technology
The hydraulic system

Hydraulic system use a closed loop circuit, hydraulic pilot control, a number of advanced control technologies. The hydraulic components choose from the domestic and international first-class brand with the reliable quality.

The hydraulic oil tank volume

230L

The engine system

Dongfeng cummins turbo engine is powerful, whose emissions meet two stage standards of China:

Engine type	6CTAA8.3-C240
Rated power	179kW
Max. torque	1040 N•m /（1400r/min）
Rated speed	2200 r/min
Standard	Second stage
Main engine fuel tank volume	230L

Chassis

XZ400 adopts high-quality steel tracks (rubber) with strong adaptability and high reliability. The lard cylinder and the frog leg structure have the good stability. Eaton walking speed reducer has the stable performance and walking speed can be up to 3 km/h.

Track outside width	2250mm
Track width	400mm

Roller number	6 units X 2
Driving force	62000kN
Gradability	30%
Walking speed	3km/h
Ground pressure	63.6kPa
Weight	11500kg

Power head

The drilling machine can finish the push and pull through the gear and rack. Power head floating device can effectively protect drill pipe thread. Variable motor can achieve high-speed push and pull.

Max. push and pull speed	0~21m/min
Max. rotating torque	14000N.m

The slurry pump system

Equipped with the large flow slurry pump, it can provide the strong and big flow slurry for construction and guarantee the smooth construction. It can be matched with winter construction mud anti-freeze system and mud cleaning system for the daily maintenance.

Maximum rate of flow	450L/min
Maximum pressure	100bar

Operation desk

Revolving work station can increase the operator visual field and reduce operator fatigue. So the drilling operation is more easy and comfortable.
