Product Description

XZ720E HDD Technical Specification

Model: XZ720E Horizontal Directional Drill(HDD)
Manufacturer:XUGONG Foundation Construction Machinery Group Co.; Ltd.
 

Xz720e horizontal directional drilling rig is an integrated full self-contained design, which adopts a number of advanced control technologies such as closed energy-saving circuit, hydraulic pilot control and load sensitive control, as well as the company's proprietary technology. The main performance parameters and control technology have reached the domestic leading level. The main components of hydraulic system, transmission system, reducer and electrical control system are domestic and foreign brand products with reliable quality.

I.Features Introduction

1.It adopts many advanced control technologies, such as closed energy-saving circuit, load sensitive control, electro-hydraulic proportional control, imported components and reliable quality;
2.The pushing& pulling of the gear rack ensures the stability of the power head and the reliability of the transmission. The floating of the power head can greatly protect the drill pipe thread and improve the service life of the drill pipe;

3.The high-speed and low-speed push-pull rotation system and the plunger variable motor realize the high-speed and low-speed push-pull of the power head, increase the adaptability to the working conditions of the drilling rig and improve the construction efficiency of the drilling rig;

4.The pushing$pulling and rotation adopt multi stager output technology, and the engine adopts high-pressure common rail and full electronic control module technology, so the system is energy-saving and efficient construction;
5.The whole machine has a wide field of vision, single / double handle mode and wire controlled proportional walking system, with comfortable, efficient and safe operation;
6.It can be equipped with semi-automatic drill pipe loading and unloading device, which can greatly improve the construction efficiency and reduce the labor intensity;
