WG180 Wheel Trench & Tunnel Excavator

Wheel Trencher is one of the most important large machinery of army. With high flexibility and working efficiency, this earth-digging machine can keep working for a long time, and it is mostly used in the digging of trench, transporting trench as well as the flat-bottoming tunnel of field work. The main working area is the plain and gravelly plant. For the appearance and traveling status, you may check picture 1-1, transporting status: picture 1-2 and operating status: picture 1-3.

Application

Wheel Trench & Tunnel Excavator is mostly used in the digging of chasm trench, transporting trench as well as the flat-bottoming tunnel of field work. There is a supplemental dozing scraper in the front of the machine, which can be used to flatting the operating area, tidying the in-and-out road and fill the bottom tunnel back.

Applicability

Applicable in area with a transverse gradient no more than 10 degree, lengthways gradient no more than 10 degree, and the earth grade should be from I to IV. There shouldn’t be any single stone larger than 10cm× 10cm and adulterating stone lager than 5cm×5cm, and the percentage of adulterating stone should be no more than 30%.

Constitutes

Wheel Trench & Tunnel Excavator is mainly made up of the basic vehicle and the working device. The basic vehicle is wheel articulated and formed by a front and a rear frame, driving cab, transmission system, working device, hydraulic system, general electronics, working device electric system, air-conditioning system and controlling system.

The steering is driven by a mechanical and hydraulic system, and the working device is completely driven by a hydraulic system. The controlling set was an integration of mechanical, electrical and hydraulic system, and the working device can be remotely controlled.
