Product parameters

LG7220 is a product of high speed, high efficiency, high accuracy and multiple purposes developed by LTXG on the basis of advanced technology of European, can be used for ground leveling and grooving, scraping slope,bulldozing, ploughing snow, loosening, compacting, material arrangement and mixing works, and is widely applied in construction operating condition of road, airport, defence engineering, mine construction, road construction,water conservancy construction and farmland improvement and so on.

1,Adopted 6CTA8.3 of CUMMINS engine which match perfectly with ZF6WG200 thus to realize optimum capability and fuel efficiency.

2,Swing frame is made of lubrication-free and maintenance-free composite bearing, with small frictional coefficient, high reliability and is shock-proof and water-proof; Hydraulic lock cylinder location is adopted and is easy to operate.

3,The cab is fully sealed and optimized by ergonomics. It is spacious and bright, and good sealing effect. With wide visual field, operators can see the front wheel and the blade clearly thus to improve the operating precision.

4,Electrical system of the entire machine has centralized control, three-stage alarm electronic monitoring system, digitalized stepping instrument display, high man-machine interaction and is convenient for detection and maintenance; The entire machine control has automatic cruise function, which can get engine operated in setting speed and thus reduces the labor strength of operation person.

5,It is applied with the dual cylinder-driven pallet-type working device of European advanced technology, helping to realize large driving force and high reliability. The blade can rotate with load, which is domestic industrial originated, can provide precise operation.

6,Flexible hydraulic control system with two sets of HUSCO five way control valve, import hydraulic equalizing valve for the blade lifting,Patent hydraulically-operated pin drawing device is designed firstly in board.

7,It is optional for front bulldozing plate and rear ripper.
