Its layout is well designed ,its appearance is nice and modern ,it has a high working performance and is reliable in safety . The machine has used in civil industry widely including large mine ground, port, electricity, road building and been exported to lots of countries in South-east Asia, the Middle East, Africa, America and so on.

1. Machine is well designed overall with good performance .
2. Engine has a high reserved power rate , high torque rate with lower fuel consumption .
3. Hydraulic power transferred ,automatic transmission without phased shifting .
4.Final drive use triangle spline and hobbing drum type gears , which improve the loading evenness and stability to own a long life .
5. Design of operation is combined with humanity ,levels are placed in the two sides of operator, which makes the operating convenient .
6. New type ROPS-FOPS is well equipped making the appearance more better .
7. 3-element,single phased torque converter has high efficiency and high capacity .
8. Hexagon cabin ensure wider eye-sight .
9.Various options: ROPS-FOPS cabin ,normal cabin , air-conditioned cabin ,warm heater , Diethyl ether starter, angle blade, straight-tilt blade ,U-blade, garage blade .
