1, Yanmar engine, inline four-stroke, low fuel consumption, low noise, more convenient and environmental protection, maintenance. Engine shroud and left the door can be easily opened, the internal parts repair and maintenance more convenient;
2, imported hydraulic parts, quality, stable and reliable performance. Using load sensing hydraulic control system, making the operation easier, more comfortable, more efficient, lower fuel consumption, with good steering performance composite action;
3, the use of advanced electronic monitoring multifunction large dot matrix LCD display. Electric throttle control system with throttle control, thermal protection, speed of acquisition and other functions, and automatic idle function. In any mode, take full account of the work in fuel economy, can achieve maximum efficiency in all types of job site operations;
4, multi-functional GPS enables remote monitoring and two-way data transfer, real-time control of the machine running;
5, the new cab and seat, vision, excellent safety performance. Seats and interiors, fully consider ergonomic, improving operator comfort;
6, strengthen working device, using thicker plates, optimizing welded structures, and in the areas of stress concentration using special steel plate welded to dramatically improve its reliability.
