The machine adds a pressure reducing valve device, which makes it easier to start when the machine starts. No pressure reducing valve, hard to start machine. Boom can be deflected by 60 degrees turning left and right, making the job more flexible. Other factories can only design fix boom or just turn by 30 degrees. Crawlers can be stretched from minimum 32.68 to maximum 39.37 in which and can pass through more narrow places. Other factories’ wheelbases can. Be only designed to fix at 35.83in. The important components on the machine from developed countries: Japan’s main hydraulic pump, Italy’s main valve, Italy’s swing motor and traveling motor. Cooperate with US BRIGGS &STRATTON Engine to meet USA emission demand. Other factories can only use common diesel engines, which can not meet the USA and European emission demand. The hydraulic pipes are all imported from Continental AG Germany Company. Not easy to leak. Other factories use lower quality high pressure pipes, leaks everywhere after working one year. 100 kg counterweight is added to the rear of the machine, which makes the machine work more stable and powerful. The whole vehicle is shot blasted, pickled, phosphates, and sprayed, which increases. The adhesion of the paint molecules, and is more durable, non-bleaching and smoother.
