Weichai four-cylinder supercharged engine is featured in high fuel efficiency, low emission and large power margin. It is equipped with the driving & steering front axle, maintenance-free wet-type unilateral braking rear axle and four-speed synchronous shift gearbox designed and manufactured specially by CARRARO; its forward and backward directions are switched by electric hydraulic control. The loader working device is an eight-bar automatic leveling mechanism. The bucket is leveled automatically while hoisting, in order to avoid scattering and ensure stable working. The excavator working device can rotate 180 degrees along the gyration center at the back of the frame. The A-shaped stabilizer and the center-positioned excavating device are strong in working stability. Its chassis is an integral type special chassis featured in strong rigidity, impact resistance and compact size. Its cab has a board view and is configured with rail-mounted upturning glass window.
