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.
