• Double Logarithmic Variable Pitch
Helical Mixer Blade: which enables higher charing and discharging speed
and even mixing, eliminates segregation of concrete and is suitable for
the transportation of both dry and wet materials.
• New T-shape Blade
technology. It is made of hard-wearing alloy steel, and thus protects
the mixer blades from abrasion, extends the service life of the agitator
drum, and enhances mixing performance.
• The geometric capacity of
the agitator drum is very large and the filling rate is low, thus
guaranteeing more mixing space. The small inclined angle and low center
of gravity help reducing the possibility of turning-over of the truck.
Closed loop hydraulic system and constant hydraulic oil temperature
controller. Key hydraulic accessories including: Hydraulic plunger pump,
adjuster mechanism with servo, hydraulic motor, and planetary reducer,
all of which are manufactured in world-known brands with stable and
• Pneumatic Water Supply System: The pressure
is provided by the air tank on the chassis with pressure protection
devices. The pressure is provided by the air tank on the chassis with
pressure protection devices. The water inlet connector fits for both
normal water pipe and fire fitting.
• Multi-outlet washing design of
which the cleaning requirements are met with the three fixed pipes for
washing the agitator drum, charging hopper and discharging hopper
respectively, and another flexible water outlet.
operation system: One in the cab to allow control of the agitator drum,
to turn forward and reverse, and to perform the “feed”, “discharging”,
“agitate” and “stop” functions. Two at the rear with one operation
handle at each side to perform “charge”, “accelerate”, “discharge”,
“agitate” and “stop”, all of which are interlocked.
