Concrete Mix Truck was used to transport construction concrete of special truck; cylindrical mixing drum to carry the concrete mixed on trucks. During transport always kept stirring drum rotation to ensure that concrete does not carry solidification. After the delivery of finished concrete, usually rinsed with water inside the mixing drum, to prevent residual concrete hardening space, so the volume of the mixing tube is less and less.
Concrete mixer truck device component by truck chassis system and the concrete mixing system . China's production of concrete mixer truck chassis to use more vehicle manufacturers to provide two types of GM chassis. Its special mechanism includes power take off, mixing drum frame, gearbox, hydraulic systems, the mixing tube, the control mechanism, cleaning system.
Working principle is that by PTO take out Truck chassis power,
and drive hydraulic system of the variable pump, the mechanical energy into
hydraulic energy to quantitative motor, motor and drive reducer, reducer drive mixing plant, for mixing concrete. Concrete Mix Truck Concrete Mix Truck,Concrete Pump Truck,Concrete Mixture Truck Suizhou lishen special vehicle co.,ltd , http://www.ls-truck.com
