Concrete mixer truck is a special truck used to transport concrete for construction. Due to its shape, it is also often called a snail truck. These trucks are equipped with cylindrical mixing cylinders to carry mixed concrete. During transportation, the mixing drum will always be kept rotating to ensure that the concrete carried will not solidify. After the concrete is transported, the inside of the mixing drum is usually flushed with water to prevent the hardened concrete from occupying space and reducing the volume of the mixing drum.
Concrete mixer is composed of chassis, mixing drum, transmission system, water supply device, etc. Due to the technical bottleneck, the four major parts of the domestic mixer are all imported parts.
Composition of mixer: Class II chassis, transmission system, hydraulic system, frame, mixing tank, feeding and discharging device, water supply system, control system, man ladder, etc. The front end of the mixing tank and the reducer are connected and installed on the front of the rack, and the rear end is supported by two supporting wheels installed on the back of the rack through the raceway.
The chassis of the concrete mixer trucks produced are mostly Class II general chassis provided by the vehicle manufacturer. Its special mechanism mainly includes power take-off, front and rear supports of mixing cylinder, reducer, hydraulic system, mixing cylinder, operating mechanism, cleaning system, etc. The working principle is to take out the power of the automobile chassis through the power take-off device, drive the variable pump of the hydraulic system, convert the mechanical energy into hydraulic energy, and transmit it to the quantitative motor. The motor drives the reducer, and the reducer drives the mixing device to mix the concrete.
Before daily operation, check whether the oil level of the hydraulic oil tank meets the requirements and whether the water in the water tank is replenished. After operation, the vehicle shall be cleaned and inspected, and the water in the water tank shall be emptied in time to avoid freezing the water tank in winter.
In addition, it is also necessary to regularly check the fastening condition of the upper mounting bolts, regularly check the cleanliness of the hydraulic oil filter element, and regularly lubricate the lubrication points of the upper mounting transmission parts. Replace the hydraulic oil filter element every three months or 10000 km, and check whether the hydraulic oil is emulsified. The gear oil of the reducer shall be replaced once a year.
Regular maintenance can effectively improve the service life of the upper hydraulic system and ensure the attendance rate of vehicles. Of course, it also reduces maintenance costs and improves efficiency. Come to our website for more information Consult.
