1. Reduce the frictional resistance of every component.

Carry out the mechanical technique maintenance regulations strictly and lubricate it according to rules, which can reduce the resistance loss of operating mechanism, such as the frictional resistance between drum tyres and the surface of running pulley, the frictional resistance between the supporting axle of running pulley and shaft sleeve and the resistance of hoisting hopper. In this way, the mechanical efficiency improves.

2. Reduce the mechanical invalid load.

The reduction of mechanical invalid load can be realized by taking measures from the processes of charging materials, mixing and discharging materials: put down the charging hopper timely after discharging, which can reduce the energy consumption of vibration. Master the concrete mixer mixing time correctly and discharge materials at the right moment under the condition of ensuring the concrete quality, which can reduce the power consumption.

3. Shorten the time of mechanical test run.

Except for starting the concrete mixer according to operating procedures and the test run time of routine maintenance, in the process of construction, shorten the time of mechanical test run as mush as possible.
