1, The concrete mixers should be set in flat position, with a wooden mat under the axle, so that the tire is put overhead, so as not to move around in the operation.
2, The concrete mixer should be the implementation of two leakage protection, after the power supply connected, must be carefully checked, the empty car trial to make sure it’s normal before use. When the test run should check whether the rotating speed is appropriate, under normal circumstances, the empty speed is slightly faster 2 to 3 turn than the vehicle (after loading), if the difference is too much, should adjust the ratio of the wheel and transmission wheel.
3, The rotation direction of the mixing cylinder should be consistent with the direction of the arrow, if it is not, should correct the motor wiring.
4, Check whether the transmission clutch and brake is flexible and reliable, whether there is the damage on the rope, the track pulley is good, there are obstacles around the lubrication of various parts and so on.
5, After the starting, often pay attention to whether the operation of various parts of the concrete mixer is normal. When shutting down, always check whether the concrete mixer blade is bending, the screw has been knocked off or loose.
6, When the concrete is finished mixing or is expected to stop more than 1h, the remaining material need to be cleaned out, use stones and water into the shaker, the boot turn, wash and discharge the motor stick on the barrel. There should be no water in the barrel, so as to avoid barrel and leaf rust. At the same time should clean the mixing tube fouling, so that the machine keep clean and intact.
7, After get off work and stop the concrete mixers, should be powered off, and lock the switch box to ensure safety.
