Oil and circuit and control equipment inspection at
the lubrication, adding oil as required. Before each shift, water in the mixing
bucket idle 1-2 minutes, check the clutch and brake device reliability of
the work. Concrete mixer during operation and preparation check if motor
seized, reducers, gear noise is normal, the temperature rise is too high. After
completion of the work shifts should be carefully cleaned concrete mixer. A
concrete mixer general maintenance work after 100h for primary care.
1, concrete
mixer in the primary care, in addition to including the content of the work
routine maintenance, but still need dismantling the clutch, check and adjust
the brake clearance, such as the clutch inner and outer brake band wear off
even be replaced. Also check the rope, V belt bearing, water distribution
systems and running wheel.
2. compulsory concrete mixer at maintenance level,
the gap between the blades should be checked and adjusted stirring blade and
the liner between the hopper and the discharge door seals and flexible, the
degree of wear of the clutch of the normal level of the water distribution
system algorithm.
3. Using a rotating concrete mixer chain need to check chain
pitch elongation case two maintenance concrete mixers two maintenance cycle is
generally 700 ~ 1500h hours of work, two maintenance in addition to a
work-maintained, shall be demolished check reducer, motor and open gears, etc.
Also you need to check the machine and the operating mechanism of the material,
cleaning the road wheels and the steering mechanism.
