Cleaning and maintenance items after each work is completed

  • Clean the inside and outside of the mixing drum, the discharge door, the feeding rack and the chassis, and rinse with water.
  • Each lubrication point must be filled with lubricating oil.
  • After shutdown, the air switch should be disconnected.
  • The water stored in the air storage cylinder of the air compressor should be drained (pay special attention when the weather is humid.
  • Plug the air-conditioning section, drain the water in each water pump, open the water inlet check valve, and drain the water in the water inlet pipe. Then, turn the water pump operation switch one or two times to make the water pump run for one or two times. In two minutes, remove all the water in the waterway system.
  • The additive storage tank should be rinsed with clean water.

Weekly inspection and maintenance items

  • Check the cementation of the residual concrete in the mixing drum, the discharge door, the feeding rack and the chassis. In addition to washing with water, if necessary, cut off the power supply and remove the residual cement manually.
  • Check the tension of the wire.
  • Check whether the solenoid valve is leaking, and whether each cylinder operates normally.
  • Check the quality of the lubricating oil and the height of the liquid level of each gearbox.
  • Add grease to each grease nipple and check whether the grease nipple is blocked.
  • Check whether the travel limiter is loose and the movement is accurate. If there is looseness or the action is ahead or behind, necessary adjustments should be made.
