Concrete pump trucks play an important role in construction. Correct maintenance can extend their service life, improve work efficiency and ensure construction safety.
After each operation, the body, hopper, delivery pipe and other parts of the pump truck should be cleaned in time to remove the remaining concrete. A high-pressure water gun can be used for flushing, but direct flushing of electrical components and hydraulic systems should be avoided. At the same time, clean the cab regularly to keep the interior clean and create a good working environment for the driver. Check the levels of hydraulic oil, lubricating oil, fuel and other oils every day to ensure they are within the normal range. If the level is too low, add the corresponding oil in time. Also observe the color and transparency of the oil. If any abnormality is found, replace it in time. And pay attention to checking whether there is any oil leakage.
Checking tires is also very important. Ensure that the tire pressure is normal and there is no damage or excessive wear. Inflate in time if the pressure is insufficient. Repair or replace in time if there is damage. The outriggers of the pump truck also need to be checked to see if they are firm and whether there is any deformation or damage. Before operation, make sure that the outriggers are fully extended and supported on a solid ground. Checking the electrical system should not be sloppy. Ensure that the lights, instruments, horns and other components of the pump truck work normally. Eliminate faults in time. At the same time, check whether the wires and plugs are loose or damaged to prevent electrical accidents. According to the requirements of the equipment operation manual, replace hydraulic oil filters, air filters, fuel filters and other components regularly. The filter can filter impurities in the oil and air to prevent them from entering the system and damaging the equipment. When replacing the filter, choose a reliable product and install it in strict accordance with the operating procedures. Regularly check the pressure, flow rate, temperature and other parameters of the hydraulic system to ensure they are within the normal range. Find the cause and repair in time if any abnormality is found. Check whether there is any leakage in hydraulic pipelines, joints, cylinders and other parts. Deal with it in time if there is leakage. At the same time, pay attention to checking the cleanliness of hydraulic oil and replace it in time if it is seriously polluted.
Regularly check the wear of components such as the piston, delivery pipe, spectacle plate and cutting ring of the pumping system. Replace in time if there is wear. Check the tightness of the pumping system to ensure that the concrete will not leak during the pumping process. Also pay attention to checking the pressure and flow rate of the pumping system and adjust in time if there is any abnormality. Lubricate each lubrication point of the pump truck regularly, such as the transmission shaft, joint bearings, delivery pipe support wheels and so on. Use suitable lubricating oil to ensure good lubrication effect. Pay attention to the filling amount of lubricating grease. It should not be too much or too little. Too much will cause waste and pollution, and too little will not play a good lubricating role. During winter maintenance, pay attention to cold protection and insulation. Wrap the hydraulic system, delivery pipe and other parts with insulation materials to prevent the equipment from cracking due to freezing at low temperatures. Replace hydraulic oil, lubricating oil and fuel suitable for winter use to ensure that the equipment can start and run normally at low temperatures. Preheat the equipment before operation and wait for the hydraulic oil and lubricating oil to reach the normal working temperature before pumping.
During summer maintenance, pay attention to heatstroke prevention and cooling. Install air conditioners in the cab to provide a comfortable working environment for the driver. At the same time, dissipate heat from the hydraulic system to prevent the oil temperature from being too high. Regularly check the working condition of the cooling system to ensure that the radiator, fan and other components work normally. Repair in time if any cooling system failure is found. Avoid continuous operation for a long time in hot weather. Arrange rest time appropriately to allow the equipment to have enough time to dissipate heat.
In short, the maintenance of concrete pump trucks requires daily careful care and regular professional maintenance. Only by doing a good job in maintenance can the performance and safety of pump trucks be ensured and strong support be provided for construction.
