Before each use, conduct a comprehensive appearance inspection of the concrete pump truck. Check for any obvious damage or deformation on the body, especially critical parts such as hydraulic cylinders, boom, and outriggers. Damage to these areas can lead to unstable operation of the equipment and even safety accidents. Also, check whether the connecting bolts of various components are loose, and tighten them promptly if they are.

The hydraulic system is one of the core components of a concrete pump truck. Before each use, check the oil level and quality of the hydraulic fluid. The hydraulic fluid should be kept clean, free of impurities and water. If the hydraulic fluid becomes cloudy or has an odd smell, replace it immediately. Also, check for any leakage in the hydraulic system, including hydraulic cylinders, hydraulic lines, and joints. Any leakage can lead to insufficient hydraulic system pressure, affecting the normal operation of the equipment.

The electrical system is equally important. Check for any damage or aging of the electrical wiring, and whether the connections are loose. Pay special attention to the connections of key components such as the control panel and sensors. Regularly clean electrical equipment to prevent the accumulation of dust and dirt, which can affect the normal operation of the electrical system.

Regularly replace the hydraulic oil filter and air filter. The hydraulic oil filter should generally be replaced every 500 hours of operation, and the air filter should be replaced periodically according to the cleanliness of the working environment. Clogged filters can lead to decreased performance of the hydraulic system and engine, increasing the risk of equipment failure.

Regularly lubricate all moving parts of the concrete pump truck, including the boom, outriggers, and hydraulic cylinders. Lubrication can reduce friction between components, reduce wear, and extend the service life of the equipment. It is generally recommended to perform a comprehensive lubrication every 100 hours of operation.

Tires are an important part of the concrete pump truck, and their condition directly affects the stability and safety of the equipment. Regularly check the tire pressure and wear. Ensure that the tire pressure meets the standard. If the tires are severely worn or have cracks, replace them promptly.

Hydraulic system failure is one of the common problems of concrete pump trucks. If you find that the hydraulic system has insufficient pressure or slow action, there may be a problem with the hydraulic pump or hydraulic valve. Check the speed and pressure of the hydraulic pump in time, and replace the damaged parts if necessary. Also, check the sealing of the hydraulic valve, and clean or replace the damaged seals.

Engine failure can lead to the equipment not starting or operating normally. If the engine is difficult to start, there may be a problem with the fuel system or electrical system. Check whether the fuel filter is clogged and whether there is any leakage in the fuel lines. Also, check the battery's power and connections, and replace the battery if necessary.

The boom is a key component of the concrete pump truck, and its failure can lead to construction interruptions. If you find that the boom is not flexible or makes strange noises, there may be a problem with the hydraulic cylinder or joint of the boom. Check the sealing of the hydraulic cylinder in time, clean or replace the damaged seals. Also, check the lubrication of the joint parts to ensure good lubrication.

The maintenance and repair of concrete pump trucks are key to ensuring efficient operation of the equipment. By conducting daily appearance inspections, maintaining the hydraulic and electrical systems, and regularly replacing filters, lubricating, and checking tires, the service life of the equipment can be effectively extended and construction efficiency can be improved. At the same time, timely handling of common faults in the hydraulic system, engine, and boom can avoid long-term equipment downtime and ensure the smooth progress of the project. It is hoped that the introduction in this article will help you better manage and maintain concrete pump trucks, ensuring that the equipment is always in optimal operating condition.
