Crane Maintenance - Abundant: Sufficient oil, water, and air supply

Delays or interruptions in diesel, gasoline, or air supply can lead to difficulties in starting, poor combustion, decreased power, and cranes' engines failing to operate normally. Insufficient or interrupted oil supply can result in poor engine lubrication, severe wear on the machinery, and even the risk of seized bearings. Inadequate coolant can cause excessive engine temperatures, reduced power, increased wear, and shortened lifespan.

2. Crane Maintenance - Inspection: Regularly check for tightness

Due to the vibrations and impact during the operation of diesel and gasoline engines, bolts and nuts are prone to loosen. Additionally, all adjustment bolts in various parts should be inspected to prevent accidents caused by loosening that may damage the engine body.

3. Crane Maintenance - Clean: Oil clean, water clean, air clean, and body clean

Diesel and gasoline are the primary fuels for crane engines. Impurities in these fuels can lead to wear on the mating parts, increasing clearances and causing oil leaks, drips, and reduced fuel supply pressure. This can result in severe issues like blocked oil passages and bearing burns. Excessive dust in the air accelerates the wear of cylinder liners, pistons, and piston rings. Impure cooling water can cause scale buildup in the cooling system, hindering the engine's heat dissipation and reducing lubrication conditions, leading to significant wear on the engine body. Un洁净 surfaces can lead to corrosion, shortening the lifespan of the engine.

4. Crane Maintenance - Use: Proper operation of the crane engine

Prior to operation, ensure that all lubricated parts, such as axle bushes, are properly lubricated. Wait until the engine temperature reaches 40℃-50℃ before commencing work. Strictly avoid long-term overloading or low-speed operation. Before shutting down, first remove the load and reduce the engine speed. In winter, after parking, wait until the engine temperature drops to 40℃-50℃ before draining the coolant (except for engines already filled with antifreeze). Regularly maintain the engine to keep the crane engine running in optimal condition. Be vigilant and conduct frequent checks; promptly address any issues that arise.

5. Crane Maintenance - Wear: i.e.,磨合

This is the foundation for extending the service life; whether it's a new engine or one that has undergone major repairs, it must be broken in according to protocol before it can be put into normal operation.

6. Crane Maintenance – Adjustment

Valves clearance, timing, fuel injection advance, injection pressure, and ignition timing for both diesel and gasoline engines should be regularly inspected and adjusted to ensure the crane engine remains in optimal technical condition, thereby saving fuel and extending its lifespan.
