Maintenance for Crawler Crane Undercarriage Parts
The crawler crane undercarriage parts can stably support the weight of the entire crawler cranes, ensuring the stable operation under various complex working conditions. It is very important to evaluate the crawler crane undercarriage parts regularly. In this way, you can change or deal with damaged, missing, irregular or excessively worn parts at an early stage. There will be no need to stop the crawler crane frequently. If the crawler crane is often used in harsh conditions, the crane undercarriage parts need to be checked more frequently.
To keep the crawler crane undercarriage in good condition, you need to guarantee to maintain the crawler crane undercarriage parts promptly. Regular inspection and replacement of worn crawler crane undercarriage parts is necessary preventive maintenance.
Key Components of Crawler Crane Undercarriage
Track Shoe
The track shoe is used to support the whole weight of crawler cranes and provide stable walking ability in various terrains and harsh working conditions.
Track Roller
Track rollers are screwed under the crane frame to support the weight of the crawler crane and distribute it on the track shoes, then help the tracks move along the rollers.
Top Roller
The function of the top roller is to support the tracks so that the tracks has a certain degree of tension.
Idler
Guide the track to wind correctly and adjust the tensioner assembly to ensure the track has the proper tension.
Sprocket
The drive tumbler plays the role of driving the crawler tracks. It is fixed on the travel motor and transmits the driving force of the travel motor to the crawler tracks through the gear structure.
Track chains
The track chains are used to transmit the power from the engine to the crawler tracks and then help the crane move forward or backward.
How to ensure the crawler crane keep prefect performance?
The correct maintenance is quite necessary.
- Timely cleaning of the crawler crane’s undercarriage parts can reduce the wear and resistance of dirt and dust on the crane track shoes and crane rollers. Cleaning the crawler crane’s undercarriage daily will help extend the service life of the track shoes and crane rollers.
- Regularly inspect the track shoes for cracks or out of shape and repair them timely. If they are excessively worn, they need to be replaced. The worn track shoes are more likely to break during the operation of the crawler crane, resulting in more serious losses.
- Regularly replace the entire track shoe assembly to achieve even weight distribution. If only replacement broken ones are used, it may lead to uneven weight distribution of the crawler cranes and accelerated undercarriage wear.
- Check the wear of the rollers regularly, not only the track roller and top roller but also the idler and sprocket. If the wear exceeds the normal standard, replace them in time. It is better to replace the rollers on the same side one time. If you only replace some of them, the new crane rollers will be more likely to wear out due to uneven force.
- Arrange regular lubrication of the chains and crane rollers, like track rollers, toprollers idler, etc. It can reduce the friction between the roller surface and other parts and extend the service life of these crane
- Ensure that the bolts for the track shoes, track roller, top roller, idler, and sprocket are properly tightened, as loose bolts can easily lead to broken crawler crane undercarriage parts.
- Check the roller shafts and seals regularly. If they are badly worn or leaking, replace new rollers in time.
- Track chains will be stretched due to the using day by day and need to be adjusted or replaced in time.
Essential Practices for Crawler Crane Operators
Know and Adhere to Maximum Load Capacity
Operators must know the maximum load capacity of crawler cranes and follow this requirement strictly during operation. Overload operation will not be allowed. This can avoid damage to the crane undercarriage due to excessive load.
Avoid Uneven Stress and Obstacles
Avoid crushing stones or being stressed on one side for a long time when driving. When the crawler crane undercarriage is tilted, the power will act on the crawler crane undercarriage parts, and the impact will easily cause cracks or even breakage of the crawler crane parts.
