As we all know,undercarriage is the key part of crawler crane.To ensure stable and smooth operation under various complex conditions,undercarriage parts need to withstand heavy pressure.In this case,failing to perform daily inspection or ignore the crawler crane undercarriage maintenance can lead to significant economic losses.How should we carry out daily inspection and crawler crane undercarriage maintenance?
5 Key Parts of Crawler Crane Undercarriage and Features
Crawler crane undercarriage is mainly composed of crane track plates,crane track rollers,crane top rollers,crane idlers and sprockets.
| Part name | Main function and features |
| Track plate | Distribute the machine’s overall weight on the ground.One side rub against the road ,the other side needs to rub against with other undercarriage parts. |
| Track roller | Support the overall machine weight.This will result in heavy wear,so it requires an excellent wear-resistance. |
| Top roller | Adjust the track tension and prevent excessive track sagging. |
| Idler | Guide and correct the track direction,prevent track deviation. |
| Sprocket | Transmit power and drive the track operation. |
How to Carry Out Daily Inspection and Crawler Crane Undercarriage Maintenance?
1 Clean the crawler crane undercarriage parts before or after each use.
Because the crane operating environments are usually in construction sites or mines with harsh working conditions. Gravel or debris that gets into the undercarriage during operation can cause extra wear and tear on undercarriage parts. Regularly cleaning the debris in the crane undercarriage before or after each use can effectively reduce the friction between the various parts of the undercarriage. Effectively extending the service life of the crane. This is the most common operation in the crawler crane undercarriage maintenance.
2 Regular inspecting the crawler crane undercarriage parts excessive wear, crack or deformation
Working continuously under heavy load may cause the crawler crane undercarriage parts to wear,crack or become deformed.Regular inspecting these problems and fix the problems parts timely can reduce the downtime of cranes. If wear, cracking or deformation is severe, it is necessary to replace the corresponding parts timely.
3 Scheduled check the lubrication condition of crawler crane undercarriage parts
Lubrication is an important step of crawler crane undercarriage maintenance.Regularly check whether the lubrication of crane undercarriage parts (especially track wheels) is sufficient.Is there any oil leakage in the oil seal system of crane track wheels. Replenish lubrication for the wheel body in a timely manner. And pay attention to choose the manufacturer’s recommend regular lubrication.
4 Scheduled check the tension of track
Pay close attention to whether the tension of the track is appropriate and adjust it timely. Prevent safety issues caused by track loose or slipping tracks during crawler crane operation.The track tension adjustment can be made according to the working condition of crane. After the adjustment finished,the crane can be operated again to observe whether the tension of tracks is appropriate.
Precautions for crawler crane undercarriage maintenance during operation
In addition to daily inspection and maintenance, some precautions during the operation of the crawler crane are also very important for the crawler crane undercarriage maintenance.Good usage habits can effectively extend the service life of crawler crane undercarriage parts . Here are a few aspects to pay attention to during the daily use of a crawler crane.
1 Pay attention to the working conditions of the road surface
Before operating the crawler crane, pay attention to clearing the gravel and obstacles on the road surface. Try to avoid deep pits, steep slopes, and uneven hard roads as much as possible.Avoid prolonged travel on uneven or continuously sloped ground. Such operation may lead to accelerated, uneven wear on idlers and support rollers, and increase the risk of track deviation.
2 Maintaining correct walk habits
Do not take a sudden turn at high speeds or make sharp turns in place. Long-distance traveling shall be kept at a low and constant speed, with no frequent start-stop or sudden acceleration and braking.Avoid long-distance travel under no load. The crane undercarriage is designed for load-bearing operation and not intended for long-distance transit.
3 Pay attention to the load capacity of the crawler crane
Clearly define the maximum load range of the crawler crane. Try to avoid weight overload as much as possible. When carrying heavy objects, do not rotate significantly or pull diagonally or forcefully. These may cause the crane undercarriage to bear additional lateral torque.
The above are all the key suggestions about the crawler crane undercarriage maintenance. We hope it can help your crane achieve a longer service life.
