In the vehicle maintenance process, lubrication holds a vital position. The same holds true for the truck-mounted cranes within special vehicles. Today, the editor will present some knowledge regarding the lubrication of truck-mounted cranes to everyone.
First, let’s delve into the lubrication forms. The lubrication forms of truck-mounted cranes encompass two types: decentralized lubrication and centralized lubrication. Decentralized lubrication boasts the advantages of a straightforward structure, reliable lubrication, ease of maintenance, and low cost. Its drawbacks are: scattered lubrication points and a longer oil injection duration. Centralized lubrication can be further categorized into manual lubrication and motorized dry oil lubrication. During operation, it is imperative to adhere to the instructions step by step. For newly installed lubrication systems, tests must be conducted. Initially, disassemble the branch oil circuit connectors linked to each lubrication point until lubricating oil flows out from each connector. Before connecting to the lubrication point, verify that there is no dirt remaining within the pipe of the lubricating grease. Special attention should be directed towards the farthest point. There should be no leakage within the lubrication system.
Imagine a situation where the lubrication system has a leak, which not only leads to a waste of lubricating oil but also compromises the effectiveness of lubrication, increasing the wear and tear of components.
Secondly, it is the layout of the lubrication points. The distribution of the lubrication points of the truck-mounted crane is approximately as follows: both ends of the hook pulley shaft and the thrust bearings beneath the hook nut; both ends of the fixed pulley shaft; the steel wire rope; each reducer; each gear coupling; each bearing seat; the motor bearing; each hinge point on the brake; the piston part of the electromagnet of the long-stroke brake; the reverse idler wheel; the cable reel; the guide roller; the gears, screw rods and each hinge point on the rail clamp; the skew automatic adjustment device, and so on.
Understanding the precise location of these lubrication points is crucial for ensuring comprehensive and effective lubrication, thereby minimizing friction and wear.
Finally, the precautions for the lubrication of the truck-mounted crane should also be emphasized: The lubrication materials must be maintained clean, and different brands and grades of lubricating grease must not be mixed. It is necessary to frequently inspect the sealing condition of the lubrication system and add lubricating grease at regular intervals. Ensure that the lubricating oil circuit is not squeezed or collided. When it is necessary to dismantle the pipeline, the pipe ends and connections must be safeguarded to avoid damage or contamination. When reinstalling, the dirt at the connections must be meticulously removed to guarantee the cleanliness of the oil circuit. Where there is no lubricating grease injected at each connection mechanism, thin oil pots should be utilized to drip at each rotating gap on a regular basis to reduce the wear of the components and prevent rust.
The lubrication of the truck-mounted crane transport vehicle must be executed accurately. Only in this manner can the service life of the truck-mounted crane be effectively prolonged.
Now, let’s explore some additional aspects and considerations related to the lubrication of truck-mounted cranes:
The selection of the appropriate type and grade of lubricant is of paramount importance. Different components and operating conditions of the crane may require specific viscosities and additive packages in the lubricant to ensure optimal performance. For example, high-temperature or heavy-load components might need lubricants with enhanced heat resistance and anti-wear properties.
The frequency of lubrication also depends on various factors such as the operating environment, usage intensity, and the specific design of the crane. In dusty or corrosive environments, more frequent lubrication might be necessary to prevent contaminants from entering and damaging the lubrication film.
Regular monitoring of the lubricant’s condition is essential. This can involve checking for signs of contamination, oxidation, or degradation. Changes in the color, smell, or consistency of the lubricant can indicate a problem and prompt the need for replacement or additional maintenance.
In addition to the standard lubrication points, some hidden or less accessible areas of the crane might be prone to lubrication neglect. Special attention should be given to these areas during maintenance intervals to ensure complete coverage.
When replacing lubricants, thorough cleaning of the components and the lubrication system is necessary to remove any residue or contaminants that could affect the performance of the new lubricant.
It’s also beneficial to establish a lubrication schedule and log to keep track of when and which parts have been lubricated. This helps ensure that no areas are missed and provides a historical record for troubleshooting and maintenance planning.
Finally, training maintenance personnel on proper lubrication techniques and the importance of following correct procedures can significantly improve the effectiveness of the lubrication process and contribute to the overall reliability and longevity of the truck-mounted crane.
In conclusion, a comprehensive understanding and meticulous implementation of lubrication practices for truck-mounted cranes are essential for minimizing wear, preventing failures, and maximizing the operational lifespan and performance of these critical pieces of equipment.
