Truck crane is easily abraded during working, which will cause damages to the crane and even result in stopping working. Therefore, good lubrication is very important to keep the crane working smoothly. Generally, the parts and attachments should be checked every 2-3 months to make sure the lubricant is working, and the checking period depends on the machine’s working frequency and the ambient environment.
Different lubricants should be used for different parts, which will yield twice the result with half the effort. The parts that need to be lubricated include truck crane decelerator, wire rope, bolts, bearings, gears and impeller of hydraulic brake. There are some matters that need attention when lubricating. The lubricant in different models and brands should not be mixed, the lubricant should be kept clean, the pipeline should be washed frequently, the lubricant amount for the decelerator should not exceed the limit, otherwise, oil leak will happen.
There are some standards to examine good lubricant. The lubricant in high quality would not deteriorate in wet days and will form a layer of protective film to keep water and moisture away from the metal surface. Good lubricant would not be affected by temperature or cause chemical reaction with acid and soda. And lubricant in high quality has strong oxidation resistance to resist erosion of the salt. So much more attentions should be paid to choose the right lubricant for your truck crane, which will not only reduce downtime but also extend machine’s service life.
