Thread Content

In daily use, bridge cranes operate for very long periods of time. To extend the service life of bridge cranes and improve their work efficiency ； It is essential to carry out proper maintenance. So, what aspects need to be taken into consideration when lubricating a bridge crane? 1: It is necessary to ensure the purity of the lubricant itself, with no other substances added. II: It is prohibited to mix lubricants of different models and brands together. III: When lubricating a bridge crane, it is essential to do so at the prescribed intervals, and it is also necessary to choose the appropriate type of grease. IV: Under normal circumstances, it is best to use the pressure greasing method to add grease. The advantage of this method is that it allows all the grease to flow onto the friction surfaces. 5: If the operating environment of the bridge crane is relatively humid, it is best not to use sodium-based grease, as this type of grease has a strong hydrophilic property and tends to lose its effectiveness easily. 6: When there are no oil spots in other areas, it is best to use a thin oil bottle for rotation, in order to prevent unnecessary friction and rusting of the machinery.
