How to Prevent the Bearings of Single Beam Crane from Rust？

At present, single-girder cranes are widely used on construction sites of large-scale projects, which can help the effective progress of the project.

The bearings are a very important part, but if you do not pay attention to maintenance and correct use methods, it is easy to cause rust and affect normal use.

As the professional cranes manufacturer&supplier in China, DQCRANES will be very pleased to tell you how to prevent rust on the bearings of single-girder cranes:

Surface cleaning For the cleaning of bearings, the most suitable method must be selected according to the nature of the material and the environmental conditions.

• Common cleaning methods include chemical treatment cleaning method, mechanical cleaning method and solvent cleaning method.
• And it should be noted that the surface needs to be dried after cleaning. You can use filtered dry compressed air to dry it, or use a dryer to dry it.
• In addition, under simple conditions, the bearing can also be wiped dry with a cotton cloth.

Use anti-rust oil to apply appropriate anti-rust oil (isolating air) on a clean basis, and for the application of anti-rust oil, choose the most suitable painting method according to the use and size of the single-girder crane.

• The method of applying anti-rust oil is as follows: 1. Soaking method: For relatively small-sized ones, it can be soaked in anti-rust grease to make the grease adhere to the bearing surface and play a protective role. And the thickness of the oil film can be adjusted according to the actual situation. The temperature and viscosity are adjusted;
• 2. Spray method: For large cranes, the spray method will be more suitable and convenient. It is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil. Rust oil, but complete fire protection and labor protection measures must be adopted for safety protection.

The above is our introduction to the two important aspects of single-beam crane bearing anti-rust. One is cleaning, and the other is to use appropriate methods to apply anti-rust oil to prevent the occurrence of rust more safely and effectively, so that it can play its role, Maximum function.
