gantry crane corrosion prevention work is very important. Gantry crane corrosion can be divided into two situations: chemical corrosion of high temperature drying damp working environment and electrochemical corrosion of humid environment, therefore, to achieve the purpose of gantry crane anti-corrosion needs to rule out the influence of corrosive media.

For Gantry Crane itself, to paint isolation layer with anti-corrosion effect as one coated for gantry crane, to ensure the sealing of the various parts be effective, to clear the moisture, rust and other pollutants on the crane timely, to improve the working level of the crane, etc. It has great significance for corrosion resistance of gantry crane. In the working environment of crane, it is feasible to avoid the work in the acidic environment and wet environment, and to improve the humidity and cleanliness in the working environment as far as possible. It is also important to note that if it is a working environment that is prone to mechanical corrosion, it is necessary to select a dedicated crane at the corresponding level of work.
In addition to doing good anti-corrosion work, carrying out the necessary maintenance work, it is also very important to do the maintenance of the gantry crane. Ensure the oil, water and air with adequate supply, if the energy supply is insufficient, this will cause the crane to be difficult to start, poor lubrication, power loss, serious wear and tear, and cannot operate normally and shorten the service life. For these crane parts that are very easy to have problems, we should do a good job of daily safety inspection. Due to lifting equipment in use process that will be affected by different levels strength of vibration impact, fastening parts of the bolt and nut can appear loose phenomenon, so we should always check to prevent loosening and damage to the body failure.
Gantry crane buffer
The buffer is an important part for gantry crane and its function is: when limiter or brake of gantry crane have problems, it can absorb gantry crane travelling function, that is to absorb the gantry crane’s operational function to cushion the impact for preventing collision with other objects which is due to its inertia of gantry crane. The crane buffer of the gantry crane is to be placed in two places, one is to stop the gantry crane and the retaining body displacement, and the other is the gantry crane who have the same rail.
The crane buffer of the gantry crane is divided into three types:
• One is the physical buffer. The physical buffer is divided into rubber buffer and polyurethane buffer. The structure of the rubber buffer is simple and can play a blocking role, while the polyurethane buffer can absorb more energy and has corrosion resistance, anti-high temperature and anti-low temperature. Polyurethane buffer can Insulation and also be explosion-proof, at the same time its price is low, the service life is long, installation and maintenance is also very convenient, so polyurethane buffers are currently widely used in the international community.
• One is the spring buffer. The structure of the spring damper is very simple. Crane spring buffer are three parts which is the bumper, the spring and the shell. The principle of its main work is to prevent the accident from occurring when the gantry crane collides with the spring buffer and converts the energy into the compression energy of the spring.
• The third kind is the hydraulic buffer. The working principle of this buffer is that in the event of a gantry crane crash, the hydraulic buffer can let the various parts of the gantry crane pass through a process that consumes a large amount of kinetic energy and thus acts as a buffer.
