Details of the selection of the gantry crane

The number of road and railway construction project in China is constantly increasing, this is due to the improvement of our country's economy, promoting the improvement of the people's income, and therefore are also constantly improve the quality of life.

In order to improve the convenience of people's travel, China has put a lot of effort into construction projects such as roads.

For the construction project, due to the bad nature of the construction environment, we usually use lifting machinery to carry out the high-altitude work, such as the gantry crane, the bridge machine and other forms.

According to the professional people's theory, the nature of the gantry crane is the gantry crane, and the gantry crane is actually a form of deformation of the bridge crane.

Due to different construction environment, we need to use the type of gantry crane is not the same, so we before the start of the project construction, must according to the construction environment, choose a the most suitable kind of gantry crane.

In the process of choosing the portal crane, we must first meet the relevant regulations of general gate crane.

In general, the weight is under 50t and the span is within 35m, without special use requirement, the single main beam type should be selected.

If the width of the door is wide, the work speed is high, or the heavy lifting is often used, the two-beam door crane should be selected.

For gantry crane at the same time, its span is also a important factor affecting the quality of the crane itself, so we in the process of selecting the gantry crane, in meet the equipment using the span series standard terms and conditions of the premise, should try to reduce the span.

In addition, in the actual work of the gantry crane, there should be a certain space dimension between the external dimensions and the freight and transportation vehicles of the stacking field, so as to facilitate the loading and unloading operation.
