1. Girder structure
Single girder and double girder are different; Different main beam structure, bearing capacity is different, if it is often lifting 5 tons, appropriate to buy some larger, to avoid a certain overload, unable to complete the work, more embarrassing. Economic conditions are good, the budget is adequate, as far as possible to choose a bit more weight, this is a wise choice.
2. Girder span problem
According to the different use site of gantry crane, what needs to be considered is whether it is convenient to pass the car below, to avoid occupying the place, resulting in other inconvenience, is also very annoying, after installation, can not be changed.
3. Whether there is a cab
Before installation, you need to consider the number of driving, if often used, for the sake of safety, it is best to have a cab, so that the personnel can stand in the cab to watch the following work site, a wide field of vision to increase safety, not easy to lift, meet other personnel.
4. Whether frequency conversion structure should be installed
Frequency conversion is more power saving, safer operation, driving is easier, but the cost is high, if the small and medium-sized enterprises, you can not consider, in order to save costs.
5. Lifting is mainly car and electric hoist
The lifting structure of each gantry crane is very important. If there is no good lifting or operation, the operation speed will be slow and the carrying capacity will be weak.
6. Consider the job level
For cranes with large tonnage, try to choose higher ones, such as A6, and smaller ones. If the carrying capacity is low, try to choose A3.
