What are the main characteristics of gantry cranes

1. Main beam structure

Single girder and double girder is the difference;Different girder structure, bearing capacity is different, if it is often lifting 5 tons, it is appropriate to buy some larger, to avoid a overload, unable to complete the operation, it is more embarrassing.Economic condition is good, budget is sufficient, choose a bit bigger to lift weight as far as possible, this is wise choice.

2. Main beam span problem

According to the use of different gantry crane site, need to consider is the following car is convenient, to avoid occupying the place, resulting in other inconvenient, is also very headache, after installation, can not be changed.

3. Whether there is a cab

Before installation, you need to consider the number of times of driving. If you often use it, it is better to have a cab for safety, so that the personnel can stand in the cab and watch the operation site below. The wide field of vision increases the safety, and it is not easy to meet other personnel after lifting.

4. Whether the frequency conversion structure needs to be installed

Frequency conversion is more power-saving, safer to operate, and easier to drive. However, it costs more. If small and medium-sized enterprises, it can be ignored to save costs.

5. Lifting mainly includes trolley and electric hoist

The lifting structure of each gantry crane is very important. If there is no good lifting or running, the operation speed will be slow and the carrying capacity will be weak.

Consider the job level

For large tonnage cranes, try to choose a higher working level, such as A6 and small cranes. If the carrying capacity is low, try to choose A3 level.
