It also can be equipped with many lifting devices for special work.


Prohibited for lifting high-temperature solution, flammable, explosive, corrosion, overloading, dust and other dangerous operations.



Product superiority


1. First of all, the lifting structure relies on the completion of the track, which eliminates the traditional fault source from the big wheel or diesel generator set, and reduces the fault incidence during the operation of the crane.

2. Secondly, the gantry crane is driven by electric power, so there is no need to change the oil during operation, and the maintenance consumables are effectively controlled.


The maintenance expenses are small, low cost, and the economic benefits are significant.

3. Thirdly, in the process of rail lifting, the track is in a fixed state, and it is coordinated with the positioning device of the cart to avoid deviation in the case of high load force, with high level of automation.

4. Finally, in the operation process of the gantry crane, it is directly connected with the high-voltage power supply.


When the mechanism does not operate, there is basically no noise pollution or air pollution.


Moreover, the energy feedback device can be introduced to achieve energy feedback under the descending state of the lifting mechanism, so as to achieve the purpose of saving energy consumption.
