What is the difference between a large-tonnage crawler crane and a small crawler structure?

Difference: The operation of large tonnage crawler crane products is different from that of small tonnage. Take Xugong's products of more than 300 tons as an example. Small tonnage adopts electro-hydraulic proportional control, which is simple to operate. Large-tonnage crawler crane adopts electrical proportional control, and its main components are all imported from Germany, so its internal electrical system is complicated. In addition, it is impossible for crawler crane drivers to learn to use it now. It is recommended that drivers who have few years of experience in operating large-tonnage cranes should not operate directly. Being responsible for yourself is also responsible for the company.
