Working principle of tire crane

Go to Sina blog, the favorite pupil of weightlifting expert Tian Zi. My blog is dedicated to spreading lifting safety and professional technical knowledge.

Tire crane is a kind of full slewing crane, and its lifting mechanism is installed on a special chassis composed of weighted tires and axles. Its superstructure is basically the same as that of crawler crane. In order to ensure the stability of the fuselage during installation, the crane is equipped with four telescopic legs. On the flat ground, you can carry out small lifting weight and low-speed operation of lifting objects without legs. Generally, it is necessary to put down the legs, increase the bearing surface and level the fuselage to ensure the stability of the crane.

Summary: the application scope of tire crane is relatively small, and the tonnage is small in terms of lifting capacity. Its traveling speed is generally lower than that of truck crane, so it can be lifted without legs (note: yes or no, depending on the lifting load and environment. In order to enhance stability or lifting capacity, legs are generally needed), and driving can be limited on flat roads.
