The invention provides a rotary crane arm of a fixed slewing bearing type crane, and relates to the field of crane arm equipment. The rotary crane arm comprises a base. A rotation device is fixedly arranged on the top of the base. A crane arm is arranged on the top of the rotation device. The top of the crane arm is movably connected to a crane jib through a middle shaft. A supportive bearing pedestal is fixedly arranged on the bottom of the inner wall of the rotation device. A supportive shaft sleeves on the top of the supportive bearing pedestal. A box is inserted into the outer surface of the supportive shaft. The outer surface of the supportive shaft is fixedly connected to the box. The rotary crane arm has the advantages that a first motor drives a driving wheel to rotate, the drivingwheel drives a driven wheel to rotate, through the cooperation of a first gear and a second gear, the crane arm is rotated, the application range of a crane is enlarged, the work efficiency is improved, and convenience is generated for people.
Description
technical field [0001] The invention relates to the technical field of boom equipment, in particular to a rotating boom of a fixed slewing bearing crane. Background technique [0002] Cranes refer to multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range. With the continuous development of various engineering constructions, the requirements for various engineering equipment are getting higher and higher, and cranes are becoming more and more diverse. , Fixed slewing bearing crane is also one of the very important cranes. [0003] The fixed slewing bearing crane is an indispensable equipment. At present, the general cranes on the market are composed of a base, a boom, a balance device, a boom and a hook. The boom and the base are fixedly connected, which makes the crane The range is very limited during use, which makes the crane have limitations in work and brings a lot of inconvenience to people.
