In the field of heavy industrial lifting, type slewing bearing fixed crane has shown excellent performance, especially in carrying large heavy objects.
First of all, the design structure of its core component, the slewing bearing, is extremely critical. The slewing bearing adopts inner and outer rings made of high-strength alloy steel and a specially designed arrangement of rolling elements (balls or rollers). This structure can evenly disperse the huge axial force, radial force and overturning moment generated by large heavy objects. For example, in large bridge construction projects, when lifting bridge components weighing tens of tons or even hundreds of tons, the raceways and rolling elements of the slewing bearing work closely together to smoothly transfer the gravity of the heavy objects to the base and supporting structure of the crane, effectively preventing structural damage caused by local stress concentration and ensuring the stability and safety of the overall structure of the crane.
Secondly, type slewing bearing fixed crane is usually equipped with a high-power lifting mechanism. This mechanism works in conjunction with the slewing bearing to generate sufficient lifting force to lift large heavy objects. The powerful motor drive system combined with the precision reducer can not only provide stable lifting power, but also achieve precise lifting speed control. During the lifting process, whether it is slowly lifting the heavy objects to the specified height or making fine adjustments when placing the heavy objects, accurate operations can be performed to avoid damage to the heavy objects and the crane itself due to unstable lifting speed or inaccurate control.
Furthermore, the chassis and tower structure of the crane have been specially strengthened. In order to meet the load-bearing requirements of large heavy objects, the chassis adopts a heavy steel beam structure with extremely high rigidity and torsion resistance, which can firmly support the slewing bearing and the upper structure of the entire crane. The tower part enhances the vertical load-bearing capacity and wind resistance through the optimized cross-sectional shape and the use of high-strength materials. When lifting containers at the port, even in the face of the sea breeze and the heavy pressure of large container stacks, the crane can still maintain a stable posture and complete the lifting operation safely and reliably.
In addition, the type slewing bearing fixed crane also provides solid protection for carrying large heavy objects in terms of safety protection system. It is equipped with an advanced overload protection device. Once the lifting weight exceeds the rated value, the system will immediately start, stop the lifting action and sound an alarm to prevent serious accidents such as crane collapse caused by overload. At the same time, it also has an anti-sway control system. When lifting large heavy objects, the system can effectively reduce the swing amplitude of the heavy objects and further improve the safety and accuracy of the operation.
In summary, the type slewing bearing fixed crane has an incomparable unique advantage in carrying large heavy objects with its advanced slewing bearing structure, powerful lifting mechanism, reinforced chassis and tower body, and perfect safety protection system, and has become a powerful assistant in many large-scale engineering and industrial lifting scenarios.
