Double Girder Gantry Crane is very important to ensure accuracy when lifting heavy objects. Here are some key ways to ensure its lifting accuracy.
First of all, high-quality manufacturing and installation processes are the basis. When manufacturing the main beam, end beam, running mechanism and other components of the crane, they must be processed and assembled in strict accordance with the design requirements and high-precision standards. Accurate geometric dimensions and good matching accuracy can reduce deviations and shakes during operation, providing the prerequisite for accurate lifting. For example, the straightness and horizontality deviations of the main beam should be controlled within a very small range, and the wheels of the running mechanism should be installed to ensure coaxiality and verticality.
Accurate control system is one of the key factors. Modern Double Girder Gantry Crane is usually equipped with an advanced electrical control system that can achieve precise adjustment and positioning of lifting and running speeds. By adopting high-performance inverters, encoders and other equipment, the motor speed can be accurately controlled, thereby achieving the purpose of accurate lifting.
Good lifting mechanism design and performance also play an important role in accuracy. The diameter of the hoisting drum, the winding method of the wire rope, and the structure of the hook will affect the lifting stability and positioning accuracy of the heavy object. The use of high-precision drums and reasonable wire rope winding methods can reduce jitter and deviation during the lifting process.
In addition, regular maintenance and calibration work is indispensable. Regular inspection and calibration of key components of the crane, such as travel switches, encoders, limiters, etc., to ensure that they can accurately feedback the position and operating status of the crane. At the same time, the parameters of the electrical control system are regularly optimized and adjusted to meet the accuracy requirements in actual work.
The skills and experience of the operator also have a direct impact on the lifting accuracy. Professionally trained operators can master the operating skills of the crane, reasonably control the speed, acceleration and braking according to the characteristics of the heavy object and the lifting requirements, and achieve smooth and accurate lifting operations.
During the lifting process, environmental factors also need to be considered. For example, avoid high-precision lifting operations under adverse environmental conditions such as strong winds and strong magnetic fields. For special lifting tasks, auxiliary positioning equipment, such as laser rangefinders and visual recognition systems, can also be used to further improve the accuracy of lifting.
In summary, to ensure the accuracy of Double Girder Gantry Crane when lifting heavy objects, it is necessary to take a series of effective measures from multiple aspects such as manufacturing and installation, control system, lifting mechanism, maintenance and calibration, personnel operation and environmental control.
