The safe operation of truck cranes is very important to the construction. Some vibrations, driver misoperation and insufficient rigidity caused by corrosion of some original parts may greatly reduce the safety performance of truck cranes. Therefore, the use of sensor technology for truck cranes Monitoring is particularly necessary.
First, we need to collect signals from various "sensitive parts" of the truck crane. The overturning moment and the rigidity of the boom are important safety parameters of the truck crane. Monitoring them with sensor technology is the key to ensuring the smooth operation of the truck crane. Therefore, we need to install sensors in these sensitive parts of the truck crane to pass the detected signals to the on-board computer.
Length, angle sensors and pressure sensors can be used to measure the lifting moment. They can monitor the length and angle of the boom and the pressure of the hydraulic cylinder in real time to measure the load capacity of the crane and play a role in limiting the load. The load sensor can measure the steady state of the crane. When the truck crane is about to become unbalanced, the load on its two adjacent legs will become smaller. When it is small to a certain degree, the computer will "think" that the crane will be unbalanced and report the alarm Personnel to achieve the purpose of monitoring stability. The acceleration sensor mainly measures the vibration of the boom. It cooperates with the length and angle sensors to reflect the deflection and rigidity of the boom. Even if the crane is not overloaded, due to the influence of other factors, the boom vibration is strong, so that the inertia of the object being lifted is very large, the crane is also easy to lose stability, and even the rigidity of the boom will be poor, so The measurement of vibration cannot be ignored either.
Folder is specially used to hold the whole page of documents, the main purpose is to better save files, make it neat and regular.Folders are tools for storing, protecting and managing paper documents.Materials include PP, PVC, cardboard;There are parts of imitation leather, cloth and so on.There are many kinds of folder categories: including single strong folder, double strong folder, information booklet, two inch folder, three inch folder, different specifications of double open folder, single folder (also known as l-type folder), multi-page folder.
