Application of Tilt Sensors in Construction Machinery
--- Changsha Pingchuan Electronic Technology Co., Ltd.
In various types of construction machinery operations, our greatest concern is when the center of gravity suddenly changes, causing the machinery to tip over under load. Therefore, foreseeing these dangers to avoid many major accidents and achieving automatic control of mechanical equipment require measuring the attitude of the vehicle body and its actuators, which necessitates a safety system.
The transition of mechanical equipment from traditional mechanical-hydraulic systems to electro-hydraulic systems, especially the widespread application of sensors, has provided an excellent technical platform for the upgrading of construction machinery and the improvement of work efficiency, such as in cranes, pump trucks, mortar trucks, graders, pavers, excavators, rotary drilling rigs, elevators, aerial work platforms, etc. Through different sensors installed in specific locations, a complex system is formed to monitor various data of the mechanical equipment and continuously transmit this data. When the machinery approaches preset dangerous thresholds, it alerts the operator, and some equipment can even automatically cut off power to prevent critical situations.
Of course, the performance of the sensors is crucial to the accuracy of the entire system. For example, if there is a ±2° error in measuring the lifting angle of a crane's boom, the system must account for this error to avoid compromising safety.
For instance, measuring the verticality of the mast of a rotary drilling rig and adjusting the attitude of the entire machinery to achieve a level state before operation;
For instance, controlling the lifting angle of a crane's boom and the digging depth of an excavator both require angle measurement and control.
For instance, tilt sensors are used in telescopic booms and aerial work platforms for safety systems.
For instance, in mining, crawler drills use tilt sensors to monitor and control the drill bit angle.
The construction machinery industry has various measurement requirements. In summary, tilt sensors in this industry are used to enhance the safety of lifting equipment, and their applications are endless.
