1. According to the characteristics of the terrain and the requirements of the operation project, correctly and flexibly use different methods of earth-moving to improve the working efficiency of earth-moving operations.
2. When operating the dispenser handle during work, it shall be correct and agile, so as not to block the oil passage of the slide valve, increase the oil pressure abnormally, and force the safety valve to open, so that the mechanical parts are in a relatively high pressure state. At the same time, the dispenser handle should automatically return to the “neutral†position during the operation of raising and lowering the bulldozer, and it must not be forcibly returned to the position. If the handle does not return to the “neutral†position, the oil pressure will exceed the opening pressure of the safety valve, allowing the oil to drain, and a “click†sound can be heard near the dispenser. At this time, the dispenser handle can be forced to return to the "neutral" position. Then check the cause of the malfunction, otherwise it will damage the hydraulic components.
3. When the parking or hydraulic system is not working and during the idle stroke of the blade, the dispenser handle should be placed in the “neutral†position to prevent the spring from being compressed and causing early fatigue damage.
4. When the bulldozer is in the transportation process (such as the transfer of work site), attention should be paid to raising the bulldozer to the transport height and fixing it with a safety bolt so that the blade is hung on the front bracket of the tractor to reduce the load of the hydraulic hose and the hydraulic cylinder. .
5, bulldozers in the land turning, over the ditch, should be low speed throttle, to avoid the hydraulic hose due to withstand greater impact and rupture.
Industrial Laser Distance Sensor
Industrial Laser Distance Sensor, we also call it secondary development laser distance module, which support TTL level and CMOS. The laser range sensor can be widely used in professional surveying, mapping, construction, robots, hunting arrows, industrial monitoring and automated measurement applications in electricity, transportation, etc. Our laser distance module supports data communication with RS232, USB with a simple adapter. The results of laser distance sensor can be evaluated with Arduino. We are always looking ahead, hoping we can make every measurement simple in life!
