Excellent electronic control system

1. The boom has undergone 800000 times of anti fatigue tests. Each weld has undergone non-destructive testing. Two one-way balance valves are used to ensure the construction safety of the boom. The Z-shaped structure of the boom is designed to reduce the extension space, make the boom support safer, and reduce the jitter during operation.
2. It can work at full load for a long time, and the main components will not be damaged, overloaded or overheated after 24 hours of continuous work.
3. The quality of structural parts is good, and the boom, machine body, outrigger and turntable will not be broken, cracked or deformed within one year.
4. Pumping mechanism: 200X1400 delivery cylinder, outlet pressure: 13MPa, better suction performance, long pumping distance and high efficiency.
5. The motion controller (microcomputer) replaces the traditional PLC control mode, and the system runs stably with lower failure rate.
6. Double accumulators are adopted for more powerful pumping and more stable system operation.
7. The external design of turret conveying pipe improves the efficiency of repair and maintenance by 50% - 70%; Integral shaft sleeve, high structural strength, high reliability, simple assembly and disassembly;
8. Modular design of electrical system hardware, few components and high reliability
9. With the fuel consumption automatic matching power mode, the engine always works in the economic fuel consumption area, saving 25% of fuel
10. The machine has sufficient power and is suitable for driving on complex and muddy roads.
