Backhoe loaders are complex machines that can get in various problems during operation.

In loader respect: The loader is used to lifting and carrying materials with the front bucket. If the loader is not working properly, it can cause less oil flow from the pump, broken pump, boom and bucket overload, issues with control linkage binding, auxiliary circuit on-over relief or twisted cylinder shafts.

In engine respect: The engine is the source of power for the backhoe loader. If the engine is not working properly, it is not easy to start, poor performance, excessive fuel consumption, smoking or noising. Some of the possible causes of engine issues are low oil level, dirty or contaminated oil, clogged air filter, faulty fuel system, worn or damaged belts, hoses, spark plugs, injectors or sensors, or incorrect settings.

In hydraulic system respect: The hydraulic system is responsible for powering the loader and backhoe functions, as well as the steering and brakes. If the hydraulic system is not working properly, it can cause low or no pressure, slow or jerky movements, leaks, overheating or noise. Some of the possible causes of hydraulic system issues are low fluid level, dirty or contaminated fluid, clogged filters, worn or damaged hoses, valves, pumps, cylinders or seals, or incorrect adjustments.

In backhoe respect: The backhoe is used to digging and moving materials with the rear bucket. If the backhoe is not working properly, it can cause low digging force, slow swing speed, excessive wear on pins and bushings, loose stabilizers or outriggers, or damaged teeth or cutting

In electrical system respect: The electrical system provides power to the lights, gauges, switches and other components of the backhoe loader. If the electrical system is not working properly, it can cause dim or flickering lights, dead battery, faulty gauges or indicators, or malfunctioning switches or solenoids. Some of the possible causes of electrical system issues are loose or corroded connections, blown fuses, damaged wires or harnesses, faulty alternator, starter or regulator, or low battery charge.

Mingyu Heavy Industry has three series of backhoe loaders: 388 series, 30-25 series and 370 series. The 388 series includes models such as 388, 388II, 388T, 388H. These models have different bucket capacities, rated power, rated loading and operating weights. They are designed to enhance productivity with high stability, low maintenance and versatility.
