When the load exceeds the limit or the vehicle body tilts too much, the gasoline engine mini dumper does have a "life-saving skill" - it can automatically cut off the power. This function is like installing a "smart butler" on the car. Once a dangerous sign is found, the engine will be "turned off" immediately to prevent rollover or damage to parts. For example, when the driver loads sand and gravel to the "top" and the truck bed is about to be pressed up, the sensor on the car will detect the overweight like an "electronic scale", and then send a command to the engine through the computer chip to suddenly cut off the power. At this time, the car is like being stepped on the brakes. Although it will stop suddenly, it avoids axle breakage or tire blowout. For example, when the car is tilted into a "seesaw" when climbing a slope, the angle detector in the car will find something wrong and immediately cut off the power, so that the car stops halfway up the slope instead of continuing to rush up and causing rollover. However, the sensitivity of this "automatic power off" depends on the grade of the car model. Some low-end cars may only have a simple overweight alarm, which beeps but does not cut off the power, and it depends on the driver's own reaction to reduce the load. High-end models will be equipped with precision sensors and intelligent control systems, which can not only cut off the power, but also automatically open the anti-skid device, and even link the fire extinguishing system like a mining dump truck. Just like the current smart cars can automatically brake to avoid collisions, this kind of safety design is gradually popularizing small machinery.
It should be noted that this protection function should not be abused. If the driver always overloads the car to trigger the power off, the engine and transmission system will accumulate damage after a long time, just like a person's arm is always suddenly pulled and easily dislocated. Moreover, some older models may not have this function at all, relying purely on the driver's experience and judgment-at this time, you have to drive like an old truck without ABS, reserve a safety margin when loading, and check the angle before climbing.
In general, the "automatic power off" of modern mini dump trucks is a thoughtful design, but whether it is there or not, and whether it works, depends on the configuration of the car. When buying, you can focus on asking the seller whether it has "overload protection" or "tilt protection" functions, just like asking whether it is waterproof when buying a mobile phone. After all, safety is something that you would rather spend more money to buy peace of mind.
