Yes, gasoline engine mini dumper trucks can be used to transport sharp materials such as sand, gravel, and building materials, just like the "Little King Kong" on the construction site. The bucket and body structure of this type of vehicle have been specially treated with "anti-puncture and anti-wear", such as using thickened steel plates and wear-resistant coatings, so that the bucket is like wearing a layer of armor, even if it is loaded with angular stones or steel bars, it is not easy to be scratched or deformed. The track design can also disperse the pressure to prevent sharp materials from puncturing the tires or sinking into the mud.
However, it should be noted that although it can withstand daily "hard collisions", it still needs to be well maintained for long-term transportation of sharp materials. For example, broken iron pieces in sand and gravel may get stuck in the gap of the hydraulic rod, and they must be cleaned regularly; if the anti-wear coating on the inner wall of the bucket is scratched, it must be repaired in time, otherwise it will rust through and a new bucket will have to be replaced. In addition, don't overload for the sake of convenience-some drivers think that "the car is small anyway, it's okay to load half a ton more", but they end up crushing the chassis or hydraulic system, and the repair is more expensive than the freight.
Generally speaking, this type of mini dumper truck is like a "small expert on the construction site". It can easily move bricks and gravel, but you need to take care of it like a tool truck. Take your time when loading it, flush the mud and check the parts after use. It can accompany you to do dirty and tiring work for many years.
