High-altitude vehicles are special special vehicles with a height of 3m or more that use hydraulic or electric systems to govern multiple hydraulic cylinders and can be lifted up and down to carry out work. The builders use the aerial vehicles to rise to high altitude as long as the driver presses. There are no safety risks in requesting operations. Aerial vehicles are widely used in power, street lighting, municipal, gardening, communications, airports, construction (repair) ships, transportation, advertising, and photography. The largest manufacturer of aerial working vehicles in China is the XCMG aerial work vehicle. The product types are complete and the technology is advanced. Here's a brief introduction for everyone.
