[0002] The hydraulic outriggers of truck-mounted cranes are a stabilizing system for light pickup cranes. With the development of the light pickup crane industry, all walks of life have higher and higher requirements for pickup trucks, especially for stabilizing systems. With the continuous development of science and technology, people's requirements for the manufacturing process of hydraulic outriggers of truck-mounted cranes are also getting higher and higher.

[0003] At present, the outriggers of light pickup cranes are all controlled by hydraulic operating systems, and the outriggers are all operated by multi-way valves, which are very convenient to use. When the outriggers are not firmly supported on the ground or fail, the hydraulic lock can shut off the hydraulic oil in time, which can better ensure the stability of the vehicle system, not only improving the stability of the vehicle system, but also facilitating installation. In addition to avoiding high danger, the frog-shaped hydraulic outrigger design will also avoid accidents that cause tire blowouts. Some outriggers use electronically controlled hydraulic valves and use remote control to control the outrigger movements, which greatly increases the speed of the vehicle, making it easy for customers to accept and conducive to market promotion.
