The All-terrain crane is a high-performance product that combines the characteristics of a truck crane and an off-road crane.  It can not only transfer quickly and travel long distances like a truck crane, but also meet the requirements of operating in small and rugged or muddy sites, that is, fast travel speed, multi-axle drive, all-wheel steering, three steering modes, and ground clearance.  With features such as large clearance and high climbing ability, it is a product with great future development.The key in chassis design technology is the hydropneumatic suspension system and multi-axle steering system design. These two technologies are unique to all-terrain cranes.The braking safety performance of a vehicle, in addition to the structural composition of the braking system, the braking state of the vehicle and related conditions, is inseparable from the structural type and arrangement of the vehicle's traveling system. All-terrain truck cranes combine the characteristics of many engineering vehicles into one. The analysis of its braking safety performance is of typical representative significance.
