The safety part comprises a metal braking shoe (76) rubbing against a transmission belt (16) rotatingly integrated to the cutting tool when the safety part is in a rest position. The shoe is arranged apart from the belt when the safety part is in an activated position.

The invention discloses a grouped multi-axle trailer braking system, wherein, utilizing the characteristics of the four-circuit protection valve, the multi-axis trailer braking system is divided into multiple groups of independent 2-axis braking systems using the four-circuit protection valve. If an independent part of the brake pipeline is damaged, only the braking system of this group is affected, and the functions of other braking systems can still guarantee the braking function. In addition, the only manual parking valve is used to uniformly control the parking release control air circuit, so that Manual parking is still only controlled by the only manual parking valve, and an independent parking release air storage tank is also used. When the air source fails or other air storage tanks fail, it is guaranteed to have the function of releasing the parking brake at least once. With ABS anti-lock function, the braking function has strong reliability and stability, and the adaptive ability of different suspension loads and braking force reduces tire wear and improves the safety during driving.
