A system for a crane cylinder actuator having first and second chambers, a piston separating the first chamber from the second chamber, the system comprising: a first feed tube to the first chamber; the second feeding pipe is arranged in the second chamber; the system may be connected to a distribution valve configured to alternately supply one of the first feed pipe and the second feed pipe and discharge the other of the first feed pipe and the second feed pipe; a first non-return system located along the second feed pipe and configured to open a passage for fluid from the dispensing valve and directed to the second chamber, the first non-return system being connected to the first feed pipe by a first guide pipe; the second feed pipe comprises a main branch pipe and an auxiliary branch pipe, the first non-return system is located along the main branch pipe, the auxiliary branch pipe is parallel to the main branch pipe, the second non-return system is located along the auxiliary branch pipe, and the second non-return system is configured to enable the pressure in the second guide pipe corresponding to the second non-return system to reach a second threshold value when the pressure in the second guide pipe corresponding to the second non-return system reaches the second threshold value. A passage from fluid for the second chamber and directed to the dispensing valve is opened.

    用于起重机气缸执行器的系统,具有第一和第二腔室、将第一腔室与第二腔室分开的活塞,系统包括:第一腔室的第一进料管;第二腔室的第二进料管;系统可连接到分配阀,其被配置为交替供应第一进料管和第二进料管之一并排放第一进料管和第二进料管中另一个;第一止回系统位于沿第二进料管上并配置为打开用于来自分配阀并被引导至第二腔室的流体的通道,第一止回系统通过第一引导管连接到第一进料管;第二进料管包括主支管和副支管,第一止回系统位于沿主支管上,副支管平行于主支管且第二止回系统位于沿副支管上,第二止回系统被配置为当与第二止回系统对应的第二引导管中的压力达到第二阈值时,打开来自用于第二腔室并被引导至分配阀的流体的通道。
