The invention discloses a crane boom system and a crane, and belongs to the technical field of engineering machinery. The crane boom system comprises the crane, a main crane boom hinged to the crane, and a main boom head arranged at the end, away from the crane, of the main crane boom; the main boom head is provided with a luffing mechanism; a truss is arranged at the end, away from the main boom head, of the luffing mechanism; a winding wheel is arranged at the top of the truss; a first fixed pulley is arranged at the top of the truss; a first steel wire rope is wound on the winding wheel; the side, away from the winding wheel, of the first steel wire rope is slidably connected to the first fixed pulley; a weight is arranged at the end, away from the winding wheel, of the first steel wire rope; and the crane is provided with a limiting mechanism used for limiting the truss. According to the crane boom system and the crane, the truss can be limited through the limiting mechanism mounted on the crane, thus the truss is supported, the load of the main crane boom is reduced, and the safety and reliability of a hoisting system are improved.

    本发明公开了一种起重机臂架系统及起重机,属于工程机械技术领域,其包括:起重机,铰接于起重机的主起重臂,设置于主起重臂远离起重机一端的主臂臂头,主臂臂头设置有变幅机构,变幅机构远离主臂臂头的一端设置有桁架,桁架顶部设置有收卷轮,桁架顶部设置有第一定滑轮,收卷轮上缠绕有第一钢丝绳,第一钢丝绳远离收卷轮的一侧滑动连接于第一定滑轮,第一钢丝绳远离收卷轮的一端设置有重物,其中,起重机设置有用于对桁架进行限位的限位机构。本发明提供一种起重机臂架系统及起重机,能够通过安装在起重机上的限位机构对桁架进行限位,从而对桁架提供支撑,以减少主起重臂的负载,进而提高起重系统的安全性与可靠性。
