The invention relates to the technical field of building machinery, and discloses a safety module, a lifting system, a crane and a lifting method of the crane. The safety module comprises a driven piece (111) and a main body part; the driven piece (111) is used for being fixed between different steps (61); the main body part moves along the length extension direction of the driven piece (111); the main body part and has mechanical transmission reverse transmission self-locking performance with the driven piece (111); and the main body part comprises a driving piece (112) which forms a kinematic pair with the driven piece (111). Thus, by means of the self-locking characteristics of the main body part and the driven piece (111), the purposes that automatic protection can be achieved when faults occur in a jacking operation or descending operation process, and a load supported on the main body part is prevented from suddenly descending are achieved.
本发明涉及建筑机械技术领域,公开了一种安全模块、升降系统和起重机及其升降方法。所述安全模块包括用于固定在不同踏步(61)之间的从动件(111)和沿所述从动件(111)的长度延伸方向运动且和所述从动件(111)具有机械传动逆传动自锁性的主体部;所述主体部包括和所述从动件(111)形成运动副的主动件(112)。这样,利用主体部和所述从动件(111)的自锁特性,达到在顶升作业或者下降作业过程中出现故障的时能够起到自动保护、防止支撑在所述主体部上的负载突然下降的目的。
