The invention discloses an upper single lifting point balance hanging beam and relates to a device used for transmitting lifting force to an object, in particular to a lifting device. The technical purpose that the balance of a single lifting point hanging beam is adjusted in an easy and convenient mode is achieved. The balance hanging beam comprises a hoop handle, a balance seat and a carrier bar. A lifting ring is arranged at the upper end of the hoop handle. The balance seat can slide along the carrier bar. The hoop handle is connected with the balance seat through a rotary shaft. After thelifting ring is lifted up, the end, with a smaller load, of the carrier bar rises up relatively, the other end of the carrier bar declines relatively, and the balance seat fails to slide upwards along the carrier bar; and after the lifting ring is lowered, while the carrier bar is changing into a horizontal state from an inclined state, the balance seat slides towards the end, relatively low, ofthe carrier bar. According to the inclination angle of the carrier bar, the lifting ring is operated to rise and fall, the balance seat slides to a balance position relative to the loads of the two ends of the carrier bar. According to the upper single lifting point balance hanging beam provided by the invention, balance adjusting saves time and labor and is safe, and the hanging beam is used forload lifting of a single lifting unit.
本发明为一种上部单吊点平衡吊梁,涉及一种用来传递提升力到物件上的装置,特别是涉及一种吊具;解决了对单吊点吊梁用简便方式调节平衡的技术问题。该平衡吊梁包括提梁、平衡座、承载梁,吊环设置于提梁上端,平衡座能沿承载梁滑动,提梁通过转动轴与平衡座相连接;提起吊环,承载梁负载小的一端相对升高,另一端相对降低,平衡座不能沿承载梁向上滑动;降下吊环,承载梁从倾斜状态向水平状态转变过程中,平衡座向上述承载梁相对降低的一端滑动。根据承载梁的倾斜角度,操作吊环上升和下降,将平衡座滑动至相对于承载梁两端负载的平衡位置。本发明的平衡调节省时、省力、安全,用于单个起重单元起吊负载。
