The invention relates to a cross-shaped lifting appliance with two lifting points capable of horizontally rotating and belongs to the technical field of lifting appliances. The cross-shaped lifting appliance comprises a lifting appliance body; a lifting mechanism is arranged on the lifting appliance body; a plurality of lifting ropes are arranged on the surface, far away from the lifting mechanism, of the lifting appliance body; the lifting mechanism comprises a balance rod and steel wire ropes movably arranged at the two ends of the balance rod; and a rotating assembly is arranged between thebalance rod and the lifting appliance body. Due to the arrangement of the steel wire ropes movably arranged at the two ends of the balance rod and the rotating assembly, when the lifting appliance body rotates, the phenomenon that the balance rod drives the steel wire ropes to be distorted is not prone to occurring, namely, self-adaptive rotation can be achieved, so that the steel wire ropes canbe protected, and when a lifted component rotates, the steel wire ropes are not easily damaged; and the lifting appliance body can be kept in a vertical state all the time.
本申请涉及一种两吊点可水平转动的十字吊具,属于起重吊具的技术领域,其包括吊具本体,所述吊具本体上设置有起吊机构,所述吊具本体远离起吊机构的一面设置有若干吊绳;所述起吊机构包括平衡杆和活动式设置于平衡杆两端的钢丝绳,所述平衡杆和吊具本体之间设置有转动组件。活动式设置于平衡杆两端的钢丝绳,以及转动组件的设置,吊具本体在转动的时候,平衡杆不容易带动钢丝绳难以产生扭曲的现象,即能够自适应转动,从而能够对钢丝绳进行保护,被吊构件转动的时候,钢丝绳不容易产生损伤,并且吊具本体上能够始终保持竖直的状态。
