The invention discloses a gantry crane. The gantry crane comprises a lifting appliance system, a trolley frame and two pairs of stabilization units. A lifting winding drum is arranged on the trolley frame. Each stabilization unit comprises a stabilization winding drum, a stabilization rope, a swing pulley and a swing driving mechanism, wherein the stabilization winding drum is fixed to the liftingwinding drum and coaxially arranged with the lifting winding drum; and the stabilization rope sequentially bypasses the stabilization winding drum and the swing pulley to be steered and then is connected with the lifting appliance system. Portions, between the swing pulley and the lifting appliance system, of stabilization ropes are set as stabilization sections, the stabilization sections of thetwo paired stabilization units are located in different vertical planes, and projections of the two stabilization sections in the same X-Z plane are crossed; the swing pulleys of the two paired stabilization units are arranged at intervals in the X-axis direction, and the two pairs of stabilization sections are arranged at intervals in the Y direction; and the swing driving mechanisms are used for driving the corresponding swing pulleys to wind or unwind the ropes. The gantry crane not only can realize the functions of stabilization and lifting appliance tilting and rotation, but also has theadvantages of simple structure and low cost.

    本发明公开了一种龙门吊起重机,包括吊具系统、小车架和两对减摇单元,小车架上设有起升卷筒,减摇单元包括减摇卷筒、减摇绳索、摆动滑轮和摆动驱动机构,减摇卷筒固定在起升卷筒上并与起升卷筒同轴布置;减摇绳索先后绕过减摇卷筒和摆动滑轮转向后连接吊具系统;设摆动滑轮到吊具系统之间减摇绳索为减摇段,成对的两个减摇单元的减摇段位于不同的竖直平面内,且两个减摇段在同一X‑Z平面内的投影交叉;成对的两个减摇单元的摆动滑轮沿X轴方向间隔布置,两对减摇段沿Y方向间隔布置;摆动驱动机构用于驱动相应的摆动滑轮收绳或放绳。该龙门吊起重机不仅能实现减摇、吊具倾转和回转功能,而且还具有结构简单和成本低的优点。
