The invention discloses a silent single-beam European style crane. The crane comprises a cross beam, wherein a mounting frame is movably arranged at the bottom of the cross beam; a telescopic outer rod is movably arranged on the mounting frame; a telescopic inner rod is movably arranged at the inner side of the telescopic outer rod; two auxiliary connecting arms are arranged below a main connecting arm; and two electromagnetic chucks are fixedly arranged at the bottom of the auxiliary connecting arms. By arranging a first electromagnet, a first coil winding, a second electromagnet and a second coil winding, a movable rack is kept stable in the running process, a first pulley and a second pulley are prevented from colliding with a track, and noise is avoided; the movable rack and the track are wrapped through the cross beam, sound is effectively isolated, and the sound is absorbed through a sponge plate in the cross beam, so that the silence performance of the crane is greatly improved; the telescopic outer rod and the telescopic inner rod are high in stability in the carrying process, the possibility of collision is avoided, and sound is prevented; and the crane can meet the carrying requirements of objects at different positions and is wide in applicability.

    本发明公开了一种静音式单梁欧式起重机,包括横梁,横梁的底部活动安装有安装框架,安装框架上活动安装有伸缩外杆,所述伸缩外杆的内侧活动安装有伸缩内杆,主连接臂的下方设置有两个副连接臂,副连接臂的底部固定安装有两个电磁吸盘;通过设置电磁铁一与线圈绕组一以及电磁铁二与线圈绕组,使得移动架在行驶中保持稳定,避免滑轮一、滑轮二与轨道发生碰撞,避免产生噪音,通过横梁对移动架与轨道形成包覆,有效隔离声音,并通过横梁内部的海绵板吸收声音,大大提高了该起重机的静音性能,搬运过程中伸缩外杆和伸缩内杆稳定性高,不会存在碰撞的可能,防止产生声响,该起重机可以满足不同位置物品的搬运需求,适用性广。
