Water surface hoisting equipment

The invention discloses water surface hoisting equipment. According to the water surface hoisting equipment, two bearing ships are adopted as a foundation, a hoisting device is arranged between the two bearing ships, by adopting the design, the stability during hoisting operation can be improved, and the risk of inclination of the bearing ships is avoided. In addition, a guide pulley A and a guidepulley B are arranged in a gap between a cross beam A131 and a cross beam B132, that is, a supporting shaft of the guide pulley A and a supporting shaft of the guide pulley B are arranged between thecross beam A and the cross beam B in a stride-over manner. By adopting the design, a stress point can be located on the center line of a cross beam assembly, adverse phenomena such as side inclination are avoided, and stability is improved. 本发明公开了一种水面吊装设备，本发明的水面吊装设备采用两条承载船作为基础，将吊装装置设置在两条承载船之间，采用这种的设计，能提高吊装作业时的稳定性，避免出现承载船倾斜的风险；此外，导向滑轮A和导向滑轮B设置在横梁A131和横梁B132之间的间隙，也就是说导向滑轮A的支撑轴和导向滑轮B的支撑轴跨设在横梁A和横梁B之间，采用这种设计，能使受力点位于横梁组件的中心线上，避
