The invention discloses a shipborne single-arm rotary double-rescue boat crane system which comprises a rotary cargo boom with the rear end provided with a first boat lifting winch part and a second boat lifting winch part, the rotary cargo boom is provided with a fixed pulley, and a first boat lifting cable of the first boat lifting winch part is connected with a first lock catch part in a guiding mode through the fixed pulley; a second boat lifting cable of the second boat lifting winch part is connected with a second lock catch part in a guiding mode through a movable pulley. The rotary cargo boom is provided with a guide rail group; the movable pulley is arranged on the guide rail group through a pulley movable seat; the movable pulley is driven by the guide rail set to move along the rotary cargo boom, the position, for hoisting the rescue boat on the rotary cargo boom, of the second lock catch part is adjusted, and the transverse boat hoisting distance S formed between the second lock catch part and the first lock catch part is adjusted. By means of the design of the double rescue boat cranes, the boat lifting efficiency can be improved, the boat lifting distance can be adjusted through the movable pulley capable of moving on the rotary cargo boom, and safety, flexibility and convenience of boat lifting are guaranteed.

    本发明公开了一种船载单臂回转双救助艇吊系统,包括臂后端设置有起艇绞车一部和起艇绞车二部的回转起重臂,回转起重臂设置有固定滑轮,起艇绞车一部的第一起艇索经固定滑轮导向连接有第一锁扣部,起艇绞车二部的第二起艇索经活动滑轮导向连接有第二锁扣部;回转起重臂设置有导轨组,活动滑轮通过滑轮活动座设置于导轨组上;活动滑轮通过导轨组驱动沿回转起重臂位移,调整第二锁扣部在回转起重臂上起吊救助艇的位置,实现对第二锁扣部与第一锁扣部之间形成的横向艇吊间距S的调节。本发明通过双救助艇吊设计能够提高起艇效率,并且通过回转起重臂上可位移的活动滑轮能够调节起艇间距,保证起艇的安全性、灵活性与便利性。
