摘要

 单臂救助艇/筏兼起重机主要由起重臂、回转盘、液压回转装置、起升机构、蓄能器、手动泵、回转支承、限位装置、遥控装置、滑轮及起重机构等组成。
 单臂救助艇/筏兼起重机符合MSC.47(66)-1974年国际海上人命安全公约的修正案及国际海事MSC.48(66)-国际救生设备规则中的有关要求。本单臂吊主要用来吊放救助艇/筏，也可用于降放符合不大于21KN的其他型式艇筏，另外，还可以当起重机使用，要求起吊负荷不得大于15KN.吊筏装置具有电动（手动）起升、重力下放、液压回转（泵站和蓄能器或手动泵供油）功能，设有机旁操纵下放和回转及艇内遥控下放和回转两种功能。起重机为电动起升和下降。

Abstract

 The single arm rescue boat/raft davit & crane mainly consists of jib, hydraulic slewing device, hoisting mechanism, accumulator, manual pump, slewing bearings, limit device, remote control device and head blocks as well as lifting mechanism etc.
 This single arm slewing boat/raft davit conforms to the requirements of MSC.47(66)-Amendments to SOLAS 1974 and MSC.48(66)-Rules for Lifesaving Appliance.
   The slewing davit is mainly used for lifting and lowering a boat/raft, and also for other types of raft davit whose lowering load not more than 21 KN. Additional, it is also acted as crane , whose lifting load should be required not more than 15 KN. It have the functions of electrical(manual) hoisting, gravity lowering, hydraulic slewing (Oils fed from the pump station or accumulator/manual pump). It is provided with lowering and slewing functions operated from deck or remotely controlled from a position within the boat/raft.
