摘要

 單臂救助艇/筏兼起重機(jī)主要由起重臂、回轉(zhuǎn)盤、液壓回轉(zhuǎn)裝置、起升機(jī)構(gòu)、蓄能器、手動(dòng)泵、回轉(zhuǎn)支承、限位裝置、遙控裝置、滑輪及起重機(jī)構(gòu)等組成。
 單臂救助艇/筏兼起重機(jī)符合MSC.47(66)-1974年國際海上人命安全公約的修正案及國際海事MSC.48(66)-國際救生設(shè)備規(guī)則中的有關(guān)要求。本單臂吊主要用來吊放救助艇/筏，也可用于降放符合不大于21KN的其他型式艇筏，另外，還可以當(dāng)起重機(jī)使用，要求起吊負(fù)荷不得大于15KN.吊筏裝置具有電動(dòng)（手動(dòng)）起升、重力下放、液壓回轉(zhuǎn)（泵站和蓄能器或手動(dòng)泵供油）功能，設(shè)有機(jī)旁操縱下放和回轉(zhuǎn)及艇內(nèi)遙控下放和回轉(zhuǎn)兩種功能。起重機(jī)為電動(dòng)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.
