so when a ship sinks you can get off of it instead of dying

Some accounts vary, but regarding Titanic survivors rescuing other people, it seems that: #14 (Lowe's boat) saved 4, (one died) and #4 saved 8, (two died).Captain Rostron buried four victims at sea but three of them were alive when they boarded the rescue ship and the fourth was already dead during the operation.

Lifeboat #7 was launched at 12:40 PM and the last survivor to board Carpathia, Second Officer Lightoller, climbed aboard at 8:10 AM the next morning.

Two of the sixteen lifeboats went back to find survivors. They found 9 people in the water but only 6 survived. The first boat, Lifeboat 4, pulled 5 people from the water but two died in the boat. The second boat, Lifeboat 14, found 4 survivors, but one died in the lifeboat.

When asked why they did not go back sooner to help people, Officer Harold Lowe, who headed Lifeboat 14, said "it would have been suicide to go back there until the people had thinned out." He was afraid that those drowning would have overturned or swamped the lifeboat.

Including passengers and crew, there were 2,208 people onboard. 1,503 people died, leaving 705 survivors. Only 962 lifeboat seats were required by law, though the Titanic's lifeboats could have held 1,178. There were 472 lifeboat seats that went unused.

The term you're looking for might be "winch". Or it might not, since "lifeboat lifter" is kind of a vague term, you may need to ask again but be more specific.

Lifeboats are carried on ships (which, by definition can carry a boat). Typically suspended for fast access, they are filled with passengers and lowered into water in times of peril on the sea.

There were 712 survivors of Titanic in the lifeboats.

Titanic's lifeboats were last accounted for in December 1912 and were left to rot, likely as not.
They definitely were NOT reused on any other vessels.
