Hello thanks for vedio uploading... and in my ship crane there are hoisting noise when haveup loads thats sound do not genreate wothout load on hoisting can u please describe what is the causes for hoisting noise ??
with hydrolic hoist the noise will change under load because of resistance to fuild flow. the pump (not the part they took apart) works harder under load becoming louder and changing pitch as it pushes fluid to the hydrolic motor to spin the drum.
