Made 99.9% of LEGO, exceptions are PRINTED pulley wheels, stickers, strings etc. and 5kg of lead as ballast.
Slewing ring is made 100% of LEGO with minifig heads as rollers.
It is not glued!
About weight measurement. The value is too high AFTER lifting, and too low AFTER lowering due to friction in rope, pulley wheels etc. Acceleration is another thing that has meaning but only for a short time.
I do not have instruction.
