Descrição Geral

The Winch Mechanism, "MMEL", allows to study the lifting velocity and load transmission of a winch. Efficiency and load transmission can be determined by force balance.

The unit consists of a gear transmission mechanism. One gear is the input gear driven by a pulley (driving pulley) and the other gear is the output gear on whose shaft another pulley is attached (driven pulley).

Both pulleys have high resistance ropes wound on their periphery and end in a hook to attach the weights, allowing to exert a force or load. Through observations of the equilibrium moment, force transmission and performance can be determined.

The winch is equipped with a safety device.
