Block and Tackle with Four Pulleys
This example models a block and tackle with four pulleys. Torque is applied to a winch which acts through the pulley mechanism to lift a load. Blocks from the Simscape™ Multibody™ Belts and Cables library are used to model the block and tackle.

The plot below shows the torque applied to the winch and the vertical speed of the load. Note that for the first second, no torque is applied to the winch, but the load still moves due to gravity.
