Winches look similar to regular teleporters, except instead of glowing green pads, they have metal prong-like pads with orange light coming from them. They also have a small arrow pointing at the orange light. They pair up with metal boxes that they pull when activated.
Similarly to how teleporters cause Dirk's chain to teleport to new places, when Dirk fires a chain into the winch teleporters, they shoot a chain at the box. However, they pull the box toward the exit to make another platform for Dirk. The box does not stop until it reaches the winch exit. If the winch is on a wall, this could crush Dirk.
