Forward motion into and through the locks is actually provided by the ship's engines and not the mules. A ship approaching the locks first pulls up to the guide wall, which is an extension of the centre wall of the locks, where it is taken under control by the mules on the wall before proceeding into the lock.

    It's called a dam and lock system. Boats and ships get through a waterway by going into a lock, which is a big chamber in the water with moveable gates at each end, then waiting as a valve is opened and the water from that lock flows into the next lock (or next body of water if just one lock), raising or lowering the boat automatically. The may be scope to combine venture pumps with side tanks at navigation locks for the purpose of reducing water usage to transit ships. During filling of the lock, water may flow from side tank.

    Once the ship is lifted up, it reaches the Gatun Lake, which is a fresh water lake supplying water to the lock chambers, enabling the ships to be lifted up and dropping down. Then comes the Pedro Miguel locks, where it has one step, lowering the ship down. A lock or water lock is an enclosed, rectangular chamber with gates at each end, within which water is raised or lowered to allow boats or ships to overcome differences in water level. Locks have a history of over 2, years, and although they are most often used by boats on canals, they also are used to transport massive ships between seas.
