Water also serves to generate electrical power for the Canal to run the electric motors that open and close the gates and valves and the electric locks locomotives. No pumps are used at the Panama Canal, the water does its work by force of gravity alone. Water is admitted or released through giant tunnels, or culverts, eighteen feet in diameter, running lengthwise within the center and side walls of the locks.
Branching off at right angles to these culverts, smaller culverts run laterally under the floor of each lock chamber, 20 to each chamber. Each cross culvert has five openings for a total of holes in each chamber for the water to enter or drain, depending on which valves are opened or closed.
This large number of holes distributes the water evenly over the full floor area to control turbulence. To fill a lock, the main valves at the lower end of the chamber are closed, while those at the upper end are opened.
The water pours from the lake through the large culverts into the cross culverts and up through the holes in the chamber floor. To release the water from the lock, the valves at the upper end are closed, while those at the lower end are opened.
The gates swing like double doors. The hollow, watertight construction of their lower halves makes them buoyant in the water, greatly reducing the working load on their hinges. All gate leaves are 64 feet wide by 7 feet thick.
However, they vary in height from 47 to 82 feet, depending on their position. For example, the Miraflores Locks lower chamber gates are the highest because of the extreme variation in the Pacific tides. The simple, yet powerful gate operating mechanism was designed by Edward Schildhauer. In its design he had no established model to go by.
Yet every aspect of this critical mechanism had to be precision engineered and manufactured to work flawlessly and dependably. The gates had to swing easily, yet withstand enormous pressures. Each foot-diameter, horizontal-lying bull wheel is geared to an electric motor. When in operation, wheel and strut work like the driving wheel and connecting rod on a railroad locomotive to open and close the gates. At Miraflores Locks, each lock chamber, except for the lower locks, has a set of intermediate gates.
The purpose of these is to conserve water by reducing the size of the chamber, if the ship in transit is not one of the Panamax giants and be accommodated by a foot chamber. The original locks of the Panama Canal are The walls of each lock have a thickness ranges from 15 meters at the base to 3 meters at the top.
The dimensions of the lock decide the size of a ship, which is also known as Panamax- that can pass through the canal. The third set of locks opened after the expansion project allows bigger vessels to cross the canal. The new Panamax metrics, with the new locks, allows the ships with an overall length of meters, a beam of 49 meters and a draft of The total lift, the capacity to raise or lower a vessel, of the locks are; Gatun locks feet, Pedro Miguel locks feet and Miraflores- between The gates of the Panama Canal locks separate the champers, and are strong enough to hold thousands of litres of water.
The water locks are filled or emptied in less than 10 minutes and each pair of lock gates takes two minutes to open. The size of the Panama lock gates ranges from Each gate features two leaves that measure The gates are only opened when the water level is equal on both sides. A fender chain, weighing around 30, pounds, at the end of each lock prevents ships from ramming the gates before they open.
In order to let the vessels pass the lock, each chamber needs to be filled with 26,, US gallons of water. The lock system includes 18 feet wide water culverts attached to it, performing the duty of carrying water from these lakes to the chambers to raise the vessels and from chambers to the next lock or the sea to lower the vessels. Operated electrically, the entire process of the lock system is controlled from a control room located on the centre wall of the upper flight of locks. About 14, ships use it every year.
The canal is about 48 miles long. It functions as a waterway between North and South America. The canal connects the Atlantic and Pacific Oceans. Before the canal, ships had to sail 13, miles around the tip of South America An artificial lake across Panama connects the oceans. The Gatun Lake is 85 feet above sea level.
