Are there locks on the panama canal

With the help of Lock Gates, the vessels entering the canal are lifted to a higher level and later dropped down to the sea level at the other end of the canal. The Panama Water Lock System is considered to be one of the greatest engineering services undertaken at that time, purporting to the needs of the ships to save transit time. The Panama Water Lock System consists of a total of three sets of locks locks- to help vessels transit between the Atlantic and the Pacific Oceans via artificial lakes and channels.

Before the canal expansion , which was completed in , the canal had two lines with two sets of the lock at both ends of the canal. The expansion of the canal resulted in a third lane and a third set of locks that allow the entry of larger vessels. Since these three sets of locks are paired, two parallel flights of locks are located at each of the three lock sites, allowing the simultaneous movement of vessels in opposite directions.

However, in practice, only six massive pairs of locks are used by ships for transit now, and the ships move in one direction at a time due to safety constraints to cross the Culebra Cut. It also means that the ships currently use both lanes of the lock only to move in one direction at a time.

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. Hodges was an Army officer and an invaluable assistant to Goethals, had overall responsibility for the design and construction of the lock gates, arguably the most difficult technical responsibility of the entire project.

Goethals was to state that the Canal could not have been built without Hodges. Schildhauer was an electrical engineer and Goldmark was in charge of lock gate design. The key factor in the whole Canal enterprise, of course, was, and is, water. Water lifts ships 85 feet above sea level to the surface of Gatun Lake, floats them across the Continental Divide and lowers them again to sea level in the opposite ocean.

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.

As the lock gates themselves are a form of dam and above sea level, precautions were taken to protect them from damage that could allow the lake water to escape and flow out to sea. One measure was to have double gates ahead of the vessel, an operating gate and a guard gate, at points where damage to a gate could join the two levels, that is, at the upper and lower ends of the upper lock in each flight and at both ends of the Pedro Miguel single-step lock.

Also, iron fender chains were installed to stretch across the chambers between the lock walls to protect the guard gates. The Canal is a complex system that utilizes an artificial lake to help ships traverse between the Continental divide. Following is a transcript of the video. The Panama Canal is an engineering marvel.

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.
