CRANE EQUIPMENT (MACHINE HISTORY)

ORIGINS OF THE MODERN DAY CRANE

The principles of operation of today's CRANE EQUIPMENT is taken for granted, however, we thought you might be interested in learning a bit about the history of the Crane and its development into the modern age of technology.

CRANE EQUIPMENT AND CONSTRUCTION OF THE PANAMA CANAL 

A PICTORIAL HISTORY OF THE CONSTRUCTION OF THE PANAMA CANAL

 CONSTRUCTION WORKERS ON THE PANAMA CANAL

The building of the Panama Canal was one of the most grandiose, dramatic, and sweeping adventures of all time. Spanning nearly half a century, from its beginnings by a France in pursuit of glory to its completion by the United States on the eve of World War I, it enlisted men, nations, and money on a scale never before seen. Apart from the great wars, it was the largest, costliest single effort ever mounted anywhere on earth, and it affected the lives of tens of thousands of people throughout the world. Some 60,000 workers took part in the Panama Canal's construction.  Most of the Canal's workforce during the US construction period in the early 20th century arrived in Panama from the West Indies, on board the steamship Cristobal.

The failed French attempt to build a trans-oceanic canal across the isthmus saw a large scale recruitment of labour from the West Indies.  The loss of life from yellow fever and malaria proved to be staggering.  Over 22,000 workers lost their lives during these years. Some West Indian workers decided to remain in Panama while others returned home.

The building of the Panama Canal under the direction of the American Panama Canal Company once more saw a large recruited work force. Panama's population was relatively sparse, and the Americans discovered that there was no surplus labour anywhere in the republic for the Canal's construction. It became clear that the higher grades of skilled labour would have to come from the United States, whilst for the rest of the workforce the islands of the Caribbean were a logical source.  However, the Caribbean governments were reluctant to allow recruiting, because at the end of the French period of construction, many of the West Indian labourers had been stranded in Panama, and they had to be repatriated at their governments' expense.

The Barbados government finally agreed to large-scale recruitment and eventually there were some 19,900 Barbadian labourers working on the Canal project. This was reportedly some 10 per cent of the population of Barbados, and nearly 40 per cent of the island's adult men. Later, workers were also recruited from Martinique and Guadeloupe. Jamaica refused to allow any recruiting, and placed a tax of one pound sterling on anyone wishing to work in Panama. This meant that the Jamaican workers in Panama were mostly skilled workers, as only they could afford the tax.

The Americans had originally favored English speaking workers from the British West Indies. They were hard workers who understood and spoke the language of the North American employer. They were also regarded as “cheap labor” and faced racial discrimination not only by North Americans but by Panamanians as well. As a result, West Indians built up their own “insular culture” separate from their Hispanic and American neighbors. Stressing the maintenance of their traditional ways, they also strongly believed that education would lead to greater advancements for them and their children.

During the early years of the building of the canal most U.S. citizens working on the canal preferred to be paid in gold. West Indians however were paid in silver. From this developed the classifications of a “gold” or “silver” employee. The terminology was eventually extended to all of the Canal Zone. It basically took the form of racial segregation similar to that at the time in the American south. Water fountains, rest rooms and other public facilities were designated “gold” or “silver” and black and white communities in the Canal Zone lived in segregated communities.

Separate pay scales for blacks and non-blacks remained in force until the signing of the Panama Canal Treaty in 1977. The so called “gold” and “silver” classifications that were used to keep the canal segregated were discontinued in the 1960’s. But the “gold” and “silver” term of reference was still in use for many years after its official discontinuance, much to the resentment of the West Indian community.

During the building of the canal laborers by the thousands came from Jamaica, Barbados and Trinidad. By 1910 the PCC employed more than 50,000 workers, three-quarters of them were West Indians. When the canal was completed many of these workers stayed on to work for the Panama Canal Company. They made their homes in the American controlled Canal Zone as well as in and around Panama City. Only employees of the PCC were allowed to live in the Canal Zone. In all, another 100,000 people migrated to Panama during the construction era, adding to the diversity of Panama’s population.

 THE PANAMA CANAL IN 2009

The large work force that was deployed to aid in the construction of the Panama Canal and the use of various forms of crane equipment to assist in those efforts have earned their place in history and assisted greatly in bringing prosperity to Panama. Without their achievements and contribution, this engineering marvel would not have been possible.  Today tourism plays a big part in the economy of Panama and many people book cruises on passenger liners that traverse the Panama canal, the journey made possible by the thousands of construction workers employed to undertake the monumental task of its construction almost a century before.

 CRANE EQUIPMENT USED ON THE PANAMA CANAL TODAY    

On January 7, 1914, the Alexandre La Valley, an old French crane boat, became the first ship to make a complete transit of the Panama Canal.  In 2009 the Panama Canal is a busy and vital shipping route that uses giant overhead crane equipment for unloading cargo from ships.  Demand varies widely port by port, but the further development of crane equipment is required, cranes will need to get bigger and faster if they are to keep up with the expansion of container ships.

Demand for port crane equipment tends to be tied to the volumes going through the ports.  Business remains quite strong and is expected to get stronger with several ports stepping up expansions in anticipation of increased traffic through the Panama Canal in upcoming years. In 2005 the first of two crane equipment system orders (Twelve Rubber Tyre Gantry (RTG) cranes), totaling nearly $10 million dollars were delivered to the Port of Colon )Panama) for installation. The motors on this crane equipment are powered with ABB drives and electrical controls. 

Container Crane equipment is generally classified by lifting capacity, and the size of the container ships the crane can load and unload the containers with. "Panamax" crane equipment can fully load and unload containers from a container ship capable of passing through the Panama Canal (ships of 12–13 container rows wide).  "Post-Panamax" cranes can fully load and unload containers from a container ship too large (too wide) to pass through the Panama Canal ( normally about 18 container rows wide.) The largest modern container cranes are classified as "Super-Post Panamax" (for vessels of about 22 container rows wide and/or more). Modern container crane equipment capable of lifting two 20 ft (two 6 m) containers at once will generally have a rated lifting capacity of 65 tonnes from under the spreader. Some new cranes have now been built with 120 tonne load capacity enabling them to lift up to four 20 ft or two 40 ft long containers. Cranes capable of lifting six twenty foot containers have also been designed. Post-Panamax cranes weigh approximately 800–900 tonnes while the newer generation Super-PostPanamax cranes can weigh 1600–2000 tonnes.

The construction sector in Panama continues to be leading the growth of the national economy, A number of projects such as the $5.2 billion expansion of the Panama Canal; the possible construction of a regional refinery a major port on the Pacific; and the construction of a number of tourism and housing projects will keep the demand strong for heavy equipment and construction machinery for at least the next five years.
