There are several commercial and industrial buildings that now exceed sixty stories or more. These buildings all need tall cranes to be able to help move the supplies to the upper floors. There are cranes which are operated from the back of trucks or other kinds that have their own vehicle connected. Tower cranes are the biggest types offered on the market.
Tower cranes are the stand-alone structures which are often seen on high-rise building projects. Usually, they are part of a major city's downtown skyline. Wherever new construction like for example skyscrapers or apartment buildings and commercial facilities like shopping center are being constructed, odds are a crane would be on site.
Kinds
The two major kinds of cranes could be distinguished by the way in which their jib or boom lifts materials. The jib is the metal frame that extends from the main section. On a flat tower crane, the jib remains horizontal when it lifts things. On a luffing type of tower crane, the jib could ratchet to upward or downward angles. The lifting capacity for both types could range from thirty thousand pounds to 10,000 pounds
Body
The body of the crane is composed of a vertical steel mast that is composed of separate sections. The sections are added to be able increase the overall height of the machinery. The mast extends upward to where the desired height is, to the control module, that is a small room which has glass windows on all four sides or to the tower as it is also called. The crane driver works from inside of the tower.
Lift
In order to lift materials, the crane utilizes a braided metal cord. The cord extends all the way to the end of the jib or boom from a motor located near the control module. There is a pulley system located at the end of the jib, through which the cord is positioned and lowered down. The jib that holds the cord becomes balanced by a counter jib located on the opposite side of the tower. The counter jib holds weights. These weights help to prevent the crane from tipping over when raising heavy supplies.
The hydraulic truck crane is a particular mobile crane which utilizes hydraulic power to raise and transport thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing in opposite directions on the pistons of the boom so as to lift thousands of pounds. Hydraulic truck cranes are essential in constructing major projects like for example bridges, airports, roads and buildings. A crane could accomplish in minutes tasks which will normally take hundreds of men and a lot of hours to accomplish.
The great machines are usually used in the building of cities, homes, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably constructed using basic cranes to allow the heaviest materials in one of the most awesome construction projects ever.
The very first representation of a crane was showcased during King Ramses' reign within Egypt in 3000 B.C. This was a portrayal of a lifting mechanism which was utilized to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized to create a whole country throughout the 5th century B.C.
Initially, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they needed something stronger and larger did these machinery evolve. Hick & Rothwell developed the first cast iron cranes during the year 1834, in Bolton, England. This machine can lift as much as 2 tons. That same year, wire ropes were added to the crane by Herr Albert Sr. who was an Official of the German Superior Board. The wire rope made the crane stronger and more durable. This addition enabled cranes to have a bigger capacity for lifting heavy weights.
Eventually, the wire ropes were weaved together in order to form an even more powerful strength. This wire formation also brought the added advantage of flexibility. 4 years later, Germany began to make cast iron cranes. The first cast iron crane built by Germany was made in Neuburg.
