Some industrial and commercial buildings could reach heights of over 60 stories. Apparently, while these buildings are being built, they require equally tall cranes to move the materials to the upper floors. There are cranes that have their own vehicle connected or other types which are operated from the back of trucks. Tower cranes are the largest kinds on the market.
Tower cranes are stand-alone structures seen as part of a major city's downtown skyline on high-rise building projects. Wherever new construction like for instance apartment buildings and skyscrapers and commercial facilities like for example shopping center are being constructed, chances are a crane will be on site.
Types
There are two different types of cranes: boom crane or the jib crane. The jib is a metal frame which extends from the main section. On a flat tower crane, the jib remains horizontal as it carries items. On a luffing kind of tower crane, the jib can ratchet to upward or downward angles. The lifting capacity for both kinds could vary from thirty thousand pounds to 10,000 lbs.
Body
The crane's body is composed of a vertical steel mast which is composed of individual sections. The parts are added to be able increase the overall height of the machine. The mast extends upward to wherever the desired height is, to the control module, that is a small room that has glass windows on all four sides or to the tower as it is also referred to. The crane operator works from inside of the tower.
Lift
The crane uses a braided metal cord to raise supplies. This cord extends out from a motor situated near the control module to the end of the jib or boom. There is a pulley system situated 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 situated on the tower's opposite side. The counter jib holds weights. These weights help to prevent the crane from toppling over when heavy materials are lifted.
Hydraulic truck cranes are a particular type of mobile crane. These cranes use hydraulics and are able to lift thousands of pounds. Hydraulics uses forces being transmitted through oil pushing on the pistons of the boom in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are important in constructing major projects such as bridges, airports, buildings and roads. A crane can accomplish in minutes tasks that will normally take hundreds of men and many hours to complete.
The great equipments are commonly utilized in the construction of cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely built using basic cranes to allow the heaviest materials in one of the most remarkable construction projects ever.
The very first cranes were established in 3000 B.C. Egypt in King Ramses'' reign. This lifting mechanism was first utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These mechanism were utilized to create a whole country throughout the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes started to change when dockyards began to require stronger and larger machines. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, during the year 1834. This machinery was capable of lifting as much as 2 tons. That very 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 larger capacity for lifting heavy weights.
The wire ropes were weaved together forming a more powerful rope with even more strength. The newly formed wire also added more flexibility. 4 years later, Germany started to make cast iron cranes. The very first cast iron crane made by Germany was built in Neuburg.
