The First of all over mind tower crane is highest height of crane in the world. Tower crane is a fixed on the construction site. Than tower crane vertical metallic structure to horizontally set the angel at 360°.
Tower crane only used for the high building and high structure constructions. It is also used in the maritime industry for loading and unloading boat merchandises.
The construction group utilizes the tower crane to lift steel, solid material, expansive instruments like lights and generators, and a wide variety of other structure materials.
Main Parts of Tower Crane
The actual base of the crane is concrete support pad with massive bolts. In concrete Pad is most important part in construction site and stability of tower crane. That crane pad approximately 30 feet by 30 feet and four feet deeper, and weighing approximately around 400,000 pounds.
Crane based connection is mast (Tower). The huge tower is ventures far out of sight, now and then as much as 265 or more feet.
Slewing Unit is attached top of the mast. They enable to crane rotate.
Attached with slewing unit is the jib. The long horizontally Jib (Working arm) is carries the load for the crane. The trolley runs jib load in and out from the crane center.
Actually it is shorter arm, they available opposite way of the jib. It contains the massive concrete counterweights that allow for balance when extending out heavy loads along the jib.
Tower Crane Work
Normally Tower crane actual height is 265 feet tall. We cannot used 250- foot jib much more height with heavy weight, because it not safer. Tower crane maximum jib reach is 230 feet; maximum weight lift is 19.8 tons, or 18 metric tons.
Tower crane have come on limited switches. One of the switch monitoring the load, it cannot exceed the 18-metric ton limit. A second switch for the load, depending upon the weight, does not extended distance along with the jib.
Tower Crane Capacity:
Maximum unsupported height: 265 feet
Maximum capacity of reaching: 230 feet
Maximum lifting power : 19.8 tons
Counterweights: 20 tons
Advantages of Tower Crane
The loading and lifting capacity crane in the world.
Their height of the capacity can’t be matched any other type of crane.
They incredible stability and hardest tasks.
Disadvantages of Tower Crane
These cranes are very expensive and they require time.
Maximum cost utilized to be shifted from one area to another.
They have high maintenance cost for repairs and depreciation.
They have a major labor-intensive to install.
Brand of Tower Crane
High industrial construction sites only used this type of crane. That is considering cost and efficiency of tower crane higher.
Application of Tower Crane
