The Role of the Tower Cranes For Sale Australia In Projects

Any city's skyline will almost always feature a few tower cranes, which are among the most significant pieces of construction equipment. Tower cranes for sale Australia are used by construction businesses to lift large items like steel and concrete. Tower cranes are also used to move large items such as acetylene torches, motors, and generators. Because tower cranes are so little in comparison to high-rise structures, their lifting power is frequently overestimated. How is it possible to raise such a large amount of weight? Is the crane becoming taller as the design gets taller?

 

 

Tower crane parts

The base, the mast or tower, and the slewing unit are the three major tower crane components.

 

  1. The base: The crane's primary support is the base. It is supported by a massive concrete foundation that bears the whole weight of the structure.
  2. Mast or tower: The crane's height is determined by the supporting structure that connects the mast to the base. The crane's strength comes from a massive triangulated lattice structure on the mast.
  3. Slewing unit: The slewing unit, which is mounted to the top of the mast and allows the crane to revolve around its axis, comprises a gear and motor. The slewing team, on the other hand, is made up of three parts:
  4. Jib or working arm: A horizontal piece that carries the load and has a trolley along its length to transfer the weight in and out.
  5. Machinery arm: The load-lifting motor is held by the machinery arm, which is a shorter horizontal part. To maintain balance, it also has electrical controls, a cable drum, and concrete counterweights.
  6. Operator's cabin: This is the area where the crane operator controls all of the crane's operations.

 

Tower crane specifications

The following are the characteristics of a standard tower crane; however, note that they vary based on the type and manufacturer:

  • 265 feet (80 meters) is the maximum unsupported height. Because the structure rises around the crane, it may reach greater heights when linked to it.
  • 230 feet (70 meters) is the maximum reach.
  • Lifting capacity: 19.8 tons (18 metric tons)
  • 20 tons (16.3 metric tons) of counterweights

The crane's maximum load is 18 metric tons. However, when the load is at the end of the job, it can't lift that much weight. The more weight the crane can safely lift, the closer the load is to the mast. To avoid overloading, operators have two limit switches: a maximum load switch to keep the crane under 18 metric tons and an ultimate moment switches to safeguard the crane from the load's bending force.

 

Tower crane support system 

 When looking at a tower crane for sale Australia, one of the first concerns that come to mind is whether or not these constructions are stable. Several factors influence the tower crane's stability. The concrete pad is a foundation that was built by the building business several weeks before the crane arrived. The pad's typical dimensions are 30x30x4 feet (10x10x1.3 meters), weighing about 400,000 pounds. The crane's base is supported by large anchor bolts that are firmly sunk in the concrete pad.
