Tower cranes are machines used for lifting and moving heavy objects at large construction sites. With exceptional lifting and power capabilities, tower cranes are most commonly used for the construction of skyscrapers. A typical tower crane for sale is fixed and provides stable and efficient lifting operations. The stationary base gives the tower crane increased stability and efficiency. Consisted of a horizontal beam or jib and a mast section, the tower crane looks like the letter “T”.
All tower cranes Australia models have the maximum unsupported height of about 85 meters, maximum reach of about 75 meter, counterweight of about 15 tonnes and maximum lifting capacity of about 19 tons. The maximum weight these tower cranes for sale can lift is around 20 tonnes, but this is not the case if the load is attached at the end of the jib. The entire load needs to be attached to the mast in order for the tower crane to lift the load safely and efficiently. Tower cranes Australia models have a 300-tonne-meter rating. What does this mean? For instance, if the load is attached about 30 meters from the mast, the tower crane would be able to lift about 10 tonnes the most.
Most tower cranes for sale today are equipped with two-limit switches to ensure that the operator will not overload the tower crane. The first switch is called maximum load, and this switch monitors the pull of the cable and ensures the load does not exceed 20 tonnes. The other switch is known as load moment, and ensures that the operator of the crane does not exceed the tonne-meter rating of the tower crane as the loads moves off the jib. Also, most tower cranes in Australia include cat-head assembly in their slewing units. This assembly alerts when overload occurs.
All tower cranes for sale are important machines for the construction industry as they have the capability to lift large tools and equipment, large amounts of concrete and similar heavy construction components. They are also efficient in other industries where heavy loads need to be lifted and moved from one location to another. It is very easy to recognize a tower crane because it is one of the largest construction machines.
