Construction means heavy lifting. And for this, heavy-lifting staples are essential. The staples help the workers to tackle the on-site tasks effortlessly. One of those staples is tower cranes.
Today, you won’t find a construction site without a single tower crane. And if it’s not there, it means the construction project is not large-scale. The majestic skyscrapers of modern cities, their bridges, elevated railways, and others are all because of the tower cranes.
How do tower cranes help in the construction site?
A tower crane has never-ending towers that rise hundreds of feet above the ground just like every major city’s skyline. The tower crane is beneficial when your project requires heavy lifting at extreme heights. The tower can lift all the materials on the construction site to the required height easily and conveniently. Even carrying bulky equipment around is possible with a tower crane.
A tower crane is important at the construction site. But, buying it might impact your construction budget significantly. Therefore, look for a reputable crane company and take a tower crane for rent.
Types of tower cranes
Hammerhead tower crane
Feature with a fixed, horizontal job and a trolley assembly, the hammerhead tower crane travels the length of the jib to position the hook. There are hammerhead tower cranes that utilize pendant lines between the jib or counter jib and a tower top. Other hammerhead tower cranes utilize a “flat top” design without a tower top or pendant lines. The last hammerhead tower crane is used when multiple cranes swing through the same airspace.
Luffing Jib Crane
Also known as luffer, the luffing jib crane is especially used on tight job sites. The crane utilizes a jib that rotates up and down with the hook fixed to the end of the job. By luffing the jib up or down, the hook is positioned.
Self-Erecting Crane
Compared to other tower crane types, the self-erecting tower crane is small. Without the assistance of any other crane, the crane erects on the site. The crane extends its mast and then unfolds its jib via hydraulic cylinders permanently fixed to it. The only disadvantage of self-erecting cranes is that they are appropriate for smaller or shorter-duration projects. It’s because the crane can’t be tied to the structure and has limited hook heights.
Is it safe to work with a tower crane at the construction site?
Often, the tower crane seems to be leaning. It’s true but nothing to be concerned about. It’s because the steel used in the construction of the crane is strong and rigid along with some flexibility. You see the crane leaning because of the flex in the steel because various loads are balanced against each other.
The tower crane works like most cranes, that is, on leverage and balance. The only thing is that a tower crane is a lever on top of a lever.
A tower crane is important at the construction site for easy and risk-free construction. So, whether it’s a small-scale or large-scale construction project, connect with a crane company for a tower crane rental.
