Who Else Wants To Know How A Tower Crane Works?

Among the various kinds of cranes, tower cranes are the most prominent. They are commonly found at any construction areas.

In general, tower cranes are used to haul up, transport, and drop materials most commonly of heavier substance. These mechanical devices are generally used in the production of heavy equipment and in the construction business. Hence, tower cranes are commonly found at almost every construction site.

Experts say that a tower crane is the contemporary type of a balance crane. With its high post fastened to the ground, tower cranes frequently provide the finest arrangement of lifting ability and elevation. No wonder why tower cranes are commonly used in high edifices and tall building constructions.

Like a balanced beam, tower cranes have a long post fixed to the ground and an arm horizontally mounted and balanced disproportionately crosswise at the pinnacle of the tower. The long arm holds the “lifting gear” while the short arm holds a ballast of “concrete blocks.”

Now, the question lies on the actual operation of the tower crane. Considering the fact that the overall device is mounted only on a single high post, with no support on either side, the actual bearing of the weight of heavy objects is pretty amazing.

So how does a tower crane really works? The Concept

To understand how tower cranes work, it is important to learn the fundamental parts of the tower crane first. Regardless of their functions, different types of tower cranes have bases that are safely fastened on a huge solid pad. In essence, these bases serve as the main support of the tower crane.

Connected with the base is the tower or the mast. This mast provides the overall stature or elevation of the tower crane.

Then, connected to the upper portion of the tower is the “slewing unit.” This consists of the motor and the gear. This device enables the crane to revolve at any direction.

This remarkable combination of technology and intelligence enabled the tower crane to effectively lift, transport, and drop heavy materials without difficulty. Although the operation is managed by a cab operator, the tower crane is, by any means, technical.

Consequently, since tower cranes primarily deals with the huge boulders of concrete blocks or any weighty materials, the allowed or required weight capacity is extremely important.

Normally, a tower crane can carry load as much as 39,960 pounds. Any object heavier than this will not be accommodated.

However, experts say that it is not advisable to carry an object with this amount of weight if and only if the weight is placed at the end of the jib, or that portion of the crane that holds the lifted material. The point here is that the shorter the distance between the weight and the mast, the heavier the tower crane can haul up carefully.

Cab operators are employed to this kind of job. They are the ones responsible in maintaining the allowed number of weight. He also sees to it that the crane is not overloaded to avoid accidents and destruction.

Elements of Strength and Stability

Many people are wondering how tower cranes can stand the insistent pull of gravity and withstand the weight it holds in spite of the fact that it does not have any kind of support cables or chains around it.

To understand this more, here are some of the aspects that you have to consider. 1. Solid pad

The solid pad serves as the main support of the tower crane. This pad is usually built more than a few weeks before the tower crane is installed.

Here, big fasten bolts are set deep into the concrete pad to hold up the bottom of the tower crane.

2. Structure

The tower crane is not created as a one whole device. In spite of its height, the tower crane is still built part by part prior to its actual operation.

In essence, the weight of each mast is supported by the previously built mast. Hence, the overall weight of the device is not solely dependent on the base. Each mast supports each other, thereby, giving the whole tower crane a solid strength.

Indeed, a tower crane is quite an attraction in a particular construction site. With its remarkable attributes, almost anybody who sees it will be amazed.
