Modern urban landscapes would not be possible without the invention of the tower crane. Since 1949, when Hans Liebherr created the first tower crane, cities across the world have relied on the heavy lifting crane to make worksite projects quick, safe, and efficient.

In this tower cranes guide, we will explore the basics of how these important devices work. We’ll even answer a popular question: Why don’t the cranes fall down or tip over?

How Do Tower Cranes Work?

Tower cranes soar up to 265 feet into the air and can lift up to 20 tons. Regardless of their stature, tower cranes basically have the same three parts.

Keeping each tower crane from tipping over is a base that crews bold to the concrete below. Crews then connect the base to a mast or tower.

The slewing unit attaches to the base. The unit has a motor and ring gear. The gear allows the crane to rotate.

The working arm (jib) carries the load. A trolly runs along the long arm and moves the load. The operator uses counterweights to lift heavy loads up to where they need to be lifted.

Last but not least, the operating cab allows a trained professional to maneuver the massive crane in a delicate choreography.

How Are Tower Cranes Constructed?

Putting together a tower crane is hard work. First, construction project managers may need to explore a tower crane buying guide or search “tower cranes near me.”

Tower cranes keep from falling over because they are bolted to a large, concrete slab. This slab may need to be poured weeks before a tower crane can be set up.

A mobile crane helps move the sections. The crane then grows one mast at a time.

The crew attaches a top climber between the slewing unit and the upper end of the mast. A hydraulic ram then lifts the mast 20 feet at a time.

The process is slow work.

While all tower cranes consist of the same basic components, crane operators use specialized designs for certain types of projects. Luffing cranes, for example, can raise loads at an angle to reduce the slewing radius.

Derrick cranes fit on rooftops. They do not require tall masts. Traveling tower cranes move on rails that allow the cranes to move laterally.

Do I Need a Tower Crane?

If you are working on a project that requires lifting materials to very high heights then you will require a Hiab crane to complete your work.

Tower cranes can lift and set steel at every level of your project. They can be used to pour concrete or set panels in place. They also can help with the placement of electrical and mechanical systems.

How Technology Has Changed the Logging and Forestry Industry How Technology Has Changed the Logging and Forestry Industry Did you know that forests cover 31% of our planet’s landmass ? However, foresters only manage 6% of the woodland on Earth. Traditional practices make it hard for experts to explore other parts of the forest. Forest management requires a big budget and extensive labor. With this, experts produced equipment to use. Using advanced technology in forestry made the process faster and easier. Continue reading to find out the effects of technology in forestry. 1. Better Management The application of technology helps people determine the proper forestry practices. Some of the equipment used are satellites, drones, and scanners. Geospatial analysts use a satellite to check the state of the forest. They can determine if trees are new or not. The professionals can find out if an area is apt for agriculture as well. The use of drones in forestry makes data collection e

How Do Cranes Get Built on Skyscrapers? How Do Cranes Get Built on Skyscrapers? New York is famous for its skyscrapers, and the 10 tallest NYC buildings all stand over 1,000 feet . Cranes are one of the most important components of building skyscrapers, but you may find yourself wondering “how do cranes get built?”.  For tall buildings such as skyscrapers, standard cranes don’t quite cut it. Other types of cranes, such as knuckle boom cranes , are far more versatile. They’re also easier to set up but are limited in ways tower cranes are not (i.e. size and load capacity). This crane building guide gives an overview of how tower cranes are built on top of skyscrapers. How do Cranes Get Built on Top of Skyscrapers? Cranes have several purposes such as forestry, railway construction, and waste management . The place they are most commonly seen, however, is in built-up urban areas. There are specific types of cranes and methods for building skyscrapers. There are three main methods

Crane Hand Signals You Need to Know Crane Hand Signals You Need to Know When operating a crane, it can be difficult to hear other workers in your general vicinity. If only verbal cues are used, there would be a lot of “what?” shouts back-and-forth. So, it is necessary to have other means of communication to keep everyone safe. Having non-verbal communication can also help a project run more smoothly. Before starting up an operation with a crane, make sure that you and your team know these important crane hand signals to keep everyone safe. Stop Crane Hand Signals From 2011 to 2017, the Bureau of Labor Statistics reported that there were 297 deaths involving cranes . Out of those deaths, over 20% involved the crane operator. This highlights how crucial it is to brief all personnel around the worksite on safety procedures. Some of the most important hand signals to assure safety are stop hand signals. The top three stop signals are Stop Emergency Stop Dog Everything The stop
