Knuckle Boom Crane vs. Telescopic: What’s the Difference?

According to Global Markets Insights, the boom trucks market size exceeded $1.3 billion in 2019. Over the next five years, industry experts estimate the market to grow at a 4.5 percent compound annual growth rate (CAGR). This comes thanks in large part to urbanization and industrialization.

The choice for boom truck loader cranes often boils down to either a knuckle boom crane or a telescopic boom crane. Your selection should be based upon the intended use of the machine and your job requirements.

So here’s a look at important differences between these two pieces of equipment.

Telescopic vs Knuckle Boom Crane

With government infrastructure projects and private sector construction, spending in the boom truck market continues to grow. The demand for these trucks to help maneuver material and workers is increasing. They’ve proven themselves efficient and safe.

These types of cranes provide different advantages and disadvantages. It largely depends on your intended use and job site.

Knuckle Boom Crane

So, what is a knuckle boom crane? This machine gives project managers and contractors a versatile solution to their loading concerns. Sometimes called an articulating crane, folding crane, or loader crane, the knuckle boom provides precise maneuverability, fast loading, and compact storage.

The machine’s knuckle hinge allows for operators to retract and rotate the crane in a single movement. This combination of lifting and turning makes moving material more precise.

Knuckle booms have the ability to retract and expand at almost any angle. This allows the machine to move heavy cargo through confined spaces. The ease of loading and unloading material comes from the crane’s ability to complete various movements.

Operators prefer knuckle boom cranes for precise placement of material thanks to ease of use. And when not using the machine, the knuckle boom folds away, allowing for more loading space on the trucks.

Telescopic Crane

So, what is a telescopic crane? These machines are sometimes called straight boom cranes. They have a cable and hook, often attached to a winch. Telescopic cranes provide extended reach, with better vertical clearance, and are ideal for use with a winch.

The telescopic crane’s main advantage over a knuckle boom is its ability to provide a longer reach. The crane extends and retracts from the boom, allowing for adjustable vertical and horizontal length.

The crane lowers its cargo smoothly, which helps in moving potentially fragile material. The telescoping action comes in handy for operators who need to clear vertical obstacles while placing the cargo down. Getting over obstacles can be particularly useful in crowded job sites.

The main lifting a hauling device of these cranes is the winch. Although winches can be used with knuckle boom cranes, they’re better suited for telescopic cranes. Since the boom doesn’t bend, it provides sturdy support for the cable.

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
