A Breakdown of Concrete Demolition Equipment

When most people think of demolition, they might picture wrecking balls and TNT. While these may make great movie scenes,  not all demolition is as cinematic. Concrete demolition uses a variety of specialized power equipment to get the job done.

 

Types of Concrete Demolition Equipment

Demolition Robots

Demolition robots are remote-controlled machines used in the concrete demolition process. They provide a quicker, easier, and safer way for breaking up concrete. But, with such a specialized tool comes a hefty price tag. These robots can range in price anywhere from $165,000 to $220,000 and up.

 

Excavator Attachments

In some projects, demolition robots simply aren’t enough. The complexity of certain structures requires additional aid. Excavator attachments are external tools that attach to the head of the machine. They function as a specialized extension to access harder-to-reach areas. There are various different kinds of attachments, each with its own purpose.

 

 

Hydraulic Breakers

Hydraulic breakers are primarily used to reduce shock loads and vibrations. With a large hammer built in the center, hydraulic breakers function much like jackhammers. They are able to powerfully strike the concrete while keeping less stress on the machine. Some have monobloc designs that protect against linkage strain due to repetitive use. Most breakers are fit onto skid-steers, excavators, backhoes, and track loaders for transportation.

 

Concrete Crushers

Many say concrete crushers resemble a large mouth with jagged teeth. And in some ways, they function rather similarly. These demolition tools have a very powerful set of jaws that can break down dense concrete structures. Concrete crushers focus on the separation between the concrete and the steel bars. They are used for both primary and secondary demolitions.

 

 

 

Multi-Jaw Demolition Tool

Multi-Jaw demolition tools are modified concrete crushes. Instead of having a top and bottom set of “teeth”, they have 3. One set sits at the top and the other two are on the bottom. The extra set allows the machines to demolish more concrete, quicker. 

 

Concrete Cutters

In some projects, the goal is not so much to crush concrete, but rather to cut it instead. Cutting concrete is a more precise process than demolishing. Concrete cutters are attachments that can cut through both steel and concrete. Cutters of this type are used in primary and secondary demolitions sites. The attachment can rotate 360 degrees to reach any angle. For tougher projects, they can come with hydraulic cylinders which used pressurized fluid to generate more force.

 

Rotary Drum Cutters

Rotary drum cutters are similar to concrete cutters in that they both aid in the cutting process. But the method in which they cut concrete differs. While concrete cutters function like scissors, rotary drum cutters act more like a pizza cutter. They have a set of wheels with sharp metal spikes that spin at thousands of RPMs. The speed and power of these tools help to cut through dense slabs.

 

Concrete Removal

 

After concrete demolition comes concrete removal. Often the burden of cleaning the concrete falls on the demolishing company. Moving large, heavy chunks of concrete can be both difficult and costly. To efficiently clear the demolition debris, most companies use a specialized set of tools.

 

 

Multi Grapples

One of the more challenging aspects of removal is dealing with the weight of the concrete debris. Multi Grapples are likened to giant versions of the claws in the arcade claw games. To use them, they attach to demolition robots or other construction equipment. This way they can be steered and directed to the area of clean up.

 

 

Skid Loaders

Skid loaders are another essential tool for concrete removal. They act much like large, driveable shovels. When choosing the right skid loader for your project, consider the estimated weight of the rubble. Skid loaders come in different sized frames, each equipped to handle only a certain amount of weight. Many models range from small, holding up to 1,750 lbs, to large, holding up to 2,200 lbs.

 

Additional Costs to Removing Concrete

In addition to the costs associated with the concrete removal machines, there are added expenses to account for. Aside from the actual machine price, the maintenance of the machinery, as well as the labor, are to be considered. Machine upkeep like cleaning and tuning must be kept up to date for safety purposes. In terms of human labor, ensuring that payments are up to labor and union standards is important.

 

Other Methods of Concrete Demolition

 

 

The Traditional Ball and Chain Method

While there have been major advances in machine technology, some projects still use traditional tools. The ball and chain method has stood this test of time. The process is simple. A roughly 14,000-pound wrecking ball is swung from a crane to tear down a large structure. This method is often used in conjunction with other more modern processes.

 

 

Jackhammer

For smaller projects, jackhammers are a useful aid. These handheld tools are both far less powerful and expensive than demolition robots. For this reason, jackhammers are an excellent, price-conscious tool for smaller needs. Additionally, because they’re smaller, they’re used in areas when large machinery would be a hindrance. This is why often jackhammers are used to break up roads in trafficked areas.

 

Recycling Concrete

In a push for a more sustainable practice, many job sites have been recycling concrete. The crushed debris, known as recycled aggregate, can be used again in other projects. Oftentimes they are used as the base for new roads, parking lots, and driveways. Additionally, if any project needs a sort of filler, these little crumbles are perfect for the job. 

Recycling concrete reduces both waste and landfill costs. It helps avoid adding excess materials to waste sites. Additionally, it helps save money in purchasing new materials. Because recycled concrete comes at a lower cost, the overall expenses of the project are reduced. 

 

Summary

Any major construction project will require some sort of concrete demolition and/or removal. To exude max efficiency, having the right tools and equipment is key. Demolition robots, concrete cutters, excavation attachments, and removal tools are just a few of the necessary machines to consider using. However, because these tools can run a hefty price tag, renting can be a better option. A-Core concrete specialists have been at the forefront of concrete work in Utah since 1974.

Demolition Robot Equipment

Machinery has indeed made human life easy. Not only in one aspect, but in nearly every facet. Worldwide urbanization continues to grow in the form of new buildings, changes in infrastructure, and the remodeling of old cities. All this progress is heavily due to machinery. Through the use of machinery, human labor and workforce is significantly reduced. Machines are not only less costly but also more time-efficient.

 

Much of the development you see today is due to one player in machinery, the demolition robot. Demolition robots have played a significant role in establishing tall buildings, placing rooftops, and much more. As these machines continue to aid the industry, their value moving forward is tremendous.

 

Here is what you need to know about demolition robots.

 

What are demolition robots?

Demolition robots are a type of heavy machinery. Their primary is to demolish buildings once it’s time for new development. However, these robots aid in various other purposes too.

 

Demolition robots are widely used in the construction industry for demolishment and evacuation. They are crucial in moving heavy materials from the ground floor to higher floors.

 

Currently, demolition robots occupy 90% of the robotics construction market. These machines are ever-growing in popularity. And as their applications continue to expand, they may even occupy more of the market.

 

 

Advantages of Demolition Robots

Demolition robots are revolutionizing the construction industry. But what makes them so practical?

 

They Come With Tremendous Power

Being a heavy-duty machine, demolition robots have many added advantages. One of the most evident is power. Although the robot’s size is much more compact than its counterparts, its power is much greater. These tools are able to continue forward without interruption or breaks. They can significantly outperform excavators that are five to six times larger.

 

Remote-controlled Operations

Among demolition robots, you can find that there are a variety of types. One of the classes of demolition robots is remote-controlled demolition robots. The remote-controlled aspect of the robot provides an added control to its features. In addition to greater efficiency, they are safer than the manually operated options. Because operators can control them from outside the machine, the risks are lower. They are safe from harmful elements and unforeseen collapses.

 

The Three-Armed System

Most demolition robots are equipped with a three-armed system. On construction sites, some areas are compact and dense, making them hard to access. The three-armed system extends the range of reach of the robot. These robots are able to access anything in a 360-degree range. Previously inaccessible areas are now far more approachable. Additionally, the three arms provide better precision and accuracy for more exact work.

 

Heat Resistant

The evacuation and demolition of buildings takes a large amount of power. With this power comes a lot of heat. As the construction machinery generates this energy, the cylinders inside become hot. This is dangerous to the operator and the engine. Many demolition robots are heat-resistant. This is safer for the operator, the environment, and the cylinders. They keep every component safe and reduce the likelihood of overheating. This also extends the longevity of the demolition robot.

 

Disadvantages of Demolition Robots

Like all things, there are always drawbacks. Though demolition robots can be advantageous, they have their caveats. 

 

Experienced professionals.

Only experienced and trained professionals can operate demolition robots. Meaning, other members of the crew who lack the specialized training are unable to operate it. Having an untrained person handle the robots is both dangerous and damaging. Because of the required extra care and precision, it is easy to misuse. Extra training is an investment. But it’s needed to safely and effectively use a demolition robot.

 

Training

Extra training is an investment. But it’s needed to safely and effectively use a demolition robot. If you plan on using demolition robots, providing training is indispensable. This said, trainings cost money and time. Companies planning on operating demolition robots need to budget for the extra expense.

 

Machine Error

Unlike humans, machines are unable to make cognitive decisions. Their movements are reliant on computer algorithms. While these codes are precise, they are not flawless. Robots can only do the exact job directed by the code. If an unexpected situation occurs, they are not capable to react and adapt as a human would. It is important to recognize that these machines are not without risk.

 

Investment cost

Demolition robots are expensive. There is no way around it. Not every company can bear the upfront investment cost. They average a market cost of around $200,000. The investment cost requires a stronger pipeline of projects for a profitable ROI. However, many construction outfitters offer rentals for much less. If your use for the robot is limited, this is a good option.

 

What factors to consider when choosing demolition robots?

Demolition robots are a considerable investment that should be well researched. Different models are preferable for different jobs. There are several factors you should consider when looking to buy one.

 

Safety codes

Safety codes are necessary for liability purposes. Choose a robot that meets all the required safety codes. Depending on the project, restrictions may vary. Investing in the right machine protects your employees and limits your liability.

 

Affordable Offline Programming Software

Demolition robots come with programmed software. This includes codes for various jobs and functions. Opt for a robot that has only the software programs you need. Often, there are extra offline features included in the software. If these aren’t necessary to your projects, then they only increase the cost.  You want to pay for only what you actually need.

 

Low energy consumption

Consider robots that have low energy consumption and high-value generation. For both environmental and economic purposes, robots with low energy expenditure but high value are ideal. Efficiently designed, slim, and lightweight robots require less energy per value generation. This saves time and money all while increasing productivity.

 

Robot controllable features

Look for robots with features that are beneficial to you and your projects. Most people look for compact size, slim shape, fast processing, and the ability to expand. Expandability is necessary to accommodate extra equipment and features. Ideally, you want to find an option that matches the nature of your projects.

 

Who To Choose?

Here are the top companies which manufacture demolition robots.

 

Husqvarna

Husqvarna is one of the best manufacturers of demolition robots. They make both manually operated demolition robots and remote-controlled demolition robots. Husqvarna is at the forefront of robotic technology. Their robots contain the latest tech, are low weight, and have high power. They boast functional designs fit for a variety of projects. The Husqvarna dxr 310 and Husqvarna dxr 140 are amongst the best robots from the manufacturers.

 

Brokk

Brokk is one of the leading companies in successfully manufacturing demolition robots. Unlike other manufacturers, Brokk builds customized demolition robots in addition to standard models. Their current focus is developing the machine intelligence of the robots. As aforementioned, machines lack the adaptability that humans can provide. Refining the “brain” of these robots is the next step in making them more reactive to unforeseen situations. 

 

 

Bottom Line

Demolition robots are revolutionizing the construction industry. They provide unparalleled help in building demolition. As they continue to be refined, their applications are endless. While they have their nuances, particularly the initial cost, they will become indispensable. Avoid the market price, and consider renting a demolition robot from Rasmussen Equipment.
