Demolition robots
Essentially, demolition robots are mini excavators with special features. They are often used for indoor applications and, as they are remotely controlled, they are the most suitable carrier type for developing demolition jobs that are too dangerous for an operator.
On this machines, an operator compartment is not needed and this allows to build much lower machines and locate components on the upper carriage.
All parts of these machines contribute to the performance and no dead weight is needed, which gives the best power/weight ratio compared to any other carrier type.
The undercarriage is similar to a mini excavator but it is also equipped with outriggers to give more stability. Although rubber tracks are standard on small robots, bigger units are often equipped with steel tracks. The front linkage consists of a 3-section boom that gives a wider operating range and enables the machine to work under low ceilings or other obstacles.
The boom is mounted very low on the central point of the swing gear which gives good lifting force with a light counterweight.
Furthermore, most demolition robots are powered by electricity, as this has some important advantages. It is easy to start, silent, exhaust free, powerful, and it doesn’t need a fuel tank or batteries that may cause problems if the machine rolls over on a jobsite.
However, there also exist in the market robots with gas and diesel engines.
For last, specific attachments for demolition robots can be found in the market.
Material handlers
Material handlers are carriers used for loading and sorting jobs where good lifting force and accurate handling are essential. Usually, they have a powerful hydraulic system.
Light material handlers are sometimes modified wheeled excavators equipped with suitable equipment and wider outriggers to give more stability with heavy loads, although they can also be special machines designed for demolition and recycling.
For their part, heavy material handlers are always special machines with wheeled or crawler undercarriages.
In any case, the cabin may be mounted higher, or it may be hydraulically adjustable horizontally and vertically to give a better view of the container (truck, train, ship, etc.) where the materials are being loaded/unloaded.
These carriers have the benefits of high lifting capacity (big attachments) and precise and powerful hydraulics.
All the attachments that can use with excavators and long front machines can also be used at the material handlers.
