Rating of the best concrete crushers for excavators for 2020

At first glance, it might seem that demolishing buildings is an easy and quick task. Despite the fact that breaking is not building, this operation requires special engineering and technological solutions.

In some cases, it is enough to use an explosive to destroy buildings, but often a special technique with attachments is used.

This article will discuss one of the attachments used for demolition of buildings - concrete crushers for excavators. Also from the article you will learn:

• manual dismantling and dismantling using special equipment;
• the main technique used for destruction;
• what is a crusher;
• what types of crushers are.

Dismantling: manual or using special equipment?

Demolition of buildings can be divided into 4 levels:

1. Preparation of the building by workers using manual class equipment.
2. Mechanized demolition.
3. Waste sorting.
4. Crushing of construction waste (bricks, reinforced concrete, concrete and others).

Manual dismantling is a laborious and time-consuming process in which drilling and wall sawing machines, gas cutters, floor saws and other small-scale mechanization devices are used. Manual dismantling is used when it is necessary to demolish buildings that are located in dense urban areas.

If conditions allow, then to save time and effort, the best option would be to use specialized equipment with attachments. The first place in terms of importance in destructive work is occupied by an excavator, it is to it that attachments are attached - a crusher, which will be discussed in our article.

Building demolition technology

As already mentioned above, the main device for destruction is a crawler excavator. He is involved in many stages of the dismantling of construction projects: from demolition to sorting. Despite the multi-tasking, the main task of the crawler excavator is destruction. Based on the main task, this technique is called a demolator or a demolition excavator.

There are no uniform criteria for distinguishing between a conventional excavator and a destroyer, but the main difference between them is:

• in additional devices for safety - destruction is a dangerous process that requires a maximum security system;
• increased length of the boom - which allows you to easily get to remote places of buildings;
• work with attachments of large mass;
• additions for more efficient operation (for example, control and monitoring of disassembly);
• more engine power;
• equipped with tracked chassis with variable track width.

Just a few decades ago, a huge metal ball (baba) was used to demolish buildings, which is oar on a steel cable or chain. The blow to the building was made by swinging the ball with an arrow. To use such a dangerous method, it was important to have a large space and high professionalism of the operator.

Now the process of destruction does not pose a great danger. Various equipment is used for dismantling with maximum efficiency in work. One of such equipment is a crusher.

What is a crusher?

Crusher, also known as a concrete breaker, processor and hydraulic shears, is a body to which cutting and breaking elements are connected in the form of one or more short "jaws". The elements are driven by hydraulic cylinders. "Jaws" are made of high-strength alloyed alloys, which makes them very strong and durable.

This attachment is used both in primary work - dismantling of structures, and in secondary - destruction and grinding of reinforced concrete, concrete, cutting scrap.

What are the crushers

Crushers, as already written above, are called concrete breakers, processors and hydraulic shears. Despite the fact that "in the people" these names are synonyms, there is still a difference between them. This type of attachment is divided into 5 types:

1. Crusher - used for the initial demolition of buildings. The maximum compressive force is 250 tons, the opening of the jaws is 800-900 mm. The device performs the following functions: dismantling structures (destruction of reinforced concrete, concrete, etc.), transfer of debris, crushing, separation of reinforcement from concrete, biting of reinforcement, destruction of floor beams.
2. Crunchers are a type of crusher used for fine crushing of debris from structures.
   Hydraulic shears for metal - the device is used for cutting body parts, point dismantling of metal structures, crushing recyclable materials and cutting beams and reinforcing joints. Designed for use on mini excavators.
3. Concrete shears - used for demolition of asphalt pavements, demolition of piles and reinforced concrete structures, demolition of metal structures and crushing of concrete.
4. Multiprocessors - used for separating reinforcement, demolishing structures, crushing debris, destroying floors and piles, chopping wood, cutting and dismantling metal structures. It is a versatile device, the versatility of which is possible thanks to the maintenance of nozzle changes.
5. Specialized hydraulic shears are distinguished by high compression force, which reaches 800 tons. Designed for floor demolition of buildings, dismantling of load-bearing structures, destruction of interfloor ceilings, cutting metal structures and grinding monolithic concrete. An extended range of applications is available thanks to interchangeable nozzles.
