Ranking of the best concrete crushers for excavators for 2022

At first glance, it may seem that the demolition of 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 explosives to destroy buildings, but often special equipment with attachments is used.

In our article, we will talk about one of the attachments used for the demolition of buildings - concrete crushers for excavators. Also from the article you will learn:

• about manual dismantling and dismantling with the help of special equipment;
• the main technique that is used for destruction;
• what is a crusher;
• What are the types of crashers.

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. Mechanical demolition.
3. Waste sorting.
4. Crushing construction debris (bricks, reinforced concrete, concrete, etc.).

Manual dismantling is a time-consuming and lengthy process that uses drilling and wall saws, power cutters, joint cutters and other small-scale mechanization devices. Manual dismantling is resorted to if 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 attached equipment is attached - a crusher, which will be discussed in our article.

Building demolition equipment

As already mentioned above, the main device during destruction is a caterpillar excavator. He is involved in many stages of the dismantling of construction sites: from demolition to sorting. Despite multitasking, the main task of the crawler excavator is destruction. Based on the main task, this technique is called a demollator or excavator-destroyer.

There are no single 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 boom length - which allows you to easily reach remote places of buildings;
• work with attachments of large mass;
• add-ons for more efficient work (for example, control and monitoring of disassembly);
• more engine power;
• equipped with a caterpillar chassis with variable track width.

Just a few decades ago, for the demolition of buildings, a huge metal ball (baba) was used, which was oared on a steel cable or chain. A blow to the building was applied 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. For dismantling, various equipment is used with maximum efficiency in work. One such piece of equipment is the crusher.

What is a crusher?

A crusher, also known as a concrete breaker, a 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 for primary work - dismantling of structures, and for secondary work - destruction and grinding of reinforced concrete, concrete, cutting of scrap.

What are crashers

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

1. Crusher - used for the primary demolition of buildings. The maximum compression force is 250 tons, jaw opening is 800-900 mm. The device performs the following functions: dismantling of 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 crushers used for fine crushing of debris from structures.
   Hydraulic shears for metal - the device is used for cutting body parts, spot dismantling of metal structures, grinding recyclable materials and cutting beams and reinforcing joints. Designed for use on mini excavators.
3. Hydraulic shears for concrete - used for the dismantling of asphalt pavements, the dismantling of piles and reinforced concrete structures, the demolition of metal structures and the crushing of concrete.
4. Multiprocessors - used for separation of reinforcement, demolition of structures, crushing debris, destruction of floors and piles, chopping wood, cutting and disassembling metal structures. This is a universal device, the versatility of which is possible due to the maintenance of changing nozzles.
5. Specialized hydraulic shears are characterized by high compression force, which reaches 800 tons. It is intended for floor demolition of buildings, dismantling of load-bearing structures, destruction of interfloor ceilings, cutting of metal structures and grinding of monolithic concrete. An extended range of applications is available thanks to interchangeable nozzles.
