ELECTRIC DEMOLITION HAMMER:
What is an electric demolition hammer and types
Patented in 1894 by Charles King, the first demolition hammer was compressed air and allowed to break down reinforced concrete walls or floors.
Since then, the function of the demolition hammer has not changed, the technical characteristics and the types of models have changed. In fact we can find hydraulic pneumatic hammers, compressed air hammers and finally the electric breakers. The latter are generally dedicated to “minor” demolitions and are perfect for conscious “do-it-yourself” use.
Demolition hammer or drill?
Many electric breakers are supplied with two different chisels, depending on the result to be obtained.
- The demolition chisel is useful for splitting concrete blocks of various kinds.
- The perforating chisel is designed for those who not only want to demolish, but also drill holes.
This puncture-demolition flexibility is essential when, for example, you have to remove tiles in the bathroom or in a kitchen, make grooves or peel off a wall: the electric demolition hammer with a perforating chisel can be perfect for a job finished to the fullest.
On the contrary, if you plan to use the demolition hammer only to break down the walls, it will be better to opt for the demolition chisel.
Electric demolition hammer: components
Contrary to what one might think, the demolition hammer is a mechanical object with quite simple and intuitive operation. The parts that make up a demolition hammer are:
- the body, also known as the hammer, that is the main part of the demolition hammer, composed of a handle, a central block, a transmission motor, a coupling and a diffuser;
- the foil (or chisel), that is the pointed part that allows to proceed with the demolition and that is inserted in the terminal part of the body.
The latest generation demolition hammers offer some additional accessories that make use even easier and definitely safer.
Many companies, in fact, have thought of inserting a handle capable of absorbing vibrations and recognizing idle strokes, so as to lighten the work of the operator and reduce the level of stress for the product itself.
Others, on the other hand, have well thought of incorporating control systems that allow the hammer to be adjusted according to the work to be done, choosing the number of strokes and rpm optimal for each intervention. The problem with a similar system is that it is an electronic addition, which does not always succeed in marrying the mechanical part adequately.
How to choose the best electric breaker
Demolition hammers also stand out for their weight. Traditionally, in fact, we can find on the market demolition hammers called light weights, medium weights and heavyweights. This classification, which is inspired by the world of boxing, refers to the weight of the machine and the possible use of the instrument: if you want to scrape off the walls, for example, you will need a light machine, which you can use all day without too much effort.
On the contrary, if you have to demolish a concrete floor you will need to be able to take advantage of the power of a particularly heavy breaker, in order to make the job faster.
Other criteria to follow for choosing a demolition hammer are surely:
- engine power and stroke,
- the number of strokes per minute,
- the oscillation capacity.
Warning: a higher number of strokes per minute will allow you to complete a faster but less precise job, just as excessive power can be detrimental if you decide to use the demolition hammer to create grooves in a wall, but not destroy concrete blocks.
The advice is, therefore, to think carefully about the purpose of use intended for this tool and to choose accordingly, so as to be able to make an investment that does not disappoint your expectations.
Good standards for the use of demolition hammers
These tools involve certain risks that you need to know well before taking action. For this reason, it is good to follow the rules of conduct also envisaged for specialized technicians, so as to safeguard health and operate safely.
Here are the main guidelines:
- limits the number of vibrations to a minimum, so as not to weigh down the muscular and skeletal system;
- expect frequent stops between one operation and another, so as to relieve the tension in the muscles of the hands and back;
- he wears ear muffs, since the decibels reached by the machine can lead to permanent deafness;
- use protective glasses and masks that can protect eyes and respiratory tract from dust created by demolishing concrete walls and floors.
These are small precautions, some of which are made mandatory by law, which can help you operate in the best way.
