Electric jackhammer: description and choice

Today, the electric jackhammer has been widely used in the construction industry. Initially, this tool was intended for mining miners ore. At present it is difficult to imagine the erection of any structure without this adaptation. On the market there are many different models of the instrument, which have significant differences.

However, for carrying out repair work it is best to choose a hammer with an electric breaker. This is the easiest to operate, lightweight tool that features low levels of vibration and noise. It will allow to speed up work on re-planning of premises, faster to dismantle various designs or to execute finishing works.

On the market, these devices are represented by models from well-known manufacturers. The best are the tools from "Makita", "Bosch", "Interskol", "Hitachi", "Metabo" and other companies.

Using electric jackhammer , it is possible to easily remove old finishing materials (tile, plaster), dismantle monolithic, concrete or brick structures. It can be used for punching door and window openings, depressions and niches. The tool will allow to chop the edges, loosen the frozen ground, destroy the old foundation, overlapping or slabs. With it, you can cut metal.

The only drawback that an electrical hammer has an electric hammer is its dependence on current sources. However, a mobile generator can be used to provide power.

By its design, the electric jackhammer is similar to a puncher. The only difference is in the absence of a mechanism that rotates the bit. The operation of the hammer is based on the action of the built-in electric motor, which moves the rotor. Striking is made by a special striker in the tool body. Movement striker occurs as a result of the rotor. The resulting reciprocating motions destroy the material to be treated.

Electric jackhammer is not designed for cutting or drilling material when rotating. All his device is aimed at creating the most powerful blow. The main characteristics of the mechanism, which should pay attention when buying, include the impact energy, power, the number of movements per unit time. These values allow you to determine the maximum permissible material density, with which the tool will cope. For example, the engine power can be 2100 W, the number of strokes to reach 2500 per minute, and the shock energy - 50 Joules.

When choosing a bump stop, you should also look at the availability of additional functions. For example, the ability to lock in the operating position of the switch, which will provide convenience, saving you from holding the button. A function of speed limitation of idle turns will be superfluous. Other useful functions: the presence of vibration damping systems and prevention of cable rupture, dust protection, a system for indexing wear of brushes, the possibility of fixing in different positions of the striker.
