Many owners of private houses and summer residents are bound to face the need for repairs in their lives. Someone expands the living space, someone is tired of the arrangement of windows and doors in the house or an old wooden outbuilding, knocked down on nails in a finger of thickness.
To solve these problems, you cannot do with an ordinary tool, you need to buy a jackhammer, which will allow you to crush concrete and brick walls, chop metal reinforcement and loosen rocky soil.
Our article offers you information about what kind of bumpers are, how much this or that model costs and which company is better to buy equipment. The editorial staff of the site "bestx.htgetrid.com/en/", presenting the ranking of the best jackhammers for 2020, hopes to make it easier for you to choose the right model.

The path from pick to bump
When stone caves were the predominant human habitation, then the first signs in history of the use of devices to facilitate the processing of hard rocks appeared. Most likely, these were stone chisels and axes.
For tens of thousands of years, nothing has fundamentally changed in this area of human activity. As the blocks for the construction of pyramids were cut by hand in ancient times, until the end of the 19th century, the technologies of breaking stone, mining coal and salt remained at the level of a hand pick.
The invention of electric motors and internal combustion engines revolutionized this business. The simplicity of converting rotary motion into translational motion with a periodic impact on the pickaxe led to the emergence of mechanical jackhammers, without which it is impossible to imagine neither the construction of roads, nor mining, nor rescue operations after an earthquake.
Types of jackhammers
The main idea of a tool designed for the destruction of hard materials is to periodically move the working equipment, and the working stroke provides an impact load, and the idle stroke returns it to its original position. The simplest drive for such a scheme is converting the rotation of the motor shaft into a reciprocating movement of the bit using a crank mechanism.
Another approach to driving a jackhammer is using compressed air or working fluid pressure. By means of a bypass valve system, the same impulse effect is achieved.
These two drive principles form the basis for the classification of fenders.
Hydraulic
The work of such jackhammers is based on the fact that the working fluid under high pressure enters the system of spools and valves, where it is converted into impulse movement of the bit. To do this, you need to connect two hoses - for supplying and returning fluid. The fluid used is transmission oil, which is pumped to the required pressure in the pumping station.
In parallel with this, there are bumpers in which a hydraulic motor is installed that rotates the rotor due to oil pressure. With the help of a crank mechanism, the piston movement is transmitted to the firing pin.
The field of application of hydraulic breakers is limited by the specifics of the operation.For example, they are indispensable when working underwater, where the electric tool is dangerous, and the pneumatic one interferes with the exhaust air.
Gasoline
These bumpers have an internal combustion engine as a drive and transmit impulse to the firing pin through a crank mechanism with a piston. To increase the hammer power, it is necessary to increase the engine size and install a larger fuel tank.
That is why the petrol fender is larger and heavier. In addition, flammable fuels are dangerous. They cannot be used in confined spaces due to the danger of exhaust gas poisoning.
These disadvantages limit the scope of such a tool. They are used where there is no electricity at all: they are used in emergency situations when dismantling the rubble of collapsed buildings, when it is impossible to supply electricity or compressed air.
Pneumatic
These hammers function in the same way as hydraulic hammers, except that a stream of compressed air is used instead of oil. They are very compact, reliable and safe. They are most widely used in construction work and in mines, in the extraction of minerals and the dismantling of building structures.
They require a compressor to compress the air. The only drawback is the high noise level when the air leaves the case.
Electrical
An electric motor is used as a drive. They have many advantages. Lightweight and compact, they have become widely used in everyday life. Power tool manufacturers offer a variety of models that differ in both power and impact force.
In parallel with the hammer, a hammer drill appeared - a device that combines the impulse effect and drilling. Such a tool is indispensable for making holes in concrete and brick walls.
The disadvantages of electric jackhammers include the risk of sparks forming on the electric motor manifold. This limits their use in conditions of increased fire hazard, especially when gas pipes are released from the walls. Therefore, they are not used in mines, as well as in rescue work on the ruins of houses and industrial buildings.
Demolition hammers characteristics
The main indicator of the effectiveness of a bump stop, along with power, is the impact energy, measured in joules. It varies from 5 to 100 J for different models. The minimum values apply to the removal of old tiles, plaster and dismantling of small structures. Large values allow you to destroy road surfaces, chop rock, and cut metal structures.
The frequency of striker strikes on the working bit determines the ability to work with different materials. The force of the blow is inversely proportional to the frequency. At a lower frequency - more force, which means that you can destroy a harder material.
Taking into account the harmful effect of vibration on humans, all fender structures are equipped with anti-vibration systems.
Traditional fastening of the working bit in the chuck is of three types:
- hex shank HEX;
- SDS-plus - has four slots and is fixed with balls (designed for light bumpers and hammer drills);
- SDS-Max - used for shanks with a diameter greater than 20 mm, has special grooves and is fixed with wedges.
