Pluggers, originally intended for the extraction of ore miners, today is widely used in construction.At the present time it is impossible to build any object without using a jackhammer.In the construction market, you can find a huge selection of jackhammers various modifications.But when it comes to repair work, the best option - electric jackhammer.This lightweight, easy-to-use tool, characterized by low levels of vibration and noise.Use it faster and easier to make alterations to the premises, the dismantling of various designs, or make the finishing work.

- Features Some models of electric hammers
with an electric jackhammer, you can perform various types of construction works:
- removing old finishesmaterials (plaster, tiles);
- dismantling of brick, concrete, monolithic structures;
- penetration window and door openings, niches and recesses;
- shearing edges;
- loosening frozen ground;
- destruction of foundations, slabs and slabs;
- cutting metal.
The only drawback of this type of tool is dependent on the DC power supply: Supply power and portable power.Yet electric hammer has advantages over air, which is needed for energy-compressor.
Key Features The design of the electric hammer resembles a hammer, differing only in the absence of a mechanism of rotation of the hammer bit.The work is based on the action of the hammer built motor driving the rotor.Special striker strikes were located inside the body of a jackhammer.The striker starts to move as a result of the rotor.During the fast reciprocating movements of the striker is a destruction of the processed material.
Electric hammer is not designed for drilling or cutting the material during rotation - all of its design is aimed at maximum power impact.
main technical characteristics of the electric jackhammer - the energy impact, power and number of strokes per unit time.Based on these values, determined by the maximum allowable density of the material, which will operate a jackhammer electric power electric hammers reaches 1700 W, the number of strokes of up to 2000 per minute, the impact energy - up to 45 J.
on what to look forwhen choosing an electric jackhammer?
If you decide to buy an electric jackhammer worth exploring additional features of this tool.
- possibility of locking the switch in position.This feature provides a convenient long-term operation, saving you from having to hold off while using the tool.
- limit function idle speed will increase the performance of a hammer - in the absence of load system limits engine speed.
- vibration damping system reduces tool vibration, making work more comfortable.
- warning system cable break leads to stop the tool when working in the vicinity of critical paved utilities.
- Dust (sealing system) is used to prevent tool breakage when working in hostile environments.
- greater efficiency will provide the possibility of fixing pin in different positions and electronically adjustable rpm.
- unexpected tool wear will help prevent a system for indicating brush wear.
Electric hammer can be equipped with two types of ammunition.The first type - keyless chuck, providing a quick change of shift working peaks, which increases productivity and simplifies the operator's job.The second type - the hex sockets, which mount the peaks achieved by a special key.
Features Some models of electric hammers
When choosing electric jackhammers important role played by the purpose of their future use.Preferred characteristics of the instrument are determined based on the conditions and the scope of its application.
