The electric jackhammer is simply indispensable in repair and construction work. He is an indispensable assistant literally in any kind of activity, ranging from removing asphalt coverage and ending with other emergency rescue events.

Choosing a jackhammer

By choosing a tool, you should focus on the type of upcoming work. Accordingly, jackhammers are divided into heavy, medium and lungs. For example, when creating repair activities in the form of redevelopment of the room, wall decoration, etc. Most often you have to work on the elongated hands, so in this case it is best to use lightweight equipment. Its average mass is from 5-6 kg, it provides good performance and does not allow a person to get tired.

Supporting hammer

The mechanism of this type of tool is quite simple. It has a special batcher, functioning inside, which strikes the executive part with a frequency of up to 1500 shots per minute. Thanks to this reciprocal action, the destruction of any building material. The electric jackhammer acts with the help of an electric motor that leads to the operation of the rotor, and in turn, the batter.

Safety:

• alternate the mode of work and rest;
• before starting dismantling work, make sure that you move the movement of the drummer and handle;
• prepare place of work;
• this tool should not be applied at high humidity;
• no need to work on this equipment in an increased fire and explosive situation;
• use personal protective equipment;
• vibrating machinery activities should not exceed 10-15 minutes;
• conduct the change of technological processes.

Types of jackhammers:

• petrol;

• pneumatic;

• electric.

In addition to the fact that this type of tool has a difference in the design, each of them has its own advantages and disadvantages. At the same time, a certain type of equipment is suitable for solving a specific value of tasks.

The main feature of the jackhammer is a strike energy that is measured in kilodzhoules.

Electrical models are divided by weight into several categories:

• heavy (up to 30 kg) - used in a vertical position;
• average (from 7 to 10 kg) - used in vertically to dismantle sufficiently pliable building materials, such as brick, asphalt, etc.;
• light (up to 6 kg) - the tool holds on weight.

In order to avoid the negative impact of monotonous vibration on the human body, modern equipment is equipped with a special system of its valve. However, sometimes it is not enough, therefore even additional vibrations are applied.

The blowing hammer impact energy is determined by the power of the electric motor, the peak is the main contact surface for the tool. For various building materials, various types of peaks are used:

• picks-blades;
• peaks-chisel;
• peaks and Lomiki, etc.

Also for electrical equipment there are a large number of diverse tips:

• paving shoes;
• tamble shoes, etc.

Disadvantages of each type of jackhammer:

• for a pneumatic hammer, a special compressor is required with a compressed air generator, respectively, it is sufficiently large and is not used in small rooms;
• the electric jackhammer has engine sparking, so it can lead to a short circuit;
• the gasoline bump assumes constant refueling and is rather noisy.

Thus, the choice of jackhammes should be made, based on the conditions of work, as well as the type of building material.

Types of pneumatic bumps:

• rotary;
• piston.

Advantages of these types of pneumatic jackhammers:

• no moisture is afraid;
• do not spark.

Disadvantages:

• for the work of piston hammers, a compressor is needed;
• for pneumatic - turbine.

Overview of famous manufacturers of jackhammers:

Electric jackhammer Bosch

This type of chipper is designed to dismantle any surfaces and has an exceptionally shock mode. He perfectly copes with such building materials as concrete, asphalt, stone. Bosch chipping housing is made of high-strength plastic or metal. At the same time, according to the type of shank, they can be divided into several types:

• with SDS-MAX patron;
• with a hexagon (for work in difficult conditions);
• with the SDS-Plus chuck (they are performed the easiest work).

Bosch jackhammer is equipped with chisels and peaks, as well as special electronics, which provides reliable operation and comfortable retention of equipment.

Features of this technique:

• availability of a vibration damping system;
• presence of hinge fastening;
• built-in dustswoman;
• has a high impact force coefficient;
• combines excellent quality performance and available cost.

Makita jackhammer Makita

Advantages of a jackhammer of electric type Makita:

• a large range of products;
• designed for dismantling work of building materials of various density;
• reliable;
• durable;
• has excellent quality and functionality;
• convenient to work;
• all heavy models are equipped with an anti-vibration system;
• has a reliable shock mechanism;
• combines the optimal weight, power and strength of impact.

Views:

• Makita HM 1810 (heavy and most powerful);
• Makita NK 0500 (simpler and easy option);
• Makita HM 1304 (very powerful);
• Makita HM 1202C (characterized by power).

Electric jackhammer intercol

This type of jackhable hammer has a fairly extensive scope of use. It is available both to the usual consumer and highly qualified specialists. The pneumatic type of intercola is ideal for redevelopment and dismantling of various designs, ranging from reinforced concrete and ending with asphalt. With the help of it you can drill a hole in the wall, pierce the opening and pave the strides. The most optimal design of the piston allows you to strike at the end of the working tip.

Advantages:

• able to work for a long time;
• possess increased productivity;
• convenient to use;
• combine the optimal ratio of price-quality;
• technically perfect.
