The jackhammer (bidder) is a tool without which it is difficult to perform dismantling work, make a niche in the walls of concrete and bricks, remove the asphalt coating. Disassemble jackhammers electric, gasoline and pneumatic.

Constructive features of the bombard

Before you choose a jackhammer, you need to study their features in general and a specific model range in particular to stay on one model that meets most fully your needs. All of them are arranged in approximately the same.

This tool cannot be called complicated.

Main elements

• Drive unit;
• batter, operating from the drive and transmitting pulses to the working body;
• a peak that performs devastating work through reciprocating movements of high speed (more than 1 thousand shots per minute).

Types of executive

Depending on which the work is performed, the peak is selected (tip). In various purposes, use the following types:

• pick-Lomik;
• peak shovel;
• chisel;
• tamble.

Pick-Lomik

This species applies if:

• it is necessary to break the soil;
• remove the coating of asphalt;
• remove concrete or brick;
• it is necessary to destroy rocks.

Pick-shovel

Applied at:

• stripping walls from layer plaster;
• if you need to clean with concrete a large area.

Pick-chisel

Used when:

• in the wall you need to arrange a niche or make a hole;
• harvest of reinforcement;
• it is necessary to destroy strongly freezing soil;
• it is required to dismantle the metal structures.

Pick-Trubovka

Lost performance:

• on the seal of the soil;
• when you need to take a seam, a crack in a place where it is not possible to make in the usual way.

Choose electric jackhammer

Electric jackhammer - not cheap tool. There is no clear division on the household and professional models. It will be about how to choose the optimal option, to pay attention to.

Types of electric jackhammers

This tool is manufactured taking into account the tasks that it must perform. Opening position is divided into vertical and horizontal. And by weight, they can be attributed to 3 types:

• weight less than 5 kg are light bumps. Different versatility. Convenient when working on horizontal sites;
• from 5 to 10 kg - medium. With their help, you can perform complex tasks;
• from 10 to 30 kg - concrete, that is, heavy. Indispensable for the work on the foundation, on the simulatory ground. Working position - vertical.

The heavier the jackhammer, the higher its impact energy.

Makita Jackhammer (Makita)

Manufacturer from Japan - Makita manufactures high-quality electrical and benzoinstrument from 1915. Imcorrusive work is ensured by:

• the number of revolutions is supported by an electronic system;
• depending on whether the surface from the way is processed, the speed is automatically selected;
• the cartridge of steel has protection. You can change the nozzles quickly and safely;
• there is a switch regulating frequency;
• the engine located on the chipper, has a high efficiency, due to which a small amount of electricity is consumed;
• the electrical part has two layers of isolation.

Here is an example: convenient electric jackhammer Makita HK0500

• weight - slightly more than 3 kg;
• makes the maximum of 3.5 thousand blows per minute, the minimum - 2 thousand;
• inlet power - 0.55 kW;
• punch with a strength of 2.8 J;
• steel cartridge - SDS-Plus;
• length is less than 0.5 m (46.8 cm);
• cable - 5 m.
• chisel can take 12 positions with a period of 30 degrees.

Bosch jackhammer

Before some question on the topic: Electric jackhammer How to choose the best, not worth it, because they trust the world leader - Bosch. It is surprisingly combined with a high power and a relatively small mass in the jackhammer GSH 11 VC. Ensure yourself:

• the electric motor has a power of 1.7 kW;
• energy hit - 23 J;
• mass - 11 kg;
• it is capable of working for quite a long time at large loads.

Bosch jackhammer weight (Bosch) can be defined by looking at the marking.

Hitachi jackhammer

The largest holding in the world with the central office in Tokyo - Hitachi produces electric and gasoline bumps of Japanese quality. Here is one of the models: Hitachi's jackhammer (Hitachi) H55SA:

Work perfectly both on a large construction and in everyday life. Splits the surface of high hardness. Is different:

• silent work;
• high speed;
• aesthetic species;
• compact;
• excellent technical specifications:
  • Engine - 1140 W;
  • Stroy strength - 16 J;
  • Frequency - 1450 shots for min.;
  • Weight - 9.5 kg.

Jackhammer bison

A bump hammer produces a Russian manufacturer. This is a reliable tool for intensive work. Combines a lightweight design with high impact energy.

Specifications for one of the models - ZZEZ ZM-1500EK:

• engine - 1.5 kW;
• the cartridge is the same as the Japanese models: SDS-Plus;
• per minute performs 1800 shots;
• energy - 16.5 J.

Destroys concrete coatings, brickwork, stone and reinforced concrete structures. Pobets tiles, asphalt, tight soil.

Jackhammer Dewalt.

DeWalt is an American brand.

To have a general idea of \u200b\u200bDewalt's jackhammers, look at the technical characteristics of the D25960K model:

• consumes 1.6 kW;
• frequency - 1.45 thousand shots in min.;
• hex cartridge (2.8 cm);
• hits 35 J;
• operating voltage - 230 V;
• weight - 18.4 kg.

Hilti jackhammer

Hilti is a European manufacturer. An ideal option for heavy and medium-sized works is the TE 706-AVR model.

• Power - 1.2 kW;
• weight - 7.2 kg.

Used:

• when performing openings: both door and windows size larger, Ches 0.2x0.2 m;
• when dismantling the water supply;
• if you need holes for pipes and cable channels.

Jackhammer from the instrumental company Enekor

The jackhammer Eckor is a variety of models designed for the performance of various complexity. Hexagon hex 30 cartridge. Electropneumatic shock mechanism.

Choosing a pneumatic jackhammer

Design

Pneumatic jackhammer design includes:

1. handle;
2. shock absorber;
3. spring;
4. valve;
5. ring for fixation;
6. frame;
7. drummer;
8. buffer spring;
9. peak;
10. nipple.

Compressed air flow over rubber-free hoses.

The principle of operation is similar to the work of an electric jackhammer, only the drive here is pneumatic. Therefore, without a compressor: inpatient or mobile, it cannot function. The pneumatic jackhammers differ by the type of air distribution:

• valve;
• spool.

Divide this tool and by weight:

• from 5 to 7 kg - lungs;
• from 7 to 10 - medium;
• from 10 to 13 kg - heavy.

Criteria for choosing a pneumatic jackhammer:

• reliability;
• ergonomics;
• service features;
• what is offered in the kit.

Dumplings with a gasoline engine

If the engine is installed on the chipper on gasoline, it does not need a compressor nor the source of electricity. Gasoline tank usually accommodates such a fuel volume that a jackhammer can work without shutting down a long time. A gasoline jackhammer has all the functions that are present in electrical and pneumatic dumps.
