How to work with a jack of a hammer correctly. How to choose a jack of a hammer – power or speed?

Electric jack hammer. the principles of the chipping hammer

Some people think that it was the pneumatic and chip hammer that was the first step in the development of fucking tools, but the real electric chipper were first invented. However, using them in the most relevant direction at that time-mining-was quite dangerous, due to the high risks of ignition from sparks arising inside the unit. Therefore, when pneumatic hammers arose, they for a long time replaced all competitors to the side. Today the situation takes other turns.

Most users are much more important than mobility is not convenience, but they work with hammers in rooms far from ignition risks, or even outside the room. The builders were not utilities began to actively master an electric jack of a hammer, since such a fucking tool works from pulses of the electric motor, which drives the battleship. Dependence on power sources in the premises where repairs is carried out is usually almost invisible, therefore, among the repairmen, it is electric models that use the greatest love, because they are not relatively inexpensive, they are not able to cope with the assigned tasks.

The gasoline chipper in front of electric non.pneumatic tools has a significant one that play slots. it is not tied to source of energy. However, in his arsenal, of course, other shortcomings are not a noise level, not considerable fuel consumption, not toxic exhausts. Therefore, in the room this is not necessary to work, or it is remarkably ventilated. A pneumatic fucking tool is the most reliable not safe among chipsters. He does not spark, is not afraid of moisture, does not need fuel (except for the air of the air), does not pollute the air with exhausts.

The only negative. it is attached to the compressor, which pumps air under pressure. For repairmen, buying such a tool makes sense only when the compressor is already available.

When working with a chipping hammer, you must use

Multifunctional features and safety rules at one time of work with a jackhammer

The text of the article carefully describes the rules of work with a jack of a hammer, according to safety precautions. The main functions and ability of the tool are indicated. Contains information about the functions of the tool and its features of use, respectively, with the regulations of work.

Multifunctional features

It differs in multifunctionality, is used to a greater extent in road repair work and the construction sphere. An indispensable gadget when dismantling concrete, brick and metal structures, with loosening of asphalt concrete coatings and freezing soil.

The unit is characterized by the highest power and performance. Its power is determined by the number of blows produced by the inventory in one minute.

The main executive body of the instrument is the peak, which is driven by the boiler.

The peak under the mechanical influence of the box makes reciprocating movements, and therefore which is deformation and complete destruction of the working surface

Safety precautions during work with a jack of a hammer

Due to the power of vibration and gross energy, which the jack of chipping produces, the worker must observe safety precautions using this tool. The indispensable use of protective equipment is required. Safety measures are justified by subsequent rules:

  • Work with the use of a chipping hammer should be done only after passing special training and preparation.
  • The working tool needs to be checked for integrity and its serviceability before proceeding to use. Make a painstaking inspection of the tights of the screws and the assessment of the reliability of tickling fastening. If the tool has not been used for a long time, you need to let it work for a couple of minutes idle.
  • It is forbidden to do any work using the tool without using special protective equipment. The operator is expected in a helmet and a protective suit, the continuation of which is anti.vibration mittens and special protective shoes. Incontrolled protective glasses, bears and respirator.
  • In good condition, the chipper should be firmly held with both hands. Exclusively if necessary, create light pressure on the working surface with an inventory.
  • The chipper is recommended to be immersed in the processed material at right angles. It is dangerous to crush the working surface with a junk hammer, almost always incorrect work leads to severe injuries.

Let’s tell you about the work with a jack of a hammer

, about some fundamental properties and safety precautions.

  • The introduction of an electronic chipper during the processing of a whole and solid piece of material should be carried out taking into account special equipment. When crushing whole stiff stone, processing should start with the 1st edge and smoothly lead to the end along the strip of chips. If the working peak of the jack of the chip is stuck in the material, it should be extracted with a light rolling of the tool.
  • At the end of the work, you need to release the inclusion button and press the chipper to the working surface to the efficient version of the stop. To avoid burns and injuries, it is forbidden to touch the working surfaces.
  • It is strictly forbidden to send a working unit in a person who is nearby.
  • It is not recommended to use the tool without load or in the role of scrap in sleep mode.
  • It is forbidden to use the tool for more than 6 hours. The best operating mode is 1 hour of work and 20 minutes of rest.

Electronic jack hammer and peak varieties

For small volumes of work, it is more convenient and profitable to use electronic chips. Electronic chipping hammers do not create the highest vibrational energy, heavy noise and dustiness.

You will like an electronic tool more equipped with different types of peak. Any peak has its own professionalism for a certain task.

  • PIKA-LOMIC. This type of peak is designed to dismantle brick, concrete, asphalt coatings. Just cooles with loosening of frozen soil and crushing rocks.
  • Lopatka peak. Used to align the edge of the asphalt surfaces.
  • Chisel. It is used to a greater extent for cutting, crushing and breaking through any material.

The weight and dimensions of the electronic chipper are of particular importance. Lightweight chips up to 6 kg are used to perform work on decoration. Comfortable in the process of applying while working at altitude.

Jumpers weighing up to 10 kg are used to crush the horizontal working surface. Evebidly used for cutting scale and punching horizontal concrete surfaces.

Heavy chipper up to 30 kg is used to a greater extent to break through and crushing soil and foundation surfaces.

During operation, the chipper should be followed by our client remains safety requirements. The implementation of the above rules will allow to avoid the early failure of the tool and injuries when performing work.

Attention! In working condition, the tool should only be kept by the isolated handles. If a piking of electrical wiring occurs, isolated handles will protect the worker from a shock blow.

  • The use of an electric chipper in the processing of a whole and solid piece of material should be carried out taking into account special equipment. With the crushing of a monolithic stone of solid breed, processing must start from one edge and smoothly lead to the end along the line of the chip. If the working peak of the jack of the chip is stuck in the material, it should be extracted with a light rolling of the tool.
  • At the end of the work, you need to release the turning button and press the chipper to the working surface until a complete stop. In order to avoid burns and injuries, it is forbidden to touch the working surfaces.
  • It is strictly forbidden to send a working unit in a person who is nearby.
  • It is not recommended to use the tool without load or as scrap in sleep mode.
  • It is forbidden to use the tool for more than 6 hours. The optimal operating mode is 1 hour of work and 20 minutes of rest.

How to work with a jack of a hammer

Jackhammer. A tool that works in shock mode in the most difficult operating conditions. That is why the working properties of this tool determine the specifics of working with it.

Before starting work with shock equipment, you should adhere to a simple rule. keep the workplace clean and dry. Extraneous objects, including unnecessary equipment, should be removed. If you hammer the walls or drill deep holes in them, then you should first check them with a hidden wiring detector so that you suddenly do not hit the current. Further, when working in places with a large cluster of people, enclose the working area from the entrance of unauthorized persons so that they do not be close to a working tool. One of the most important rules that should be observed. This is a reading of the instrumentation for the tool, it indicates the main characteristics of the jackhammer and the rules for working with it. This will protect the tool from breakdowns when improper operation, and you. From injuries.

Take care of the equipment. The operator’s clothes should be dense and close the body as much as possible to protect it from sparks, fragments of concrete or brick. Also, we should not forget about soundproofing headphones, gloves and glasses. If the working area is very dusty, then the respiratory system will protect the respirator well.

Preparation of a jack of a hammer for work

The tool itself, like the workplace, requires careful preparation. First, inspect it for external damage, whether all nodes and equipment are reliably tightened. Particular attention should be paid to an electric wire so that he does not have strong bends or breaks. Ideally, the voltage of the mains must be checked by a multimeter to make sure that it corresponds to the voltage for which the hammer is designed. With unstable voltage, use a stabilizer, it will avoid a tool breakdown during jumps in the mains. Following the rules for preparing a hammer for work allows not only to be dismantled with its help, but also to prevent premature breakdown of the unit. It should be borne in mind that if you work with a pneumatic tool, then the compressor should have higher power and pressure pressure than the characteristics of the chipping hammer. Thanks to this, you exclude interruptions in the operation of equipment due to power loss.

As for equipment, always make sure that the equipment cartridge is clean. The chisel is selected by the type of shank and the size of the hole in the hammer.

First of all, the chipping hammer requires regular lubrication, while the new equipment is generally lubricated several times per shift. With constant use, the amount of lubricant decreases to a couple times per working day.

Next, note that the handle and the shock mechanism must move freely, t.You will have to work continuously for a long time.

If you work with an electric tool, then, accordingly, it cannot be used with high humidity or in the open air. He can shorten, hit you with an electric shock and break.

If you remove the old asphalt coating or getting freezing the ground, then work only with a hammer that has high power rates. And vice versa, you should not remove the tile in the bathroom for mining to mining minerals without adjusting the revolutions. Lose both the jackpot and walls in the bathroom.

Do not make a lot of effort during work, otherwise the equipment with the motor will suffer. By the way, immediately after using the unit, let the equipment cool down so as not to get a burn. T.The state of accessories to equipment directly affects the efficiency of the chipping hammer, make sure that they are always well sharpened (for example, flat chisels) and are stored in a dry place processed with a special composition against rust. The equipment should also be lubricated before operation, in particular, this applies to cases when you hammer the hole with a drill.

While working with an electric hammer, follow the electric wire so that it does not fall under the cutting part or does not spin around your foot. Also look so that he is not damaged by the fragments, and do not pull for it to pull out the fork.

According to professional builders with rich experience, an electric tool for definition cannot be more powerful than pneumatic. However, this model fully refutes this statement. We present you a fairly powerful device in which the force of the blow can reach 65 J. this is a rather serious indicator. The amount of electricity consumed is not very large: approximately 1.7 kW/h.

However, before buying, it should be noted that the developers could hardly achieve such power without increasing the overall size and mass of the tool: the jackhammer weighs almost 25 kg. Because of this, without appropriate physical training, it will be quite problematic to work with it, especially since the electric motor vibrates greatly. The device will easily destroy even a very thick partition made of reinforced concrete.

Device and work of a hammer

7.one. A hammer (Figure 1) is a pneumatic pneumatic shock machine with valve air distribution, which works under the influence of compressed air. The hammer consists of an air distribution-attendant mechanism, a handle with a starting device assembled in it and a peel-sput.

7.2. The air distribution and gear mechanism consists of a barrel 2 with a box, jumper, drummer 13, valve box, valve 10, pin 8, saddles 6 and covers 7 pressed into the barrel.

The air distribution and general mechanism carries out: a) the inlet air in the cylinder of the barrel alternately into the direct and reverse stroke of the drummer and the release of the exhaust air into the atmosphere; b) converts the energy of compressed air into a mechanical operation of a moving drummer.

7.3. The starting device consists of a 3, intermediate link 1, plugs, valves, springs 11, nipple 17, a rug nut 18.

7.4. To prevent the self.adaptation of the threaded connection of the barrel and the link, when combining the holes of the barrel with the slots of the intermediate link, the latch is installed.

7.5. Valve cover 7 serves to press the air distribution unit to the trunk end.

7.6. Joining the sleeve supplying air to the hammer is carried out using nipple 17 and the united nut 18.

7.7. To keep the peak from falling on the hammer trunk, the end spring 16 is screwed up, while a rubber sleeve 20 is installed between the barrel and the end spring on the tool.

Depending on the working conditions in the hammer, a peak, shoulder blade, ax or other tool with the required design of the working end may be used. The dimensions of the shank are indicated in Figure 2.

7.eight. The hammer is launched by pressing the handle. The force of pressing when turning on should overcome the resistance of the spring and valve, supported by compressed air. To start the hammer, it is necessary to apply an effort of 68.6–97.6 N depending on air pressure. The hammer is turned off automatically when removing the effort from the handle. The handle of the hammer is made of aluminum casting, the thermal conductivity coefficient of which is 0.4 W/(M-K) and has a surface roughness of 0.8 mm.

7.nine. The hammer works as follows: when you press the handle, the valve moves down and opens a hole communicating with the ring chamber of the valve distribution. With the help of valve distribution, drummer and trunk, compressed air is supplied alternately to chambers, direct and reverse passage, thereby forcing it to make reciprocating movements. Thus, the workflow of the hammer does not fundamentally differ from the working process of any hammer with valve distribution.

Features of the work of hydraulic chipsters

Hydraulic aggregates in design are similar to pneumatic, only the oil pressure works at the expense.

A special distributor cyclically changes the direction of oil coming from the oil pump, thereby acting the working nodes of the chipper. The main structural elements of such chips are a piston with a boy and a plunger.

work, jack, hammer, power

In order not to delve into all the details, we describe the main stages of the work of the hydraulic chipper:

  • The oil under pressure is supplied to the working chamber, where it affects the piston.
  • Then the piston creates the pressure of the oil in the next chamber and affects the bat, which hits the nozzle recorded in the cartridge.
  • The fighting moves back due to the change in the direction of the movement of the oil.

Details of a hydraulic shock tool are not warming in the course of work, thanks to this, they are operated longer.

What is vibrational disease?

Due to the prolonged exposure of vibration (more than a few hours a day), nerves, vessels and joints of the hands are damaged. This leads to the fact that a person feels numbness, tingling in his fingers, such sensations interfere with sleep, fingers often freeze and warming is accompanied by redness and pain, it becomes difficult to take small objects (for example, turn the pages, fasten the buttons), the hands do not have the same strength. Such damage is irreversible. Someone arose after a few months of working with vibrating tools, for someone-in a few years.

Transferring tingling and numbness is not a vibrational disease yet, but its harbinger, and you need to take measures. First of all, try to reduce the time of work with such a tool or use the one that has protection against the transfer of vibration. You need to take 10-minute breaks after working with the tool for an hour. It is also better not to use vibrating devices where you can do without them. If the tool has a blade, it is important that it be sharp: then the vibration will affect your hands less time. Remember: taking care of your health is a direct duty of the employer.
