Impact of a hydraulic hammer on the base machine

A hydraulic hammer is a multifunctional replaceable device that is equipped with excavators and hydraulic machines, including loaders, manipulators and other special equipment. Compared to other types of working units, hydraulic systems are considered active equipment that dynamically affects special equipment. Controlling the pressing force can be difficult for the operator, so the machine is suspended and supported by the hammer itself. This allows the lift-off height to be reduced as the unit deepens into the surface being treated.

Features of the design and operation of hydraulic hammers

Hydraulic hammers are used for:

• destruction of reinforced concrete buildings and concrete structures;
• loosening rocks and frozen soil;
• digging up underground communications, asphalt;
• driving piles;
• compaction of loose soil.

During long-term operation and high loads, working elements and components are subject to accelerated wear. The most reliable units, including Case, can fail or work incorrectly. If you need to change parts for Case equipment, it is advisable to place an order at the Snabavto store, since this company supplies original and high-quality spare parts.

The hydraulic hammer design includes the following components:

1. Pike . This tool is universal, made in the form of a metal rod equipped with grooves for fixing in the motor axle box. The impact component of the unit acts on the upper end, and the lower part interacts with the destructible surface (its shape can change - a rounded cone, a flat end, a pyramid with edges).
2. Klin . This unit is recommended for use if it is required that the cracks on the surface being treated extend away from its blades. The latter can be placed lengthwise or across.
3. Chisel . This tool belongs to the wedge category and is equipped with a sharpening angle of more than 30 degrees. The use of a chisel and a wedge is important for destroying road surfaces or loosening soils.
4. Tamping part . Intended for soil compaction.
5. Branch pipes, tongues and caps for piles.

Some manufacturers are trying to reduce the level of dynamic force on the working unit. To achieve this, the breaker part of the hydraulic hammer is installed in a special protective casing with the possibility of slight movement when the shock absorbers are activated. The latter are made in the form of springs, plastic or rubberized modules. The use of such devices makes it possible to reduce the force on special equipment if the deformation of the unit is no more than the amount of insertion of the unit per force. But since the energy intensity value is low, equipment with suspended wheels will not be protected if the working material is destroyed.

Excavators with hydraulic hammer attachment

Excavators with a hydraulic hammer attachment are an extremely popular type of construction equipment today. With their help, construction and repair teams open up asphalt pavements, dismantle reinforced concrete structures and are able to perform other equally complex tasks.

Today, almost all models of both foreign and domestic excavators have a hydraulic hammer attachment. Some models come with it, while other excavators require it to be purchased separately.

In this article, we will talk about the benefits of a hydraulic hammer for an excavator, what its main functions are, and which of these products are the best of their kind.

Main functions of a hydraulic hammer

The first thing that should be noted when talking about a hydraulic hammer is that it can significantly expand the capabilities of an excavator. There is a separate article on our website dedicated to this issue. Nevertheless, we believe that it would not be superfluous to list them again.

As you can see, a hydraulic hammer has a lot of useful functions that can significantly expand the capabilities of an excavator. It should be noted that this attachment can be installed on both domestic and foreign-made cars. Many models of such brands as JCB, Bobcat, JAC, SDLG are sold with already equipped hydraulic hammers. The same applies to some representatives of the domestic automobile industry. As for the rest of the products, almost all of them (with the possible exception of some representatives of the economy class), although they do not have this attachment included, have the ability to install it. Thus, the hydraulic hammer can be installed on almost all types of backhoe loaders.

Which hammers are the best?

By type, hydraulic hammers are divided into large, medium and small. Large units are designed to work with rocks and frozen soils. Sometimes they are used to dismantle large buildings. As a rule, these devices are installed on special construction equipment or mining excavators, which are large in size and weight. Therefore, for most owners of construction and repair companies they are of no interest.

The situation is completely different with hammers of medium and small sizes. They are most often used when installing a pile foundation for a house, destroying road surfaces, compacting soils and destroying old reinforced concrete structures. These hammers come in open and closed types. The so-called open ones can only be used in the fresh air (under normal construction conditions), while closed-type devices, due to their tightness, can be used even under water without harm to the unit itself.

The most popular and high-quality hydraulic hammers of small and medium sizes are representatives of the following brands:

• Delta
• JCB
• Hammer
• Doosan
• Soosan
• Bobcat

A distinctive feature of hydraulic hammers of this type is that they are suitable for most current excavators, both domestic and foreign. This means that even if the main construction machine is replaced or fails, you can easily find further use for the attachment you purchased.

Conclusion

An attachment in the form of a hydraulic hammer for an excavator can significantly expand the functionality of this device. With the help of this cunning contraption, a construction machine can, in addition to its main function - carrying out loading work, more efficiently dismantle buildings, carry out excavation work and perform other complex repair tasks. In general, the purchase of such an attachment will be an extremely useful investment for the owner of a construction machine, even if such an attachment is not needed at this stage of its activity. After all, no one knows for sure when exactly such a unit may come in handy during construction work.

Features of hydraulic hammer selection

When selecting a hammer, you need to consider the following parameters:

1. Weight of special equipment . The mass of the working unit should be about 10% of the entire machine, but not more than a fully filled bucket. Lightweight hammers are convenient for transporting and moving equipment; this ensures less serious loads on the machine when pointing at a surface for crushing. However, with a large hydraulic hammer mass, the impact energy and productivity will be higher, and the pressing force will be lower.
2. Oil consumption . This value must correspond to the power of the hydraulic pump of the equipment that supplies the pressure component of the hammer. If the pump is powerful, pressure surges may occur during operation of the machine, which will negatively affect the service life of not only the hammer, but also the working components of the excavator. If performance is low, the unit will function unstably.
3. Operating pressure of the device . This parameter must correspond to the compression of the pump. If this value for a pumping device is 10–15% higher, then a special valve is provided in the hydraulic hammer to limit this parameter. If you do not use it, the studs that tighten the housing or the screws that secure the hydraulic distribution unit may break.
4. The technical performance of the unit, which is determined by its power . This parameter is calculated taking into account the energy and frequency of impacts on the working surface. When the strength of the plane being destroyed is high, the impact force affects the performance.
5. Ease of maintenance and repairability . The easier it is to access lubrication points and connections, the simpler the process of replacing units and components will be. Some hammer models are equipped with automatic shank processing systems, which greatly simplifies the maintenance procedure.

Also, when purchasing, it is recommended to pay attention to vibration and external noise indicators that affect the equipment.
