Rating of the best hydraulic breakers for 2024

Humanity has always strived to create universal tools of creation, but rarely when these aspirations were crowned with success. But the creation of universal weapons of destruction succeeded much better. The hydraulic hammer is one such devastating invention dedicated to the service of good.

Classification of hydraulic breakers

It is called a hydraulic hammer because it is driven by the standard hydraulics of the mechanism, and does not require any additional energy sources. It is a quick-detachable attachment for excavators, loaders, pile drivers, manipulators, and other boom construction equipment used for dismantling operations.

The main parameter of the hammer efficiency is the impact force measured in J. Depending on its indicator, the equipment is divided into three categories:

• Small class (from 400 to 1500 J);
• Middle class (from 1500 to 3500 J);
• Heavy class (more than 3500 J).

Small class

Attachments designed for dismantling operations in cramped conditions, and do not require high power applied force.

• the possibility of using in hard-to-reach places;
• compact size, light weight;
• the possibility of using when working indoors;
• the mechanism has two modes of operation: shock and shock - rotational;

• lack of impact power for the production of all types of dismantling works;
• lower performance.

Hydraulic breakers of this class are used for:

• destruction of ice and a layer of frozen soil T = 20 cm;
• dismantling of asphalt pavements;
• destruction of concrete screeds T = up to 30 cm;
• drilling holes in brick and concrete structures;
• ramming and soil compaction.

Hydraulic hammers for driving piles

The principle of operation of this type of hammer lies in the mechanical action on the head of the pile leading to its immersion in the soil.

Adjusting the impact force allows you to select the required power of the recess and to avoid destruction or deformation of the head of the submerged element.

• equipped with a cooling system allowing round-the-clock operation of the mechanism;

• low noise and vibration;
• high performance and ease of use;

• decrease in productivity when the weight of the pile exceeds the weight of the hammer by more than 3 times.

Hydraulic hammers for driving piles

Hydraulic vibrators are designed to compact the soil to the required characteristics by driving piles. In the presence of replaceable nozzles, they successfully cope with reinforced concrete and wooden piles, sheet piles, pile shells, plastic and composite options.

The principle of operation of the mechanism: under the pressure of hydraulic fluid, a group of eccentrics creates vibration and transmits it through the pile holder to the submerged element. The thixotropic properties of the soil change its characteristics in the vertical and horizontal plane of contact with the pile body, reducing the friction force and ensuring the immersion of the pile element under the influence of its own weight and the mass of the vibrator.

• low noise, minimal environmental damage;
• high amplitude of fluctuations allows to speed up the labor-consuming process of work;
• adjustment of the frequency range, allows you to select an individual immersion mode depending on the properties of the soil and material and the shape of the pile;
• the peculiarities of the mechanism allow not only deepening, but also removing the submerged piles.

• not found.

Breaker selection rules

Before choosing a hydraulic hammer, you need to learn the following rules, non-observance of which can lead to premature failure of the mechanism, or emergency during the work.

Hydraulic breaker selection recommendations

• selection by weight.Construction equipment designed for the use of a hydraulic hammer as attachments is of two types: wheeled and tracked. When selecting a hammer for a wheel-mounted mechanism, it is necessary to take into account that its weight should not exceed 10% of the weight of the carrier and be equal to the lifting capacity of the boom at the maximum reach, otherwise the working mechanism may overturn. The calculation formula for a tracked tractor is the same, but the tolerances are more loyal due to better stability and a low center of gravity.
• selection according to the characteristics of the circulation of the working fluid in the hydraulic system of the technical device. The working pressure of the hydraulic fluid of the hammer must correspond to that of the excavator. The volume of the pumped-over oil should not exceed the capacity of the hydraulic system, otherwise the failure of an expensive oil pump cannot be avoided.
• the tasks facing the hydraulic hammer and the conditions in which it will be operated are especially important in cases where the mechanism is supposed to be rented, and the factors listed above are simply not known.
• any task has its own cost, and therefore, in the operation of the mechanism, the cost price is of paramount importance. The last, but very important factor of choice is the price of the hammer.

Hammer attachments

Hydraulic hammers of all categories, in addition to the listed advantages, have one more: replaceable nozzles, which allow significantly expanding the range of work performed and increasing their efficiency.

Types of attachments:

• for destruction;
• for sealing.

Destruction nozzles

They represent a metal rod made of wear-resistant steel. It is used for dismantling, crushing and crushing structures; Depending on the task, they differ in the type of tip: chisel, chisel are subdivided:

Pike, with a conical point

• easy penetration into the material;

• labor-intensive extraction, the possibility of jamming in the rock.

For this reason, nozzle manufacturers have developed new lance models, giving the tip, instead of a cone, the shape of a three or four-sided pyramid. Longitudinal cracks are formed abeam the faces, increasing the destructive effect and minimizing the possibility of jamming.

Chisel

A chisel-shaped tip has proven itself well when splitting individual dimensional fragments, even of a strong mineral. Two perpendicular faces create longitudinal cracks, accelerating rock breaking.

Wedge

When working out and loosening frozen soils, making faces, the nozzle with a wedge tip is most effective.

• high productivity and efficiency in the production of certain types of work.

• inapplicability to other types of work.

Since the lance is the working element of the hydraulic hammer, the surface of the tip is subject to accelerated wear from interaction with dense minerals. Loss of the original configuration leads to a decrease in the efficiency of the mechanism and an increase in the load on the drive. The quality of the material from which the nozzles are made is of paramount importance.

The best manufacturer of replacement nozzles for destruction: Delta is a company that has proven itself for the highest quality of its products. The tips offered by the company are made of high-strength, wear-resistant Hardox steel, produced by the Swedish concern SAAB and have an enviable service life.

Soil compaction nozzles

Soil compaction nozzles are designed and manufactured to give the mechanism the versatility of use, but in the process of operation it turned out that this compaction method is much more effective than those that existed before and allows you to achieve density coefficients inaccessible to other methods.

The hammer compactor allows you to increase and stabilize the bearing capacity of loose, loose soils and quicksands to acceptable values, eliminating the need for removal, replacement and other measures to replace unstable soil layers.

The hydraulic hammer market segment is saturated with manufacturers with various price offers and a range of products. This allows you to pick up attachments for the equipment already in the park, without resorting to expensive purchases.
