Excavators with hydraulic hammers are versatile machines used for various tasks, including breaking up rocks and concrete, demolishing structures, and even quarrying.
There are several types of excavators with hydraulic hammers, including crawler excavators, wheeled excavators, and mini excavators.
Crawler excavators are ideal for heavy-duty tasks due to their stability and maneuverability.
They come in various sizes, ranging from 10 to 100 tons, and are often used in construction and mining applications.
Wheeled excavators, on the other hand, are more agile and suitable for tasks that require frequent movement, such as demolition and quarrying.
Their smaller size and lower weight make them easier to transport and set up.
Mini excavators are compact and lightweight, making them perfect for small-scale projects, such as landscaping and excavation in tight spaces.
They are often used in urban areas where space is limited.

The hydraulic breaker's weight is around 3200 kg, making it a significant addition to the excavator. The height of the breaker with a standard tool is 2800 mm, while without the tool it's 2100 mm. The breaker's max breadth is 650 mm.
Here are some key features of hydraulic breakers:
The IMI 140 R hydraulic breaker is suitable for excavators with a carrier weight of 19 to 25 tons, making it a lighter option compared to the IMI 320 T.
Innovation Triggered by Multiple Factors
The hydraulic excavator becoming the main tool on most construction sites was a key factor in triggering innovation.
This shift in equipment usage led to a surge in the development of new attachments and assemblies.
The universal applicability of the hydraulic drive system made it an ideal choice for various applications.
Rapid replacement of implements was also a significant factor, allowing for quick adaptation to changing project needs.
The need to reduce manual work and increase machine utilization drove the creation of more efficient equipment.
Energy-saving and environmental requirements further pushed the development of innovative solutions.
Here are some examples of assemblies developed to meet these demands:
- Pile driving equipment
- Plow lowering and pulling devices
- Deep compaction assemblies
Description
Hydraulic breakers are an essential tool for demolition and excavation work, and understanding their features can help you choose the right one for the job. The IMI 320 T and IMI 140 R are two popular models that offer impressive performance.
The carrier weight of the IMI 320 T ranges from 35 to 50 tons, while the IMI 140 R has a carrier weight between 19 and 25 tons. This difference in weight affects the overall stability and maneuverability of the breaker.
The weight of the IMI 320 T is 3200 kg, whereas the IMI 140 R weighs 1400 kg. This significant weight difference is essential to consider when transporting and storing the breaker.
The height of the IMI 320 T with a standard tool is 2800 mm, while without the tool, it measures 2100 mm. The IMI 140 R has a height of 2270 mm with a standard tool and 1720 mm without.
The maximum breadth of the IMI 320 T is 650 mm, and the chisel diameter is 155 mm. The IMI 140 R has a maximum breadth of 580 mm and a chisel diameter of 120 mm.
Here are the key features of the IMI 320 T and IMI 140 R in a comparison table:
The required oil supply for the IMI 320 T is between 200 and 250 l/min, while the IMI 140 R requires 130 to 190 l/min. The oil pressure adjusted to the hammer for the IMI 320 T is 160 to 190 bar, and for the IMI 140 R, it's 120 to 160 bar.

Self Lubricating System
The self lubricating system is a game-changer for customers who want to minimize maintenance and downtime.
This system requires no additional installation on the excavator, making it a convenient option for those who want to get up and running quickly.
It's placed directly on the hydraulic breaker and works thanks to the vibration and blows of the hydraulic breaker itself, a clever use of the breaker's own energy.
The company provides a number of special versions of the same models, all customizable, which means you can get a system that fits your specific needs and preferences.
Thanks to flexibility and versatility, you can have a self lubricating system that's tailored to your unique situation.
Excavator Hammer
Excavator hammers are an essential tool for any construction site, and understanding their features can make a big difference in getting the job done efficiently.
The weight of excavator hammers can vary greatly, ranging from 1400 kg for the IMI 140 R to 3200 kg for the IMI 320 T.
The height of excavator hammers is also an important consideration, with the IMI 320 T standing at 2800 mm with the standard tool attached.
Hydraulic breakers, like the IMI 320 T, require a significant amount of oil supply to operate, typically between 200-250 l/min.
The IMI Hydraulic Breakers can be provided with a special self-lubricating system that requires no additional installation on the excavator.
The inner diameter of the IN and OUT hoses for the IMI 320 T is 32 mm, while for the IMI 140 R it is 25 mm.
The IMI 170 M and IMI 121 M hydraulic hammers are designed for excavators weighing between 20-30 tons.
The IMI 320 T has a chisel diameter of 155 mm, while the IMI 140 R has a chisel diameter of 120 mm.
Here's a comparison of the energy per blow for different hydraulic breakers:
The maximum back pressure for the IMI 320 T is 15 bar, while for the IMI 140 R it is 12 bar.
Hydraulic breakers are a better option than pneumatic hammers due to their increased utilization of excavators and decreased human workforce.
The IMI Hydraulic Breakers can be classified into hydromechanical, hydropneumatic, and purely hydraulic hammers based on their mechanism.
Box Silenced Rock
The Box Silenced Rock breaker is a game-changer for any excavation project. It's essentially a hydraulic hammer that uses the power system of the basic machine, replacing the pneumatic demolition hammer that was previously mounted on the excavator.
The hydraulic hammer is a more efficient and effective option, allowing for smoother and more precise work. This is especially important when working in tight spaces or with delicate materials.
One of the key benefits of the Box Silenced Rock breaker is its ability to operate in a variety of environments. As we saw earlier, it can work with the power system of the basic machine, making it a versatile and reliable choice.
