MTB 25 Inan Makina MTB 25 Specifications & Technical Data (2017—2026)

High Breaking Power

Although, MTB breakers need lower power from the excavator, MTB impact energies are higher than many other breakers. This comes from the excellent design of MTB pistons.

MTB Medium Size Hydraulic Breakers

Hydraulic Breakers are chosen according to carrying capacity of the carrier machines. There are designed 5 sort of MTB models with 650 to 1870 kg weight for 7-29 ton class excavator. There are big size excavators are used at the open mine and quarry, and medium size breakers are not used at these applications. Medium Size MTB Breakers are used for trenching, ditching, excavation, demolition, tunnel construction, underwater application and etc. Medium Size MTBs are given high class performance and easy operation with perfect design, high impact energy, low maintenance cost for you.

MTB Demolition Attachments

MTB Demolition Attachments are useful for primary and secondary concrete demolition. There are different designs for demolition applications. There are technical specifications of primary and secondary demolition attachments.

Adaptable

A range of drive units with different auger diameters and digging teeth means MTAG is available for all types of excavators, and suitable for a wide variety of applications.

Crusher-CRS

The jaw design is suitable for cutting concrete and reinforced concrete structures as a primary demolition. Behind the jaws, there are steel blades to cut iron bars inside the concrete.

Shear-SHR

Shear is available to cut rebar, iron blocks of steel structures (building, road beams etc.), dismantle the ships for recycling and etc. It allows primary demolition of the steel structures quite, fast and safe.

Wear Parts

All round teeth: made of tempered material, bolt-on teeth are suitable for earth and clay. Strong tungsten teeth: tungsten tipped, suitable for medium - rich soil, stony or frozen ground, heavy clay or asphalt.

Rock Drilling Equipment

Rock Drilling Equipments and Spare Parts are used for fast and reliable drilling application that are produced with latest manufacturing technologies for longlife and best quality. There are many different bit design to suitable all kind of rock and ground conditions. Special material is used for bits body and tungsten carbides on the bit have long wearing life. It allows users fast drilling operation and extended life of bits. We can supply all kind of drilling equipments and spare parts.

Grease Pump

MTU grease pump design is different than other standard grease pumps. It is driven by the vibration force of the breaker. It does not work by hydraulic pressure, which is why there is no need for any hydraulic connection. It is sufficient to connect the grease line from the pump to the breaker. This design allows for easy maintenance, provides suitable force, and does not affect breaker operation due to the absence of a hydraulic connection.

Underwater Application

MTB Breakers can be used for underwater applications effectively. However, if water fills the space where the piston strikes the tool, a strong pressure wave occurs, which may damage the breaker. To mitigate this, there is an air line on the breaker that supplies compressed air to the piston impact area. This compressed air helps prevent the adverse effects of water by removing it from the piston impact area.

Renewed Vital Parts

The New Generation MTB's have been developed to increase working life and performance. Some vital parts' design has been modified.

Blank Firing Protection

MTB breakers work without touching the piston to cylinder (steel to steel) on blank firing time. Our MTBs have a bigger volume oil cushion chamber than other brands, which creates a strong hydraulic suspension. Thus, the MTB breaker can be operated without interruption. Other brands use a stop function or variable stroke control. The "Stop function" works by relief control, where the relief valve opens and closes continuously, causing hydraulic oil to heat up. This warmed oil can cause problems with the breaker and excavator components. The "Variable stroke function" is designed with complicated valves on the breaker, and such complicated parts often lead to issues.

Big Volume Accumulator

Hydraulic Accumulator protects the breaker from peak pressure. The hydraulic accumulator doesn't need gas charging for a long time and can be recharged at the job site.

Special Design For Tunneling Application

MTB New Generation "S Series" has a special piston design to increase working life. Superior breaking power and blank firing protection (hydraulic suspension) provide high performance, productivity, and continuous operation without interruption due to the non-stop function for blank firing. Additionally, there is an autogreasing system and tool bushing wiper for continuous lubrication, preventing dust from entering inside the breaker.

Mtb Drifter (DRF Series)

The DRF drifter is designed to drill hard rock by hammering, rotating, and flushing rock part tides, consisting of simple and practical components. The hydraulic drifter is composed of a flushing part, rotation device, and hammering device. High drilling speed is achieved by increasing the efficiency of hammering energy, which extends the life of consumables. An automatic pressure regulator is provided to adjust pressure to meet various rock properties. The DRF drifter is used for drilling holes for explosion preparations in mines and for mounting steel construction on the walls of tunnel constructions.

Piston

The stress coming to impact area has been reduced by getting longer impact area. Also it provides impact transfer to chisel with high efficiency.

Front Head

With new front head design, the stress that is coming to the front head and side rod has been reduced. The area between side rod nut and tool pin has more stress during the operation. The stress has been decreased by increasing the distance between side rod nut - tool pin with NG MTBs. The NG MTBs' front head is more stronger than before.

Side Rod

The New Generation MTB's (NG MTB) side rod length is shorter than before and has mono anti-vibration rubber. Old series have two rubbers before; dust and mud stay between the rubbers. It cause stuck the side rod inside the front head. NG MTBs don't have this problem. Short side rod has less stress than longer side rod. It has been decreased 30% the stress that is coming on the side rod by new front head design. The thread of side rod is formed by high technology method instead of machining.

Thrust Ring/Tool

The thrust ring design has been changed completely. The chisel and thrust ring touching face angle has been changed from 45° to 60° degree. With this design, the touch-face area is much than before and it provides much longer wearing life. The premature area of tool has been designed both before and after recessing has been removed. It could decrease premature breaking of tool at the retaining area after excessive tightening limit of bushing.

Strong Housing

Housing material is a special bending type material, that's why it is strong. Also the welds on housing are reduced and no housing bolts are used. This makes the housing more rigid and stronger.

Strong Buffer Support

The buffer system (side, top and bottom buffers) that is used in MTB breakers, has a special impact and vibration absorbing properties. This protects the breaker and excavator.

C-Type Housing For Marble Mines

The breakers can be used sometimes like a "ripper". This application is never recommended. Otherwise, housing will be damaged. MTB suggests avoiding the use of the hammer like a ripper, but for this kind of application, MTB has developed the "C-Type" housing design if it is not possible to avoid. "C-Type" housing has long life and high quality for marble and heavy duty jobs.
