Pain points of overseas market customers: Noise limitations and multifunctional demands
In developed regions such as Europe, North America, and Australia, projects like urban construction, indoor demolition, and old road renovation are subject to strict noise regulations. Complaints from residents, night construction bans, and environmental fines have become major pain points for contractors. At the same time, many work scenarios require breaker hammers to operate in irregular spaces , such as stairwells and pipe trenches, demanding that the equipment be capable of breaking in multiple directions, such as horizontally and upwards. Additionally, different brands of excavators such as Komatsu, Caterpillar, Hitachi, etc. require quick and nondestructive installation of attachments. To address these needs, METDEEM has launched the box type breaker Series, focusing on low-noise, high adaptability, and multi-angle operation, to help customers comply with regulations and complete projects efficiently.
Core Technology of the Product: Fully Enclosed Silent Design
- Special Enclosures and Shock Absorption System
The METDEEM silent type impactor is equipped with a fully enclosed housing, which is composed of high strength steel plates and internal super durable rubber blocks. The rubber blocks not only absorb the vibrations caused by the piston impact but also block the path of noise transmission. Compared to ordinary impactors, the working noise can be reduced by 15-20 decibels. The measured value is as low as 85 decibels, meeting the requirements for construction in urban areas during both day and night.
- Dual Protection from Both Inside and Outside
The shock absorbing rubber blocks also serve as a buffer, preventing the internal mechanism and the casing from colliding and wearing out due to long term vibration. This significantly extends the lifespan of the hammer body, reduces the frequency of maintenance, and saves operating costs for customers.
Flexible Operation: Multi-angle Fragmentation and Straight Installation
Comprehensive Fragmentation Capability
Traditional breakers are mostly used for downward vertical crushing. The interruttore tipo scatola body design of METDEEM allows for multi-angle and multi-position operation, including vertical downward breaking, horizontal wall demolition, and upward ceiling removal. It is particularly suitable for:
- Removing indoor stairs
- Layerby layer demolition of partition walls
- Horizontal excavation of pipe trenches
- Breaking old house ceilings or floor slabs
Positioned in a straight line with the forearm, the operation becomes simpler.
After installation, the whole breaker can remain aligned with the excavator boom and stick for improved visibility and control, providing a wide field of vision. The operator can achieve more precise positioning in confined spaces, reducing the risk of accidental contact with surrounding structures.
Wide Compatibility: Covers excavators ranging from 0.8 tons to 70 tons
The METDEEM box type breaker offers multiple models ranging from small to super-large, and can be seamlessly compatible with the leading global excavator brands:
| Bulldozer tonnage | Examples of compatible models | Recommended interruttore tipo scatola models | Main application scenarios |
| 0.8- 2.5 tons | Kubota, Yanmar, Sany micro excavators | DM40 box type | Indoor small partitions, pipe slotting |
| 3-6 tons | Komatsu PC35, Hitachi ZX40 | DM53/68 box type | Old house interior demolition |
| 7-14 tons | Caterpillar 305.5, XCMG 75 | DM75/75A box type | Staircase, floor crushing |
| 15-25 tons | Liugong 915, SK20 | DM100/125 box type | Multistory building demolition |
| 30-50 tons | Hitachi ZX350, Caterpillar 336 | DM155/175 box type | Old road renovation, bridge pier demolition |
| 55-70 tons | New Holland, large mining models | DM195/210 box type | Large volume concrete crushing |
All adapters come with standard installation brackets, and there is no major structural modification required; only standard mounting bracket and hydraulic matching are needed. They can be installed and used immediately.
Typical Application Scenarios: Indoor and Urban Demolition
- Interior Demolition-Staircases, Partition Walls, Pipe Installation
The low noise feature of the silent type breaker hammer enables it to be used for night or weekend construction in buildings with people present, such as hospitals, schools, and office buildings. The breaker hammer can operate laterally and precisely dismantle walls without damaging the floor.
- Renovation of Old Buildings and Pavement
In the renovation project of the old European city, excavators equipped with box type breakers break the structure layer by layer from the top, while spraying water to suppress dust. Compared with hydraulic shears or expansion agents, the efficiency is increased by more than 50%, and there is improved dust suppression and reduced airborne particulate emissions.
- Urban Road Renovation
Nighttime road construction is extremely sensitive to noise. The METDEEM box type breaker, together with the sound insulation cover and shock absorption system, can control the impact noise within the legal limit, avoiding complaints from residents and fines.
Installation & Maintenance
- Standard quick installation with hydraulic coupler
- Daily inspection of rubber damping system
- Lubrication system maintenance intervals
Conclusione
Compared to traditional pneumatic picks, hydraulic splitting machines or expansion agents, the combination of excavators and METDEEM box type breaker has the following advantages: faster construction speed, which can crush 10-20 cubic meters of concrete per hour; higher personnel safety, as it can be remotely controlled; lower overall cost, no need for additional noise reduction barriers. For foreign contractors who prioritize compliance, efficiency and low complaints, this is currently the most reliable solution.

Domande frequenti
Q: How much can the noise of the METDEEM box type breaker be reduced?
A: Compared to ordinary crushers of the same model, it can reduce the noise by 1520 decibels. The actual measured working noise is approximately 8085 decibels, which is close to the limit for nighttime construction in cities.
Q: Does the silent casing affect heat dissipation?
A: No. The outer shell is designed with directional ventilation ports, and the reasonable layout of the internal rubber blocks ensures that the temperature rise of the hydraulic oil remains within the normal range.
Q: Can it be installed on nonpreferred brand excavators?
Answer: Yes. We offer custom installation brackets. All you need to provide is the size of the excavator’s small arm pin and the hydraulic parameters, and they will be compatible with any brand.
