With the continuous advancement of technology, the use of mechanical equipment to replace human labor has become an inevitable trend in global infrastructure construction. METDEEM Original Manufacture Factory, a wellknown manufacturer from China, focuses on researching and producing various mechanical accessories, contributing to global infrastructure development. This article will quickly introduce the core value and practical applications of excavator accessories.
What are the attachments for excavators
El adjuntos of excavators are various functional devices installed at the end of the small arm of the excavator, used to perform specific operations such as digging, crushing, shearing, grasping, compacting, piling, etc. The main products of METDEEM include: quick coulpers, compactors, pile hammers, pulverizers, hydraulic shears, wood grapples, hydraulic breakers, buckets, thumb clamps, stonegrabs, etc.
The core value of these attachments is to enable an excavator to be used for multiple purposes the more attachments configured, the more versatile the application. Some of these attachments are not only suitable for excavators but can also be installed on other hydraulic vehicles such as loaders, dualpurpose machines, and slide loaders, further reducing the equipment investment cost.
Practical Application of the Three Core Components
Hydraulic Shears: Essential tools for dismantling scrapped vehicles, ships, and steel structures
- Working principle: The hydraulic shears operate based on the principle of scissors. They are powered by the hydraulic system of the excavator and are driven by hydraulic cylinders to open and close the upper and lower blades, generating a tremendous shear force, which can cut steel, car chassis, ship plates, etc.
- Typical scenarios:
Disassembly of scrapped vehicles, cutting of the chassis and A/B beams
Cutting of used ships, division of ship body steel plates
Demolition of steel structure factories, cutting of steel beams and columns
- Advantages: High cutting force and high efficiency. It is 5 to 8 times faster than manual oxygen cutting, and there is no risk of fire or harmful gases.
Interruptor hidráulico: The preferred choice for building demolition, mining operations, and road surface demolition.
- Working principle: The hydraulic system of the excavator drives the internal piston of the crushing hammer to move back and forth at high speed. It violently strikes the drill rod, transferring the concentrated impact force to concrete, rocks and other hard objects, causing them to break instantly.
- Typical scenarios:
Building demolition: walls, stairs, foundations
Mining operations: stripping surface layers, secondary crushing
Old road surface renovation: demolition of cement and asphalt pavements
Tunnel excavation: tunnel construction
- Advantages: High impact force, stable operation; One small excavator equipped with a crushing hammer can replace the work of 6 to 8 manual workers, significantly reducing the construction period.
Pile Hammer: Construction of HighRise Buildings, Bridges, and Photovoltaic Pile Foundations
- Working principle: The pile driver uses the hydraulic system of the excavator to drive the hydraulic motor, which in turn causes the eccentric block to rotate at high speed, generating highfrequency vertical vibration. This enables the steel pipe piles, concrete piles, wooden piles, photovoltaic piles, and other pile structures to gradually sink into the ground.
- Typical working conditions:
Pile driving for building foundations
Construction of bridge pile foundations
Pile foundations for photovoltaic power stations
Construction of sheet pile revetments
- Advantages: The highfrequency vibration (1500-3000 vpm) causes the soil around the pile to liquefy, reducing the resistance; it can be used for both driving and extraction; it has little impact on the surrounding area and low noise; the integrated design results in a low failure rate.
Universality and Customization of Accessories
The attachments developed by METDEEM all utilize the hydraulic system on the machinery as their power source. Therefore, they are not limited to excavators. As long as the carrier has sufficient hydraulic flow and the appropriate connection method, they can all be adapted:
- Loader: Equipped with quick connectors and woodgrabbing devices, used for material yard loading and unloading.
- Bachone Loader: Installed with impact hammers or hydraulic shears to complete smallscale demolition.
- Skid SteerLoader: Equipped with compactors or rotary cutters for road maintenance and trench compaction.
METDEEM can customize the size of the pin shaft and the oil passage interface according to the connection methods of different carriers, enabling the same set of tools to be circulated among multiple machines, thereby further reducing investment costs. In China, mechanized operations have completely replaced manual labor, and the rational use of tools can make infrastructure construction more efficient and safe.

| interruptor hidráulico | Plunger reciprocating impact on the shank | Used for construction demolition, mining, and road demolition | Excavators, Sliding Loaders |
| martillo pila | Highfrequency vibration for sinking piles | Used for foundation piles of buildings, photovoltaic piles, and steel sheet piles | Excavadoras |
| Quick Coupler | Hydraulic/ Mechanical locking mechanism | 30 seconds to replace the equipment, enabling multipurpose use with one machine | Excavators, Loaders |
| Wood Grapple | Driven by hydraulic cylinder, the claws open and close | Used in wood storage yards, straw handling, and stone transportation | Excavadoras |
| Compactor | Highfrequency vibration with eccentric blocks | Used for subgrade compaction, slope compaction, and foundation backfilling | Excavators, Sliding Loaders |

Preguntas frecuentes
Q: Can the attachments of METDEEM only be installed on excavators?
A: No. As long as the carrier (such as a loader, dualpurpose vehicle, or sliding loader) has sufficient hydraulic flow and the appropriate connection method, it can be adapted. We can also customize connection brackets according to your equipment.
Q: Can my small excavator (3ton) be equipped with a hydraulic cutter or a pile driver?
A: Yes. METDEEM offers lightweight hydraulic cutters and mini pile drivers specifically designed for small excavators. They are suitable for dismantling scrap vehicles, light steel structures, or driving small piles. Please provide the model of the excavator and the hydraulic parameters, and we will precisely match them for you.
Q: Is the installation of the quick connector complicated? Does it require any modification to the oil pipeline?
A: It’s not complicated. Usually, just installing a set of hydraulic control valves or using the existing crusher pipeline is sufficient to enable a oneclick switch of attachments in the driver’s cabin. We provide detailed installation drawings and technical support. Generally, the repair shop can complete the installation.
