Overview of Side Type Hydraulic Breaker
A hydraulic breaker, also called a rock breaker or hydraulic hammer, is a high-impact tool attached to an excavator. Side-type hydraulic breakers have a setup where the hitting part lines up with the excavator’s boom and arm. This simple design provides direct impact force. It avoids the extra size found in top or quiet models.
METDEEM’s Side Type Models
À METDEEM, we make the DM68 Hydraulic Breaker Side Type and DM195 Hydraulic Breaker Side Type to handle various work needs. Our side-type breakers focus on basic design, solid output, and low cost. DM68 fits right in for city-building jobs, DM195 fits in for mining and demolition tasks. For instance, in a busy downtown area, these tools help crews tear down old walls quickly and mine various mines without adding too much weight to the machine.
Key Components and Structure
Housing and Frame Material
The housing and frame of METDEEM breakers use Q335Mn plate. This material stands up to wear, stays crack-free, and holds its shape. Even during tough hits, the frame stays strong. Workers on a site can count on it not to bend or break after long days of use.
Piston and Chisel Assembly
The piston comes from CrNiMo alloy steel. It goes through several steps to build toughness and last longer. This part hits the psiton straight on. The chisel or tool usually comes from high-hardness 42Cr steel. It resists wear and handles constant pounding against rock or concrete. In real jobs, like breaking up a rocky hillside, this setup keeps going without quick breakdowns.
Hydraulic Integration and Flow Testing
METDEEM breakers connect smoothly to the excavator’s oil lines. Before shipping, each unit gets a full check on its oil flow. This step makes sure every breaker runs at top level. It also matches well with many excavator types. Imagine hooking one up to a Komatsu® machine; the fit is tight, and it starts working right away.
Hydraulic Operation Principle
How hydraulic energy is converted
Hydraulic breakers take oil from the machine’s system to push an inside piston. The piston then strikes the chisel. In turn, the chisel cracks the ground material.
Role of the piston in impact delivery
The piston needs to handle tiny shape changes, fight wear, and resist rust. It stays whole under pressure. This part carries the main force, changing the oil push into fast motion. Without it, the breaker couldn’t deliver those sharp blows.
Energy transfer to the chisel
After the piston speeds up, it passes power to the chisel. The chisel digs in or splits rock or concrete with quick hits. These can reach up to 600 bpm in models like the DM68 Hydraulic Side Type Breaker. On a quarry site, this means breaking large boulders into smaller pieces in minutes, speeding up the whole operation.
Advantages of Side Type Design
Compact structure benefits
Side-type breakers have a basic build. This cuts down on weight and makes setup and fixes easier. They work great for small to medium machines. A contractor might pick DM68 for a 5-ton excavator because it doesn’t add bulk that slows things down.
Higher Breaking Efficiency
Side-type hydraulic breakers deliver more direct impact energy thanks to their simplified frame structure. With fewer components absorbing force, they achieve higher breaking efficiency and reduced internal wear. This makes them especially effective for continuous heavy-duty work where strong, consistent power output is required.
Ease of maintenance and service
Our products run quicker and hit harder. This boosts work speed, cuts down on damage, and shortens job times. In the end, it saves money on runs. Plus, with fewer pieces in side-type builds, checks, and swaps take less time. A mechanic can often fix a worn bushing in under an hour, getting the team back to work fast.
Compatibility with Construction Equipment
Mounting on excavators
METDEEM side-type hydraulic breakers fit many excavator makes like CAT®, Komatsu®, Volvo®, Sany®, XCMG®, and others. We have units like DM68 for 5-ton excavators and DM140 for 19-24 ton excavators. This wide match means crews can swap tools between machines on the same site.
Hydraulic system requirements
Various models need different flow amounts and pressure settings. For instance, the DM53 calls for 25-50 L/min of oil flow and runs at 12-15 MPa working pressure. This range lets them work with several kinds. It keeps things flexible, so construction company can stock them for different customer needs.
Recommended METDEEM models by tonnage
- DM40: For 1.5-1.7 ton excavators.
- DM53: For 3.5-4.5 ton excavators.
- DM100: For 11-16 ton excavators.
- DM135: For 16-18 ton excavators.
- DM190: For 50-60 ton excavators.
- DM230: For 75-100 ton excavators.
These units come with changeable speeds, gas storage choices, and different chisels for varied jobs. A small contractor may choose the DM40 for light-duty applications, while a big mine goes for the DM190 to tackle heavy rock.
Applications in Construction and Mining
Use in urban demolition projects
Side-type hydraulic breakers suit tasks like fixing sidewalks, pulling out bases, and careful knockdowns in cities. Their control and handling make them a good choice. Picture a crew in a tight street; they use the breaker to chip away at old pavement without harming nearby buildings.
Role in mining and quarrying operations
In mining, road knockdowns, and similar areas, hydraulic breakers act as key add-ons for big machines. Their output affects job speed and costs directly. METDEEM’s side type models come with sturdy hit systems that break rocks well. In a quarry, for example, they split granite blocks efficiently, helping load trucks faster and meet daily targets.
Performance on reinforced concrete and rock
Our hydraulic breakers use high-strength alloy steel and smart oil system plans. This gives them strong hits, quick entry, and good speed. They handle thick concrete layers and tough stone faces without fail. Take a bridge repair job; the breaker pounds through reinforced slabs, clearing the way for new pours in half the usual time.
Conclusion
METDEEM side-type hydraulic breakers combine durable construction, efficient hydraulic systems, and easy maintenance to deliver reliable performance in a wide range of construction and mining tasks. Their compact design, higher breaking efficiency, and compatibility with various excavators make them ideal for urban demolition, quarrying, and heavy-duty projects. By choosing the right model for the job, operators can achieve faster, safer, and more cost-effective results on every site.
FAQ (questions fréquentes)
Q: Are side-type breakers less powerful than top types?
A: Not necessarily. They are designed differently but can deliver equal performance when properly matched with carrier machines.
Q: Can METDEEM side-type breakers be used for underwater work?
A: While primarily designed for land use, custom sealing solutions can be explored upon request.
Q: How often should I service my METDEEM breaker?
A: Basic inspection should be performed daily. Full maintenance, including seal checks, should be done every 500–800 hours, depending on usage.
Q: Do you offer a warranty on your products?
A: METDEEM Excavator Hydraulic hammers are guaranteed against failure due to defective design, materials, or workmanship for a period of one year or 2,000 hours.
