MTKS hydraulic hammers are not only an indispensable tool on any job site, they are also a strategic investment that directly impacts productivity, safety, and profitability in every project.
Efficiency and Power
They can generate thousands of blows per minute, transforming the excavator’s hydraulic pressure into powerful impacts.
This strength allows them to break reinforced concrete, hard rock, and pavement in just minutes, saving entire workdays of manual labor.
Thanks to their design, they deliver consistent performance even during extended operations, reducing the risk of overheating.
Versatility
Suitable for urban construction, mining, quarries, civil works, demolition, and trenching.
They perform reliably under extreme conditions: from confined indoor spaces to open and demanding environments such as tunnels or large-scale earthworks.
Being compatible with different excavator sizes (from 0.8-ton mini excavators to 25-ton industrial equipment), they provide an adaptable solution for virtually any job site.
Noise and Vibration Reduction
MTKS hammers are equipped with damping systems and reinforced housings that reduce vibrations transmitted to the machine and the operator.
This technology is especially valuable in urban areas or near residential buildings, where minimizing disturbances is essential.
Less vibration also means reduced wear on the carrier machine, extending the excavator’s service life and lowering maintenance costs.
Enhanced Safety
By automating the breaking process, operator exposure to physical risks from manual percussion tools is minimized.
The operator works safely from the excavator cab, reducing the chance of accidents from flying debris.
Additionally, the use of explosives in quarries or rock-breaking projects is avoided, which increases safety in sensitive environments.
Profitability and Cost Reduction
By accelerating execution times, overall project duration is reduced, leading to lower labor costs.
Their simple and predictable maintenance (regular greasing and nitrogen checks) makes them a very low operating cost alternative compared to other options.
Their versatility ensures that a single MTKS hammer can be used across multiple project types, maximizing equipment amortization.

Large-scale civil engineering: dams, tunnels, and hydroelectric plants.
Agricultural projects: digging wells or conditioning rocky land for irrigation and plantations.
Environmental protection: replace explosives, reducing vibrations and collateral risks in sensitive ecosystems.
Proper maintenance ensures that the hammer maintains its impact power, prevents breakdowns, and extends its service life. Below is the recommended schedule:
Greasing with graphite-based grease: it is essential to apply high-performance grease (preferably graphite) to the chisel and guide bushing.
This reduces friction, prevents overheating, and extends the chisel’s service life.
In extreme conditions of dust or humidity, greasing may be required even more frequently.
Check the chisel: look for wear, cracks, or deformation. A damaged chisel reduces impact efficiency.
Oil leaks: inspect hoses, fittings, and seals. Even small leaks can cause pressure loss and damage the hydraulic pump.
Hydraulic connections: ensure they are tight and free from dirt.
Check grease levels and look for possible looseness in the housing.
Nitrogen check: verify the pressure in the hammer’s accumulator chamber. Incorrect pressure leads to reduced impact force and piston fatigue.
Wear inspection: check bushings, pins, and shock absorbers (silent blocks). Replacing worn components avoids major failures.
Ensure there are no metallic particles in the oil or grease, which indicate internal wear.
Perform a thorough inspection: partial disassembly of the hammer to check the piston, valves, membranes, and seals.
Check the torque of main bolts.
Verify proper hammer alignment with the hitch, since misalignment accelerates wear.
Clean the excavator’s hydraulic filters to guarantee a clean and constant flow.
Professional workshop overhaul should include:
Replacement of seals, gaskets, and membranes.
Reconditioning of bushings and pins.
Piston verification using ultrasound or non-destructive testing methods.
Preventive replacement of critical components.
This semi-annual overhaul prevents serious failures and ensures the hammer continues performing like new.
