Old pneumatic hammers retrofitted into electro-hydraulic hammers

Old pneumatic hammers retrofitted into electro-hydraulic hammers

The original pneumatic hammer foundation and anvil block require no modification. Openings are created on the left and right sides of the upper part of the pneumatic hammer frame to connect the new hammer rod and hammer head. The internal transmission components, hammer rod, piston, etc., of the original pneumatic hammer are no longer used. A completely new electro-hydraulic power unit is installed on top of the frame, accompanied by a new hydraulic station and pipeline system, nitrogen cylinder groups, and an electrical control system. This retrofitting transforms the hammer into a fully hydraulic electro-hydraulic hammer, resulting in simpler operation.

Product Features

Pain point

The front and rear cylinder bores are worn oversize; replacing components cannot restore lifting and striking performance.
Cracks in the hammer body cause air leakage or compression gas leakage between front and rear cylinders, and cannot be repaired.
Severe wear of transmission components, with abnormal noises persisting after partial replacement.
Failure to pass environmental impact assessment due to noise, vibration, and oil mist issues.

Advantages

Elimination of oil mist pollution, significant noise reduction, and improved working environment.
Increased weight of the falling parts during striking, resulting in higher impact energy.
Stable performance of the electro-hydraulic hammer with greatly reduced failure rate.
Upgradeable to automated electric-controlled striking with synchronized operation via manipulator.

Solution 1

Retains the original pneumatic hammer foundation and anvil block + new frame and electro-hydraulic power system.

Solution 2

Utilizes the original pneumatic hammer foundation, anvil block, and frame + electro-hydraulic power system.
