Electric breaker attachment

An attachment on a power machine comprising:

• an elongated hammer including an upper end in sealed communication with a gas accumulator and an opposing lower end;
• an elongated tool including an upper end having an impact surface and an opposing lower end having a work surface, wherein the tool is configured to be actuated when the lower end of the hammer collides with the impact surface of the tool;
• a hammer position sensor spaced apart from and located above the upper end of the hammer and configured to measure a location of the upper end of the hammer relative to the hammer position sensor, wherein the hammer position sensor is located through a wall in the gas accumulator;
• and
• a controller configured to electrically activate the hammer into a compression stroke and a firing stroke based on measurements gathered from the hammer position sensor.

An attachment on a power machine comprising:

• an elongated hammer including an upper end in sealed communication with a gas accumulator and an opposing lower end;
• an elongated tool including an upper end having an impact surface and an opposing lower end having a work surface, wherein the tool is configured to be actuated when the lower end of the hammer collides with the impact surface of the tool;
• and
• at least one electromagnetic coil that surrounds a portion of the elongated hammer;
• and
• a controller configured to electrically activate the at least one electromagnetic coil to actuate the elongated hammer into a compression stroke that moves the hammer in a first direction and a firing stroke that is further aided by compressed gas in the gas accumulator to move the hammer in a second opposing direction and cause the lower end of the hammer to collide with the impact surface of the tool to actuate the tool.
