Abstract
A pavement breaker has a housing, a hammer mechanism mounted within the housing, and at least one handle moveably mounted on the housing. The handle(s) can move in a vertical direction when the pavement breaker is orientated in its normal operation orientation. A sensor is mounted within the housing for detecting when the handle(s) is moved towards or at its uppermost position. If the sensor detects such handle position, the hammer mechanism is deactivated.
Claims15
A pavement breaker comprising:
- a housing having two opposite side panels defining apertures on two sides of the housing;
- a hammer mechanism mounted within the housing;
- two handles moveably mounted on the housing, the two handles having ends received within the apertures in the side panels of the housing, the two handles being moveable relative to the housing in at least in a vertical direction between at least an upper position and a lower position when the pavement breaker is orientated in a normal operation orientation;
- a rod having two ends coupled to the ends of the two handles, the rod extending between the side panels of the housing and being rotatable around a rotation axis with movement of the two handles between the upper position and the lower position;
- and
- a sensor mounted within the housing, the sensor interfacing with the rod to detect movement of the two handles to the upper position relative to the housing based on rotation of the rod around the rotation axis relative to the sensor;
- wherein, when the sensor detects that the two handles are moved to the upper position, the hammer mechanism is deactivated.
