ABSTRACT:
There is described a paving breaker wherein vibrational forces arising from reciprocation of the breaker are reduced at the breaker handles by removing the conventional direct attachment of the handles to the breaker, and instead resiliently coupling the handles to the working bit. There is also described a support for a paving breaker said support having a powered lift provided with at least one ground engageable wheel. The powered lift is under the control of a manually operable control mounted in the support.
