Abstract:
A concrete breaker head adapted for attachment to a skid loader with hydraulically activated releasable latches comprising:a counterbalanced hammer member, an impact support member and an attachment means for attaching said hammer member to the skid loader;the counterbalance hammer member comprises a tubular support housing having a first end and a second end, a counter weighting means for stabilizing and balancing the moment of inertia of the hammer member about a pivoting axis of rotation, an impact head portion disposed at the first end, and a tubular supporting arm structure integrally disposed near the second end in substantially orthogonal arrangement with, a side portion of the housing of said hammer member for uniformly distributing localized impact stresses therethrough, said supporting arm structure being pivotally and integrally attached to the attachment means and the impact support member, respectively for raising and selectively lowering the hammer member;the impact support member comprises at least one beam member having a first and second combination dampening and constraining means fixedly attached thereto for dampening reaction impacts from the hammer member and constraining said hammer member thereto, the counterbalanced hammer member, attachment means and impact support member form a single integrated structure for releasable attachment with one portion of the skid loader via the attachment means, and wherein the impact support member further comprises at least one inclined support strut for supporting the integrally connected attachment means and pivotally attached supporting arm structure in a resting position when unattached to the skid loader.
