Abstract
Abstract A construction implement includes a vehicle having a boom, a compactor, and a compactor suspension system for supporting the compactor on the boom and for isolating the vheicle from vibrations caused by operation of the compactor. The compactor suspension system includes a frame mounted on the boom and at least one air bag mounted between the frame and the compactor. The alignment between the compactor and the boom is maintained by guide bars that extend from the frame into engagement with cooperating guide members on the compactor.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
180 words
A construction implement comprising: a compactor mechanism including a housing, dual striking members supported for reciprocation relative to the housing, a motor mounted on the housing, and means driven by the motor for effecting alternate reciprocation of the striking members; a vehicle for transporting the compactor mechanism and coupled to the motor for supplying operating power thereto; an articulated boom extending from the vehicle for manipulating the compactor mechanism both horizontally and vertically and for applying a force to the compactor mechanism during the operation thereof; a frame connected to the distal end of the boom; at least one air bag mounted between the frame and the housing of the compactor mechanism and comprising the sole supportive connection between the boom and the compactor mechanism so that the boom operates through the air bag to position the compactor mechanism horizontally and vertically and so that the force of the boom is applied to the compactor mechanism through the air bag; and cooperating guide means on the frame and the housing of the compactor mechanism for maintaining a predetermined alignment therebetween.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
49 words
The construction implement according to claim 1 wherein the cooperating guide means comprises a plurality of guide members extending between the frame and the housing of the compactor mechanism and structure for slidably receiving the guide members and thereby maintaining the predetermined alignment between the frame and the housing.
