A traffic barrier lifter (10) having a pair of opposing arms (12) carrying a vacuum pad (14). An articulating mechanism (16) opens and closes the opposing arms (12) such that the vacuum pads (14) can clamp onto a traffic barrier. Each pad (14) equipped with one or more vacuum reservoirs (20). These reservoirs (20) are in fluid communication with a vacuum source (22). The vacuum line (24) running from the reservoir (20) to the vacuum source (22) has a check valve (26). In the event of a power failure to the vacuum source or failure of the vacuum source (22) itself, the check valve (26) closes to maintain vacuum in the reservoir (20). The traffic barrier lifter (10) being attachable the boom (46) of an excavator or other appendage of a piece of heavy equipment. |
