Abstract:
Spreading tool (1) for widening openings, in particular for use in extricating trapped persons, having a drive (3) to which a pressurized medium (4) is applied and, coupled therewith in order to effect a synchronous counter-pivoting motion in the form of cutting and/or spreading elements, pivotably mounted pivot arms (16, 17) in a housing accommodating the drive (3) and drivingly linked to a pressure ram assembly (48) which is displaceable in the direction of a parallel extending longitudinal central axis (53) substantially parallel with a pivot plane (20) of the pivot arms (16, 17), characterised in that finger-type driving elements (25, 26) are provided in projecting end regions (23, 24) of the pivot arms (16, 17) in order to operate the pressure ram assembly (48), having operating jaws (38, 39) facing two pressure rams (46, 47) and enclosing them in a U-shaped arrangement in a part region in the circumferential direction, being pivotably linked to the pressure rams (46, 47) via pivot bearings.
