A shearing blade for a cutting device includes a main body that has a seat and a blade insert that is arranged on the seat and forms a cutting wedge, wherein the cutting wedge forms a cutting edge via a flank face and a pressure face at an angle to the flank face. The seat has at least one undercut face that acts in a direction transverse to the flank face. When the blade insert is inserted, the undercut face interacts with at least one form-closure face formed on the blade insert, whereby a form closure taking effect transversely to the flank face is established. The blade insert is fastened to the main body by at least one pin-shaped plug-in connection element, which is oriented perpendicular to the flank face and which is arranged in aligned holes in the main body and in the blade insert.

Shearing blade having a blade insert

The invention relates to a spreader tip () for replaceable attachment to two pincer-like co-operating spreader arms () of a rescue tool (). Mounted on a working face () of the spreader tip () is at least one insert element () which protrudes from and has different material properties in comparison with the spreader tip ().

Spreader tip for a rescue tool

The invention relates to a cutting device providing a main frame body, at least one stationary cutting element disposed on the main frame body, a drive system disposed on the main frame body, in particular in the form of a fluid cylinder, and a cutting blade drivingly connected to the drive system and guided in its movement on the main frame body, which co-operates with the stationary cutting element. The main frame body and/or the drive system is made from an essentially light metal or a light metal alloy with a density of less than 5000 kg/m, in particular less than 3000 kg/m.

Cutting device, in particular rescue cutters

The invention describes a rescue apparatus () with prising arms () on a support housing () mounted in at least one pivot bearing arrangement () with a drive system () so as to be displaceable in pincer-like movement about a pivot axis () extending perpendicular to a longitudinal mid-axis () of the support housing (). Surface regions () with a higher resistance to wear than the resistance to wear of adjacent regions () are provided on at least mutually facing internal surfaces () of the prising arms ().
