| 摘要 |
The invention describes a rescue device (1) having spreading arms (4, 5) which are mounted on a support housing (3) in at least one pivot bearing arrangement (20) and which can be moved by a drive device (2) like pincers about a pivot axis (17) which is perpendicular to a longitudinal center axis (18) of the support housing (3). Surface regions (41) having an abrasion resistance higher than the abrasion resistance of adjacent regions (42) are constructed on at least the opposing inner surfaces (26, 27) of the spreading arms (4, 5). |
