The gripping apparatus comprises mechanical grippers which are equal to each other and may be grouped side by side in battery formation. The grippers are formed each by two vertically superposed levers (1, 6) acting along a vertical plane and interconnected at a common fulcrum point (7) and are urged in the closing direction by resilient means (9) and are urged in the opening direction by a centralized mechanical system comprising a shaft (10) which cooperates transversely with the upper levers (6) of said grippers, which is supported by the same structure carrying said grippers and which may be selectively raised and lowered by one central motion unit (13). |
