Improved means permits to visually follow the movement of the tools while sitting on the driver's seat of a lift truck and to protect the actuating parts from accidental impacts or other factors causing damages. In general, such means consists of pairs of horizontal guides (4, 5) which are arranged in parallel on a frame (2), the first horizontal guide being arranged over the second one. The guides comprise slides (6, 7) on which pairs of runners (8, 8'; 9, 9') are slideably mounted. The pairs of runners are integral with two operating units (10, 11). The central part of each guide (4, 5) shows a longitudinal groove, which is delimited by the inner part of the slides (6, 7) and has such dimensions that it comprises double-acting oil-pressure jacks (13, 14), arranged opposite to one another. <IMAGE> |
