| 摘要 |
A hydraulic assembly (41) includes a group of hydraulic cylinders (30-33) connected in series. The group includes at least three consecutive cylinder sets or stages (I-IV), at least in every stage (II-IV), which follows after the first stage (I), in relation to one end of said group, two parallel hydraulic cylinders (31-33) being included, which are disposed outside the cylinders of a preceding stage. The piston rods (31A, 32A) of the as described consecutive hydraulic cylinder stages are alternatingly turned forwards towards one end of the group and backwards towards the other end respectively. Between at least two of the consecutive cylinder pairs is connected a clamp-shaped yoke (36) having connection elements (37), which connect the piston rods (31A) in the one of said cylinder pairs to the piston rods (32A) in the other one of said cylinder pairs. |
