Abstract
A hydraulically activatable working device includes a hydraulic cylinder and at least one first and one second partial piston provided therein. The partial pistons can be moved under pressurization by a hydraulic medium to perform a working operation. Each partial piston has an impact surface at its lower end against which the hydraulic medium may act. A piston rod is coupled to the hydraulic cylinder and has an impact surface at its lower end against which the partial pistons may act. The impact surface forms a first partial impact surface against which the first partial piston acts, and forms a second partial impact surface against which the second partial piston acts. The first and second partial impact surfaces do not overlap each other in direction across to the traversing direction.
