    • The present disclosure relates to a fluid actuator arrangement (100)and a method for control of a fluid actuator arrangement. The fluid actuator arrangement comprises a piston rod member (101),at least two cylinders (105, 106) each said cylinder having a piston body, and a clamping mechanism (102, 103) associated to each cylinder. Each clamping mechanism is arranged to engage and disengage the piston body of the cylinder to the piston rod member (101). The fluid actuator arrangement comprises further a control element (104) arranged to control a back and forward movement of the respective piston body (107, 108) so that forward movement is slower than the backward movement and to control the movement of the respective piston bodies in relation to each other such that at least one piston body is always moving forward and such that an overlap exists wherein at least two of the piston bodies are moving forward simultaneously during a cycle. Further,the piston body (107, 108) is engaged to the piston rod member in the forward movement and disengaged from the piston rod member in the backward movement.
