Abstract
Provided is an actuator apparatus including a positioning actuator device configured to position a first carrier member of the actuator apparatus. The positioning actuator device includes a first hydraulic fluid actuator having a first clamping means and a second hydraulic fluid actuator having a second clamping means, wherein the first and second hydraulic fluid actuator are configured to alternately clamp around a guide arrangement for moving the positioning actuator device along the guide arrangement. The first carrier member is provided with a first coupling member configured to be releasable coupled to the positioning actuator device. A method of positioning a first carrier member by means of the positioning actuator device is provided.
Claims14
A method of positioning a first carrier member and a second carrier member by means of a positioning actuator device, comprising:
- a first hydraulic fluid actuator having a first clamping means and comprising a second hydraulic fluid actuator having a second clamping means, which are configured to alternately clamp around a guide arrangement for moving the positioning actuator device along the guide arrangement;
- the first hydraulic fluid actuator comprises a first cylinder encompassing a first piston comprising the first clamping means configured to clamp around the guide arrangement;
- the second hydraulic fluid actuator comprises a second cylinder encompassing a second piston comprising the second clamping means configured to clamp around the guide arrangement;
- wherein the first piston is slidingly arranged in the first cylinder dividing its interior in a first and second cylinder chamber;
- the second piston is slidingly arranged in the second cylinder dividing its interior in a third and fourth cylinder chamber;
- the first carrier member is provided with a first coupling member configured to be releasable coupled to the positioning actuator device;
- the method comprises the steps:
- couple the first carrier member and the positioning actuator device to each other;
- move the first carrier member by means of the positioning actuator device for positioning the first carrier member into a first position;
- lock the first carrier member and/or uncouple it from the positioning actuator device, wherein the first coupling member is configured to be releasable coupled to a second coupling member of the second carrier member;
- the method comprising the further steps:
- couple the first carrier member, the second carrier member and the positioning actuator device to each other;
- move the first and the second carrier member by means of the positioning actuator device for positioning the first carrier member into the first position;
- lock the first carrier member and uncouple it from the second carrier member;
- move the second carrier member by means of the positioning actuator device for positioning the second carrier member into a second position;
- and
- lock the second carrier member and uncouple it from the positioning actuator device.
