Problems |
Manipulators can be set to a specific weight in order to counterbalance it. This enables the load to be moved vertically without major force exertion. Alternatively, they can be equipped with a control that enables the height of different weights to be adjusted. This enhances their flexibility, but also constrains the user, who in this case must still be able to reach and operate the controls in addition to safely holding the load and the manipulator. |

Solution |
Where the height is controlled by detection of hand force, sensors are integrated directly into the manipulator handle. One sensor detects when a hand has enclosed the handle: only then does it enable the system, thereby preventing unintended movement. A second sensor detects forces applied by the hand in the vertical plane and controls the motor accordingly in assisting these movements. This arrangement supports intuitive and natural movement during work and simplifies operation. (See also EN 13557:2009, Section 5.1; EN 14238:2010, Section 5.5) |
