Patent ID: 8281811

Claim:
Large manipulator having a mast base that can be rotated about a vertical axis of rotation, via at least one drive unit, and is disposed on a frame, having an articulated mast composed of at least two mast arms, which mast arms can be pivoted, in limited manner, relative to the mast base or an adjacent mast arm, about horizontal articulation axes that are parallel to one another, in each instance, via another drive unit, in each instance, having a pendulum element that hangs down from a mast tip, having first and second setting elements disposed in a control device, and having a computer-assisted coordinate sensor that responds to output signals of the first and second setting elements, and activates the drive units of the articulation and rotation axes of the articulated mast in accordance with an adjustment path that is displayed via the first and second setting elements, relative to the current position of the mast tip, whereby the mast tip can follow the spatial movements of the pendulum element, and whereby the first and second setting elements have respective first and second inclination sensors disposed in a housing, said housing being releasably attached to the pendulum element, wherein the first and second inclination sensors are angled by an angle of 90° relative to one another, about an axis parallel to the pendulum element axis, and wherein the housing has a marking that indicates the orientation of at least one of the first and second inclination sensors within the housing.
