Abstract: The present invention relates to a crane with a height-adjustably mounted control or personnel stand that can be lifted and lowered by at least two lifting elements, wherein the two lifting elements are articulated to a balancing rocker that is mounted on a rocker bearing head connected to the control or personnel stand so as to be luffable about a horizontal pivot axis, wherein a monitoring and/or safety device is provided to monitor and/or ensure the safety of the control stand. According to the invention, the pivot axis is configured as a measurement axis for detecting the load state of the luffable bearing of the balancing rocker and for providing a load signal to the monitoring and/or safety device.

Abstract: The present invention comprises a method for controlling a load-moving device by at least two persons, with the following steps: controlling the movement of the load-moving device by a first person; handing over control over the movement of the load-moving device to a second person; controlling the load-moving device by the second person. The present invention furthermore comprises a corresponding controller of a load-moving device with a first, in particular permanently installed operating unit and a mobile operating unit for controlling the movement of the load-moving device for the safe and efficient performance of the method.

Abstract: An operator controllable robotic device is disclosed. The robotic device comprises a support member, an upper robotic arm, a lower robotic arm, and a control arm. The upper robotic arm is coupled to the support member and has rotational movement in at least one degree of freedom relative to the support member. The lower robotic arm is coupled to the upper robotic arm and has rotational movement in at least one degree of freedom relative to the upper robotic arm. The control arm allows an operator to control the robotic device. The control arm is coupled to the upper robotic arm and has rotational movement in at least one degree of freedom relative to the upper robotic arm. The control arm allows a movement of the operator to control a movement of at least one of the upper robotic arm and the lower robotic arm.

Abstract: A slewing stop control apparatus and method, capable of executing, while performing the control of determining the target slewing velocity based on a remaining slewing angle from the actual slewing motion position up to the slewing stop angular position, an automatic control of re-slewing the slewing structure having been stopped before the slewing stop angular position. The apparatus executes slewing angular velocity control for deciding the slewing braking start timing to stop the stewing structure at a slewing stop angular position in accordance with a predetermined slewing deceleration and the subsequent target slewing angular velocity, based on the remaining slewing angle of the slewing structure. When the slewing structure stops before the slewing stop angular position due to disturbance despite the foregoing control, the target slewing angular velocity is corrected to be increased for generating slewing torque to restart the slewing.

Abstract: The present invention relates to a crane, preferably a truck crane, comprising a plurality of crane elements which are movable by actuators, a crane control unit for controlling and/or monitoring the movement of the crane elements, and at least one actuating switch for actuating the actuators. In accordance with the invention, the crane is characterized in that in the at least one actuating switch a logic module is integrated, by which the actuators can be driven directly corresponding to a respective switch movement, and the crane control unit can be connected with the logic module by a data transmission connection.

Abstract: The invention relates to a crane that comprises an electronic control for actuating drives for at least one lifting gear and for crane movements, which can be operated by an operator via manual input devices. Said manual input devices can be adjusted as regards their sensitivity (definition). In order to adapt the system behavior of the crane to the needs of different operators and different lifting requirements in an optimum manner, the electronic control is provided with at least two adjustments, selectable by the operator, that set for the manual input devices respective different sensitivities defined for the crane operation.

Abstract: A control system for a loading crane provided with a control site, the control system consisting of a control site for a crane operator, a directional control valve positioned external to the control site and arranged to control a hydraulic system of the crane to provide different operations of the crane, and a mechanical rod-driven control lever system influencing actuator spindles of the directional control valve for the control of the directional control valve from the control site of the crane. To provide an efficient control system, the directional control valve is arranged at the sides of the control site in such a way that the actuator spindles are in a substantially horizontal position.

Abstract: A crane is disclosed, with one or more moveable components. Manually-articulable controls (such as joysticks) are provided for controlling movement of the components. First, second, and third control circuits responsive to varied positions of the control are optionally connected to the control to provide first, second, and third sets of control signals each with differing responses to the control in a given position so as to move the components in a manner which mitigates instability or inaccuracy due to the physical acuity of the operator.

Abstract: Apparatus for the handling of truck trailers or transport containers and more particularly to an apparatus and method for a variable elevating cabin apparatus operable for controlled vertical movement within the framework of a gantry crane, wherein an operator positioned in the cabin may observe and control visual observation requirements for handling a work load from any elevation between ground level and the top of the crane.

Abstract: An apparatus and a method for controlling the operation of a reach tower crane, in which a horizontal boom can safely and securely be operated or stored by one operator in the cab, and in which even if sensors are out of order, the stability of the crane can be secured. The system has a plurality of sensors for detecting a condition of an actuator (6) actuating an apparatus to operate or store a horizontal boom (5), a controller (36) for sending a control signal based on signals from the sensors, and hydraulic apparatuses for controlling various actuators in accordance with the control signal. Further, an operation lever and an operation switch are used to extend or store the horizontal boom (5).

Abstract: An improved gantry crane that has a control cab mounted for vertical up and down movement substantially parallel with respect to the upstanding columns of the crane between a lowermost position adjacent the ground and infinite positions within a fixed range. One or both of the sill beams of the crane include a downwardly offset mid-portion extending adjacent to the ground but spaced therefrom with the mid-portion of one of the sill beams being positioned to receive the control cab when in the lowermost position thereof. A supporting beam supports the control cab therebeneath so that the operator in the cab has a 360 degree substantially unobstructed view in all directions.
