The present invention concerns an apparatus for treating surfaces or carrying out maintenance/inspection tasks of the top of a vertical stabilizer (31) of an aerial vehicle by at least one technician comprising: a single overhead crane (4) hanged on a roof (100) of a hangar building, a single suspended vertically movable lateral teleplatform unit (30) comprising a telescopic mast (2) connected to the single overhead crane (4), a suspended staging structure (20) firmly connected to the overhead crane (4) by a supporting structure (5), the suspended staging structure (20) comprising at least one working platform (61,62) for treating or carrying out maintenance/inspection tasks of the vertical stabilizer (31) of the aerial vehicle at different heights by at least one technician, the length of the overhead crane (4) does not extend beyond the vertical axis (A) of the vertical stabilizer (31), characterized in that the suspended staging structure (20) is not vertically movable and is independent from the vertically movable lateral teleplatform unit (30) permitting to reach the suspended staging structure (20).

An apparatus for treating a surface of a structure includes a main carriage having an accessory carriage that is vertically movable with respect to the main carriage.

An electromechanical system operates through physical interaction with an operator, and includes a plurality of joints providing multiple degrees of freedom (DOF), including actuated joints and unactuated joints. The unactuated joints are distal with respect to the actuated joints and are in redundant DOF to the actuated joints. The system includes a plurality of actuators each configured to actuate one or more of the actuated joints, and a plurality of sensors each positioned with respect to a respective one of the actuated and unactuated joints. Each sensor is configured to measure corresponding joint data indicative of a position or angle of the respective actuated or unactuated joints. A controller in communication with the sensors receives the measured joint data as feedback signals, generates control signals using the feedback signals, and transmits the control signals to the actuators to thereby control an actuation state of the actuators.

Systems and methods for object guidance and collision avoidance are provided. One system includes a location sensor disposed on a movable crane. The system also includes a plurality of sensors disposed on a plurality of objects within a facility. The system further includes a controller having a receiver for monitoring signals transmitted from the location sensor disposed on a movable crane and the plurality of sensors disposed on a plurality of objects within the facility. The controller is configured to generate a travel path for the movable crane to move an object coupled with the movable crane based on the one or more intersection regions and generate an output signal to an alarm device to provide an alert, when at least one object of the plurality of objects is within a predetermined proximity of at least the object being moved by the crane.

A compact overhead traveling hoist system for transferring product elements from a remote marshalling area to an assembly line work station includes an elevated rail system with a fixed longitudinally extending runway rail and a laterally extending bridge rail which is displaceable along the runway rail. A rail trolley is carried for controlled bi-directional displacement along the bridge rail. A hoisting device is carried by the rail trolley and includes a base member, an object grappler carried with the base member operative to selectively engage, transport and release product elements between the marshaling area and the work station, a linearly expandable structure coupling the rail trolley and the base portion, and a hoist drive operative for raising and lowering the base portion/object grappler. A controller includes assembly line work station operator input control devices located on the object grappler to control all aspects of the operation of the hoist system.
