A system includes a hoist drive mechanism that elevates and lowers a load hook from a boom and a detector that provides obstacle location and identification information. A processor receives the obstacle location and identification information from the detector and provides obstacle avoidance data in response thereto.

Systems and methods for operating a hoist and hook assembly may determine a position of a target using a position sensor. A hook assembly may be positioned in response to the position of the target as detected by the position sensor. Positioning the hook assembly may include articulating a boom coupled to a hoist, using one or more local thrust sources on the hook assembly, and/or moving an airframe relative to the position of the target.

A grabber for a load handling apparatus having an optical distance measuring device and a fastening mechanism that fastens the optical distance measuring device in a flexible manner to the grabber. The grabber may be provided in a crane, such as a boom crane, a bridge crane, a container crane or a gantry crane.

A vehicle door includes a door box with first and second walls and a second wall and a window frame module, in which a window frame, a first window shaft reinforcement and a second window shaft reinforcement are connected into a structural unit. The first window shaft reinforcement features a groove that accommodates an upper edge of the first wall. An upper edge of the second wall is covered by the second window shaft reinforcement.

A lift system for a rotor blade of a wind turbine includes a lifting device having a structural frame body having a root end and a tip end. The root end supports a root cradle and the tip end supports a tip cradle. The root and tip cradles each have a profile that corresponds to at least one exterior surface of the rotor blade so as to receive and support at least a portion of the rotor blade. Due to a shape of the rotor blade, when the rotor blade is installed in the lifting device and lifted uptower, the rotor blade can experience an asymmetric loading. Accordingly, the lift system also includes a variable airflow assembly coupled to tip end of the lifting device. The variable airflow assembly includes at least one surface moveable between a plurality of positions having varying resistances so as to counteract the asymmetric loading.

Aspects described herein include an end effector capable of prehending items using impactive and astrictive forces. The end effector includes an interface system having a deformable mounting plate and a pliable body member attached to the mounting plate. The end effector further includes a linkage system between a plurality of actuators and the interface system. The linkage system connects to lateral portions of the mounting plate.

A system for servicing a nuclear reactor module comprises a crane operable to attach to the nuclear reactor module, wherein the crane includes provisions for routing signals from one or more sensors of the nuclear reactor module to one or more sensor receivers.

A ceiling/overhead mounted delivery system includes a track configured to be mounted to a ceiling or overhead structure and extend in at least one of a first direction and a second orthogonal direction. A positioning tractor is attached to the track for motorized movement thereon. The delivery system may further include a delivery device, such as a selectively actuable germicidal light emitter. A third direction deployment module is coupled to the positioning tractor and the germicidal light emitter and is selectively adjustable to change a distance between the positioning tractor and the germicidal light emitter in a third direction. The third direction is substantially orthogonal to the first and second directions. A controller is configured to move the positioning tractor along the track, selectively operate the third direction deployment module to adjust the distance between the positioning tractor and the germicidal light emitter, and selectively actuate the germicidal light emitter.

The invention relates to an arrangement (600) for controlling a rotator, the arrangement (600) comprising a control device (100); a rotator (200) for a jib-carried tool (300); and one or more image sensing devices (700); wherein the control device (100) is configured to obtain one or more signals (702) from the one or more image sensing devices (700), obtain a location of a target object (500) based on the one or more signals (702), and control the rotator (200) based on the location of the target object (500). Furthermore, the invention also relates to a corresponding method, a vehicle comprising such an arrangement and a computer program.

Provided is an offshore wind turbine installation arrangement, including a lifting assembly realized to hoist a suspended load between a floating installation vessel and a wind turbine assembly, the lifting assembly including a crane supported by the floating installation vessel; a sensor arrangement realized to sense at least a motion of the floating installation vessel; and a controller realized to control elements of the lifting assembly on the basis of the sensed installation vessel motion to adjust the position of the suspended load relative to the wind turbine assembly. Also provided is a method of hoisting a load between a floating installation vessel and an offshore wind turbine assembly.
