A container handling vehicle picks up storage containers from a three-dimensional grid of an underlying storage system. The container handling vehicle includes a vehicle module part (P1); and a container lifting part. The vehicle module part (P1) includes a first set of wheels for moving the container handling vehicle in a first direction (X) and a second set of wheels for moving the container handling vehicle in a second direction (Y). The second direction is perpendicular to the first direction. The container lifting part extends sideways as a cantilever from the vehicle module part (P1) and includes a hoist frame (P2) with an opening (OSP) defining an access perimeter; a hoist mechanism carried by the hoist frame (P2); a plurality of lifting bands connected to the hoist mechanism and guided by the hoist frame (P2); and a lifting frame for releasable connection to a storage container, the lifting frame being suspended in a horizontal orientation from the hoist frame (P2) by the plurality of lifting bands. The lifting frame has an opening (OLF) defining an access perimeter. The access perimeter of the opening (OSP) in the hoist frame (P2) corresponds in shape and alignment to the access perimeter of the opening (OLF) in the lifting frame to allow access to items in the storage container through the respective openings (OSP, OLF) when the lifting frame has been lifted up to the hoist frame (P2) by the hoist mechanism.

Methods, apparatus, and systems are provided for rigging interfaces couple to winch cable terminals that protect outer surfaces of fairleads and rigging devices as connections between objects. In one example, a rigging interface may include curved surfaces adapted to nest against a fairlead. In another example, a rigging device may have one or more removable elements allowing for coupling of the device to other objects.

A method of spooling a crane rope (2) onto a crane drum through a crane rope spooling system (1) from a reel (31) under a predetermined back tension is described and includes the steps of: unspooling the crane rope (2) from a reel (31) and passing the crane rope through a tensioning system (10) comprising a primary back tensioner (12) and a secondary back tensioner (16); gripping the crane rope (2) within the secondary back tensioner (16) and thereby preloading the crane rope (2) with tension prior to the crane rope (2) passing through the primary back tensioner (12); and applying a predetermined back tension to the crane rope (2) with the primary back tensioner (12) as the crane rope (2) is being spooled onto the crane drum under the predetermined back tension. A crane rope spooling system (1) for spooling crane rope (2) onto a crane drum under a predetermined back tension is also described, said system (10) comprising a tensioning system (10) comprising at least a primary back tensioner (12) and a secondary back tensioner (16) and a reel (31).

Systems and methods for hoisting a top drive of a drilling rig. An example system includes a hoisting system having a linear electric motor operable to raise and lower the top drive. An example method includes commencing operation of a processing device to cause operation of the linear electric motor to raise and lower the top drive. The linear electric motor may have a stator connected to and extending vertically along a mast of the drilling rig, and a rotor connected to the top drive and operable to move relative to the stator. The rotor may be connected to the top drive via one or more flexible lines.

UAV tether systems are provided that reliably deploy and retract cables capable of high-power and high-bandwidth data transmission. The tether system spools cables in a single layer to promote heat dissipation thereby allowing the use of lower-diameter cables. The tether systems further utilize a lightweight converter that achieves a high-voltage power transmission across a cable that is stepped down to a plurality of lower-voltage outputs usable by a UAV and accompanying payloads. The converter is constructed in a manner that promotes heat dissipation through the use of multi-layer PCBs and separate power modules PCBs mounted above main PCBs to create a cavity where forced air can reach heat sinks affixed to the power modules that extend into the cavity.
