A battery replacement apparatus includes: a battery replacement station including a floor on which an electrically powered vehicle can be stopped; a battery mounting table on which the first battery and the second battery can be mounted and which is movable below the electrically powered vehicle in a vertical direction; and a raising and lowering unit movable below the electrically powered vehicle in the vertical direction independently of the battery mounting table. The raising and lowering unit is movable between a raised position to which at least a part of the electrically powered vehicle has been moved upward from the floor, and a separated position separated downward from the electrically powered vehicle. The battery mounting table is capable of moving up to a position where the battery mounting table contacts a bottom surface of the first battery when the raising and lowering unit is located at the raised position.

A pillow lifting structure includes a bottom plate. The bottom plate is provided with a power unit. The power unit is connected to a linking unit. The top of the linking unit is covered with a cover. The power unit actuates to deform the linking unit for adjusting the height of the cover in time so as to adjust the height of the top surface of the pillow. The X-shaped linking unit of the pillow lifting structure is lifted by a driven arcuate gear with a push arm. This action is a direct push, and there is no power consumption. Only a small motor is required for actuation. Space and energy consumption are optimized by the direct push.

A system for controlling an industrial vehicle comprises an information linking device, a badge communicator, an operator badge, and a controller. The controller controls the industrial vehicle operating state by identifying that an operator possessing the operator badge has approached the industrial vehicle, communicating with the server via the information linking device to authenticate the operator as authorized to operate the industrial vehicle, and pairing the operator badge with the industrial vehicle upon determining that the operator is authorized to operate the industrial vehicle. Moreover, the controller controls the industrial vehicle operating state by controlling the industrial vehicle based upon a location of the operator badge relative to the industrial vehicle.

A heavy duty hydraulic positioner has headstock and tailstock carriages to support large and heavy work pieces to be processed in a manufacturing operation, such as robotic welding. Each carriage is independently movable along a column, and has a hard stop associated with each pre-program workpiece position, thereby providing accurate repeatability. Repeatability is further enhanced by linear, noncontact absolute encoders for the elevation axes of the headstock and tailstock, and rotary, noncontact absolute encoders for the rotary axes of the headstock and tailstock.

A method and apparatus may be present for moving a wing. A plurality of lifting assemblies may be attached to a first plurality of channels in a ring associated with the wing of an aircraft. A plurality of base assemblies may be attached to a plurality of fittings with a second plurality of channels associated with a fuselage of the aircraft. The plurality of lifting assemblies may be moved away from the plurality of base assemblies using a plurality of biasing systems such that the ring may move away from the fuselage.

A conduit de-coupling device includes a supply port, a coupler for selectively engaging a connected device, a link positioned adjacent the coupler, and a disconnect port. The link is moveable between a first position in which the coupler is secured in engagement with the connected device, and a second position in which the coupler is permitted to disengage the connected device. The link is biased toward the first position. The disconnect port is in fluid communication with a fluid source to receive pressurized fluid to move the link from the first position to the second position.
