A PDU for use in an aircraft includes a wheel configured to convey cargo through a portion of the aircraft. The PDU further includes an armature rotatably coupled to the wheel. The PDU further includes a brake pad. The PDU further includes a hold solenoid configured to compress the armature against the brake pad by a brake amount in order to apply a hold braking force to the wheel by resisting rotation of the armature. The PDU further includes a release solenoid configured to apply a force to separate the armature from the brake pad in order to allow the armature to rotate. The PDU further includes a magnet configured to compress the armature against the brake pad by a drag amount that is less than the brake amount in order to apply a drag braking force to the wheel by resisting rotation of the armature.

A conveyor bed including a conveyor frame, a first set of rollers, a second set of rollers, and a pivotable frame is provided. The first set of rollers are coupled to the conveyor frame to transport an article from an upstream location to a downstream location. The pivotable frame pivotably coupled to a side of the of the conveyor frame. The second set of rollers mounted to the pivotable frame, positioned below the first set of rollers. A belt wrapped is around the second set of rollers, and selectively engages and disengages the first set of rollers in response to pivoting the pivotable frame based on predefined criteria.

A pipe retrieval machine has a frame defining a decoupling region and a travel axis and a transporting mechanism having a first gripping structure adjacent an infeed end of the machine and a second gripping structure adjacent an outfeed end of the machine. The decoupling region is disposed between the first and second gripping structures. A drive system is configured to move the first and second gripping structures at a steady state speed to direct the pipe along the travel axis. A decoupling device in the decoupling region has a decoupler that is automatically operable to engage a locking part of the coupling. The decoupling device is configured to selectively and automatically stop the pipe relative to the decoupling device, to disassemble at least one pipe section from the pipe, to move the detached pipe section from the machine, and to advance the remaining pipe for disassembly.

A modular transfer system with a primary flow system and a diverter system. The primary flow system includes a primary flow belt for conveying an article along a primary flow path from an infeed side of the modular transfer system to a pass-through side of the modular transfer system. The diverter system includes one or more diverter belts for diverting an article from the primary flow path towards a divert side of the modular transfer system. The primary flow belt includes multiple movable components contacting the diverter belt. The movable components can have one or more rotational degrees of freedom.
