An apparatus comprising a mobile carrier operable for transporting a reel of oilfield tubing across ground. The mobile carrier comprises a frame comprising a first frame portion, a second frame portion, and a central frame portion extending between the first and second frame portions. The first, second, and central frame portions define an opening for receiving the reel. The mobile carrier also comprises a locking mechanism operable to engage and rotate the reel within the opening, and a plurality of wheels supporting the frame on the ground. The plurality of wheels comprises a plurality of first wheels operably connected to the first frame portion and a plurality of second wheels operably connected to the second frame portion. The opening interposes the plurality of first wheels and the plurality of second wheels.

An outrigger pad assembly includes a base having a bottom surface for engaging an underlying support surface and a top surface opposite to the bottom surface, a force sensor mounted to the base, and an interface body. The interface body includes a lower cavity at least partially defined by a first inner sidewall, an upper cavity at least partially defined by a second inner sidewall, and a coupling body having a latch configured for selective with an outrigger jack. The force sensor is disposed in the lower cavity in sliding contact with the first inner sidewall such that the interface body is movable relative to the force sensor. The outrigger pad assembly may be part of an outrigger assembly of a lifting vehicle.

A trailer stabilizing device for stabilizing a parked freight trailer, the trailer stabilizing device comprising a frame separate from the support frame of the parked freight trailer, the stabilizing device frame having mounted thereto wheels and a hitch, the stabilizing device including a repositionable jack.

A system for modifying the range capability of an electric vehicle includes a vehicle body having a front axle and a rear module secured to the vehicle body. The rear module includes a rear axle and the rear module is detachable from the vehicle body and replaceable with another rear module. The rear modules may include different range extension capabilities. The rear modules may include a battery or a combustion engine that may supplement the standard battery and electric motor of the vehicle. A pair of laterally translatable pins of the rear module may be moveable into and out of engagement with the vehicle body. The rear module may also include vertically extending posts that engage with the vehicle body. The vehicle body may be raised to disengage the posts from the vehicle body.

The technology relates to autonomous vehicles having hitched or towed trailers for transporting cargo and other items between locations. Aspects of the technology provide a smart hitch connection between the fifth-wheel of a tractor unit and the kingpin of a trailer. This avoids requiring a person to make physical pneumatic and electrical connections between the fifth-wheel and kingpin using external hoses and cables. Instead, the necessary connections are made internally, autonomously. For instance, the fifth-wheel may provide air pressure via one or more slots arranged on a connection surface, and the trailer is configured to receive the air pressure through one or more openings on a contact surface of the kingpin. An electrical connection section of the fifth-wheel may also provide electrical signals and/or power to an electrical contact interface of the kingpin. Rotational information about relative alignment of the trailer to the tractor unit may also be provided.
