The present invention provides a cargo falling prevention system for a vehicle and a control method, which can determine a defective loaded state of cargo at an early stage to prevent the cargo from falling off a vehicle so as to avoid a collateral accident. Further, the present invention provides a cargo falling prevention system for a vehicle and a control method, which can allow a driver to recognize falling of cargo and to take a quick action to cope with the falling of the cargo.

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.

A pipe coil lifting device includes a superstructure with a central longitudinal member and at least two supports attached to opposite sides of the central longitudinal member, with two channels at the outside long-edges of the superstructure attached to the supports, with a convex upper surface attached to the supports of the superstructure.

Techniques for implementing a pipe deployment system that includes a pipe reel, in which the pipe reel includes reel ends and a reel drum and the pipe reel enables a pipe segment to be wrapped on the reel drum. The pipe deployment system includes a brake assembly with a brake wheel having a shaft socket keyed with flat inner surfaces, and a shaft adapter assembly, which includes an adapter head to be coupled between the pipe reel and the brake assembly. The adapter head includes an adapter shaft keyed with flat outer surfaces, in which the adapter shaft matingly interlocks with the shaft socket and is to be partially inserted through a reel end of the pipe reel, and a rotation control pin coupled to the adapter shaft, in which the rotation control pin is to be inserted between adjacent reel spokes in the reel end of the pipe reel.

The presently disclosed subject matter relates to trailers and systems for lifting and carrying spools. According to an aspect, a trailer includes a frame comprising a first side portion and a second side portion. The trailer also includes a first rack and a second rack attached to the first side portion and the second side portion, respectively, each rack defining multiple notches.
