Embodiments of the disclosure generally concern equipment for use in operations at oil and gas wells, particularly a structure to transport and locate large diameter electrical cables, such as those used to connect turbine generators to electric pumping units on an oil and gas well site. More specifically the embodiments of the disclosure concern methods and apparatus for transporting, positioning, and manipulating large diameter power cables at the well site of oil and gas wells with a cable transport structure using longitudinal cable retaining members to create channels to store the cables and an end rack to fold extra length of the cable back onto the cable transport structure.

A barrier transfer machine includes a moveable chassis, an entry snout, an exit snout, a conveyor system, and a control system that aligns the entry snout with road barriers before the road barriers are picked up. The control system includes a barrier position sensor; an entry snout position sensor; and a processing system.

A system and method of determining orientation of a physical location on a cart or end effector located on the cart in an independent cart. system receives a feedback signal from a sensor on the cart, A multi-axis device may generate three or more signals corresponding to X, Y, and Z axes orientations. Processing may be performed on the signals to generate a value of yaw, pitch, or roll of the cart. The feedback or processed signals are transmitted from the mover to a remote device external from the track. The real-time orientation information may be used to implement closed-loop control of an actuator mounted on or external to each cart as the cart travels along the track, Power for the devices on the mover may be provided by a battery mounted on the cart or by a wireless power transfer system.
