    摘要： A machine includes a boom coupled to a movable carrier and at least one boom actuator adapted to actuate the boom. At least one boom sensor is configured to generate signals indicative of a spatial orientation of the boom. A drilling work device is coupled at a distal portion of the boom. First and second actuators are adapted to actuate the drilling work device. At least one drilling work device sensor is configured to generate signals indicative of a spatial orientation of the drilling work device. A controller receives signals indicative of the spatial orientation of the boom, receives signals indicative of the spatial orientation of the drilling work device, and actuates at least one of the at least one boom actuator and the first and second actuators through predetermined sequential steps to automatically position the machine in a shipping configuration.

    摘要： A tool carrier, which is also known as a top drive or a power swivel, for a well operation rig includes link arms coupled between the rotating hook assembly and the lower pipe gripping structure, the link arms each secured to the rotating hook assembly by a first rigid connection and secured to the lower pipe gripping structure by a second rigid connection such that the link arms can extend along well center even when operating in slant. Another tool carrier includes a hinge between the mast and the main housing. The hinge permits the tool carrier to be moved into a more central position when folded onto the rig chassis for transport.
