Wireline Apparatus
For oilfield work, the wireline resides on the surface, wound around a large (3 to 10 feet in diameter) spool. Operators may use a portable spool (on the back of a special truck) or a permanent part of the drilling rig. A motor and drive train turn the spool and raise and lower the equipment into and out of the well – the winch.

Famous quotes containing the word apparatus:
“Ones condition on marijuana is always existential. One can feel the importance of each moment and how it is changing one. One feels ones being, one becomes aware of the enormous apparatus of nothingnessthe hum of a hi-fi set, the emptiness of a pointless interruption, one becomes aware of the war between each of us, how the nothingness in each of us seeks to attack the being of others, how our being in turn is attacked by the nothingness in others.”
—Norman Mailer (b. 1923)
