Onshore Light Coiled Tubing Unit
A Coil Tubing Unit is a selfcontained multi-use machine that can approximately do anything a conventional service rig is capable of - with the exception of tripping jointed pipe. There are generally two types in shallow service - Arch and Picker. One uses a vertical elevator with a horsehead on top, and an injector hanging by winch line off it. The Picker units have a picker, and a horsehead bolted directly to the injector.
These type of coil tubing units have a semi-permanent drum mounted amidships (They are generally tandem drive Class 3 trucks, 40 feet (12 m) long or so)

Famous quotes containing the words light, coiled and/or unit:
“Haply your eye shall light upon some toy
You have desire to purchase.”
—William Shakespeare (1564–1616)
“Now remember courage, go to the door,
Open it and see whether coiled on the bed
Or cringing by the wall, a savage beast
Maybe with golden hair, with deep eyes
Like a bearded spider on a sunlit floor
Will snarl—and man can never be alone.”
—Allen Tate (1899–1979)
“During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.”
—George Bernard Shaw (1856–1950)
