Tractor Unit - Crane

Crane

See also: Grapple truck

A tractor unit can sometimes have a mounted crane located behind the cab. The tractor unit can still pull a trailer using its fifth wheel, although it will carry less payload, due to the extra bulk of the crane. A crane truck is able to lift its load on site, and usually comes with stabilisers like those on mobile cranes. These cranes can come in sizes from a few tonnes - up to special heavy-duty ones that can lift in excess of 80 ton/mtr - for lifting intermodal containers and office units. Unlike a rigid truck with a crane, the tractor and crane have the advantage that they can be separated and repositioned relative to the load if necessary.

Famous quotes containing the word crane:

    “Yet, to the empty trapeze of your flesh,
    O Magdalene, each comes back to die alone.
    Then you, the burlesque of our lust—and faith,
    Lug us back lifeward—bone by infant bone.”
    —Hart Crane (1899–1932)

    “O Sleepless as the river under thee,
    Vaulting the sea, the prairies dreaming sod,
    Unto us lowliest sometime sweep, descend
    As of the curveship lend a myth to God.”
    —Hart Crane (1899–1932)

    “His thoughts, delivered to me
    From the white coverlet and pillow,
    I see now, were inheritances—
    Delicate riders of the storm.”
    —Hart Crane (1899–1932)
