Medium Girder Bridge - Parts

Parts

The MGB parts are fabricated from a specially developed zinc, magnesium, and aluminum alloy (DGFVE 232A). This enables a lightweight, high strength bridge to be built. All except three parts weigh under 200 kg. Most parts can be handled easily by four soldiers.

Famous quotes containing the word parts:

    “Yea, worse than death: death parts both woe and joy:
    From joy I part, still living in annoy.”
    —Sir Philip Sidney (1554–1586)

    “still a betrayal room for the till-death-do-us
    and yet a death, as in the unlocking of scissors
    that makes the now separate parts useless,
    even to cut each other up as we did yearly
    under the crayoned-in sun.”
    —Anne Sexton (1928–1974)

    “This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
    —Henry David Thoreau (1817–1862)
