The invention discloses an overhead single-track
train system, which is a single-track
train running between an upper and a lower auxiliary main single tracks and an overhead single-track
system in which an upper and a lower rows of multiple tracks formed by two pairs of main auxiliary single tracks arranged on both sides of the same I-
shaped beam. The single-track
train is a light main auxiliary single-track train which consists of narrow train body with small cross section, a plate-shaped
shock absorber, a main track wheel motor directly driving a main track wheel, an auxiliary wheel in parallel with the train and a small single main track wheel for bearing; the main structure of the overhead single track is a
main bearing beam with I-shaped cross section, which consists of an I-shaped upper
flange of girder, a horizontal lower
flange and a middle vertical wall; both the upper and the lower flanges are structures with thick root and thin
flange edge; the middle vertical wall is provided with a structure hole; the I-
shaped beam of the upper flange is formed by an auxiliary track support arm, in which the main body is a reversed T-shaped main beam; the T-
shaped beam structure is the same with a corresponding part of the entire I-shaped beam; the main single tracks are paved at the edge of the lower flange; the auxiliary single tracks are arranged on the edge of the upper flange or the top of the single-track support arm; both ends of the I-shaped beam are supported by a T-shaped
pier; the invention is characterized by low cost, low
energy consumption and
low noise.
