Underground overhead monorail system spaces trolley-slung coupling swivel axes from center vertical axes to prevent trolley and cable collisions in curves.

摘要

The swivel axis (S2,S3) of the coupling bar (5) pivotally fixed to the trolleys (2,3) is spaced from the vertical center axes (MHA2,MHA3) of the trolleys by less than or equal to the shortest interval (A) between the trolley wheel (6) center axes and the vertical center axes (MHA2,MHA3). The coupling bar is connected to the transport pan (11) whose width (B) measured at right angles to the bar equals the inside width (W) of the transport frame (7) plus assembly play (MS). The bar (5) is secured to the outer end of a coupler by a releasable coupling and the far end of the coupler has a bearing eyelet pierced by a bearing bolt to constitute this bar swivel bearing.
