stations hoist for landing stages

摘要

The device 9 is composed of two rams 34, 34' which are articulated by swivel articulations 14, 14', 15, 15' on the one hand on the outer portion 5 of the footbridge and, on the other hand, on a sole plate 16 anchored in the traffic area. These jacks form a trapezoidal quadrilateral articulated perpendicular to the longitudinal axis of the footbridge and they can be actuated, either together, or separately, in the same direction (raising, lowering), or in opposite directions (pivoting) thus forming a predetermined angle between them. Application, especially in large airports, for ensuring the link between an air terminal building and the interior of the commercial aeroplanes. IMAGE
