Abstract: A method and system for mounting an axle in a bore of a bogie mounted on a landing gear of an aircraft, the landing gear being in a gear-down position, the bore extending in a substantially horizontal direction referred to as the axle installation direction, between a first open end and a second open end are disclosed. The method includes a) supplying a mobile bearing structure (30) comprising means for moving the axle (12) which are able to move along a direction substantially parallel to the axle installation direction, b) installing the axle (12) on the means for moving the axle, c) aligning the axis (C) of the axle (12) with the axis (B) of the bore (14), and d) inserting the axle (12) into said bore (14) of the bogie (16) by moving the means for moving the axle (12) along the direction substantially parallel to the axle installation direction.

Abstract: A gantry crane and associated method of erection, the gantry including a frame having at least three first members; a longitudinal rail supported by the frame; and at least three second members extending between a first end portion and an opposite second end portion. Each second member can be connected to the frame by means for rigid connection and continuous rotational movement of the second member relative to the frame between a first position in which the second member forms an angle of less than 90° with the first plane and a second position in which the second member is substantially perpendicular to the first plane.

Abstract: An intake manifold for an internal combustion engine having a cylinder head is disclosed. The intake manifold includes at least one intake pipe with an intake flange for leak-free attachment of the manifold to the cylinder head by way of a sealing element. A bypass line is provided for feeding a secondary gas into the intake opening of the internal combustion engine. The secondary gas is fed into the bypass line through a connection, preferably a hose connection. The bypass line is formed by a groove in the intake flange which is open in the direction of the cylinder head and delimited on one side by the intake flange and on the other side by a sealing element. The connection is connected to one end of the groove, and the intake opening is connected to the other end of the groove.
