Abstract

A cantilever supports a catenary to supply energy to a vehicle. The cantilever includes a cross-member adapted to be attached to a support structure, the cross-member extending along a longitudinal axis (X-X), and at least one attachment connected to the cross-member. The cross-member includes an outer surface, the outer surface including at least a first side having a non-circular shape in a section plane (II-II) that is orthogonal to the longitudinal axis (X-X). The attachment includes at least one collar encircling the cross-member, and the collar includes at least one contact face in contact with the at least first side.

First claim

What is claimed is:

1. A cantilever for supporting a catenary to supply energy to a vehicle, the cantilever comprising a cross-member adapted to be attached to a support structure, the cross-member extending along a longitudinal axis, and at least one attachment connected to the cross-member,
wherein the cross-member includes an outer surface, the outer surface comprising at least a first side having a non-circular shape in a section plane that is orthogonal to the longitudinal axis,
wherein the at least one attachment comprises at least one collar encircling the cross-member,
wherein the collar comprises at least one contact face in contact with said at least first side,
wherein each collar includes a flange, a screw and nuts to secure the screw to the flange,
the flange being placed on the first side of the cross-member,
the screw being placed on a second side of the cross-member that is radially opposed to the first side with respect to the longitudinal axis,
the flange receiving both ends of the screw to encircle the cross-member,
the flange comprising a contact face, the contact face being in contact with at least a part of the first side, and
wherein each collar further comprises an elastic plate comprising an inner face and an outer face,
the elastic plate being arranged between the screw and the second side of the cross-member,
the inner face of the elastic plate being in elastic contact with at least two points of the second side of the cross-member.

2. The cantilever according to claim 1 , wherein the contact face of the collar has a shape that is complementary with said first side.

3. The cantilever according to claim 1 , wherein the outer surface of the cross-member has a convex shape in the section plane.

4. The cantilever according to claim 3 , wherein the outer surface of the cross-member has a barrel-shape in the section plane.

5. The cantilever according to claim 1 , wherein the at least one attachment includes the cable clamp able to support a cable of the catenary.

6. The cantilever according to claim 1 , wherein the at least one attachment comprises two collars.

7. The cantilever according to claim 1 , wherein the cantilever comprises at least one cable support attached to the cross-member through one of the at least one attachment.

8. The cantilever according to claim 7 , wherein the at least one cable support comprising a registration bracket and a steady arm,
the registration bracket being attached to the cross-member through the attachment,
the registration bracket extending along a corresponding axis,
the registration bracket comprising an outer surface having a non-circular shape in a plane orthogonal to the said axis,
the steady arm comprising a proximal end attached to the registration bracket through an intermediate attachment,
said intermediate attachment comprising at least one contact face in contact with at least a part of the outer surface of the registration bracket that has the non-circular shape in said plane orthogonal to said axis.

9. The cantilever according to claim 1 , wherein the cantilever includes a guy-wire for supporting the cross-member, the guy-wire extending along a corresponding axis,
the guy-wire including a proximal end adapted to be attached to the support structure, and a distal end attached to the cross-member through the at least one attachment.

10. The cantilever according to claim 9 , wherein the at least one attachment of the guy-wire includes a cable clamp, said at least one attachment and said cable clamp forming a cable support.

11. The cantilever according to claim 9 , wherein the guy-wire includes a turnbuckle to enable the tuning of the length of said guy-wire along the corresponding axis.
