Abstract
A railway-rail-lifting device for lifting a railway rail comprises an arm (105) and a roller (110) rotatably mounted to the arm (105). The arm (105) is operable to be rotated to bring the roller (110) to bear on the rail such that the roller (105) exerts a lifting force thereon. Securing means are operable to releasably secure the device to a rail fastening assembly.
Claims34
A railway-rail-lifting device (100;
- 1100;
- 1100′) for lifting a railway rail (210), the device (100;
- 1100;
- 1100′) comprising:
- an arm (105;
- 1105);
- and
- a roller (110;
- 1110) rotatably mounted to the arm (105;
- 1105);
- the arm (105;
- 1105) being operable to be rotated to bring the roller (110;
- 1110) to bear on the rail (210) such that the roller (110;
- 1110) exerts a lifting force thereon;
- the device further comprising securing means (160;
- 2000;
- 5000) operable to releasably secure the device (100;
- 1100;
- 1100′) to a rail fastening assembly.
A railway-rail-lifting method for lifting a railway rail (210), the method comprising:
- rotating the arm (105;
- 1105) of a device (100;
- 1100;
- 1100′) comprising an arm, a roller rotatable mounted on the arm, the arm being operable to be rotated to bring the roller to bear on the rail such that the roller exerts a lifting force thereon, and securing means operable to releasably secure the device to a rail fastening assembly to bring the roller (110;
- 1110) to bear on the rail (210) such that the roller (110;
- 1110) exerts a lifting force thereon.
Railway-rail-lifting apparatus for lifting a railway rail (210), the apparatus comprising first and second devices (100;
- 1100;
- 1100′), each of said devices comprising an arm, a roller rotatable mounted on the arm, the arm being operable to be rotated to bring the roller to bear on the rail such that the roller exerts a lifting force thereon, and securing means operable to releasably secure the device to a rail fastening assembly the rail (210) having a head section and the head section having an underside face, wherein the arm (105;
- 1105) is operable to be rotated such that the roller (110;
- 1110) is brought to bear on a portion of said underside face, wherein the rail (210) has first and second underside faces on opposite sides of the rail (210), and wherein the arm (105;
- 1105) of a first one of the said devices (100;
- 1100;
- 1100′) is operable to be rotated such that the roller (110;
- 1110) of the first device (100;
- 1100;
- 1100′) is brought to bear on a portion of said first underside face, and wherein the arm (105;
- 1105) of a second one of the said devices (100;
- 1100;
- 1100′) is operable to be rotated such that the roller (110;
- 1110) of the second device (100;
- 1100;
- 1100′) is brought to bear on a portion of the second underside face.
