Abstract
This hand tool is designed for installing and extracting the elastic fastenings of railroad rails. It comprises a base body, mounted movably to the underside of which is an active part which acts on the fastening that is to be inserted or removed. A rotating head or a rotating part that can be pivoted about an essentially vertical axis is provided on the top of the main body, this head carrying a hand-powered member such as a push bar which extends to the side of said head. A force-multiplying transmission, which may for example be hydraulic, connects the hand-powered member to the active part. In this way the hand-powered member can, independently of the use position of the active part, be placed in a suitable orientation, particularly inside a safe zone.
Claims19
A hand tool for inserting and removing rail fastenings, particularly for installing and extracting inner or outer elastic fastenings, comprising, in combination:
- a main body,
- an active part designed to act on a fastening that is to be inserted or removed, the active part being mounted movably underneath the main body,
- at the top of the main body, a rotating head or rotating part that can be pivoted about an essentially vertical axis,
- a hand-powered member, such as a push bar, mounted or mountable on the rotating head or rotating part and extending to the side of this rotating head or rotating part, and
- a force-multiplying transmission between the hand-powered member and the active part,
- the rotating head or rotating part being positionable angularly independently of the use position of the active part, in such a way as to place the hand-powered member in a suitable orientation, particularly within a safe zone.
