1. A rail clamp handling arrangement, for moving a clamping element from a position in which said element fastens a rail to a railroad sleeper to a sleeper releasing position or vise-versa, comprising:
a support structure having a lower part with a central rail fitting recess and arranged to extend transversally in relation to the longitudinal extension of the rail, wherein at each outer end portion of said lower part there is arranged connection means that provide pivot points at an intermediate point of a pair of pivotable lever arms, said pair of lever arms being arranged mirror symmetrically, a power and transmission arrangement arranged to simultaneously move an upper part of said lever arms via an upper pivotal connection, a lower part of said lever arms comprising contact devices arranged to move a clamping element, wherein said power and transmission arrangement includes a power unit in the form of an electric motor and a rotatable threaded shaft having oppositely arranged threads to transfer torque applied via said power and transmission arrangement into pivotal mirror wise movement of said lever arms.
