Abstract (en)
[origin: EP0018014A2] A device for moving a first part 23 of a formwork assembly relative to a second part 9 is disclosed which comprises at least one shoe 37 mechanically connected to the first part 23 which is slidable along a rail 43, the first part comprising an elongate member 36 having at one end a screw threaded bore which co-operates with a rotatable screw threaded member 47 which is retained 48 so that the screw threaded member can rotate but cannot move longitudinally. Elements having a low coefficient of friction may be provided between the shoes 37 and the rail 43. The invention is described with reference to an arrangement which moves soldiers 23 and also with reference to a self-climbing formwork where a shoe 57 slide along rail 56 on rotation of threaded member 66 by means of electric motor 72.
