- the movement of both gripping mechanisms can take place synchronously, but optionally also a device is provided in which the respective
- page 4 gene gripping mechanisms are independent of each other and are movable, be possible.
- the suspension and movement of the gripping mechanism is designed in the form of an eccentric cam, in which a movement of the clamping clamps from the pre-assembly to the mounting position takes place so that the tension clamp in a predetermined amount of at least 15 mm, preferably at least 20 mm , Particularly preferably at least 30 mm, is spent above the angle guide plate in the area above the rail foot, to then be lowered there on the rail and the angled guide plate down.
- the tension clamp in a predetermined amount of at least 15 mm, preferably at least 20 mm , Particularly preferably at least 30 mm, is spent above the angle guide plate in the area above the rail foot, to then be lowered there on the rail and the angled guide plate down.
- the mounting device is connected to a preferably be placed on the rail and movable on this drive device and / or connectable.
- the drive means is able to drive the movements of all mechanisms and devices of the mounting device, including the hydraulic and electrical or motorized-mechanical.
- the transfer of the clamps from their mounting position takes place in their pre-assembly by lifting the clamp when unscrewing the clamp screws.
- the gap present between the rail sleeper and the rail is bridged by the lifting movement when the tension clamp is raised sufficiently high.
- the transfer of the tension clamp from its pre-assembly into its mounting position by pivoting the gripping mechanism via spring force so that a jamming of the machine in case of unexpected collisions, for example in the presence of gravel between tension clamp and rail, is avoided. If the machine is not stopped, the mechanics will not cause any tension and can easily be released from the rail again.
- the hydraulic system is automatically de-pressurized during an emergency stop.
- page 6 Tik is provided within the system and / or Moniagevorraum invention, the automation of the assembly process by simple and preferably fully automatic insertion of the clamps in their mounting position and placement of the device for screwing and unscrewing at least one clamp screw is supported with simple and particularly effective means. As a result, a consistently high screwing accuracy is finally achieved, which makes it possible to avoid manual recalibration on the construction site, in particular manual reworking with a torque wrench.
