In the extended state, the beam’s n

In the extended state, the beam’s new docking unit has more lateral play in order to balance outtrack gauge tolerances in the steel structure. When retracted, the guide rails are centred again. Thismay give rise to forces in the axial direction of the pallet rollers. If at all possible, these lateralforces should be avoided at the weighing units. To achieve this, the roller movement of the pull unitand the undocking movement that causes the docking mechanism to be centred should be overlaid.Equally, transverse forces may arise during docking at the steel structure due to the adaptation ofthe docking mechanism. These are again dissipated by moving the cross lifter and the pull unitsimultaneously.
