  • the strain gauges 19 are operated in a circuit via lines attached to their terminals. The measured load is transmitted to a control device.
  • the loads on the other holding devices 14 are transmitted to the control device.
  • the load values are summed up and compared to a defined, damage to the leader preventing the threshold value. If the threshold value is exceeded, the pressure cylinder unit or units 18 are actuated until the specified maximum value is undershot. This can be done by reducing the pressure or a compensation of the torques about the center plane 16 of the base support 12. Compensation occurs, for example, in that the pressure cylinder units 18A, 18B exert more pressure on the respectively associated sheet pile wall element and / or the pressure cylinder unit 18D exerts more tension on the associated sheet pile wall element. Thus, for further pressing in of the pressure cylinder unit 18C associated sheet pile element also more pressure on this sheet pile wall element by the pressure cylinder unit 18C are exercised.
