RTN/M2
Mounting of load cells up to a max. capacity of 4.7 t (see Fig. 7.1):
 Remove the anti‐liftoff device by undoing the 2 hexagonal screws
 Loosen the lateral stops
 Use a suitable lifting device to lift the respective tank base by approx.
10 mm
 Undo the centering discs
 Remove the dummy with the mounting base of the RTN by lifting lightly
and withdrawing to one side (for pendulum bearing version, with pendulum
bearing)
 Remove mounting from dummy and fit to load cell; tightening torque of the
4 screws: 4 Nm
 Secure and position load cell with mounting base by means of centering
discs on the lower module plate. Apply the enclosed grease to the load in-
troduction parts of the load cell.
 With the pendulum bearing version, position the pendulum bearing on the
load cell. Also apply grease.
 Slowly lower the tank while making sure that the load buttons engage with
the corresponding seats without suffering damage.
 Vertical module alignment by inserting or removing the five 1‐mm‐thick
spacer plates underneath the upper module plate.
 Mount and adjust the anti‐liftoff device by inserting plates underneath such
that an air gap of about 1 mm results (see Fig. 7.1) with the tank empty.
 First adjust and then lock the horizontal stops. The U‐shaped bracket ac­
counts for the stiffness of the stops and has to be fastened with the stop
screws. Please refer to the Specifications in Chapter 5 for the maximum
permissible horizontal shifts (distance from the stops). The stay rods al-
ready have been adjusted at the factory to ensure that the load introduc-
tion parts are aligned with the load cell in the rod direction. Should a read-
justment prove necessary, the rod end bearings subsequently have to be
carefully locked.
Mounting of load cells up to a max. capacity of 10 t, 22 t and 33 t (see
Fig. 7.2):
 Remove the anti‐liftoff device by undoing the 2 hexagonal screws
 Use a suitable lifting device to lift the respective tank base by approx.
10 mm
 Remove the load cell dummy without the mounting base with thrust piece
by lifting lightly and withdrawing to one side (for pendulum bearing version,
with pendulum bearing)
