2.
Assemble the mounts by inserting either a dummy load cell or the actual
load cell into the hole in the top plate loading bracket, then installing the
load pin and locating pin
*
. Then pass the load cell bolts through the ends
of the load cell and load bars and thread into the base plate. Tighten by
hand.
The arrow on the load cell should point in the direction of the load.
3.
Lift and block the vessel to the same height as the assembled mounts.
4.
Remove the block from one support point and slide mount into position.
5.
If the mount is being fitted under the leg of a vessel, verify that the leg’s
center line passes through the center of the top plate (through the center
of the load cell).
6.
Lower the corner or side of the vessel carefully onto the top plate. The
force of a vessel weighing several tons can damage a load cell if
dropped only a fraction of an inch.
7.
With the top plate positioned approximately level, mark holes for
attaching the top plate to the vessel’s mounting surface. Drill holes and
attach top plate loosely to vessel with suitable fasteners.
8.
Repeat steps 3-7 for the mounting assemblies at the remaining corners
or sides.
9.
Verify that there is no initial misalignment between the base plate and
top plate and that the load cell is in the center of the hole in the top plate
loading bracket. Relocate if necessary.
10. Attach the base plates to the foundation using suitable anchors for
concrete or by bolting or welding to a steel structure. Verify that the base
plates are no more than ±0.5° out of level. Shim as necessary.
