6.2.3 Crusher with rubber dampers on a steel supporting
structure
See appendix A: Installation drawings .
Design the steel supporting structure and its reinforcement to match the load
information in the installation drawings. Consider also the bearing strength
and nature of the ground under the foundation.
Installation
a) Make sure that the crusher’s mounting points are level. Use shims to
level. Max deviation at load application point: ±1 mm.
b) Carefully clean any dust and oil from the area beneath the crusher.
c) Install the four rubber dampers on the crusher’s feet. Make sure that the
lower fixing plates (7) are attached to the dampers.
d) Lower the crusher until the lower fixing plates (7) are resting on the
supporting structure.
e) Center the crusher over the discharge opening.
f) Spot weld the lower fixing plates (7) to the supporting structure.
g) Remove the screws (5) and washers (6) from the upper fixing plates (3).
h) Lift the crusher away from the rubber dampers.
i) Weld all around the lower fixing plates (7) to the supporting structure.
See drawing in
appendix A: Installation drawings .
j) Lift the crusher onto the rubber dampers.
k) Fit the washers (6) and screws (5).
