<p>The equipment consists of several sets of hydraulic power cylinders (8) with counter plates (9), guide tubes (10) and extension rods (11). The sets of hydraulic power cylinders are applicable on suitable places of the crusher walls. In these places suitable design provisions are made on the walls to fix the particular power cylinder to the outside of the wall. By applying hydraulic pressure it is possible to push out from its place the fixing wedge (6) as well as the jawplates (4, 5). When jawplates (4, 5) are removed, also side plate (7) can be removed in a similar manner by applying the power cylinder through the side wall of the crusher.</p> |
