5 Use
5.1 System operation
The HCT is a tool where the hydraulic pump is integrated in the tool. The hydraulic pump is driven by a
pump handle. This pump displaces hydraulic oil and is capable of building up pressure. The hydraulic
pump is connected directly to the hydraulic cylinder.
The hydraulic cylinder contains a piston that can move axially. If the cylinder is pumped full from the
bottom, pressure builds up beneath the piston so that it is pushed to the outside. If the cylinder is
pumped full from the top, the piston is forced back into the cylinder.
In tools like cutters, spreaders and combi tools the axial movement of the piston starts a mechanism
that then makes a cutting or spreading movement.
