5 Operation
5.1

System operation

The GCT is a tool where the hydraulic pump is integrated in the tool. The hydraulic pump is driven by a
battery pack or from an external electric power source. 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.
