5 Operation
5.1 System operation
5.1.1 General
A system is an assembly of a hydraulic pump, hose(s), and one or more tools.
The hydraulic pump is driven by an internal combustion engine, electric motor, pneumatically or by hand
or foot power. This pump displaces hydraulic oil and is capable of building up pressure. The hose is for
transporting the hydraulic oil between the pump and the tool.
The tool has a hydraulic cylinder containing 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.
The direction of the movement of the cylinder is determined by a control valve, the so-called deadman's
handle. This deadman's handle can be turned to the left or the right, thus determining the direction the
piston moves. In the neutral position no pressure is built up in the cylinder and the oil flows back to the
pump without pressure. If the deadman's handle is released, it returns automatically to the neutral
position and the piston immediately stops moving.
In tools like cutters, spreaders and combi tools the axial movement of the piston starts a mechanism
that makes a cutting or spreading movement.
The hose is the piece of equipment that connects the pump to the tool, thus creating a closed system.
