7.2 Drive unit with pump and motor
7.2.1 Motor
A 24V DC electric motor (2) with a power of 480 W is used for driving the hydraulic pump.
7.2.2 Hydraulic pump with valves
The hydraulic pressure is produced by a LUKAS radial piston pump (1) with:
-
low pressure circuit (up to 8 MPa) = LP
- high pressure circuit (up to 63 MPa) = HP
(10 bar = 1 MPa)
Necessary valves are also integrated in the pump unit:
-
switch-over from low to high pressure is made automatically by a switch-over valve (3)
- the max. system pressure is limited by a pressure relief valve (4) set to 63 MPa
- with the dump valve (5) pressure can be released manually.
7.2.3 Oil container
The hydraulic circuit is designed as a closed loop without connection to the atmosphere. There-
fore the hydraulic oil is stored in a flexible diaphragm reservoir which compensates oil level
changes occuring during operation of rescue tools.
7.2.4 Hydraulic hoses
Two hoses are permanently connected with the pump unit. The pressure hose (mounted at
port ”P”) is equipped with a quick- connect plug (type StNi61, closed ended). Pressure can be
released from the hose through the drain valve on the pump.
7.2.5 Quick connect couplings
A rescue tool can be connected to the pump by means of non-interchangeable quick couplers.
7.3 The battery
The battery is mounted inside a separate housing which can be connected with the pump unit by
means of a slide-lock mechanism. The housing has a connector for the charging cable.
7.4 The carry harness
For comfortable transport a carry harness is provided. With the harness the pump unit can be
accomodated on your back so that both hands are free for rescue work.
By means of the handle on top of the harness the pump can be carried, as well.
