4. Functional description
4.1 Description
The cutters and combi tools have been designed in such a way that a hydraulically operated
piston activates mechanical joints symmetrically to open or close a set of two opposite blade
arms, thus enabling objects to be cut.
The spreaders operate according to a similar principle. They, too, have been designed in
such a way that a hydraulically operated piston activates mechanical joints symmetrically
to open or close a set of two opposite spreader arms. This movement can then be used to
spread open, squeeze or pull open objects.
The rescue rams are double-acting hydraulic cylinders. Extension and retraction takes place
hydraulically.
On all devices, the movement is activated by means of a valve in the form of a star grip.
All devices guarantee the dead man's switch and the full load-supporting function when the
star grip is released.
LUKAS eDRAULIC devices do not need to be connected to an external hydraulic source
(e.g. a motor pump). The hydraulic pressure required is generated within the body of the
device.
Either a battery or an external power supply must be connected as an energy source.
You can choose which energy source you wish to use. Both the battery and the power unit
can be plugged into the opening provided in the body of the tool. Both will lock in place au-
tomatically.
When using batteries as an energy source, you have almost unlimited freedom of movement
when working, i.e. there are no cables or hoses to hinder you. You can extend the operating
time of your eDRAULIC device by using several batteries. The batteries can be recharged
after use, using a suitable external charger
If you use an external power supply, the operating time is essentially unlimited; this is only
restricted by the external power source and the thermal switch in the power unit.
To allow you to select the best possible energy supply for your eDRAULIC device, neither the
battery nor the power supply form part of the delivery scope. You will fi nd suitable batteries
and power supplies in the LUKAS accessories list.
eDRAULIC devices are equipped with lighting as standard so that work can be carried out in
conditions where visibility is poor.
The light-emitting diodes attached on the operating side light up the work area. The main
switch has also been provided with a light, so that you can see at a glance whether the de-
vice is switched on. When exchanging the battery or power supply, the connection slot will
be lit up for approximately 30 seconds.
