4. Functional description
4.1 Description
The cutting and combination devices 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. These, 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 be used to spread
open, squeeze or pull open objects.
The rescue rams are double-acting hydraulic cylinders. Extension and retraction takes place
hydraulically.
For 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). Generation of the required hydraulic pressure takes place 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 accumulator battery and
the mains power unit can be inserted into the opening provided in the body of the tool.
They are then automatically locked into position.
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 are making use of an external power supply, the device can be used for an almost
unlimited time. This time is only limited by the external energy source and the overheating
switch of the power supply.
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 bat-
teries and power supplies in the LUKAS accessories list.
eDRAULIC devices come with standard light fi ttings to facilitate work under poor light
conditions.
The light-emitting diodes attached on the operating side light up the work area. The
main switch has also been equipped with a ring light, so that you can immediately detect
whether the device is switched on or not. When exchanging the battery or power supply,
the connection slot will light up for approximately 30 seconds.
