2.3 Mechanical features
The mechanical features described in this chapter are
standard provided on this light tower. For all optional
mechanical features, see “Overview of the
mechanical options” on page 63.
2.3.1 Engine and alternator
The alternator is driven by a fluid-cooled diesel
engine. The engine’s power is transmitted through a
direct disc coupling.
The light tower houses a single bearing alternator
with a dedicated excitation system for light tower
application.
The synchronous brushless alternator has Class H
rotor and stator windings in an IP21 housing.
2.3.2 Cooling system
The engine is provided with a water cooler. The
cooling air is generated by a fan, driven by the engine.
2.3.3 Safety devices
The unit controller monitors the engine and electrical
parameters and generates warning and shutdown
signals when the parameters reach a preset treshold
value.
2.3.4 Bodywork
The alternator, the engine, the cooling system, etc. are
enclosed in a sound-insulated bodywork that can be
opened by means of side doors.
The light tower can be lifted by using the lifting eye
integrated in the bodywork (roof). To be able to lift
the HiLight H4 by means of a forklift, rectangular
holes are provided in the frame at the left and right
side of the unit.
2.3.5 Control panel
The control panel grouping the controller, fuses,
automatic switches sockets, etc., is placed at the right
side.
2.3.6 Data plate and serial number
The light tower is furnished with a data plate showing
the product code, the unit number and the power
output (see “Data plate” on page 80).
The serial number is located on the frame, on the left
side of the towbar.
Indicates the earthing connections on
the light tower.
Indicates the danger of touching
rotating parts of the unit.
Indicates the different
service packs, liquids and
critical parts. These parts
can be ordered to the
factory.
