Machinery House / Machinery
The machinery house and the machinery located inside are
protected against weather. Cooling is achieved via hydraulically
driven fans.
Also situated in the machinery house are the electrical switch
compartments, containing the in-house designed Liebherr
Litronic
® crane control system (VME-CAN-Bus 2-line).
Features of Liebherr Litronic ®
control system
s¬ Availability of spare parts: 25 years
s¬ All upgrades are downward compatible
s¬ Ease of maintenance – no additional software specialist
required
s¬ Designed and tested for maritime environment
s¬ Spacious arrangement for optimal service accessibility
The crane drive consists of a splitter gearbox feeding variable
displacement axial piston pumps for the hoisting, slewing and
the luffing gear. The splitter gearbox can either be driven by an
electric motor or alternatively by a diesel motor.
Slewing Platform and A-Frame
The slewing platform is designed to house the machinery compartment, the luffing winch, the counterweight (if installed),
the slewing gears and the operator‘s cabin.

Closed hydraulic circuits technology is used for maximum
performance and high efficiency. This technology guarantees
a highly responsive, smooth and sensitive operation with a
minimum of components, maximising the operating safety even in
continuous operation or low/high ambient temperatures (-25°C to
+45°C). As an option an arctic temperature package is available,
which allows to operate the crane within an ambient temperature
range of -40 °C to +45 °C.
s¬ Immediate and short system reaction times for rapid and safe
operation
s¬ All crane motions are carried out continuously, precisely and
simultaneously with adjustable speed and load
s¬ High performance density requiring a minimum of power
s¬ Faster acceleration and deceleration due to low masses of
inertia
s¬ Easy fault-finding and diagnosis due to spare circuits for each
crane function
s¬ Reduced service and maintenance costs compared to open
loop systems of equivalent capacity
s¬ Up to zero reverse power
