The Norwegian Port of Borg has invested in Liebherr‘s LPS 420 E crane to help meet its climate goals while offering multipurpose cargo handling options.
The Liebherr portal slewing crane will be the first of its kind delivered in Norway and reportedly exceeds the average turnover of comparable electric driven cranes in the market.
All crane movements such as luffing, hoisting, slewing, and travelling are done by electric motors.
The LPS 420 E can be supplied with high or low voltage, depending on the transformer requirements. This ensures that Port of Borg can fulfill its logistical operations while greatly reducing its environmental footprint.
The multi-purpose port handles all types of cargo like containers, bulk, general cargo, and heavy lift.
It is the third biggest container port in Norway, with 67,249 TEU in 2021, which is an increase of 14 per cent from 2020.
The contract for the new crane was entered into in March 2022.
“This is a large investment for Borg Havn,” said Port Director, Tore Lundestad.
“Renewing and modernising our crane fleet in line with harbour activity is crucial to us.”
Lundestad added that among the main reasons for investing in the LPS 420 E is its more environmentally friendly profile, which allows reduced emissions and noise in the area.
Based on the modernised electric infrastructure of the port, the LPS 420 E is equipped to provide optimal and safe operations.
Due to the Liebherr active-front-end frequency converter, deviations in the voltage supply can be compensated easily for safe and stable operation.
To accommodate potentially limited space and any harsh environmental conditions, a liquid-cooled and highly efficient performance capacitor system was implemented.
A reported turnover of up to 1,200 tonnes per hour allows the new Liebherr electric crane to exceed the average turnover of comparable all-electric cranes in the market.
With up to 30 cycles per hour, the LPS 420 E is a seemingly viable solution when it comes to container handling performance.
The crane can be fitted with various types of fixed or telescopic spreaders on a 60-tonne load chart for twin-lift container operation.
A maximum outreach of up to 48 metres allows for ships up to Panamax class size to be served.
The main components of the E-drive are liquid cooled and the heat is dissipated by heat exchangers.
The fully closed liquid cooling system in combination with the heat exchanger are installed on top of the slewing platform.
According to this, no overpressure unit is necessary to prevent dust coming inside the machinery house, which is a benefit for cranes working in dusty environments.
