Energy-saving Mobile Cranes Conquer The Port of Neustadt

NEUSTADT/GERMANY, 03.04.2015 – Europe’s largest port for conventional freight makes use of the latest crane technology from Sennebogen. A mobile undercarriage and an intelligent energy recovery system spell a happy logistics client.

Started at a very small scale in 1877, BLG (“Bremer Lagerhaus Gesellschaft”) has transformed itself into a global logistics service provider.  From shipping containers to automobiles, it moves material along every route of transport. BLG handles around two million tons of cargo per year at the Port of Neustadt in Bremen. It is Europe's largest terminal for conventional, non-containerized, freight.

Challenges

This mammoth handling was proving a challenge for the company, which deployed the conventional rope crane method till very recently.
In order to handle the cargo in an efficient manner, BLG decided to acquire a state of the art mobile crane over the earlier practiced rope crane method. For the BLG management, the decisive factors while making the acquisition of the new crane were high flexibility and mobility as well as low operating and service costs. Another challenge in front of the company was a fast turnaround time.  Just a few hours after arriving, ships must depart once again for the high seas, carrying shipping containers, general cargo, large-diameter pipes, timber products, whole industrial machines and heavy cargo.

Decision Making Process

After carefully evaluating the various options, BLG decided to acquire a Sennebogen mobile crane. Operational since mid 2014, the mobile crane has been providing its services in an innovative and efficient manner, explains BLG.
The 165-ton handling machine with its mobile undercarriage has four axles and can reach a top speed of 5 km/h due to its fully hydraulic drives.  The crane's day-to-day cargo largely consists of timber products and large-diameter pipes. It can complete a cycle in just two minutes, a marked improvement from previous arrangement. Its mobile undercarriage allows it to operate from different locations at the port.  With a load bearing capacity of 165 tons and 27 meter reach, the crane can service even the largest ships easily.

Ease of Operations and Energy Efficiency

For operators, the elevated Maxcab industrial cab provides an ideal overview of the work area, even into the ship's cargo hold. Simple maintenance tasks can be completed quickly due to the machine's clear design. A smart control system provides all machine parameters and data on a clear display.
However, it’s not merely the ease of operations. The innovative Green Hybrid energy recovery system in the crane saves up to 30% more energy than conventional concepts.  Operating on a principal similar to a compressed spring, a third hydraulic cylinder, placed directly between the two hoist cylinders, stores the energy produced by lowering the boom in compressed gas cylinders. This accumulated energy is then provided during the next stroke.
Commenting on ease of operations due to new acquisition, Andre Heidkrüger, head of Star Shipping Profit Center at BLG Cargo Logistics says "Our investment in a new mobile port crane is paying off. We can use the SENNEBOGEN 875 without restriction anywhere at the port - regardless of the cargo being handled. Not only do we work quickly, but also more efficiently and with fewer costs, and that's good enough for us."
