Long-lasting energy supply system for STS cranes

Monobeam, double trolley, gooseneck, shuttle boom or lattice girder crane: for the efficient loading and unloading of ships, various types of large-dimensioned ship-to-shore cranes are used, all of which place high demands on the function and reliability of the energy supply systems used. The operator must always be able to rely 100% on both the energy chains and cables - even under heavy loads, severe weather conditions and aggressive corrosion. With a broad portfolio of robust energy chain systems, intelligent sensors for condition monitoring or predictive maintenance, we help our customers achieve this goal.

i.Cee

Predictive maintenance with i.Cee

Thanks to intelligent software in combination with sensors on the energy chains, unplanned downtimes of cranes are a thing of the past. The i.Cee consists of sensors and software that report possible maintenance needs on the energy chain at an early stage, even before damage or even breakdowns can occur. Expensive plant downtimes are avoided and safety is increased.

i.Sense

Condition monitoring with i.Sense

The intelligent i.Sense sensor system and software monitors the condition of the energy chain on the crane around the clock. While heavy loads, long operating times and severe weather mean high loads for STS cranes, i.Sense helps to ensure operational safety. In the event of problems, the software can initiate an emergency stop to prevent major damage.

Clamps

CFXL chainfix clamps

Since STS cranes often have particularly long travels, high loads and forces prevail, especially in the area of energy supply. In order to relieve the heavily stressed cables in the chain, chainfix clamps are used. With simple retrofitting, they allow strain relief even for hoses and cables with large diameters.

Ship unloading crane

Roller energy chain on gigantic ship unloading crane in Rotterdam

A P4.1 series roller energy chain is in operation at the Port of Rotterdam, one of the largest bulk handling ports in Western Europe. On the ship-to-shore crane, it operates 24/7 continuously over 100 metre travel and without incident. So far it has completed more than 9,000 operating hours.

STS crane energy chain

e-chains replace festooning systems and save time and money

With this ship unloading crane, the entire crane girder can be moved vertically. However, the previous solution of energy supply systems with free-hanging cables was very vulnerable, as they would snake into each other every time in strong winds, resulting in high maintenance costs. Since the replacement with new energy chains, however, the cables have been safely guided.

Energy chain

12 STS cranes in Antwerp equipped with heavy duty energy chains

For this project in Antwerp, twelve ship-to-shore cranes were equipped with robust HD energy chains from the 5050R.17.300.0 series. All energy chain systems installed in a channel in the floor were equipped with stainless steel guide troughs. The travels of these cranes are up to 500m.

STS port crane energy chain

14 gantry cranes at the Port of Hamburg equipped with energy chains

Fourteen container gantry cranes at HHLA Container Terminal Altenwerder (CTA) are equipped with energy chains to supply the gantry trolleys with energy and signals. The chainflex cables have been working trouble-free under very high loads for twelve years now and have already covered quite a few 1000 kilometres in this time. At that time, CTA was a pioneer in the use of energy chains and highly flexible cables. Today, it has become accepted worldwide.

Flexible installation options for energy chains on STS cranes - Be prepared for any case

Depending on the application situation and type of crane, various types of installation of an energy chain system are available. In addition to the usual installation on top of the crane girder, the side attachment for example protects against strong crosswinds, whereas an installation of the e-chain under the crane girder shields it as far as possible from snow, rain and ice. We can provide you with the right energy chain and installation option for every situation.
