In crane construction on ports, extremely long mechanical distances mean that operating safety is particularly stringent and costly downtimes avoided as much as possible.
It is extremely expensive for ship owners and terminal operators if a ship stays in port longer than necessary due to a crane breakdown and other technical problems.
This is where energy chain systems play a vital role, ensuring power and data is transmitted over distances of several hundred metres.
Energy chain specialist Igus – represented in Australia by Treotham Trading - has now also installed a total of 12 new ship-to-shore cranes at the Port of Singapore. The distance traveled by these cranes is up to 500m. All of the energy chain systems installed in a channel on the ground were fitted with stainless steel guide troughs as protection against adverse weather conditions.
All 12 systems work in three continuous trough guides of a total length of 900m – the length of the quay is 906m. The energy chain systems transmit data from each crane via LWL and supply power via three 6/10 KV medium voltage cables per crane.
All of the cables are from the igus “Chainflex” range. From a system point of view, this has the advantage that an individual crane can be removed from the network while the other cranes are operating.
The entire channel is enclosed with cover plates which are opened for each crane during a crane drive with a combination of plate lifting trucks and energy chain moving ends.
