The company is involved in the ports and terminals business. During container crane operation, the crane will lift containers averaging 20 tonnes in weight. The container will be transported using a trolley truck over a distance of more than 50 metres between the vessel and the landside for container loading and discharging operation.
The trolley will transverse horizontally on 2 sets of rail track. The total weight is between 40 tonnes (empty trolley) to 90 tonnes (when carrying full laden containers). As the trolley’s wheels transverse over the rails, there will be compression and decompression force exerted on the base of the rails.
The company is seeking energy harvesting technologies to supplement the electrical energy usage during container handling operation.
The company is seeking energy harvesting technologies that can be ideally mounted underneath the base of the trolley rail that convert mechanical and compression force to electrical energy. The electrical energy generated from these harvesting technologies will be connected to the crane electrical system to supplement its electrical energy use.
The desired technical specifications are as follow:
