Ports and Harbors play a significant role in our world as major trade hubs of global economy. Cargo handling efficiency has a direct impact in our economy. The faster and more efficiently containers are managed, the better it is for the port and for the whole supply chain.
In a container port containers are transshipped between different transport vehicles and containers has to be moved from vehicle to another. Typically a crane is used for loading and unloading the containers.
Different types of cranes are used for cargo handling: ship-to-shore cranes, rail mounted gantry cranes, rubber tired gantry cranes, ship unloaders, etc. Since a container terminal can run 24/7, thus same availability of the cranes is critical.
In order to keep the cranes available, it is necessary that the access to cranes is quick and safely in all condition to minimize downtime. Standard cranes come with ladders only. It can take long time for a person to climb up all the ladders and it can be unsafe in bad weather conditions to access the crane. The maintenance of crane can consume a lot of time and effort since also material needs to be transported to the top of crane.
